We retain information only for as long as reasonably necessary to provide the service, maintain security, satisfy legitimate operational requirements, or comply with legal obligations. You may request deletion of information associated with your account by contacting us.

6. Data Security

We use reasonable administrative, technical, and organizational safeguards designed to protect information against unauthorized access, alteration, disclosure, or destruction. No online service can guarantee absolute security.
