Yeah, it seems Buddists are more focused on mindfulness and being fully in the moment, which is kind of the opposite of escapism. Also understanding duhkha, sometimes translated as unease due to “not having what one wants” or “having what one doesn’t want” and accepting it and living with it rather than striving to eliminate duhkha.
…and of course Buddhists have been known to kill other Buddhists for being the wrong kind of Buddhists, so ymmv
Do note, because it’s using email, the recipient and sender are not private, along with the time, and probably the relative size of the messages.
The specific content of each message should be private as long as the encryption is done well. I haven’t looked at it so I don’t know if it implemnts safeguards to verify who you’re messaging with (besides using the email address) and I don’t know if it uses PFS (Perfect Forward Secrecy) to protect against a key getting compromised.
