Privacy Policy
Last updated: 25 October 2026
CataPred is an eye-screening app made by Happy Health Innovations Pvt Ltd ("we", "us"). This page explains what information the app collects, why, who can see it, and how you can delete it. If anything here is unclear, email info@happyhealthinnovations.in.
What we collect
| Information | Why we need it |
|---|---|
| Your phone number | To sign you in with a one-time SMS code, and to identify your account. |
| Name, age, gender | To set up your profile and show it on your results. |
| Email, pincode, referral code (optional) | Only if you choose to add them to your profile. |
| Photos of your eyes | Taken during the AI cataract screening, sent to our server for analysis, and stored with that result. |
| Your test answers and results | From each of the vision tests, so you can see your results and history. |
| Clinic details (clinics only) | If you register a clinic: its name, type, address and contact details, so CataPred can review and approve it. |
| Crash reports and device information | Collected automatically when the app crashes, so we can fix the problem, and to confirm requests come from the real CataPred app. |
We do not collect your location (your pincode is only what you type), your contacts, payment details, or an advertising ID. There are no ads in CataPred, and we do not sell your information to anyone.
How some features work
- Voice answers. In the vision acuity test you can say your answers out loud. This uses your phone's built-in speech recognition (provided by Google on Android and Apple on iPhone, under their own privacy terms). CataPred does not record or store any audio.
- Distance check. Before some tests, the camera checks how far your face is from the screen. This happens entirely on your phone; those camera images are never saved or uploaded.
- AI cataract screening. The two eye photos are uploaded to our server, analysed by our AI model, and stored with your result.
Who can see your information
- You can see your profile, credits and all your results in the app.
- Clinics that test you. If a clinic, hospital or eye camp runs a test on you through CataPred, that clinic's staff can see the result. Approved clinic staff can also look up a patient by phone number to start a test, which shows that person's name, age and gender.
- Our team, only to run the service, help with support requests, and fix problems.
- Google Cloud / Firebase stores and processes our data on our behalf (database, file storage, sign-in, and crash reports). They do not use it for their own purposes.
- Authorities, only if the law requires us to share it.
Where it's stored and how it's protected
Your information is stored with Google Cloud. Test results are kept in India (Mumbai); account and profile information is kept in the United States. Data is encrypted while travelling between the app and our servers, and access rules ensure people can only reach the information they're allowed to see.
How long we keep it
We keep your information until you delete your account. Crash reports are kept for about 90 days. If a clinic ran a test on you, that clinic's own record of the test stays with the clinic after you delete your account, as it forms part of their records.
Your choices and rights
Under India's Digital Personal Data Protection Act, 2023, you can:
- See your information: it's all in the app (Profile and History).
- Correct it: edit your Profile at any time.
- Delete it: in the app, open the side menu and tap Delete Account, or follow these steps if you no longer have the app. Deleting your account removes your profile, credits, login, test results and eye photos.
- Withdraw consent: deleting your account stops all further use of your information.
- Raise a concern: email us at info@happyhealthinnovations.in. We reply within 30 days. If you're not satisfied, you can complain to the Data Protection Board of India.
Children
CataPred can be used to screen a child's eyes. If the person being tested is under 18, a parent or guardian must create the account or give consent, and should be present during the test.
A note about medical use
CataPred is a screening tool for awareness. It is not a medical diagnosis and does not replace an examination by a qualified eye doctor. Please see an eye doctor about any result that worries you, or any change in your vision.
Changes to this policy
If we change this policy, we'll update it here and change the date at the top.
