Lost your sync key?
Nobody can recover it. Your library is encrypted with the key, and Hidden Word never keeps a copy.
Look in your password manager under this site's address. If you added a passkey, try Unlock with passkey. On a device that's still unlocked, open the ••• menu and choose Show sync key.
If none of that works, create a new library. If you exported a file, Import brings your highlights back.
Save your sync key
This key is the only way into your library. Nobody can reset or recover it, and anyone who has it can read your highlights. Save it in your password manager now.
Add a passkey to unlock this library without typing the key in other browsers on this site.
No highlights yet.
Colors
Name a color to use it as a category. Other apps show your own colors as you made them, or as yellow.
Sync
Your library is always on this device first. Choose how it reaches your others. Any mix works, and so does none.
This browser can't sync a folder. Use Export and Import to move a file by hand.
For developers
Hidden Word is an open format any app can use. Read the spec, or start with the quick start.
Danger zone
Erasing removes this library from the server, the sync folder and this device.
