Your choices and rights

You can use public calculators without creating an account. If you create one, you can review the information attached to it and request account deletion from the user area. Saved calculations remain under your control: use Save project when you want storage, and remove projects that are no longer needed. Essential session cookies support sign-in and security; they are not used for advertising.
