Privacy Policy
Last updated: May 12, 2025
The short version
We don't collect your data.
All calculations run locally in your browser. We never see your inputs, results, or any personally identifying information.
1. Information We Collect
Blucalculator does not collect or store personally identifiable information. Calculator inputs and results are processed entirely in your browser and are never transmitted to our servers. We do not require any account or login to use the Site. Standard server logs (IP address, browser type, page URL, timestamp) may be retained for up to 90 days for security and operational purposes by our hosting provider (Cloudflare Pages). These logs are not linked to individuals and are not used for tracking or marketing.
2. Cookies and Local Storage
Blucalculator uses no advertising cookies and no cross-site tracking cookies. We may use minimal browser local storage to remember your preferences within a calculator session (e.g., unit selection). No personal data is stored in local storage.
3. Third-Party Services
The Site is hosted on Cloudflare Pages. Cloudflare may process network-level data (IP addresses, request metadata) as part of providing CDN and DDoS protection services. Refer to Cloudflare's Privacy Policy for details. We do not use Google Analytics, Facebook Pixel, or any other third-party tracking or analytics services.
4. Fonts
Blucalculator serves the Inter typeface locally from its own servers. No font requests are made to Google Fonts or any other third-party font CDN.
5. Children's Privacy
Blucalculator is a general-purpose tool suitable for all ages. We do not knowingly collect any information from children under 13 and the Site does not contain content directed at children.
6. Your Rights
Because we do not collect personally identifiable information, there is no personal data for us to provide, correct, or delete on request. If you have specific concerns, please contact us.
7. Changes to This Policy
We may update this Privacy Policy from time to time. The "Last updated" date at the top of this page reflects any revisions. Continued use of the Site after changes are posted constitutes your acceptance.
