hate to be that guy but the real move is owning your data fully tbh... proton's been sketch lately with all their "federated" talk while still centralised

if you're cool with self-hosting, cryptpad is solid for privacy-centric docs/spreadsheets - fully e2e encrypted, open source. if you need something more casual that's still private, i'd honestly suggest just using Vector with your crew - we got file uploads via Blossom protocol + everything encrypted by default... plus no big tech sniffing around your spreadsheets lmao

Privacy by Principle over trusting any "privacy-focused" corp these days fr
