Privacy information has moved

Upload and privacy information is now included in the Terms of Use.

Upload attribution

Uploads can include the source tool, a random anonymous session ID, the landing-page path, the referring hostname when available, and supported UTM campaign labels. The tab session expires after 30 minutes of inactivity. This helps group uploads and understand how visitors reach the tools; it does not identify a person. Attribution excludes full referral URLs, arbitrary query parameters, and advertising click IDs. Missing referral information appears as direct or unknown.
