Standard Notes

For people whose notes hold things they would never put in an email: password hints, health details, journal entries. Standard Notes encrypts everything end to end, and even the free plan includes unlimited device sync, offline access and a full data export in plaintext or encrypted form, which is a generous exit for a free tier. The trade-off is that free means plain text notes; richer editors sit in the paid plans at $90 or $120 a year. Proton bought it in 2024 and promised it would stay open source, freely available and fully supported, which eases the usual worry about a small privacy app disappearing.
