CalcFactor is built with privacy as a core principle. All calculations on this site happen entirely within your browser. Any numbers, figures, or personal information you enter into our calculators are never transmitted to our servers, never stored in any database, and never shared with any third party.
Some calculators offer a "Save to This Device" button. Saved numbers are stored only in your own browser (local storage) so you don't have to re-enter them. They are never sent to us. You can delete them anytime with the "Clear Saved" button or by clearing your browser data.
If you choose to join our email list, we collect only your email address and the page you signed up from. Your calculator numbers are never included. Email addresses are stored with our email provider, Mailchimp, and used only to send CalcFactor emails such as our monthly note, rate updates and new tools. We never sell or share your email address. Every email includes an unsubscribe link, and you can ask us to delete your address at any time by writing to hello@calcfactor.com.
