OneTime - Send secure message

Share sensitive information with confidence. Create an encrypted message, send the token, and let the recipient open it only once.


OneTime - is a secure app for sharing sensitive messages in a simple and controlled way. It lets you create encrypted messages that can be opened only once, then become unavailable after they are viewed or after their expiration time. The app is designed for individuals, support teams, and businesses that need to share private information such as temporary passwords, access details, confidential notes, or sensitive files more safely.

You can create a secure message, set an expiration time, add an optional password, attach files, and share the token or read link with the recipient. OneTime also supports direct in-app delivery to available users after setting a visible alias.

The app displays content inside a protected viewer where possible, with sender-controlled permissions such as allowing or blocking copy and download. It supports light and dark modes, Arabic and English languages, and local token history for a limited period to help users access messages before they expire.

Privacy and Security:

OneTime uses an encrypted message system connected to the OneTime server. Each message receives a unique token and can be read only once based on its protection and expiration settings. Users can add an optional password and control whether copying or downloading is allowed. The app is built for temporary sensitive sharing rather than long-term message storage.
