This Privacy Policy explains how Fitness Band – Health Tracker ("the App", "we", "us", or "our") collects, uses, stores, and discloses your personal information and health and fitness data.
Introduction
Fitness Band – Health Tracker is an app designed to help you sync, view, and manage your health and fitness information.
The App integrates with the Google Health API to access authorized health and fitness information, including activity, heart rate, weight, height, sleep, hydration, measurement settings, and age.
On Android devices, the App also supports Health Connect to write selected fitness data, including DistanceRecord, HeartRateRecord, and StepsRecord, to Health Connect when you grant the required permissions.
We only access health and fitness data after you grant the required permissions. The specific information accessed depends on the permissions you authorize and the features you choose to use.
What Information We Collect
Google Health Data
When you connect your Google Health account, Fitness Band – Health Tracker may access the following categories of health and fitness data that you authorize:
- Activity and fitness data: steps and distance.
- Health metrics and measurements: heart rate, weight, and height.
- Sleep data: sleep stages and sleep duration.
- Nutrition data: water and hydration intake only. The App does not access food or meal data.
- Settings: measurement units used for distance, height, weight, and water.
- Profile information: age, used to provide age-related fitness information and features.
Where supported by the applicable Google Health API permissions, the App may also write certain information to Google Health:

Google Health Data Processing
Fitness Band – Health Tracker is a native Android application and does not operate a backend server or developer-controlled database for Google Health data.
Google Health data accessed by the App is processed locally on your device to provide the App's user-facing health and fitness features.
API responses containing Google Health data are held in application memory for rendering and processing and are not persisted in the App's local database.
Google Health data is not uploaded to our servers, analytics services, advertising SDKs, data brokers, or other third-party services.
When you choose to record information such as weight or water intake, the App sends that information directly from your device to Google through the applicable Google Health API.
The App does not transmit Google Health data to our own servers.
Improve App Functionality
The App may use app-local information, such as water reminders and portion presets, to provide and improve the related features.
We do not use Google Health or Health Connect health and fitness data for advertising, personalized advertising, marketing, or unrelated data mining purposes.

Google OpenID Connect
Google OpenID Connect is used separately from the Google Health API to obtain basic profile information after Google sign-in.
The App uses the Google Identity Services authorization flow to obtain the information needed to display:
- Display name
- Profile picture
The App does not use Google OpenID Connect profile information for advertising or unrelated purposes.
Health Connect Permissions – Android Only
On Android devices, the App may write selected fitness records, including DistanceRecord, HeartRateRecord, and StepsRecord, to Health Connect when you grant the corresponding permissions.
The App only writes these records to Health Connect when the corresponding permission has been granted and the feature requires it.
The App does not read or retrieve health or fitness data from Health Connect.
OAuth Tokens and Authorization
Fitness Band – Health Tracker uses the Google Identity Services Authorization API through the Google Play services authentication library for client-side authorization.
The App does not use offline access and does not request or store Google OAuth refresh tokens.
The App uses short-lived Google OAuth access tokens for online access to the Google Health API. Access tokens are temporarily stored in the App's private SharedPreferences storage.
The access token is protected by the Android application sandbox and the platform's file-based encryption at rest. The token is not additionally encrypted at the application layer.
Access tokens are used only to make authorized requests to Google services. They are not transmitted to our own servers or to unrelated third-party services.
When an access token expires or is rejected, the App requests authorization again through the Google authorization flow.
The App does not store a Google OAuth client secret because it does not have a backend server component.
When you sign out, the App revokes the Google OAuth authorization grant through Google's OAuth revocation endpoint.
Data Storage and Retention
Fitness Band – Health Tracker does not operate a backend server or developer-controlled database for Google Health data.
Google Health data accessed by the App is not persisted in the App's local database. API responses are held in application memory only for rendering and providing the relevant App features.
Google Health data is therefore not retained by Fitness Band – Health Tracker after the relevant in-memory processing ends.
Google OAuth access tokens are temporarily stored in the App's private SharedPreferences storage and remain there until they expire, are rejected, or are cleared through the applicable authorization or sign-out flow.
No Google OAuth refresh tokens are stored.
The App's local database is limited to app-local information such as water reminders and water portion presets. It does not store Google Health API responses.
Fitness data written by the App to Health Connect is managed through Health Connect on your Android device.
App-local information remains on your device until it is deleted through the applicable App functionality or the App is uninstalled.
Data Deletion
Fitness Band – Health Tracker does not independently store Google Health health and fitness records on our servers. Therefore, deletion of Google Health health records from our systems is generally not applicable.
Google Health data accessed by the App is not persisted in the App's local database.
You can manage or delete fitness data written to Health Connect through the controls provided by Health Connect.
You can also revoke Fitness Band – Health Tracker's access to Google Health or Health Connect at any time through the relevant Google or Android settings.
When you revoke access, Fitness Band – Health Tracker can no longer access the corresponding Google Health data or perform the corresponding write operations unless you authorize access again.
Revoking access does not necessarily delete data that has already been stored in Google Health or Health Connect. Such data can be managed or deleted through the corresponding Google controls.
If you have other personal information stored by us, you may request its deletion by contacting us at [email protected].
Data Security
We use reasonable administrative, technical, and organizational measures to help protect information processed by the App.
For Google Health data specifically:
- Google Health API communication occurs over HTTPS.
- Google Health API data is processed on the user's Android device.
- Google Health API responses are held in application memory and are not persisted in our database or uploaded to our servers.
- OAuth access tokens are stored only in the App's private storage and are protected by the Android application sandbox and platform file-based encryption.
- The App does not store Google OAuth refresh tokens.
- The App does not contain or store a Google OAuth client secret for a backend service.
- Google OAuth authorization can be revoked when the user signs out.
While we take reasonable steps to protect the information we process, no security measure is perfect or impenetrable, and no method of data transmission or storage can be guaranteed against every possible interception or misuse.
User Rights
Access and Control
You can control the permissions granted to Fitness Band – Health Tracker through the relevant Google Health and Health Connect settings.
You may grant or revoke access to your health and fitness data at any time.
Data Deletion
You can manage or delete Google Health and Health Connect data using the controls provided by Google and Android.
Because Fitness Band – Health Tracker does not persist Google Health data in a developer-controlled backend or database, there is no developer-side Google Health data repository to delete.
For other personal information that we independently store, you may request access or deletion by contacting our support team at [email protected], subject to applicable legal requirements.
Changes to This Policy
We may update this Privacy Policy periodically to reflect changes to our services, data practices, or applicable requirements.
When we make changes, we will update the "Last Updated" date at the beginning of this Privacy Policy.
We may also notify you of significant changes through the App or other appropriate communication channels.
We encourage you to review this Privacy Policy periodically to stay informed about how we handle your information.
