How does Dotjamr work?

You write a message, Dotjamr creates a one time link, and the message is deleted after it’s opened successfully.

Is my message encrypted?

Yes. Your message is encrypted in your browser before it’s sent. The link contains the key needed to decrypt it.

Can Dotjamr read my message?

No. The server stores encrypted text. Decryption happens in the recipient’s browser when they open the link.

What does one time access mean?

After the link is opened successfully, the encrypted message is deleted. If someone tries to open it again, it won’t be there.

What happens if the link expires?

If nobody opens the link before the expiry time, the message is deleted automatically.

Do I need an account?

No account, no inbox, no message history. Just create a link and share it.

Clear and transparent.

Privacy

DotJamr is designed to minimise stored data and reduce long term exposure of sensitive information.

No accounts

DotJamr does not require user accounts. There are no profiles, inboxes, or message history tied to individuals.

Client side encryption

Messages are encrypted in your browser before transmission. The server stores encrypted data only and does not store readable message content.

Link mode

In Link mode, the decryption key is stored in the URL fragment. Under normal web behaviour, browsers do not send this fragment to the server. Anyone with the full link can open the message once.

Keyword mode

In Keyword mode, the encryption key is derived from a keyword chosen by the sender. The server never receives this keyword. Without the correct keyword, the encrypted message cannot be decrypted.

Automatic deletion

Messages are deleted immediately after a successful open. If a message is not opened, it is automatically deleted after the selected expiry time.

Technical logs

Like most web services, DotJamr may collect limited technical information such as IP addresses, browser type, and timestamps in server logs. This information is used for security, abuse prevention, and operational stability.

Third party services

If third party services are introduced in the future, such as analytics, payment providers, or hosting infrastructure, they may process limited technical data as part of operating the service. DotJamr does not sell personal data.

User responsibility

Once a message is viewed, the recipient may copy, store, or screenshot it. DotJamr limits message persistence but cannot control actions taken after viewing.
