Android Privacy Policy

This Privacy Policy explains how FlossBros ("we", "our", or "us") collects, uses, shares, retains, and protects information when you use the FlossBros application for Android (the "Android App"). The iPhone privacy policy remains available separately.

Information We Collect

Account and profile information

• Email address, display name, Firebase user ID, and sign-in provider.
• Profile choices such as your avatar and app preferences.

Flossing, habit, and oral-health information

• Floss-session dates, times, streaks, history, experience points, badges, and lesson progress.
• Optional indicators you provide about bleeding or pain and optional free-text notes attached to a floss session.
• Reminder settings and whether you choose to be asked about gum health.

Because bleeding, pain, and related notes may describe your health, we treat them as sensitive information. We use them to provide your tracking history and app features; we do not use them for advertising.

Social and family information

• Friend requests, connections, nudges, high-fives, and related interaction status.
• Family group membership, invitations, and challenge participation.
• Your display name, avatar, streak, level, experience points, Premium status, and recent floss activity may be visible to friends or family members you connect with.

App activity, diagnostics, and identifiers

• App interactions such as sign-up, sign-in, floss logging, social actions, notification opens, onboarding, and paywall activity.
• Crash reports and diagnostic information needed to identify and fix reliability problems.
• Device and app-instance identifiers, Firebase installation information, app version, operating-system information, and a push-notification token.
• Firebase Analytics is associated with your Firebase user ID after sign-in so that app activity can be understood across sessions.

Purchases and subscriptions

If you use a paid Android plan, Google Play and our subscription entitlement provider process product, purchase, renewal, expiration, and entitlement information. We use that information to unlock and restore Premium features. We do not receive or store your full payment-card number; payment processing is handled by Google Play.

Information we do not collect

The Android App does not request precise location, your address book, photos, audio recordings, or general files. We do not use the Google Advertising ID for advertising or cross-app tracking, display ads, or sell personal or health information.

How We Use Information

• Create and secure your account and keep your data synchronized.
• Provide floss tracking, streaks, reminders, education, achievements, friends, families, and challenges.
• Send transactional push notifications that you enable.
• Manage, validate, and restore Premium access.
• Measure feature use, diagnose crashes, prevent abuse, and improve the Android App.
• Respond to support, privacy, security, or legal requests.

Service Providers and Disclosure

We disclose information only as needed for the following purposes:

• Google Firebase: Authentication, Cloud Firestore, Cloud Functions, Analytics, Crashlytics, Cloud Messaging, and app-instance services.
• Google Play: Android distribution, security, billing, subscriptions, and purchase processing.
• RevenueCat: Subscription and entitlement verification when Android Premium purchasing is enabled.
• People you choose to connect with: The friend- and family-visible profile and activity fields described above.
• Legal and safety reasons: When reasonably necessary to comply with law, enforce our terms, prevent fraud or abuse, or protect users and our rights.

These providers process information under their own terms and privacy commitments. See Firebase privacy and security, Google's Privacy Policy, and RevenueCat's Privacy Policy.

Security

Data is encrypted in transit using transport-layer security. Our cloud providers also apply encryption at rest and access controls. We limit access to the systems needed to operate FlossBros, but no online service can guarantee absolute security.

Retention and Account Deletion

We keep account data while your account is active and as needed to provide the service. You may request permanent deletion from Settings > Account > Delete Account in the app or follow the instructions on our account-deletion page.

Account deletion removes your Firebase Authentication account, profiles, floss logs and notes, social connections, achievements, and associated family information from the active service. Processing is normally prompt but may take up to 30 days; residual backup copies may take up to 90 days to expire. We may retain limited security, support, legal, tax, accounting, or fraud-prevention records where required, and deidentified or aggregated analytics may remain. Google Play, RevenueCat, and other service providers may also retain purchase, diagnostic, or security records under their own legally required and documented retention periods.

Deleting your shared FlossBros account removes access on Android and iPhone. It does not cancel or refund a subscription. Cancel a Google Play subscription separately in Google Play subscriptions before deleting your account.

Your Choices and Rights

You can edit profile and reminder settings in the app, control notification permission in Android settings, disconnect friends, and delete your account. Depending on where you live, you may also have rights to access, correct, delete, restrict, object to, or obtain a copy of personal information. Contact us to exercise a right we cannot fulfill in the app.

Children

FlossBros is intended for people aged 13 or older. We do not knowingly collect personal information from children under 13. Contact us if you believe a child under 13 has provided information.

Health Disclaimer

FlossBros is a habit and education app, not a medical device. It does not diagnose, treat, cure, or prevent any disease and is not a substitute for advice from a dentist or other qualified health professional.

International Processing

Our providers may process information in countries other than where you live, including the United States and countries in the European Economic Area, subject to their data-processing terms and applicable transfer safeguards.

Changes to This Policy

We may update this policy as the Android App or legal requirements change. We will post the updated policy here and revise the date above.
