What happens on your device
Calculations, conversions and file processing run in your browser. Values you type and files you open are not sent to CalcPark. Some tools can remember your settings or progress (for example game statistics or a timer preset) in your browser's local storage; that data stays in your browser and you can clear it through your browser settings.
Engines downloaded from CDNs
A few file tools fetch their processing engine (such as FFmpeg, an OCR model or an image decoder) from a public content delivery network the first time you use them. That request transfers the engine to you; it does not transfer your file to anyone. The CDN sees a normal web request (your IP address and browser details), as with any script on the web.
Hosting logs
Our hosting provider keeps standard, short-lived access logs (requested page, time, IP address, browser) for security and reliability. These logs are not used to profile visitors.
Statistics and ads (only with your consent)
If measurement or advertising is enabled on this site, a banner asks for your permission before anything loads. Until you choose "Allow", no Google Analytics or Google AdSense script is loaded and no cookies from them are set. If you allow it, Google Analytics 4 records anonymous usage events (which tool was opened, whether a calculation or export succeeded) - never the values you entered or the files you used - and Google AdSense may show ads. You can withdraw consent at any time with "Privacy settings" in the footer. Google's own processing is described in Google's privacy policy.
Shareable links
Some tools offer a link that reproduces the current settings. Those settings are stored in the part of the link after the # sign, which browsers do not send to servers. Do not share such a link if it contains data you consider private.
Your rights and contact
Because we do not hold personal data about you beyond hosting logs, there is normally nothing to export or delete. For any privacy question write to kolma.kornel@gmail.com.
