1. Overview

This Privacy Policy explains how ChainTrack handles information when you use the ChainTrack mobile application. ChainTrack is an offline-first habit tracker: the app itself does not collect or transmit personal information.

In short: your habit data is stored locally on your device. ChainTrack has no user accounts, cloud sync, network connection, advertising, or tracking.

2. Information stored on your device

When you use ChainTrack, the app stores the information you choose to enter so its features can work. This information remains in the app’s local storage on your device.

Habits

Habit names, colors, schedules, weekly goals, and active or archived status.

Progress

Completion dates and the streak, history, achievement, and insight calculations derived from them.

Notes and settings

Notes you add to completed days and your selected light, dark, or system theme.

ChainTrack does not collect, upload, sell, or share this information with ChainTrack or any third party.

3. Information we do not collect

ChainTrack is built without an account or backend. The app does not collect the following information:

  • Your name, email address, phone number, or account credentials
  • Your location, contacts, photos, files, or device identifiers
  • Advertising identifiers, analytics events, or behavioral profiles
  • Habit data, progress, notes, or backup files through a network connection

4. Backups and sharing

ChainTrack lets you export your local data as a JSON backup and import it later. These actions happen only when you choose them.

  • An exported backup is saved using the Android file destination you select; it is not uploaded to ChainTrack.
  • If you send or upload a backup to another person, app, or service, that recipient’s privacy policy applies.
  • Importing a backup replaces the current local habits and completion history after you confirm the action.

5. Permissions and third-party services

ChainTrack does not require an account, network access, or special device permissions to provide its core features. The app does not include third-party advertising, analytics, crash reporting, or cloud-sync services.

The Android operating system and the app store where you download ChainTrack may process technical information under their own privacy policies. That processing is separate from ChainTrack’s app functionality and is outside our control.

6. Your control over local data

You can edit or delete habits and their history inside the app. You can also remove ChainTrack’s local data through your Android device settings or by uninstalling the app. Exported backup files are separate files and must be deleted from the location where you saved them.

7. Children’s privacy

ChainTrack does not knowingly collect personal information from children or anyone else. Because the app does not send personal information to us, there is no account-based or online child data collection.

8. Changes to this policy

We may update this Privacy Policy when ChainTrack’s features or data practices change. The effective date at the top of this page will be updated when a new version is published.
