Cookie policy
Last updated August 2026. The list below is kept accurate to what the site actually sets, and is updated the moment that changes.
Public tools
The tools directory, tool pages, and API set no cookies. There is nothing to opt out of.
Admin area
The protected admin area (not publicly accessible) uses a single, secure, HttpOnly, SameSite session cookie to keep an authorized administrator signed in. It is strictly necessary for that feature to function and is not used for tracking.
