Proton Calendar is pitched as offering encryption for all tournament minute print, as successfully as “excessive-efficiency elliptic curve cryptography (ECC Curve25519)” to lock it. The online app version of Proton Calendar is open source, with the code for cell apps to attain support subsequent, Proton says. Proton additionally notes that it never finds out who it is probably going you’ll additionally have faith invited to an tournament, and it enables for titillating of us outside the Proton ecosystem, letting of us “cryptographically study that it changed into you who invited them.”
