What data does this website process?
Local tool records
Local records persist across visits on the same browser. Export and keep backups privately. Clearing site storage removes records; private browsing may not retain them.
Contact messages
The form requests a message, optional email and source URL. These are used to review corrections and reply where appropriate. Do not submit sensitive personal data. Requests about deletion can be made through the contact form. Messages remain in the site-specific Cloudflare D1 database until editorial review or an applicable deletion request is handled; no fixed automatic retention period is currently implemented. Daily abuse prevention stores a date-specific hash of the requesting IP, not the raw IP, and removes old counters during later submissions.
Analytics and cookies
Google Analytics 4 loads only after Allow analytics is selected. It can set analytics cookies and process page views, device/request metadata and named tool interactions. Tool records, contact text and email addresses are not event parameters. Choose Essential only to stop future collection; previously set cookies may remain until you clear them in browser settings. Local notebook data is separate from analytics consent.
