Privacy Policy

What we collect

SlickCalcs calculators run entirely in your browser. We do not require accounts and we do not collect the numbers you type into calculators.

• Analytics. We use privacy-friendly analytics (Cloudflare Web Analytics and/or Google Analytics 4) to count visits and understand which calculators are popular. This data is aggregated and never sold.
• Server logs. Our web server keeps standard logs (IP address, pages visited, timestamps) for security and debugging, retained for a limited period.

Cookies & advertising

Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this and other sites. You can opt out of personalized advertising by visiting Google Ads Settings.

If you are in the EU/UK, you will be asked for consent before advertising cookies are set, in line with GDPR requirements.
