What this site does and does not collect
Static publication, browser-only worksheets and hosting request records.
The inspected edition has no login, wallet connection, analytics SDK or advertising tracker. The search requests a public local index. Worksheet entries and calculator inputs remain in the current browser page unless the reader exports them; neither tool sends those entries to a server or stores them in browser persistence.
Reviewed-provider links leave this publication and the destination has its own policies. Cloudflare hosting can process request information under its service policies and owner configuration; this edition cannot certify account-side retention settings or support-message handling. A monitored privacy/corrections contact and legal publisher identity have not been supplied, so no address is invented. Do not enter secrets or identifying account records into the public tools.
