Trosana privacy policy
Effective date: [date of publication] Who we are: Trosana is published by [legal owner or business name], [city, country]. Contact: hello@trosana.app.
In short
- No account, no sign-in, no ads, and no tracking or analytics of our own.
- Your health profile stays on your phone. Conditions, medicines, allergies and the rest are stored only on your device. They are excluded from cloud backup and device-to-device transfer, and never sent to us.
- Label photos never leave your phone. They are read on the device and deleted straight away.
- A few Google services the app relies on, and our content server, receive limited technical information, as described below.
1. Information stored only on your phone
When you use Trosana you can enter:
- health conditions, medicines and life stage (for example pregnancy), and food allergies;
- your name (optional, only for greetings), age group, sex, region and diet;
- answers to the "Foods for you" questions and the interests you pick;
- settings (theme, notifications) and the foods you opened recently.
This information is used only on your phone: to show warnings, personalise the order of foods, recipes and research, and to pick your weekly food. It is not sent to us or anyone else, it is excluded from Android cloud backup and device transfer, and it is deleted when you clear the app's data or uninstall the app. You can change or remove it at any time in Profile.
2. Photos of food labels
"Check a packaged food" uses your phone's camera app (Trosana has no camera permission) or a photo you pick. The photo is saved temporarily in the app's private storage, its text is read on your phone by Google's ML Kit text recognition, and the photo is then deleted. The photo and its text are never uploaded.
3. Services that receive technical information
| Service | What it receives | Why |
|---|---|---|
| Google ML Kit (text recognition, via Google Play services) | Device information (manufacturer, model, Android version), app package name and version, a per-installation identifier, performance metrics, feature settings and error codes. Not the photo or its text. Encrypted in transit; Google states it does not share this data with third parties. | Diagnostics and usage analytics by Google. See Google's ML Kit data disclosure and the Google Privacy Policy. |
| Google Play (app download, updates, and Google Play Billing for tips and subscriptions) | What Google Play normally processes for app installs and purchases, under Google's terms. We do not receive your card or payment details. | Installing the app, payments. |
| Our content server (the static file host we use for updates (named here once content updates are switched on)) | The app downloads signed content updates (new research, recipes and food rules). Requests contain no personal or health information; like any web server, the host receives your IP address, the time and the app's version in standard request logs. | Keeping the app's information up to date. |
4. Notifications
The weekly food tip and "new research & recipes" alerts are worked out on your phone. Nothing about you is sent anywhere to produce them. Turn them off in Profile or in Android settings.
5. If you email us
If you use "Send feedback" or write to hello@trosana.app, we receive your email address and whatever you write. The feedback email is pre-filled only with the app version and phone model, which you can delete before sending. We use emails only to reply and to improve the app, keep them no longer than needed, and delete them on request. Please don't send health details you'd rather keep private.
6. Children
Trosana is meant for adults. Anyone under 18 should use it with a parent or guardian (see the Terms of use). We do not knowingly collect personal information from children.
7. Your choices and rights
Because your profile stays on your phone, you control it directly: edit it in Profile, or remove it by clearing the app's data or uninstalling. For emails you have sent us, contact hello@trosana.app to access or delete them. Depending on where you live (for example under India's Digital Personal Data Protection Act, 2023, or the EU GDPR), you may have further rights; contact us to use them.
8. Security
Content updates are downloaded over HTTPS and checked against our digital signature before use. Your profile is kept in the app's private storage, which other apps cannot read.
9. Changes
If this policy changes, we will update the effective date and, for significant changes, tell you in the app's "What's new".
