The agreement, in plain English.

These terms are the agreement between you and Kinsu Health for using the Kinsu Health app for Android and the website at kinsu.health. They apply whenever you use the app or the website, so please read them first. If something here is unclear, that's our failure: email us and we'll explain.

Last updated: 6 October 2026 · Applies to Kinsu Health for Android (com.kinsu.health) and kinsu.health

1. Who you're dealing with

Kinsu Health, India ("Kinsu", "we", "us") makes the Kinsu Health app for Android (com.kinsu.health) and runs the website at kinsu.health. "You" means the person using the app or the website.

2. What Kinsu is and isn't

What the app does

Medicine reminders at the times you set, around your meals or at a time of your own.
Readings and logs: blood pressure, blood sugar, weight, pulse, SpO2 and temperature, plus sleep, mood, symptoms, diet, exercise and illness episodes.
A records vault for prescriptions, lab reports, scans and discharge summaries. You can keep records for family members too, labelled with whose they are, on your phone (section 4).
SOS and Medical ID: your name, blood group and health goals, public emergency numbers, and your own emergency contacts.
Care routines for hair, skin and eye care, with reminders and general tips.
Export: save the categories of records you choose as files on your phone.

Charts and summaries in the app are calculated from what you enter. If an entry is wrong, they will be too. Kinsu does not check whether a medicine, dose or schedule is right for you. It reminds you of what you entered.

What it isn't

Kinsu Health is not a medical device and does not diagnose, treat, cure or prevent any medical condition. Always consult a doctor or other qualified healthcare professional for medical advice, diagnosis or treatment.

Kinsu does not replace your doctor, your pharmacist or your prescription. Follow your doctor's instructions about your medicines.

In an emergency, call 112. The SOS screen only opens your phone's dialler with the number ready, and you still have to press call. Kinsu does not call, message or alert anyone for you, and does not share your location.

3. Your account

Adults only. You must be 18 or older to use Kinsu. The app asks for your date of birth and will not set up for anyone under 18. That age is declared, not verified, so please be truthful.
Your mobile number. You sign in with an Indian mobile number, verified by a one-time code sent by SMS. Use a number that is yours.
Your phone and its screen lock. Kinsu is protected by your phone's fingerprint, face or screen lock, and will not set up on a phone without a screen lock. Anyone who can get past your phone's lock may be able to open Kinsu, so keep your phone and its PIN, pattern or password to yourself.
Your 12-word recovery code. You get it during setup. It is the only way back into your records on your phone if the phone's security settings change. We don't have a copy and cannot reset it. Write it down, keep it safe, and don't share it.
What you enter. You are responsible for what you put into Kinsu and for checking that it is correct. Kinsu does not verify medical content.

4. Records you keep for other people

Kinsu lets you add family members and keep their records, such as a parent's prescriptions or a child's lab reports, labelled with whose they are.

Only keep records for someone who has agreed to it, or for whom you have lawful authority: for example, your child, or a person whose legal guardian you are. This applies to anything you enter about another person.
Their records stay on your phone, like your own. Kinsu does not send them to that person, to us or to anyone else.
The person does not get access to their records through Kinsu. Kinsu has no feature that lets anyone else see your records.
Adding someone as an emergency contact on the SOS screen lets you call them from there. It does not give them access to anything.
If a person withdraws their agreement, delete the records you keep for them.

5. Your data

Your health data is yours. In short:

Your records are stored on your phone, encrypted. We cannot read them, and we never receive them.
Of what you keep in Kinsu, only two things leave your phone: your mobile number, sent to Google Firebase so it can be verified, and an encrypted copy of your recovery key, stored in Google Cloud Firestore in Mumbai. That key copy is useless without your 12-word code. Signing in also sends Firebase the technical data described in section 4 of the Privacy Policy.
We run no analytics, show no ads, and sell nothing to anyone.

The full details are in the Privacy Policy, which forms part of these terms. If the two ever seem to differ about how your data is handled, the Privacy Policy applies.

There is no backup

Kinsu keeps no copy of your records anywhere else. There is no cloud backup, and Android's own backup of the app is switched off. That keeps your records private, but it means:

If your phone is lost, stolen, broken or reset, or you uninstall Kinsu, you lose the records on it. Neither you nor we can recover them from anywhere else.
Your recovery code gets you back into your records on the same phone if its security settings change. It does not move records to a new phone.
If you lose your recovery code and your phone's security settings then change, you will not be able to open your records again. There is no master key.

Copies you take out

Exports (CSV and JSON files) and documents you save are written to your phone's Downloads folder without encryption, so that you and other apps can open them. Once a file leaves Kinsu, keeping it safe is up to you. An export is a copy for you to read and keep. Kinsu cannot restore records from it.

6. What you can and can't do

You can

Use Kinsu for your own health records and your family's, for personal, non-commercial purposes.
Export your data whenever you want.
Delete your account at any time (section 11).

You can't

Keep records about anyone without their agreement or your lawful authority (section 4).
Sign in with a mobile number that isn't yours, or pretend to be someone else.
Use Kinsu as a records system for patients or customers, for example in a clinic, hospital, pharmacy or lab. It isn't built for that.
Copy, modify, reverse-engineer or decompile the app, except where Indian law expressly allows it.
Try to get around the app's security, its lock or its sign-in checks, or interfere with the services it relies on, for example by sending automated sign-in requests.
Put unlawful content into Kinsu, or content that infringes someone else's rights.
Use Kinsu or our website to harass, mislead or harm anyone.
Add someone else's email address to our waitlist without their permission.

7. Fees

Kinsu Health is free to download. If we ever offer paid features, we will say clearly what they cost before anyone pays, and update these terms. Nothing is charged without your explicit consent.

Your mobile operator's usual data charges still apply.

8. Intellectual property

The Kinsu Health app, the Kinsu name and logo, and the website belong to Kinsu Health. We give you a personal, limited, non-exclusive, non-transferable and revocable licence to install the app on your own phone and use it, and to use the website, for their intended purpose.

Some parts of the app are open-source software, used under their own licences.

You keep ownership of everything you add to Kinsu. These terms give us no rights to it, and we never receive it. If you send us feedback or suggestions, we may use them to improve Kinsu without owing you anything for them.

9. Third-party services

Kinsu relies on a few services run by other companies. Their own terms apply to your use of them.

Google Play (Google LLC) is how the app is distributed. Your Google Play account, and what you download from it, are covered by Google's terms.
Google Firebase (Google LLC) verifies your mobile number when you sign in, and stores the encrypted copy of your recovery key. Google processes this data on our behalf.
FormSubmit delivers your email address to us if you join the waitlist on our website.

What Google Firebase receives, and where, is set out in section 4 of the Privacy Policy, and how the waitlist works in section 13. Apart from these, Kinsu sends nothing you enter in the app to any other company.

When you use SOS, Help or Export, save a document or copy a doctor summary, Kinsu hands over to your phone's own dialler, email app, files or clipboard. What happens after that is up to you and those apps.

10. Availability and changes

We work to keep Kinsu running well, but we cannot promise that it will always be available, free of errors or uninterrupted.

Internet. Setting up Kinsu, signing in again after you sign out, and deleting your account need an internet connection, because each uses a code sent by SMS. Otherwise the app works without one.
Reminders. Reminders are scheduled on your phone as notifications. Whether they arrive depends on your phone: its notification permission, its battery-saving and do-not-disturb settings, and its clock and time zone. Some phones stop notifications from apps they put to sleep. So we cannot guarantee that every reminder arrives, or arrives on time. If missing a dose could be serious, don't rely on Kinsu alone.
Changes to the app. We may update, add or remove features. If a change takes away something important, we will tell you in the app first where we can, so you have time to export your records.

11. Ending your use

You can leave at any time

In the app: Settings → Delete account. Kinsu checks your number with a fresh code, then deletes your account, the encrypted key copy, and everything Kinsu keeps on your phone: records, documents, reminders and the keys that protect them. This cannot be undone, so export anything you want to keep first.
Without the app: follow the steps at kinsu.health/delete-account.

Uninstalling Kinsu deletes everything Kinsu keeps on your phone, but not your account. To delete that too, use one of the two ways above.

Files you exported or saved to your Downloads folder are outside Kinsu. Deleting your account or uninstalling the app does not remove them, so delete them yourself if you no longer want them.

When we can end it

We may suspend or close your account if you seriously or repeatedly break these terms, if you use Kinsu to harm others, or if the law requires it. Where we can, we will tell you first and give you a chance to respond.

Sections 8, 12, 13, 14 and 16 continue to apply after your use ends.

12. Disclaimers

Kinsu is provided "as is" and "as available". To the maximum extent Indian law allows, we make no promises beyond those in these terms, and we disclaim all implied warranties, including fitness for a particular medical purpose, merchantability and non-infringement.

Nothing in Kinsu is medical advice. That includes reminders, charts, summaries and care-routine tips. Don't start, stop or change a medicine or treatment because of something in Kinsu. Ask your doctor.

13. Limitation of liability

To the maximum extent Indian law allows, Kinsu Health is not liable for indirect, incidental, special or consequential damages arising from your use of the app or the website. We are also not responsible for loss caused by things outside our control, such as a lost or reset phone, a lost recovery code, a reminder your phone did not deliver, or an outage at a service we rely on.

Our total liability for any claim related to Kinsu is limited to the greater of (a) the amount you paid us in the 12 months before the claim, or (b) ₹10,000.

Nothing in this section limits any liability that cannot be limited under Indian law: for example, liability for gross negligence, wilful misconduct, or a statutory right you have as a consumer.

14. Indemnity

If someone makes a claim against Kinsu Health because you misused Kinsu, broke these terms, or violated another person's rights, including by keeping records about someone without their agreement or lawful authority, you agree to indemnify Kinsu Health. That means covering the losses and reasonable costs that result.

15. Grievance redressal

If you have a complaint about Kinsu, write to our Grievance Officer.

Grievance Officer: reached at kinsu.health@gmail.com
Response: we acknowledge within 7 days and resolve within one month.

For complaints about your personal data, see sections 10 and 14 of the Privacy Policy. If we do not resolve your complaint, you may take it to the Data Protection Board of India once it is operating.

16. Governing law and jurisdiction

These terms are governed by the laws of India. Any dispute arising out of or in connection with them falls under the exclusive jurisdiction of the courts at Bengaluru, Karnataka, India.

17. Changes to these terms

If we change these terms materially, we will post the new version here, with its date, before it takes effect, and tell you in the app where we can. The latest version is always at kinsu.health/terms, with its date at the top.

If you don't agree with a change, you can stop using Kinsu and delete your account before it takes effect. If you keep using Kinsu after that, the new terms apply.

18. Contact

We wrote these to be read, not to trap you. If a clause seems unfair or unclear, or doesn't match what the app does, tell us and we'll fix it.
