What to know
Browser tools do not transmit inputs or outputs. IP lookup contacts ipify directly to check the public address. Postal and currency lookups contact the provider shown in the interface. Analytics records only the tool name and public page visits, never inputs, results, filenames, queries, notes or IP fields. DNT/GPC are respected.
