How trust works

The app pulls in what you follow — RSS and Atom feeds, web pages, YouTube channels, Mastodon, Nostr — extracts the readable article from each, keeps it, and can summarize it.

SummaReader pulls in what you follow — RSS and Atom feeds, web pages, YouTube channels, Mastodon, Nostr — extracts the readable article from each, keeps it, and can summarize it.

  • Summarization runs on the device by default, with a model you download once. You can point it at your own server or a cloud API instead.
  • Sync is optional, end-to-end encrypted, and self-hosted. The sync server holds only ciphertext.
  • No accounts. No analytics. No telemetry. No crash reporting.

This is the free build, and it is a complete reader: no limit on how many sources you follow. Premium is a separate application and is not listed here.

Android builds are arm64 only. This build and the Google Play build are signed with different keys; Android will not replace one with the other.

Release notes

Signed Linux updates. The AppImage now installs an update only when the release's list of files carries our signature and the download matches it, comes from GitHub over https, and arrives complete. Anything else is refused with a sentence that says why, and nothing is changed. Releases before this one were not signed, so an older version installs this one without the check, and this one checks every update after it.

A recovery code is bound to its server. Joining with a recovery code now signs which server asked as well as its one-time number, when the server asks for that, so a server that passes another one's number along gets a signature the other one refuses. A server that does not yet ask is joined as before.
