We respect your privacy. This page explains exactly what we do — and don't — with your data.
What we collect
Nothing you type into a calculator leaves your browser. All computation happens locally on your device. Inputs and results are never transmitted to our servers.
We do collect:
- Anonymous traffic analytics — only if you accept the analytics cookie. Counts page views and locale popularity. No personal identifiers, no cross-site tracking.
- Advertising cookies — only if you accept the ads cookie. Used by Google AdSense to show relevant ads.
- Essential cookies — your theme preference (light/dark/auto) and your consent choice. Never optional; the site can't function without them.
Cookie banner
You see a banner on your first visit. You can accept all, reject all, or customize. Your choice is stored for 30 days, then re-asked.
Third parties
When you accept advertising:
- Google AdSense may set cookies and read your IP address. See Google's Privacy Policy.
We don't use Facebook Pixel, TikTok, Hotjar, or any social-media tracker.
Your rights (GDPR / CCPA)
You can:
- Withdraw consent any time via the cookie banner (a "Reset cookies" link in the footer will appear after consent)
- Request what data we have about you — though, since we collect no personal data, the answer is usually "none"
- Request deletion of analytics data tied to your session
Email m.serdar.karaman@gmail.com with any privacy request.
Children
This site is not directed at children under 13. We don't knowingly collect data from anyone under 13.
Changes
If we change this policy, we'll re-show the cookie banner with a clearly marked version bump so you can re-review your choices.
