Most of our tools can be used without creating an account or providing personal information.

may be processed locally by your browser.

However, certain tools or features may require information to be sent to our servers or third-party services in order to provide the requested functionality. Where this occurs, the relevant information may be processed as necessary to provide that feature.

Third-party advertising companies operate according to their own privacy policies. BestCalculator does not control how third-party advertising services process information.
