Hydrora (“the app”) is a water tracker and drink reminder: it helps you log what you drink, set a daily goal and receive optional reminders. It is published by AppVita Studio. This policy explains what data the app handles and why.
Everything you enter in Hydrora - the drinks you log (type, amount, time), your daily goal, your custom drinks and glasses, your reminder schedule, milestones and settings (language, unit, theme) - is stored only on your device, in the app’s private storage.
We do not collect it, we do not transmit it, we do not share it and we have no servers that receive it. There is no account and no registration, so there is no account to delete.
The app does not ask for your weight, age, sex or any health condition. The optional goal estimate only uses the choices you make on screen (reference amount, activity, climate) and is computed on the device.
The app does not request access to your location, contacts, camera, microphone or files. Hydrora is not a medical device and does not provide medical advice.
If you turn reminders on, the app asks Android for permission to show notifications. Reminders are scheduled locally on your phone; no push service or server is involved.
The home-screen widget reads today’s progress from the app’s private storage on your device. Drinks logged from the widget are saved on the device and added to your history the next time the app opens.
You can export your entries (CSV) or a full backup (JSON) from Settings. The file is created on your device and handed to the Android share menu: you choose where it goes (for example your own cloud drive or e-mail). Hydrora never uploads it anywhere by itself.
You can delete all your data at any time from Settings > Your data > Delete all data, by clearing the app data in the Android settings, or by uninstalling the app.
Hydrora is free and is supported by a small banner provided by Google AdMob. The banner is shown only after the first setup, and the app never shows full-screen ads.
To serve ads, Google may collect and process:
This processing is carried out by Google as an independent data controller, according to its own policies:
Your drinks, goals and settings are never shared with the advertising network.
If you are in the European Economic Area, the United Kingdom or Switzerland, the app shows you a consent form from Google’s User Messaging Platform (UMP) before any ad is loaded. You choose whether to allow personalised advertising.
If consent is not given, no ads are requested at all.
You can change or withdraw your choice at any time with the Ad privacy choices item in the app’s Settings (shown when required in your region).
The app is not directed to children under 13.
Since your data never leaves your device, you are in full control of it:
If this policy changes, the “last updated” date at the top of this page changes with it, and the new version is published at this same address.
