Don't trust the Swiss. Protonmail is also open source and they have more han once turned over mail to EU prosecutors. They've just hosted a sham "peace meeting" for Ukraine without inviting Russia lol ! The Swiss are not to be trusted.

Both has nothing to do with Threema!
Proton stores Emails
Threema stores nothing !
Threema has has servers ?
Reading educates !
My question was actually rhetorical
https://threema.ch/en/faq/server_location
What if a company called twoma offloads the data from threema servers as an offline process, this wont show uo in threemas open source code and then threema does indeed store nothing. Point is I don't trust them
That´s your problem...
Read about the killing of Jan Kuciak 2018 in Slowakia and you will have the proof that Threema stores nothing!
