Wren Terms of Use

Effective: 30 July 2026

These are the terms you agree to when you use Wren. We have tried to write them so that a person can actually read them, on a phone, on a tired afternoon. Where the law makes us say something in a particular way, we say it and then we say what it means.

If you do not agree with these terms, please do not use Wren. Deleting the app removes everything it holds.

Wren is made by Sritej Padmanabhan ("we", "us"). You can write to us at hello@wrenapp.care.

1. The short version

• Wren is a diary. It records and organises what you tell it. It does not diagnose you, treat you, monitor you, or prescribe anything. Never change a medicine because of something in this app.
• Wren is not an emergency service. If somebody is in danger, ring emergency services.
• Wren's chat and the doctor's letter are written by an AI. They can be wrong. Check anything that matters.
• Most of Wren is free forever. Wren Plus is a paid subscription bought through Apple, and it renews by itself until you stop it.
• The care circle shares health information about you with a person you name. You choose what they see, and you can stop it at any time.
• Be decent to other people in the community. Anything abusive gets removed and the account behind it gets ended.

The rest of this document is the detail.

2. Who may use Wren

You must be at least 18 years old to buy anything in Wren. Wren is not designed for or directed at children.

You may use Wren for yourself, or on behalf of somebody you care for, if they have asked you to or if you are lawfully entitled to act for them. If you set Wren up for another person, you are telling us that you have their agreement, or the legal authority to act in their place.

You may not use Wren if you are in a country the United States has embargoed, or if you are on a United States government list of prohibited or restricted parties. There is more about this in section 15.

---

3. Wren is not a medical device

This is the most important thing in this document, so it gets said plainly.

Wren records what you tell it and organises it. That is all it does.

• It does not diagnose. It does not tell you what you have, or how far along it is.
• It does not treat. It does not tell you what to take, how much, or when to change anything.
• It does not monitor you. It has no alarm that watches your body. Nobody is on the other end of it.
• It does not prescribe, and it is not a pharmacy.
• It is not a substitute for a doctor, a nurse, a pharmacist, a therapist, or any other professional. It never will be.

Wren is a general wellness and record-keeping tool. It is not cleared, approved, registered or certified as a medical device by the FDA, the MHRA, the EU authorities, or anybody else, and we do not present it as one.

Never start, stop, or change a medicine because of anything Wren says, shows, counts, or leaves out. Talk to your doctor or your pharmacist. If your medicine list in Wren is wrong, the list is wrong, and the bottle in your hand is the truth.

Wren's medicine reminders are a convenience and nothing more. They can fail. A phone can be off, out of battery, out of signal, on silent, or have notifications turned off. Do not build the safety of your medicines on a reminder from this app or from any app.

Wren counts how much of a medicine is left from the doses you told it about. It is an estimate from your own numbers, it deliberately errs towards warning you too early, and it never says anything about what to take. It is not a supply of medicine and it does not order one.

The walking figures Wren can read are measured by your iPhone, not by Wren. Wren copies them onto the page you take to your appointment and says nothing at all about which way they are going. Any reading of them belongs to your clinician.

4. Wren is not an emergency service

Wren cannot summon help. It cannot call an ambulance. Nobody at Wren is watching your account, and there is no monitoring centre.

If somebody has fallen and cannot get up, cannot breathe, is choking, is having a stroke or a heart attack, has taken too much of something, or is in danger in any other way, ring emergency services. In the United States that is 911. In the United Kingdom and Ireland that is 999 or 112. Elsewhere, ring your local number.

If you are having thoughts of harming yourself, please tell somebody who can be there. In the United States you can call or text 988. Wren will show you crisis numbers when it hears this, and it will not tell your family about it, because that conversation belongs to you.

The care circle can pass an alarm to the people watching over you when you tell Wren about a physical emergency. It is a message to your family, not a call for help. It depends on both phones having signal and on somebody looking at theirs. It never replaces ringing for help, and it must never be relied on in its place.

5. What the AI writes, and how much to trust it

Wren uses a large language model to hold a conversation with you, to sort what you say into a diary entry, to read a page you photograph, to notice patterns, and to write the summary for your doctor.

A language model can be wrong. It can misread. It can miss something. It can say a thing confidently that is simply not so. Wren is built with a great many guards against this, and the guards are not perfect and cannot be.

So:

• Check anything that matters. Above all, check anything about a medicine, a dose, a time, or a date, against the packet, the letter, or the person who wrote it.
• The doctor's letter is a starting point for a conversation with your clinician. It is not a clinical record, it is not a referral, and no clinician is obliged to act on it.
• When Wren reads a page you attached, nothing it finds goes into your diary or your medicines until you tap it yourself.
• Wren describes what it can see in a photograph of your body. It will not tell you what something is, whether it is serious, or whether it looks better than last time, and you must not take its silence as reassurance.
• Wren works offline. When it cannot reach the AI, it falls back to organising things on your phone. That is by design, and it means the quality of what you get can vary with your signal.

You are responsible for what you do with what Wren gives you.

6. Your licence to use Wren

We give you a personal, limited, non-exclusive, non-transferable, revocable licence to use one copy of Wren on Apple devices that you own or control, as permitted by the App Store Terms of Service. If you have a Wren Plus subscription, that licence includes the paid features for as long as the subscription is open.

That is a licence to use Wren, not a sale of it. We keep everything we own in it: the app, its design, its words, its prompts, its typefaces where we have licensed them, and the name Wren.

7. What you may not do

Please do not:

• Copy, sell, rent, lease, sub-license, or redistribute Wren.
• Take it apart. No reverse engineering, decompiling, or disassembling, except where the law says you may do so regardless of what a contract says.
• Get at our server, or anybody else's care circle, by any route other than the app itself.
• Run scripts, bots, or automated tools against Wren, or use it in a way designed to run up cost on our side.
• Try to work out somebody else's 3-word care circle code, or use one you were not given by the person it belongs to.
• Use Wren to break the law, to harass somebody, or to keep a record about a person who has not agreed to it.
• Present Wren's output as a medical opinion, a diagnosis, or a clinical record.
• Remove or hide any notice of ownership.

If you do any of this, we may end your access. See section 13.

8. Wren Plus

What stays free, forever

Nothing you need in order to be safe, or to be heard, is behind a price. The diary, logging a fall, your medicines and their reminders, the exercises, the games, the cognitive checks, reading the community, and voice and message banking are free for everybody, always. So is a real conversation with Wren every day.

The free side gets 12 messages to Wren a day and one call a week, and a free call runs up to six minutes. Your first seven days have no counting at all, which the app tells you at the start.

Wren Plus opens the doctor's letter over long periods, the long-term trends, the care circle alerts, and unlimited talking and calling. Paid use has a fair-use ceiling far above any real day (200 messages and 8 calls a day), so that one script cannot spend what a hundred honest subscribers bring in.

Watching over one person is free, and it always will be, because somebody keeping an eye on their mother should never find that it has lapsed. Watching over more than one is a Plus feature, up to 25 people, which is well above any real caseload.

The prices

Prices are in US dollars and are the prices at the time of writing. Apple shows you the real price, in your own currency, on the purchase screen before you buy, and that is the price that governs. Prices can change in future, and any change applies to renewals after we have told you.

One Wren Plus covers the whole care circle. If your daughter pays, your phone opens too, and the other way about. One plan, one circle.

The free trial

The 14 day free trial is offered on the yearly plan only, and only to somebody who has not taken one before. It is Apple's introductory free trial, run through the App Store.

At the end of the 14 days, the yearly subscription begins and your Apple account is charged $99.99, automatically, unless you cancel first. Wren tells you this before you start, and again as the trial is running out. If you do not want to be charged, cancel before the trial ends and you pay nothing. Any unused part of a free trial is forfeited when you buy a subscription.

Auto-renewal, in Apple's words and then in plain ones

Wren Plus yearly and monthly are auto-renewing subscriptions.

• Payment is charged to your Apple Account at confirmation of purchase.
• The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period.
• Your account is charged for renewal within 24 hours prior to the end of the current period, at the price of the plan you are on.
• You can manage the subscription, see when it renews, change the plan, or turn off auto-renewal in your Apple Account settings after purchase.
• Cancelling stops the next charge. It does not shorten the period you have already paid for, and Wren stays open until that period ends.

In plain words: it keeps going and keeps charging until you stop it, and you stop it yourself in your phone's settings. We are not allowed to do it for you and we cannot see your billing.

How to cancel

On your iPhone: Settings → your name at the top → Subscriptions → Wren → Cancel Subscription.

You can also do it inside the App Store app, from your account picture. Do it at least 24 hours before the renewal date.

Refunds

Apple sells Wren Plus, not us. Only Apple can give a refund, and we cannot. We have no ability to see your payment, reverse a charge, or issue store credit.

To ask for a refund, go to reportaproblem.apple.com and sign in with the Apple Account that made the purchase. Apple decides, under its own terms.

If somebody in your family has died, please write to us at hello@wrenapp.care. We cannot refund a purchase Apple took, but we will tell you exactly what to send Apple and we will do what we can to help you stop anything else.

Restoring what you paid for

A new phone, a reinstall, or a repair should not cost you what you bought. There is a "restore purchases" button in Wren, and it must never be hard to find. If it does not work, write to us.

Nothing is taken away

If a subscription lapses, everything you wrote is still there. The diary, the medicines, the entries, the recordings: all of it stays on your phone and stays yours. The paid features close. Your words never do.

9. The care circle, and what you are agreeing to

Read this part carefully, because it is the one place where health information about you goes to another person.

What the care circle is

The care circle has two roles. The keeper is the person the diary belongs to. The watcher is somebody they name, usually a daughter, a husband, a son. They are joined by a 3-word code such as brave-otter-4192. Either of them can make it: the keeper can create a code and hand it over, or a watcher can create one and ask the keeper to accept it. Nothing about the keeper is shared until the keeper accepts and turns sharing on, on their own screen, whichever way round it started.

Your consent, said plainly

When you turn sharing on as the keeper, you are agreeing that health information about you is sent from your phone, through our server, to the phone of a person you have named. You are agreeing to this for yourself. It is not implied by anything else in Wren, and nothing crosses until you switch it on, on your own screen, having seen what will be shared.

What the watcher sees

For a rolling fortnight, and only where you have left that category switched on:

• Whether you wrote anything each day. Not what you wrote.
• How many of the day's doses were ticked off, out of how many were due, and which one it was: the medicine's name, the time it is due, how much of it you take (for example "2 tablets, 100 mg"), which days it is taken on, what form it comes in, and whether it was ticked. A person standing at somebody else's pill box needs the amount, not only the name. Never the private note you wrote beside a medicine.
• The names of the symptoms you tapped, such as "tremor" or "trouble swallowing". The labels, not the sentences around them.
• How many falls or near-falls were logged.
• Short "worth a look" alerts built out of those counts: a fall, a run of missed doses, a quiet week, trouble swallowing, low mood.
• Low medicine warnings: the name of a medicine running out, and the day it runs to.
• Your first name and the condition you selected.
• Your cognitive check scores, as a first score, a latest score, and how many times you have sat it. This has its own switch on the sharing screen. It starts on, and you can turn it off there at any time. If you accept somebody's invitation with one tap, it is on, and the screen that asks you says so.
• An alarm, if you tell Wren about a physical emergency such as chest pain, a collapse, or choking. It carries a short note of what crossed and the time, never your words, and it fades from their screen after about three hours.
• Which categories you are sharing, so a blank never reads as "nothing happened" when it means "not shared".

What the watcher never sees

Never your diary text. Never your chat with Wren. Never a quotation of anything you said or typed. Not the entries, not the summaries, not the letter, not what you told Wren about yourself.

Also never: your videos, your voice recordings or voice memos, and anything read from Health.

About wanting to harm yourself. Your words are never sent to your circle, and Wren never raises the family alarm for it. The alarm is for physical emergencies, and it is deliberately not for this. Wren shows you, on your own screen, the people whose job it is to help.

What can still cross is a symptom label, in the same way any other symptom does. If Wren sorts that conversation as low mood, then "low mood" can appear among the day's symptoms and can raise a worth-a-look note, which is why "low mood" is in the list of alerts above. Never the words, never a quotation, never an alarm. If you would rather no symptom labels crossed at all, turn symptoms off on the sharing screen.

What the watcher can do back, if you allow it

You can grant a watcher the power to tick off a dose, add a medicine, or note a symptom for you. Every one of these is off unless you allow it. When noting a symptom, a watcher can also write one short sentence of their own, up to 140 characters, describing what they saw. When any of it arrives it is shown to you on your own medicines page with the watcher's name on it, and you can undo it. A watcher never holds the private identifiers of your diary or your medicines: they name things by their words.

The watcher's obligations

If you are the watcher, then by joining a circle you agree:

• To use what you see only to care for the person whose circle it is, and for nothing else. That holds whether they gave you the code or you made it and asked them to join.
• Not to pass it on. Not to an employer, not to an insurer, not to a landlord, not to a court, not to another family member the person has not included, and not onto social media.
• To respect that the person can change what you see or cut you off at any moment, without giving you a reason, and that this is their right and not a slight.
• To keep the 3-word code to yourself and to treat it as a secret.
• That you are not being given a monitoring service. Alerts can be late, can be missing, and depend on the other person's phone. Never treat silence from Wren as proof that somebody is all right, and never let Wren stand in for ringing them.
• To stop and leave the circle if you no longer have the person's agreement to be in it.

We do not vet watchers. We have no way to. Only give the code to somebody you trust with the fact of your illness.

The 3-word code is the credential

There is no account, no password, and no sign-in. The 3-word code is the whole of the credential. Anybody holding it can join the circle as a watcher and read the digest, and our server cannot tell one person from another, because it has never been told who anybody is.

The code is short on purpose, so that a person with a tremor can read it down a telephone to a person with a hearing aid. That is a real trade-off and you should know it is being made: a short code is a weaker secret than a long password. Treat it like a house key. Do not post it, do not put it in a public message, and do not give it to somebody you would not let read the fortnight.

If a code gets somewhere it should not, stop sharing. That deletes the box on the server and makes the old code useless. Then make a new one.

Revoking, at any time

You can stop at any moment, for any reason, without telling anybody why. In the app, "Stop sharing and delete it" turns sharing off and asks the server to delete all four boxes: the digest, the watchers' names, anything a watcher did back for you, and the Plus status. If one of those deletions does not go through, Wren tells you which. Leaving the circle does not delete anything from your diary. Your diary is yours and it stays.

You can also change what is shared without stopping altogether: turn off medicines, or symptoms, or falls, or writing, or checks. A category you turn off is not sent as a zero. It is not sent at all.

We cannot force a watcher to forget what they have already seen. Nobody can. Revoking stops anything further from crossing.

10. The community

Wren has a community area, so that people living with the same thing can find each other.

The community is switched off in this version of Wren. There is no community server, and nothing you write there is sent to us or to anybody else. Nothing in it is fabricated either: the feed is empty until there are real people in it, and there is not one invented person or invented post anywhere in it. The rules below apply from the moment it opens, and the reporting, blocking and 24-hour commitments take effect then.

There is no tolerance for objectionable content

By posting, commenting, messaging, or filling in a profile, you agree not to submit anything that is:

• Abusive, harassing, threatening, hateful, or aimed at somebody because of who they are.
• Obscene, sexually explicit, or violent.
• Fraudulent, spam, an advertisement, or a scheme to sell something.
• Medical advice given as though from a professional, a claimed cure, or anything urging a person to change or stop a prescribed treatment.
• Somebody else's private information, including another patient's health information, posted without their agreement.
• Somebody else's work, posted without the right to post it.
• Illegal in any other way.

We have zero tolerance for objectionable content and for abusive users. This is not a slogan. It is the rule we enforce.

Reporting, blocking, and what we do about it

• Report. When the community opens, every person and every piece of content will have a report control, and reporting will send it to us for review. Until then there is nothing posted to report, and the report control on a person's profile says as much rather than pretending to send something.
• Block. You can block another person. A blocked person's content stops reaching you.
• We act within 24 hours. Once the community is live, we will review reported content and remove anything objectionable, and eject the person who posted it, within 24 hours of the report.
• We may remove content or end access at any time, with or without a report, and without notice, if we believe these rules have been broken.
• Repeat or serious abuse ends the account permanently.

You can report abuse directly to hello@wrenapp.care at any time.

What you post stays yours

You keep ownership of everything you write. You give us permission to store it and display it inside Wren, so that the feature can work, and to remove it. We do not sell it, licence it out, or use it to advertise to anybody.

11. Your information

How Wren handles your information is set out in the Privacy Policy, at https://wrenapp.care/privacy, which forms part of these terms. The short version: your diary lives on your phone, there is no account, and the things that do leave are described there, one by one.

12. What we do not promise

Wren is provided "as is" and "as available", with all faults.

To the fullest extent the law allows, we disclaim every warranty, whether written, spoken, express or implied, including any implied warranty of merchantability, of satisfactory quality, of fitness for a particular purpose, of accuracy, and of non-infringement.

We do not promise that:

• Wren will be uninterrupted, timely, secure, or free of errors.
• What the AI produces will be accurate, complete, or suitable for anything.
• Reminders will arrive, or will arrive on time.
• A care circle alert or alarm will be delivered, or delivered promptly.
• Any defect will be corrected.

Some places do not allow the exclusion of implied warranties, so some of the above may not apply to you. Nothing here takes away a right you have under consumer law that cannot be waived, and if you are a consumer in the UK or the EU, your statutory rights stand whatever this section says.

13. Limits on what we owe you

To the fullest extent the law allows:

• We are not liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for lost profits, lost data, lost goodwill, or the cost of substitute services, whatever the theory and even if we were told such damage was possible.
• Our total liability to you, for everything, is limited to the greater of the amount you actually paid us for Wren in the 12 months before the claim, or fifty US dollars ($50).

This limit does not apply to anything a business cannot lawfully exclude: death or personal injury caused by our negligence, fraud, or fraudulent misrepresentation.

Because of what Wren is, please read this next part as well:

• We are not liable for a medical outcome. Not for a missed dose, a missed reminder, a symptom that was not recorded, an alert that did not arrive, a fall nobody was told about, or a decision made on the strength of something Wren wrote.
• We are not liable for what a member of your care circle does with what they see.
• We are not liable for what a third party service does. That includes Apple, Anthropic, our speech vendor, RevenueCat, Apple's push notification service, and your own phone's speech recognition.

Some places do not allow these limits, so some of the above may not apply to you.

14. What you cover us for

You agree to indemnify and hold harmless Sritej Padmanabhan and the people who work on Wren from any claim, loss, or cost, including reasonable legal fees, arising out of:

• Your use of Wren, or of what it produced.
• Anything you posted or sent through Wren.
• Your breach of these terms or of the law.
• Your sharing of another person's information through the care circle without their agreement, or your use of information about a person you were shown as a watcher.

15. Ending it

You can stop at any time. Delete the app. That removes everything Wren holds on your phone, including every voice recording. If you have a subscription, cancel it separately in your Apple settings first, because deleting the app does not cancel it.

We may suspend or end your access, with or without notice, if you break these terms, abuse another person, attack the service, or use Wren in a way that puts somebody at risk. Where we can give notice first, we will.

Sections 3, 4, 5, 12, 13, 14, 16 and 17 survive the end of this agreement.

16. If Wren shuts down

Nobody likes writing this section, and an app that holds a person's diary owes them an answer to it.

Your diary is on your phone, not on our server, so if Wren stopped tomorrow, everything you wrote would still be on your phone. So would every recording under "Your voice", every photograph, every video and every voice memo. They do not depend on us being alive, and they can be exported and shared with your phone's own tools without us.

What would stop is the part that needs a server: the AI conversation, the doctor's letter, the reading of a page, Wren's spoken voice, and the care circle. Wren keeps working offline for the diary itself, so the app would keep taking down what you say, organised on the phone.

If we ever decide to shut Wren down, we will:

• Say so in the app and on https://wrenapp.care at least 60 days before, where we possibly can.
• Turn off all new charges immediately and cancel any renewals we are able to.
• Tell you plainly how to get your diary out and where it already is.
• Delete the care circle boxes from our server.

If Wren is sold or transferred to somebody else, the same promises in this document and in the Privacy Policy travel with it, and we will say so in the app before anything changes.

17. Law, and how disagreements are settled

These terms are governed by the laws of the Commonwealth of Pennsylvania, United States, without regard to its conflict of law rules. You and we agree to the exclusive jurisdiction of the courts of the Commonwealth of Pennsylvania, United States for any dispute, except that either of us may seek an injunction anywhere it is needed to protect intellectual property.

If you are a consumer resident in the United Kingdom, the European Union, or another place whose law gives you the right to bring a claim in your own local courts and under your own local law, that right is untouched by this section.

Please write to us first. Most things can be sorted out by an email to hello@wrenapp.care, and we would much rather answer you than argue with you.

If any part of these terms is found unenforceable, the rest carries on. If we do not enforce something straight away, we have not given up the right to enforce it later.

These terms, with the Privacy Policy, are the whole agreement between you and us about Wren.

18. Apple

Wren is downloaded from Apple's App Store, and Apple requires the following to be part of this agreement. It is written in the way Apple requires it. Plain-English notes are in brackets.

1. This agreement is between you and us, not between you and Apple. Apple is not a party to it. We alone are responsible for Wren and its contents.

2. The licence granted to you in section 6 is a licence to use Wren on any Apple-branded device that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, except that Wren may be accessed by other accounts associated with you through Family Sharing or volume purchasing.

3. Apple has no obligation whatsoever to provide any maintenance or support for Wren. (If you need help, write to hello@wrenapp.care. Do not ask Apple.)

4. If Wren fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the app to you. To the maximum extent permitted by law, Apple has no other warranty obligation whatsoever with respect to Wren, and any other claims, losses, liabilities, damages, costs or expenses attributable to a failure to conform to any warranty are our responsibility alone.

5. We, not Apple, are responsible for addressing any claims by you or any third party relating to Wren or your possession and use of it, including product liability claims, any claim that Wren fails to conform to any applicable legal or regulatory requirement, and claims arising under consumer protection, privacy, or similar legislation, including in connection with Wren's use of the HealthKit framework.

6. If a third party claims that Wren, or your possession and use of it, infringes that third party's intellectual property rights, we, not Apple, are solely responsible for the investigation, defence, settlement and discharge of that claim.

7. You represent and warrant that you are not located in a country that is subject to a US Government embargo, or that has been designated by the US Government as a "terrorist supporting" country, and that you are not listed on any US Government list of prohibited or restricted parties.

8. Apple and Apple's subsidiaries are third-party beneficiaries of this agreement, and upon your acceptance of it, Apple will have the right (and will be deemed to have accepted the right) to enforce it against you as a third-party beneficiary.

9. You must comply with any applicable third-party terms of service when using Wren.

19. Changes to these terms

If we change these terms, we will update the date at the top and describe the change in the app's release notes. If a change is a significant one, we will say so in the app itself before it takes effect. Carrying on using Wren after a change means you accept it. If you do not accept it, stop using Wren and cancel any subscription.

20. Contact

Write to us. A person reads it.

hello@wrenapp.care https://wrenapp.care

If your question is about a payment, a refund, or a subscription, Apple holds that, and reportaproblem.apple.com is the fastest route. We will still help you find your way there.
