🌿 Baesil Privacy Policy

1. What data Baesil collects

Baesil stores the following data locally on your device only using your browser's localStorage:

• Your name and age (for personalized recommendations)
• Cycle length and last period date
• Basal body temperature (BBT) logs
• Period flow, symptoms, mood, and energy logs
• Intimacy logs (if you choose to log them)
• Lifestyle preference (activity level, goal)

This data never leaves your device and is never sent to any server.

2. Advertising (free tier only)

If you use Baesil on the free tier, we display ads through Google AdMob. AdMob may collect:

• Device identifiers (Advertising ID / IDFA)
• Approximate location (country/region)
• App interaction data for ad performance measurement

On iOS, you will be asked for permission before any tracking occurs (App Tracking Transparency). You can deny this and still use Baesil — you'll see non-personalized ads.

Upgrading to Baesil Plus removes all ads entirely.

AdMob's privacy policy: policies.google.com/privacy

3. Subscriptions

Subscription payments are processed by Apple (App Store) or Google (Google Play). We use RevenueCat to manage subscription status. RevenueCat receives:

• An anonymous app user ID (not your name or email)
• Purchase transaction data from Apple/Google

RevenueCat does not receive any of your health data. Their privacy policy: revenuecat.com/privacy

4. Analytics

Baesil does not use any analytics services. We do not track how you use the app.

5. Data deletion

To delete all your data: Settings → Delete My Data, or uninstall the app. Because your data is stored locally, uninstalling the app removes it permanently.

6. Children

Baesil is intended for users 17 and older. We do not knowingly collect information from anyone under 17.

7. Changes to this policy

We will update this page if our practices change. Continued use of the app after changes constitutes acceptance.
