Back up notes to your own cloud

WebF1 Pad can back up notes to any S3-compatible storage you control. Encryption happens on your device — the server stores ciphertext only.

Tip: if you use the Dropbox desktop app, you can also point a notes folder at your Dropbox folder with plain Save As… — the desktop app syncs it continuously, no setup needed.

Configure the connection

1. Open Settings (the gear button, or View → Settings) and go to the Cloud backup tab.
2. Under S3, tick Enable S3 backup, then fill in:
   • Endpoint - e.g. https://s3.us-east-1.amazonaws.com or your MinIO server.
   • Access key / Secret key - from your provider. Both accept a file:/path/to/secret reference to a file containing the value instead of pasting the secret itself.
   • Bucket - created automatically on first save if missing.
   • Passphrase - the key your notes are encrypted with. If you lose it, the backups cannot be decrypted.
3. Click Test, then Save.

Save and open cloud notes

• File → Save to Cloud (Ctrl+Alt+S) uploads the current note to the active backend. The first save asks for a remote name.
• File → Open from Cloud lists your backed-up notes and opens one into a tab. Opening one already open activates that tab instead of duplicating it.
• Once a note has a cloud copy, it re-uploads automatically as you edit - no resaving needed.

Privacy notes

• Encryption is AES-256-GCM with a key derived from your passphrase (PBKDF2, 600k rounds, per-save random salt).
• Images pasted into the note are embedded in the note text, so a cloud copy is complete on its own.
• The storage provider never receives your passphrase, keys or plaintext.
