Study topics, CSV files, card answers, session logs and generated results are processed in your browser. Results expire after 24 hours; session history persists until you delete it or clear this site's browser data. Shared devices may expose saved data. The web server receives normal request metadata such as IP address and user agent and may keep operational access logs. No Analytics or advertising code is installed in this release. Contact email uses your email provider and sends the message to the site contact. You can delete a result or session history from the tool interface.
