How We Build Pages
Every utility must work before it is published. We add clear inputs, complete task-specific results, limitations, examples, original explanations, responsive design, and automated tests. Approximate information, such as IP geolocation, is labelled as approximate.
Data and Privacy
Published IP location and network lookups use licensed reference databases stored with our application. Embedded maps and Google Analytics remain third-party services. Our Privacy Policy explains the current data practices and service providers.
