Privacy Policy

Last updated: January 2025

SpiritFit ("we", "our", "the app") is committed to protecting your privacy. This policy explains what information we collect and how we use it.

1. Data We Collect

SpiritFit can store your data in two ways depending on whether you sign in:

  • Without sign-in (default): All data is stored locally on your device using browser localStorage. Nothing is sent to any server.
  • With Google Sign-In (optional): Your data is securely stored in Google Firebase (Firestore), a cloud database operated by Google, so you can sync across devices. This includes your name, daily habit state, streak, history, and preferences.

We collect your name (optional), daily habit tracking data, language and mode preferences, and streak and history data. We never sell your data to third parties.

2. Advertising

SpiritFit displays advertisements through Google AdSense to support free access to the app. Google AdSense may use cookies and device identifiers to serve personalized ads based on your interests.

You can opt out of personalized advertising by visiting Google Ad Settings.

3. Cookies

We use localStorage (not cookies) for app functionality. Our ad partners (Google AdSense) may use cookies for ad personalization.

4. Third-Party Services

We use the following third-party services:

  • Google Firebase (Authentication & Firestore) — for optional account sign-in and cloud data storage. See Firebase Privacy.
  • Google AdSense — for advertising. See Google Privacy Policy.

5. Children's Privacy

SpiritFit is not directed at children under 13. We do not knowingly collect information from children.

6. Changes

We may update this policy occasionally. Continued use of the app means you accept the updated policy.
