Privacy Policy
Last updated: February 2026
Your privacy matters to us. CalcAtlas is designed to be privacy-first: we collect as little data as possible and keep what we do collect strictly anonymous.
Information we collect
CalcAtlas does not require you to create an account or provide any personal information to use our calculators. All calculations are performed entirely within your browser — no data you enter into any calculator is sent to or stored on our servers. We may collect basic, anonymous usage data through Vercel Analytics, including pages visited and general traffic patterns. This data is aggregated and cannot be used to identify individual users.
Cookies and local storage
We use your browser's localStorage solely to remember your preferred theme (light or dark mode). This data never leaves your device and is not accessible to us. We do not use advertising cookies, tracking pixels, or third-party analytics platforms that build individual user profiles.
How we use information
The anonymous analytics data we collect is used only to understand which calculators are most useful, so we can improve the site. We do not sell, share, or otherwise disclose any data to third parties for marketing or advertising purposes.
Third-party services
CalcAtlas is hosted on Vercel. By using our site, you are also subject to Vercel's privacy policy. We do not embed third-party advertising networks, social media trackers, or any other external services that may track you.
Children's privacy
CalcAtlas is a general-purpose tool suitable for all ages. We do not knowingly collect any personal information from children under 13. If you believe a child has submitted personal information to us, please contact us and we will promptly delete it.
Changes to this policy
We may update this Privacy Policy from time to time. When we do, we will revise the "last updated" date at the top of this page. Continued use of CalcAtlas after changes constitutes your acceptance of the updated policy.
