In their own words
PrivacyNotes
PrivacyNotes is an end-to-end encrypted workspace for notes, tasks, files, a vault, journals, and bookmarks. It encrypts notes on the device before synchronization using XChaCha20-Poly1305, with keys derived from a 12-word BIP-39 phrase. Its local-first design supports reading, writing, and searching offline, then syncs changes when connectivity returns. The synchronized copy is stored in Zurich, Switzerland, as encrypted data rather than readable note text. Users can create a vault without email or sign in with Google, Apple, or GitHub; provider sign-in offers server-held or device-only key custody. Imports cover many note, journal, password, and bookmark services, along with Markdown files. PrivacyNotes has no AI features or background AI processing and does not train models on user content. Its web, desktop, and mobile apps and encryption code are published on GitHub under the AGPL. The Free plan costs nothing forever; Pro costs $48, paid once. Under self-custody, losing the phrase without a signed-in device means the company cannot recover notes.
