It doesn't phone home

No account. No subscription. No ads. No analytics.

Your documents are read on your phone by software running on your phone. The text never leaves it, and neither does the audio. The app talks to the network exactly once per voice you choose to download, and never again.

That isn't a promise about our intentions — it's a property of how it's built, and the source is public so you can check. Privacy policy

Installing it

It isn't on the Play Store yet. Download the APK, open it, and allow your browser to install apps when Android asks — that prompt is normal for anything from outside the store.

Every release publishes a checksum, so you can confirm you got the file we built:

sha256sum papervoice-1.0.0.apk

For automatic updates, point Obtainium at the GitHub repository.

Open source, and why

Papervoice is GPLv3 — not as a stance, but because the component that turns letters into sounds is, and it runs inside the app. So the source has to be open, which seems a fair trade for software that reads your books.

The voices are other people's work, released freely: mostly trained from public-domain LibriVox recordings. Every one is credited with the licence it was checked against.
