The short version: Nitor doesn’t collect your data. The camera is processed entirely on your phone and no video or image ever leaves your device. There are no accounts, no servers, and nobody watching.
Who is responsible
Nitor Fit is a mobile app developed by IMPULSOTEK, based in Spain. It comes in an iPhone version and an Android version. For any privacy question you can write to soporte@nitorfit.es
What data Nitor collects
None. Nitor has no account system and no sign-up. It doesn’t ask for your name, your email, your location or any other personal data. We don’t use our own servers: there is no database of Nitor users. This is the same on iPhone and on Android.
The camera
Nitor uses your phone’s camera for one purpose only: counting your exercise repetitions through body pose detection.
- All processing happens on your device. On iPhone it uses Apple’s Vision framework; on Android, Google’s MediaPipe library. Both work offline and send nothing off the phone.
- No video or image is recorded, stored or sent anywhere. Frames are analysed in real time and discarded immediately.
- The camera is only active while you have the rep-counting screen open, and you can revoke the permission whenever you like from your phone’s settings.
The apps you choose to block
iPhone and Android work differently here, and we would rather tell you plainly than hide it.
On iPhone
To block the apps you choose, Nitor uses Apple’s official tools (Screen Time / Family Controls). Here’s how that works:
- Your app selection is handled through opaque system identifiers: Nitor cannot see or know which apps you pick; only iOS knows.
- That configuration is stored on your device only.
On Android
Android has no equivalent to Apple’s system, so the blocking is held up by the app itself. That changes one thing, and we’ll say it without dressing it up: on Android, Nitor does see which apps you choose to block and which one you have open at any moment. That is what lets it block them again when your minutes run out.
- To know which app is in front, Nitor uses the Usage access permission, which you grant by hand in Android’s settings and can withdraw whenever you like.
- That information never leaves your phone. It is not sent to any server, not stored anywhere outside your device and not shared with anyone. We still have no servers and no database of users.
- Nitor does not use Android’s accessibility service or device administrator mode, the two routes other apps use to obtain far broader control of your phone.
- Nitor does not query your full list of installed apps either: it only sees the ones that appear in your app drawer, which are the ones it needs to show you the picker.
- If you uninstall the app, all of it goes with it.
Your steps
If you want it to, Nitor counts your steps and turns them into minutes: every 1,000 steps is 2 minutes, with no daily limit. It is optional; the app works just the same without it.
- The steps are counted by the phone’s own sensor, not by Nitor. On iPhone this needs the Motion & Fitness permission, and on Android the Physical activity permission. You grant them and can withdraw them at any time from your phone’s settings.
- That count never leaves your phone. It is not sent to any server, not shared with anyone and not tied to any identity, because Nitor has no accounts.
- On iPhone, if you allow it, Nitor reads only your step count from Apple Health, so the steps your Apple Watch counts are added too. It only reads them: it writes nothing to Health, reads no other health data, and that number never leaves your iPhone and is never used for advertising. You can withdraw the permission at any time in Settings → Health → Data Access & Devices → Nitor. On Android, if you give permission, Nitor reads only your step count from Health Connect, to add the steps counted by your watch too (for example, through Samsung Health, Fitbit or Google Fit). It only reads them: it writes nothing to Health Connect, reads no other health data, and that number never leaves your phone or is used for advertising; Nitor doesn’t even have internet permission. Nitor’s use of information received from Health Connect adheres to the Health Connect Permissions policy, including the Limited Use requirements. You can withdraw the permission at any time in Settings → Health Connect → App permissions → Nitor Fit.
- Steps and repetitions are a way of earning screen time, not a diagnosis or medical advice. Nitor does not measure vital signs and does not replace any healthcare professional.
- If you uninstall the app, that count goes with it.
Your progress
Your accumulated movement, your streaks and your creature’s state are stored locally on your phone. If you delete the app, that data is deleted with it.
Third-party services
Nitor includes no advertising SDKs, no third-party analytics and no trackers, on iPhone or on Android. Apple and Google, as the operators of their stores, may provide us with aggregated and anonymous download and usage statistics (subject to your own device’s privacy settings, which you control). Those statistics cannot identify you.
Children
Nitor collects no data from anyone, children included. The app is intended for adults.
Your rights
Since we don’t collect personal data, there is no data of yours to access, correct or delete in our systems. Even so, if you have any privacy question, write to soporte@nitorfit.es and we’ll answer. You also have the right to lodge a complaint with the Spanish Data Protection Agency (aepd.es).
Changes to this policy
If Nitor ever changes and starts processing some kind of data (for example when adding new features), we will update this page beforehand and tell you clearly inside the app. The last updated date always appears at the top.
