What we collect
Nothing you type into a calculator and no file you open in a tool is sent to us. Calculations and file processing run in your browser and are cleared when you close the page.
No accounts
There is no sign-up. We never ask for your name, phone number or email to use a tool.
Analytics
We use Google Analytics to count visits and see which tools are popular. It records anonymous usage such as pages viewed and device type, with IP addresses anonymised. It never receives the numbers you enter or the files you open.
Third-party libraries
Some file tools load free open-source code (such as PDF and text-recognition libraries) from a public content delivery network. Your files are not sent to it. The currency converter fetches the latest exchange rates from open.er-api.com; the amount you enter is not sent.
Questions
Privacy questions can be sent to the Grievance Officer listed on the Contact page.
