@Tutanota There's a little mistranslation in your page (https://tutanota.com/es/#download). You say "Encriptamos todo" but should be "Ciframos todo". "Encriptar" is a false friend (it means litaraly "to put in a crypt/vault"). The correct translation to "encrypt" should be "cifrar".
@DracoMagister @Tutanota Thanks for that, I do write in Spanish and am not as fluent - and this topic and word can frequently pop up in computer discussions.
Muchas gracias!
