PRIVACY BOUNDARIES

Privacy Policy

We process data only to the minimum extent each feature requires, with a clear distinction between local tools and network queries.

Local tools

Local tools such as Base64, JSON, passwords, hashes, and regular expressions do not intentionally send tool inputs to this site’s servers.

Network and DNS queries

Network checks, DNS queries, and domain diagnostics send only the parameters needed for the query through POST requests. Domain-diagnostic POST request bodies are not logged by this application.

Independent IPv4 / IPv6 probes

The network check requests api.ipify.org and api6.ipify.org separately to confirm whether the browser can connect over IPv4 and IPv6. These services receive the public address and connection metadata normally included in a network request; results are not stored in browser storage.

Hosting and operational metrics

This site is hosted by EdgeOne. Its security and operational logs may contain the request IP, path, and ref source parameter. Log retention depends on the EdgeOne console configuration and must be confirmed there for the deployed site. We do not embed third-party visitor analytics scripts.

Browser storage

This site uses only necessary local or session storage for language preferences, interface state, and the session dismissal state of mobile ads.

Advertising

Until advertising is configured, the site does not load ad-provider scripts or create advertising cookies. If ads are added, this policy and any required consent mechanism will be updated at the same time.

Policy updates

When features or service providers change, this page will be updated with the new processing boundaries and date.
