We will keep this simple because we think privacy policies should actually be readable.
We do not need your personal information. You do not create an account, enter your name, or share anything personal to use our calculators. All calculations happen right in your browser.
We do look at basic analytics. We use tools like Google Analytics to understand things like which calculators people use most and what devices they are on. This helps us improve the site. None of this data identifies you personally.
We use cookies. Cookies help the site run properly and help us understand how people navigate it. You can turn cookies off in your browser settings if you prefer — though a small number of features may not work perfectly without them.
We do not sell your data. Ever. We have no interest in it and no reason to.
Third-party services. We may use Google Analytics and advertising partners. These services operate under their own privacy policies, which are worth reading if you are curious.
