Last year, we released Proton Calendar beta on Android, marking a significant milestone in the expansion of Proton’s privacy ecosystem. We’ve been busy incorporating your feedback over the past year, and today we’re happy to officially launch Proton Calendar on Android!
Yes but as with most things with proton they lock down the good features behind a payment model, to each their own I know we all gotta make money somehow.
I’ve been using cryptpad.fr for a while which is opensource and self-hostable, you canmake multiple calendars and share among a team but proton has more features otherwise. Obviously not one to one with proton since they are an email service and this is an office suite but they compliment each other nicely. I only use proton for their email since I have simple needs.
