This Privacy Policy explains how Driftly collects, uses, and shares information when you use the app. For privacy questions or requests, use the contact email listed above.

1. Information We Collect

Driftly does not require you to create an account or provide any personal information to use the app. The following data is collected automatically by third-party SDKs integrated into the app:

App interactions – screen views and feature usage, collected by Firebase Analytics (Google).
Crash logs and diagnostics – error reports and performance data, collected by Firebase Crashlytics (Google) and, if enabled, Firebase Performance (Google).
Purchase history – in-app purchase records, processed by RevenueCat to manage your premium entitlement.
Device identifiers – anonymous installation or device identifiers used by Firebase and RevenueCat to associate the above data with your device session.

2. How We Use This Information

To provide and improve app functionality.
To diagnose crashes and fix bugs.
To verify and manage your in-app purchase entitlement.
To understand how the app is used in aggregate (no individual profiling).

3. Data Sharing

We do not sell your data. Data is shared only with the following third-party service providers as necessary to operate the app:

Google (Firebase) – analytics, crash reporting, and performance monitoring. Google Privacy Policy
RevenueCat – in-app purchase management. RevenueCat Privacy Policy

4. International Data Transfers

Our service providers, including Google and RevenueCat, may process data on servers located outside your country of residence. Where required by applicable law, those providers are responsible for applying appropriate safeguards for international data transfers under their own privacy and data-processing terms.

5. Data Retention

We do not keep a separate user account database for Driftly. Data handled by third-party providers is retained according to their own operational and legal retention requirements:

Firebase Analytics – retained according to Google's configured analytics retention settings. Google's data retention settings
Firebase Crashlytics and Performance – retained by Google for crash reporting, diagnostics, performance monitoring, and service operations in accordance with Google's privacy terms.
RevenueCat – retained as long as reasonably necessary to manage purchases, restore entitlements, prevent fraud, and comply with legal, tax, or accounting obligations.

6. Children's Privacy

Driftly is not directed at children. We do not knowingly collect personal information from children. In line with applicable laws, including the EU General Data Protection Regulation (GDPR) and the United States Children's Online Privacy Protection Act (COPPA), we do not knowingly collect data from users under the age of 16 in the European Economic Area or under the age of 13 in the United States and other jurisdictions. If you believe a child has provided us with personal information, contact us using the email address listed above and we will delete it.

7. Your Rights

Depending on your location, you may have rights to request access to, correction of, deletion of, restriction of, or objection to certain processing of your data, and in some cases data portability. You may contact us using the email address listed above for privacy requests. Because Driftly does not maintain user accounts, some requests may need to be handled directly by our service providers, but we will help direct your request where reasonably possible.

8. Changes to This Policy

We may update this policy from time to time. The “Last updated” date at the top will reflect any changes.

9. Contact

If you have questions about this policy, use the contact email listed above.

10. Permissions and Device Access

Driftly requests the following Android permissions that interact with device-level capabilities outside the app's normal lifecycle:

Alarm scheduling – Driftly uses Android's exact alarm capability (SCHEDULE_EXACT_ALARM) to fire wake-up alarms at user-configured times. This permission is used solely to deliver the alarm feature and is not used for any other purpose.
Boot receiver – Driftly registers a boot receiver (RECEIVE_BOOT_COMPLETED) to reschedule any pending alarms after your device restarts. No data is collected or transmitted during this process.
Background audio / foreground service – Driftly runs a foreground audio service while sounds are playing. Android displays a persistent notification while this service is active, allowing you to control playback from the notification shade. No data is collected or transmitted by this service.

11. Local Data Storage

Driftly stores your preferences and session state locally on your device, including active sounds, per-sound volumes, saved mixes or presets, theme, sleep timer, and alarm settings. This information is stored using the platform's standard preferences storage (Android shared preferences or, on iOS, NSUserDefaults). This data never leaves your device. It is not synced to any server and is not accessible by the developer or any third party.

12. Internet Access

Driftly requires internet access for the following background functions only. All sounds are bundled with the app and do not require streaming.

Firebase Analytics & Crashlytics – usage events and crash reports are queued locally and uploaded when a connection is available. See Google's Privacy Policy.
RevenueCat – verifies and restores your in-app purchase entitlement. The entitlement is cached locally after first verification; internet is required only for initial purchase and restore. See RevenueCat's Privacy Policy.
