Privacy policy

You do not need an app account to read. The app keeps reading preferences, selected free chapters, bookmarks, reading progress where supported, and cached purchase entitlement information on your device. Device backup or transfer may preserve eligible preferences according to your operating system and account settings. We do not provide account-based reading sync.

English speech synthesis runs on your device. The app does not send book text or generated speech to a cloud TTS service. Chinese narration is not supported.

The app prepares approximately 175 MB of voice resources after a consent prompt. Rockhammer Labs delivers these files through Cloudflare at models.rockhammerlabs.com. Requests expose ordinary connection information such as IP address and request time to the delivery service. The model request does not include book text, bookmarks, generated audio or purchase status. Cloudflare processes connection and security information under its own privacy policy.

Apple StoreKit handles iPhone purchases; Google Play Billing handles Android purchases. The app uses store purchase information to determine whether Full Access is available and to restore eligible purchases. We do not receive your payment card details. Apple and Google process store account and payment information under their own policies. Purchases are separate between the two stores.

The first release does not send usage analytics to Rockhammer Labs or a product analytics service. The iPhone app keeps MetricKit diagnostics and performance reports on your device and does not upload them. Apple or Google may separately collect diagnostics under your system and store sharing settings.

Product analytics is not enabled in this release. We will update this policy before introducing a reporting service.

If you email us, we receive your email address and the details you choose to send, and use them to answer your request. Do not send passwords or full payment card information. We may ask for limited, redacted purchase information to investigate an entitlement problem.

Opening a link from the app takes you to a website with its own network and cookie behavior. This website is covered separately by the Rockhammer Labs website privacy policy.

You can decline voice preparation and continue reading. You can change reading preferences and remove bookmarks in the app. Uninstalling may remove local data; device backups, store purchase records and support correspondence are separate. For questions or requests concerning information you have provided to us, contact [email protected].
