Sleep Talk Privacy Policy

Effective date: 29 July 2026

Sleep Talk is an accountless Android app for recording and reviewing sleep sounds. This policy explains what the app accesses, what stays on your device, and what limited information third-party services may process.

Data that stays on your device

Sleep Talk stores audio recordings and the following related information in the app's private storage on your device:

• recording dates, times, durations, status, and error details;
• on-device sound classifications, confidence values, and noise levels;
• your ratings and corrections to detected sound types;
• optional before-sleep and after-waking check-ins; and
• your selected app language and locally cached purchase entitlement.

Audio is analyzed on your device using a model bundled with the app. Sleep Talk does not upload recordings, audio-derived details, check-in values, recording identifiers, or filenames to us, analytics, billing, or advertising services. The app has no Sleep Talk account, cloud backup, or cross-device sync. Android backup and device transfer are disabled for the app's private data.

Statistics, comparisons, correlations, filters, and reanalysis are calculated on your device from this stored information. If you choose to export a CSV file or local HTML report, Android sends the selected file only to the destination you choose. The destination then controls its copy.

Microphone and other permissions

• Microphone: used to record only after you tap Start recording and grant permission. Recording ends when you stop it or the enabled 12-hour limit is reached.
• Notifications: used to show and control an active foreground recording.
• Internet: used for the limited analytics, Google Play billing, consent, advertising, and policy links described below.

Anonymous usage analytics

When analytics is enabled in the app build, Sleep Talk sends screen names and action names to Umami. A request also includes the app version, Android version, language, screen dimensions, and package name. The network request necessarily exposes an IP address to the analytics host; Umami documents that it uses the address for location metrics without storing the address. Sleep Talk does not add names, email addresses, advertising identifiers, audio data, check-in values, sound results, recording identifiers, filenames, or purchase tokens to analytics events.

Google Play purchases

If you buy a product or subscription, Google Play processes the payment and associated account, transaction, and payment information. Sleep Talk receives product, purchase-state, and entitlement information needed to provide the purchase. It keeps the last successfully verified entitlement on your device and does not send purchase tokens to Sleep Talk servers or analytics. Google handles this information under the Google Privacy Policy.

Consent and advertising

The free version may show a non-personalized or limited Google Mobile Ads banner when you are not recording or reviewing sensitive details. Google's User Messaging Platform manages any privacy choices required in your region. Depending on your choices and Google's serving mode, Google may process an IP address and approximate location, app interactions, diagnostics, consent information, and device or account identifiers for ad delivery, measurement, and fraud prevention. Sleep Talk does not use or send recordings, check-ins, sound classifications, ratings, or purchase tokens for advertising.

Sharing and sale

We do not sell your personal or health-related data. Data leaves the app only as described above: limited events to the configured Umami analytics service, purchase and entitlement requests to Google Play, consent and ad requests to Google, files you deliberately export, or information required by law.

Retention and deletion

Recordings and related information remain on your device until you delete a night in the app or uninstall the app. Uninstalling permanently removes the app's private data because backup is disabled. Language and entitlement state remain until replaced or the app is uninstalled. Third-party services retain the limited information they process under their own policies. To request help concerning those services or this policy, use the developer contact details on Sleep Talk's Google Play listing.

Security

Sleep Talk uses Android private app storage for local data and encrypted HTTPS connections for network requests. No storage or transmission method can be guaranteed completely secure.

Changes to this policy

We will update this page and its effective date before materially changing how Sleep Talk handles data.
