Privacy Policy
Short version: we collect no personal data and use no cookies.
What We Do Not Collect
cupstogramscalculator.com does not:
- Use cookies of any kind
- Collect your name, email address, or any personally identifiable information
- Track your conversions or search history
- Store any data you enter into calculators (all calculations happen in your browser)
- Use advertising networks or ad tracking pixels
- Use Google Analytics, Facebook Pixel, or similar behavioral tracking tools
- Sell or share any data with third parties
- Require registration or account creation
Analytics
We use Cloudflare Web Analytics to understand aggregate traffic patterns. Cloudflare Web Analytics is privacy-preserving by design:
- No cookies are set on your device
- No personal data is collected
- No cross-site tracking occurs
- IP addresses are not stored
- Only aggregate, anonymous metrics are reported (page views, referrers, browser types)
You can read more about Cloudflare Web Analytics' privacy approach at cloudflare.com/web-analytics.
How Calculators Work
All calculation logic runs entirely in your browser using JavaScript. When you enter values into a calculator, those values are never sent to our servers. The results are computed locally on your device. No conversion data is stored, logged, or transmitted.
Hosting and Infrastructure
This site is hosted on Cloudflare Pages. Cloudflare may process standard web server log data (IP addresses, request timestamps, user agents) as part of delivering the site to you. This processing is governed by Cloudflare's Privacy Policy. We do not have access to individual-level server log data.
Your Rights
Because we collect no personal data, there is nothing to access, correct, or delete. If you have questions about privacy on this site, you are welcome to contact us through the information available on this site.
Changes to This Policy
We may update this privacy policy if our practices change. Any changes will be posted on this page. We will never introduce personal data collection or cookies without updating this policy and noting the change prominently.
