Your privacy, plainly.

Amounts and inputs

Calculations run on your device in your browser. Entered amounts and tax rates are not sent to a server, and we do not keep a calculation history. No account is required.

Copying, printing, and sharing

Copying a result puts it on your device clipboard at your request. Printing uses your browser. Sharing the tool includes only the page link, without your entered amount or rate. If you send a copied result elsewhere, you choose to share those details.

Storage and tracking

We do not store tool inputs. Optional measurement follows the choice described below. No active ads or session recordings.

Optional usage measurement

Only after consent do we load Google Analytics to measure page visits, acquisition, devices and tool events. Events exclude entered amounts/dates, text, files and filenames. Your choice is saved locally; Google may use measurement cookies. Decline or change your choice in Privacy settings; all tools remain available.

External sources

We may link official sources to explain calculations. Opening an external link takes you to another site with its own privacy policy. Calculator inputs are not sent to it.
