What ZeroNote is

ZeroNote brings notes, password management, bookmarks, document storage and two-factor authentication into a self-hosted web app organized with smart tags. Notes support Markdown, code syntax highlighting, attachments and search across titles and content. Tags can provide structured password fields and generate TOTP codes with a countdown timer. The app works offline, storing data in the browser’s IndexedDB, and its README says notes are encrypted on the device with AES using a master password that stays there. Optional synchronization can use direct WebRTC between devices, S3-compatible storage or Nostr relays. Encrypted JSON backups include attachments, and deleted notes can be restored before permanent removal; they are automatically purged from the device after seven days. ZeroNote is free under the MIT license, works in a browser on any device and can be installed as a PWA. However, the repository is archived and read-only, and development and support have stopped. There is no master-password recovery, so losing that password means the data cannot be decrypted.
