Privacy Policy
Privacy boundary
Tools run in your browser. This site does not perform live DNS queries or save domains, generated records or pasted text.
Optional analytics
Google Analytics loads only after you select Allow analytics. It receives the page path and an aggregate tool-completion event, never domains, email addresses, DNS records or pasted text. Use Privacy choices to decline or change your choice.
Tool-data journey
Generator and pasted-check inputs are processed in memory by code already delivered to the browser. They are not placed in URLs, sent to an application server or included in analytics. Clearing or closing the page removes them from the tool.
Consent and retention
Declining analytics leaves every browser-only tool usable. If allowed, analytics receives only the page path and bounded aggregate actions. The public site has no account or online enquiry database.
Privacy questions
Write to the registered office without including domains, records or message data that are not necessary. Depending on the circumstances, you may complain to the Information Commissioner's Office.
