This page explains what the site keeps so uploads, sign-in, and playback can work. It is not a promise that a public link is secret. A public link can be opened by anyone who has it.
Account information
When you register, the site stores the email address and the password hash needed to sign you in. Your profile name is stored so the account can be identified in the dashboard.
Password resets are sent to the email on the account. Keep that address current. We do not ask you to send a password in a reply to those messages.
Videos and viewing
Videos you upload are stored so they can be played, downloaded when that option is on, and deleted when you remove them. A password-protected video still exists on the server. The password only gates the watch page.
Basic technical details such as the time of an upload or a sign-in may be kept so the site can operate and so abuse can be investigated. Do not upload a video if you are not allowed to share it.
