Privacy Policy

Sizeling is designed to work offline and respects your privacy. This policy explains what data we collect, why, and how we protect it.

Data We Collect

Data stored on your device

The following data is stored locally on your device using SharedPreferences and never leaves your device unless you explicitly enable cloud sync:

• Your size profile (shoe, tops, jeans measurements)
• App settings (language preference)
• Recent conversion history (last 5 conversions)
• An anonymous ID generated on first launch (used to identify your data if you enable sync)

Data synced to the cloud (optional)

Sizeling works fully without an account. If you choose to sign in with Google to sync your profile across devices, your size profile and anonymous ID are stored in our Supabase database. You can delete this data at any time from the Delete Account page.

Analytics

We use Firebase Analytics to collect anonymous, aggregated usage data (e.g., which features are used, app crashes). This data cannot be used to identify you personally. You can opt out via your device's advertising settings.

Error tracking

We use Sentry to capture app errors and performance issues. Error reports may include device type, OS version, and app version. They do not include your size data or personal information.

Advertising

Sizeling displays ads via Google AdMob. AdMob may use your device's advertising ID to show relevant ads. You can reset or opt out of personalized ads in your device settings under Google > Ads.

Push Notifications

If you grant notification permission, Sizeling subscribes to broadcast topics (announcements and promotions) via Firebase Cloud Messaging. No personal notification tokens are stored on our servers.

Data We Do Not Collect

• Your name, email address, or phone number (unless you sign in with Google)
• Your precise location
• Your contacts or photos
• Any payment information

Third-Party Services

Sizeling uses the following third-party services, each with their own privacy policies:

• Supabase (optional cloud sync) — supabase.com/privacy
• Google AdMob — policies.google.com/privacy
• Firebase Analytics & Messaging — firebase.google.com/support/privacy
• Sentry — sentry.io/privacy

Children's Privacy

Sizeling does not knowingly collect data from children under 13. If you believe your child has provided personal information, please contact us to have it removed.

We may update this policy from time to time. Changes will be posted on this page with an updated date.
