Cookie policy

Last updated October 12, 2026

This policy explains the cookies and similar storage technologies used by OhMyFriends to operate OhMyFriends. The site includes Google AdSense, which may use cookies and similar technologies for advertising.

Session cookie

NamePurposeLifetime
mf_sessionMaintains and protects your chat session. It does not contain message text.Up to 365 days, renewable when the session is restored. Removed when you leave the chat; the server ends the session after one hour without activity in a visible, focused chat tab.

This cookie is used for session security and service functionality. It is restricted to the service and protected against access by page scripts.

Other browser storage

  • Chat storage: retains session information, encryption keys, encrypted message history, and pending messages. It is cleared when you leave the chat or delete site data. Message history may also be removed as messages expire.
  • Profile preferences: remembers your nickname, age, and gender to prefill the join form. These details remain after leaving the chat until you clear site data. They do not restore your previous session or conversations.
  • Sound preferences: remembers whether incoming-message sounds are enabled. This preference remains until site data is cleared.
  • Session closure: temporarily records a request to end your session if the connection is unavailable. This record is removed after the session is closed.

Typing indicators are temporary signals and do not save the text you are drafting.

Advertising cookies

Google AdSense may use cookies or similar technologies to deliver and measure advertisements and prevent fraud. Their use and duration depend on Google’s services and your choices. Learn more in Google’s cookie information and manage advertising preferences through Google My Ad Center.

Managing storage

You may change sound preferences using the sound control or leave the chat to end your session. Browser settings allow you to remove or block cookies and site storage. Required storage is necessary for the chat to function. Removing encryption keys makes previous conversations unrecoverable.

Closing a tab does not immediately end your session. You are signed out after one hour without a visible, focused chat tab. Reading the chat counts as activity; background tabs do not. Tabs in the same browser profile share the session. For more about information handling, see our Privacy policy.
