Privacy Policy

Calc Tools is built around a simple promise: your files never leave your device. Every conversion, edit and calculation happens locally in your web browser using JavaScript and WebAssembly. We do not upload, store, or transmit the content you process.

What we collect

We do not require accounts and we do not collect the files you use with our tools. We may collect anonymous, aggregated usage analytics (such as page views) to improve the site.

Analytics

We use Google Analytics 4 to understand which pages and tools are used, for example page views, the tool you open, whether a tool was used or produced a download, your approximate country, device type and browser. It never receives the files, text or values you enter into a tool. Google Analytics sets first-party cookies (_ga, _ga_*) that are shared across our sites and kept for up to 2 years. If you are in the EEA, the UK or Switzerland, these cookies are only set after you give consent; otherwise Google receives only cookieless, aggregated signals.

You can change your consent at any time via the "Privacy and cookie settings" link of our consent banner, or opt out with the Google Analytics opt-out add-on. See how Google uses information from sites that use its services.

Cookies & advertising

We may display ads served by Google AdSense and other partners. These partners may use cookies to serve ads based on your prior visits. You can opt out of personalised advertising via Google Ads Settings.
