Calculator inputs
Calculators execute in your browser. No account is required. Share URLs contain only the numeric inputs you choose to place in the URL.
Operational data
Standard hosting security logs may include request time, page, browser and network information. Aggregate analytics may measure page performance and calculator completion.
Sensitive information
Do not enter names, account numbers, Social Security numbers, tax identifiers, credentials, full card numbers or confidential records. The service is not designed to receive them.
Contact
Privacy questions may be sent through the contact form at https://freecalculatorsonline.com/contact. This policy should be reviewed with final analytics, advertising and entity details before a custom-domain commercial launch.
Calculations run in your browser
Calculator inputs are processed on your device. Entering numbers into a calculator does not transmit them to a server. There is no account, profile or saved history holding them. Closing the page discards them.
What never to enter
Do not enter account numbers, government identifiers, credentials or any other sensitive identifier into a calculator field. No calculation on this site requires them, and a share link would carry them into a URL.
Third parties and this policy's status
This policy should be reviewed alongside final analytics, hosting and any advertising arrangements before a commercial launch on a custom domain, and updated to describe what is actually in place at that point. It describes the calculator behaviour above, which is a property of how the site is built instead of a vendor arrangement.
Analytics and measurement
Any analytics used is limited to aggregate measurement of which pages are read and how people arrive, and is not used to build a profile of an individual or to target advertising. Before a commercial launch this section will be updated to name the specific provider in use and describe its retention, because a privacy policy that does not name what is actually running is not a policy.
Your rights and how to exercise them
Because the site holds no account and no profile, there is generally no stored personal record to access, correct or erase. Where any question arises about data held, it can be raised through the privacy contact, and a response will describe what exists , not restating the policy.
