Share a private note with browser encryption
Use Reiven to send a short private message, setup instruction, or confidential handover. The note is encrypted on your device before it reaches the server.
From text to an encrypted link
- Open note sharing and write your text in the payload box.
- Choose a strong password or enable QR Mode for a random browser-generated key.
- Encrypt and upload, then send the resulting link or access code.
- The recipient opens the link, decrypts locally, and can read the note or save it as a text file.
For a manually chosen password, use a different communication channel from the link when practical. The service cannot recover a lost password.
Temporary notes with explicit deletion
Notes expire after 24 hours and can be removed earlier with the deletion link. Receiver deletion is enabled by default. A recipient can delete the server copy once it is no longer needed.
Notes are not automatically destroyed on first reading. A person who can read a note can also copy or save it, and server deletion cannot remove copies they already hold.
The encrypted note is held in RAM. A server restart or crash can make it unavailable before the scheduled expiry. Keep any information you need in your own records.
Limits and privacy
A note can contain up to 10 MiB of encoded text; short messages are easier to use on mobile devices. It is stored as an encrypted note payload with the upload name note.txt.
Encryption protects the content, not a compromised browser or a link shared with the wrong person. QR links contain their own decryption key and should be treated as the secret itself.
