1. Information We Collect

1.1 Data Stored on Your Device

The app stores the following information in its private storage on your device:

• Daily water intake goal and glass size
• Drink history: which drink, its volume and the time you logged it
• Your drinks and their composition (hydration coefficient, caffeine, sugar, calories)
• Data used to calculate your goal (weight, activity level, climate)
• Reminder and app settings
• If you connect backup: the email address of your Yandex account and the access token for Yandex Disk

We have no servers that store this data. Parts of it leave your device only in the cases described in sections 1.2–1.4.

1.2 Analytics Data (AppMetrica)

We use AppMetrica, a mobile analytics SDK provided by Yandex, to monitor app stability and understand how the app is used. AppMetrica may automatically collect device information (model, OS version, and identifiers such as the advertising ID), your IP address, and usage data such as sessions, crashes, and actions in the app, including some values you enter (for example, weight when calculating your goal, and the type and volume of drinks). This data is processed by Yandex in accordance with the AppMetrica / Yandex Privacy Policy.

1.3 Health Connect

Health Connect is an Android service that stores health and fitness data on your device and lets you share it between apps. Sharing your drinks with Health Connect is off by default. You can turn it on in Settings → Integrations; Android will then ask you to grant the permission.

• Data type: the app requests one permission only, to write Hydration. It does not read any data from Health Connect.
• What is written: the time and volume of each drink you log, with the volume adjusted by the drink's hydration coefficient. When you turn the feature on, the last 7 days are written; after that, adding, editing or deleting an entry updates that day in Health Connect.
• How it is used: only so that you can see your water intake in other health and fitness apps. Other apps can read this data only if you allow them to in Health Connect.
• Sharing: data you share with Health Connect stays on your device. It is not sent to us or to any third party, is not used for advertising and is not sold.

1.4 Yandex Disk Backup

Backup is optional and works only after you connect your Yandex account. The app gets access only to its own folder on your Yandex Disk (Applications) and to your account email, which is shown in the app so you know which account is connected. A backup file contains your drink history, drinks, goal, data for its calculation and app settings. Files are stored in your Yandex Disk account; we have no access to them. Backup files are compressed and obfuscated, but not encrypted, so keep your Yandex account secure. Yandex processes this data under the Yandex Privacy Policy.

2. How We Use Information

Data on your device (section 1.1) is used to provide the app's features: tracking what you drink, calculating your daily goal, statistics and reminders.

Analytics data (section 1.2) is used to understand how the app is used, fix bugs and crashes, and improve the app's features. We do not use this data to identify individual users, and we do not sell it.

Health Connect (section 1.3) and backup (section 1.4) are used only for the purpose you turned them on for.

3. Data Storage, Transfer and Security

• App data is kept in the app's private storage, which other apps cannot access.
• All network connections (AppMetrica, Yandex ID, Yandex Disk) use encrypted HTTPS (TLS).
• Health Connect data is stored on your device and protected by Android.
• The app does not show ads, and we do not sell or transfer your data for advertising.

5. Managing and Deleting Your Data

• Uninstalling the app, or clearing its data in your device settings, permanently deletes all data stored on your device.
• Health Connect: turn it off in Settings → Integrations, or revoke the permission in Health Connect. Data already written stays in Health Connect; you can view and delete it in the Health Connect settings (hydration data).
