Shumar does not have an account system or a server-side database. The values you enter into the unit converter and tax calculator stay in your browser and are never sent to our servers. Your language preference is saved locally in your browser so it's remembered on your next visit.
We use Google Analytics to understand aggregate usage of the site, such as which pages are visited. This data is not tied to the values you enter into the converter or calculator.
