Privacy policy

Effective August 23, 2026

Bluetooth Sleep Timer is designed to work locally, without an account, advertising, behavioral usage analytics, or cloud sync. Release builds use limited crash diagnostics to improve reliability.

Who we are

This policy applies to the Bluetooth Sleep Timer Android application, package name app.chaseos.bluetoothsleeptimer. The app is developed by Chaseos Apps. For privacy questions, email chaseosapps@gmail.com.

Information processed on your device

Bluetooth Sleep Timer stores the information needed to provide the features you choose:

• Managed Bluetooth devices: Android association identifiers, device identifiers made available by Android, system device names, optional nicknames, connection and compatibility results, and your device preferences.
• Timers and Schedules: durations, selected actions and devices, schedules, execution state, completion outcomes, and limited diagnostic reasons needed to show whether an action completed.
• App preferences: onboarding state, notification choices, timer behavior, reconnect settings, and your last-used selections.
• Full Access status: the product identifier, purchase state, last verification time, and whether Google Play and RevenueCat verified the entitlement. Purchase tokens are handled by the purchase services and are not stored in the app's feature database.

This content remains in the app's private local storage. Chaseos Apps does not receive it. Android cloud backup and device-to-device transfer are disabled for the app. Clearing the app's storage or uninstalling it removes its local records, subject to Android and Google Play retaining platform-level records under their own policies.

Permissions and Android services

• Nearby devices and Bluetooth: used to list already-connected audio devices, let you approve a device through Android's Companion Device Manager, and request supported connection or disconnection actions for approved devices.
• Notifications: used to keep active timers visible and report timer or scheduled-action results according to your choices.
• Exact alarms, foreground services, and boot or time changes: used to run user-scheduled actions reliably, recover active schedules after a restart, and recalculate them after clock or time-zone changes.
• Media and communication state: checked on-device so the app can attempt a media Pause and avoid interrupting calls or communication sessions.

These capabilities are used only for the features described in the app. Bluetooth Sleep Timer does not use location permission and does not scan for unrelated nearby accessories.

Google Play purchases and RevenueCat

Full Access is an optional, permanent one-time purchase processed by Google Play. The app requests localized product information, starts the Google Play purchase flow, checks purchase status, and restores an existing purchase. Google Play handles payment credentials; Bluetooth Sleep Timer and Chaseos Apps do not receive complete payment-card details.

Bluetooth Sleep Timer uses RevenueCat as a service provider to verify the purchase and keep Full Access available after a restart, reinstall, or restore. The RevenueCat SDK creates a random App User ID for this installation. RevenueCat may process that identifier, the app and product identifiers, purchase and entitlement status, transaction or purchase history supplied by Google Play, and limited app or device information needed to operate, secure, and diagnose the purchase service.

The app does not identify the RevenueCat record with a Bluetooth Sleep Timer account and does not send RevenueCat your managed Bluetooth devices, device names, timers, schedules, media information, or app preferences. Chaseos Apps can view the pseudonymous customer record, transaction status, and Full Access entitlement in RevenueCat to provide purchase support and investigate purchase failures.

Google's processing is governed by its own policies, including the Google Privacy Policy and Google Play Terms of Service. RevenueCat describes its processing and retention in the RevenueCat Privacy Policy.

Google Play ratings and reviews

After you have successfully used the timer, the app may ask Google Play to display its native in-app review flow. Google decides whether the review card appears. If you choose to submit a rating or written review, Google Play processes that information and may publish it with your Play profile. A review submitted from a closed testing track may instead be shared privately with Chaseos Apps. Bluetooth Sleep Timer does not read or store your review response in its local app data.

You can edit or delete a submitted review through your Google Play Store or Google Account. Google's processing is governed by the policies linked above.

Crash diagnostics

Release builds use Firebase Crashlytics to help identify crashes, app-not-responding errors, and other technical failures. Reports may include stack traces, app and device information, and installation identifiers. They are used only to diagnose and improve app reliability, not for advertising or behavioral analytics.

Bluetooth Sleep Timer does not intentionally include Bluetooth device details, schedules, media information, purchase data, or user identifiers in these reports. Google processes this information through Firebase Crashlytics under its privacy and retention policies.

Information sent to Chaseos Apps

Bluetooth Sleep Timer has no developer-operated server. Chaseos Apps can access the limited purchase and entitlement records in RevenueCat, the diagnostic reports described above, and information you choose to provide, such as a support email or a review shared by Google Play. This information is used to provide Full Access, improve reliability, investigate purchase problems, and respond to support requests.

Sharing, selling, and tracking

Chaseos Apps does not sell personal information, share it for advertising, or use behavioral usage analytics in Bluetooth Sleep Timer. RevenueCat processes the limited purchase information described above to provide and support Full Access. Google processes limited diagnostic information through Firebase Crashlytics. Android system services process device associations and requested background work, and Google Play processes purchase activity and any rating or review you choose to submit as needed to provide those platform features.

Retention and deletion

App-local information remains until you remove it in the app, clear app storage, or uninstall Bluetooth Sleep Timer. Because there is no Bluetooth Sleep Timer account or developer-operated database, Chaseos Apps has no app account record to delete. RevenueCat purchase records, Firebase diagnostic reports, and Google Play records are retained under their respective policies and may be retained where required for transaction, security, fraud-prevention, or legal purposes.

To request deletion of data that Chaseos Apps can control in RevenueCat, Firebase, or support systems, contact chaseosapps@gmail.com. Include enough non-sensitive detail for us to locate the relevant record, but never send a purchase token, password, authentication code, or complete payment-card information. Deleting a service-provider record does not delete transaction records that Google Play independently retains.

Security

The app keeps feature data in private local storage, disables app-data backup and transfer, and limits remote processing to the services disclosed in this policy. No security measure can eliminate every risk, so keep Android and your device security updates current.

Children's privacy

Bluetooth Sleep Timer is a general-audience utility and is not directed to children under 13. Chaseos Apps does not knowingly seek personal information from children.

Changes to this policy

This policy may be updated when the app's features, dependencies, or legal obligations change. Material changes will be reflected on this page with a new effective date.
