Privacy Policy

Last updated: 2026-06-14

The short version

Hearken is built to be private by design. Text-to-speech runs entirely on your device. There are no accounts, no servers, and your books never leave your device.

What we collect

Nothing. Hearken does not collect, transmit, or store your personal data or the contents of your library.

Network usage

The only network request Hearken makes is to download the on-device voice model the first time you use narration. This download contains no personal information.
