Yes this is a Telegram client and yes it will break the Lemmy’s downvote world record but I still find this one very nice and “actively” maintained. There are not many good Telegram FOSS forks without Google integrations and similar stuff out there.
well yeah, just a simple private/public key solution for encrypting chat and cloud. transfer your private key to a forked desktop app and access your encrypted chat history from there as well.
just basic stuff, not something for people running from nation-state actors, but to prevent LLM ingestion and mass surveilance. but OP says that’s against Telegram’s ToS, so no dice here.
