Android APK installation and updates

Install only a verified release from this website after one is published.

There is no public APK today. Debug and candidate builds are test-only and must not be downloaded or installed by the public.
A public release will show its version, checksum and signing identity. Do not install files forwarded in chat, modified APKs or builds from look-alike sites.
Updates may require installing a newer signed APK. Back up nothing by copying app files; account data and eligible offline packs follow their documented service rules.
