PrivacyNotes.app - Anyone try Pro Plan?

It is seems a product from PrivacyTools.io

PrivacyNotes is a Swiss-based, zero-knowledge productivity app that combines notes, tasks, file storage, password vault, and wellness journaling in a single application. It uses E2EE with XChaCha20-Poly1305 encryption and BIP-39 key derivation, ensuring the service provider cannot access user data.

Anyone try Pro plan?

Not really Open Source

Oh. Thank you for your reply @Kris . This is a key point for consider.

Why not use something recommended in Notebooks - Privacy Guides ?

I like Joplin very much. I use it with git sync.

Thank you for your support. It is a good idea. I just consider for some others. I think I will try Joplin and Standardnotes.
