We simply don't store your data. Or send it anywhere.
The OnTheScales app collects no personally-identifiable information whatever. We don't know your name, your phone number, where you are, or anything else about you. It's that simple. All conversions are done inside the application itself with no connection to outside servers, or any other third party.
