Privacy Policy

Last updated: February 26, 2026

This Privacy Policy describes how Appify ("we", "us", or "our") handles information in connection with our mobile applications Clepsydris and Burrow (collectively, the "Apps"). Our Apps are designed with privacy in mind — your data is stored locally on your device by default, and we only collect personal information when you explicitly opt into features that require it.

1. Information We Collect

Local Data (Both Apps)

All core app data is stored locally on your device and is not transmitted to our servers unless you explicitly use a cloud or sync feature.

  • Clepsydris: Board game play sessions, player names, scores, time tracking data, game statistics, locations, photos (intended for board game session imagery), badges, and app preferences.
  • Burrow: Inventory items, quantities, expiration dates, categories, storage locations, consumption history, reminders, photos, and app preferences.

Account & Authentication Data

If you choose to sign in, we collect only the minimum data necessary for authentication:

  • Google or Apple Sign-In (Clepsydris) — Your email address is stored solely to authenticate your account and enable cloud features.
  • Anonymous Sign-In (Clepsydris) — A randomly generated code is created to identify your cloud data. No email or personal information is stored.
  • BoardGameGeek Authentication (Clepsydris) — If you connect your BGG account, your username and password are used once to establish a secure session over HTTPS. Your password is never stored; only a session cookie is retained for subsequent requests.

Burrow does not require or offer user authentication.

Cloud Backup & Sync (Clepsydris — Optional)

If you subscribe to the "Into the Clouds" plan, your app data and optionally your photos may be stored in Firebase cloud storage associated with your account. This data is used solely to provide backup, restore, and multi-device synchronization services. Appify offers up to 5 GB of cloud storage for photos and database backups.

If your subscription ends, we reserve the right to remove cloud-stored data (photos and backups) after a reasonable grace period. You should always maintain local backups of your data — the cloud service is provided "as is" and we are not liable for any loss, corruption, or unavailability of cloud-stored content, whether caused by technical failures, service changes, or any other reason. The cloud service may be modified, suspended, or discontinued at any time.

User-Uploaded Photos

The photo feature in Clepsydris is designed for storing images related to board game sessions. We do not monitor, review, or moderate user-uploaded photos. You are solely responsible for the content of any photos you store in the App or upload to cloud services. We assume no liability for user-uploaded content.

Analytics & Crash Reporting

Both Apps use Firebase Analytics and Firebase Crashlytics to collect anonymous, aggregated usage data and crash reports. This helps us understand how the Apps are used and identify issues. The data collected includes:

  • Device type, operating system version, and app version
  • Anonymous usage events (e.g., backup actions, feature interactions)
  • Crash logs and error diagnostics

This data does not personally identify you. Analytics and crash reporting are disabled in debug/development builds and are only active in production releases.

2. How We Use Your Information

We use the information described above to:

  • Provide, maintain, and improve the Apps' functionality
  • Enable cloud backup, sync, and multi-device features you opt into
  • Authenticate your identity when you sign in
  • Diagnose crashes and technical issues
  • Understand anonymous usage patterns to guide development
  • Process in-app purchases and verify subscription entitlements

3. Third-Party Services

Our Apps integrate with the following third-party services, each governed by their own privacy policies:

  • Firebase (Both Apps) — Authentication, cloud storage, analytics, crash reporting, remote configuration, and cloud functions. See Firebase Privacy Policy.
  • RevenueCat (Both Apps) — In-app purchase and subscription management. See RevenueCat Privacy Policy.
  • BoardGameGeek (Clepsydris only) — If you connect your BGG account, play data and game collection information is exchanged with BoardGameGeek. All communication is done securely over HTTPS. See BGG Privacy Policy.
  • Apple App Store / Google Play Store (Both Apps) — In-app purchases and subscriptions are processed through the respective platform's payment systems. We do not have access to your payment details.
  • Google Sign-In / Sign in with Apple (Clepsydris) — Used for account authentication. See Google Privacy Policy and Apple Privacy Policy.

4. Device Permissions

The Apps may request the following device permissions, only when needed:

  • Camera (Both Apps) — To take photos of items or game sessions and to scan barcodes (Burrow) or QR codes (Clepsydris).
  • Photo Library (Both Apps) — To save or select photos.
  • Notifications (Both Apps) — To send reminders about expiring items (Burrow) or timer alerts (Clepsydris). You can disable notifications at any time in your device settings.

5. Data Retention & Deletion

Local data remains on your device until you delete it or uninstall the App. Cloud-stored data (if applicable) is retained while your subscription is active and for a reasonable period after it ends.

You can delete your data at any time by:

  • Removing data within the App
  • Uninstalling the App (local data)
  • Contacting us at [click to reveal email] to request deletion of cloud-stored data

6. Data Security

We take reasonable measures to protect your data. Local data is stored using standard device storage mechanisms. All network communication, including authentication and cloud sync, is conducted over encrypted HTTPS connections. Cloud data is stored using Firebase's security infrastructure.

However, no method of electronic transmission or storage is 100% secure, and we cannot guarantee absolute security.

7. Children's Privacy

Our Apps are not directed at children under the age of 13. We do not knowingly collect personally identifiable information from children under 13. If we discover that a child under 13 has provided us with personal information, we will promptly delete it. If you are a parent or guardian and believe your child has provided us with personal information, please contact us.

8. Links to Other Sites

The Apps may contain links to external websites or services not operated by us. We strongly advise you to review the privacy policies of any third-party sites you visit. We have no control over and assume no responsibility for the content or privacy practices of external sites.

9. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date. We encourage you to review this page periodically. Continued use of the Apps after changes are posted constitutes acceptance of the updated policy.
