Privacy Policy
How Calculat.dev protects your privacy, executes calculations locally, and safeguards your device data.
Calculat.dev was built with an uncompromising commitment to privacy: your calculation inputs never leave your web browser. Whether computing loan payments, tax estimates, health biomarkers, or engineering equations, all mathematical algorithms run client-side on your local device.
1. Information We Do Not Collect
Unlike traditional financial or healthcare portals, Calculat does not require account creation, logins, credit card entries, or email registrations. When using any of our calculation utilities:
- We do not intercept, transmit, or record the numeric figures you type.
- We do not build profiles of your financial standing, income, or physical health metrics.
- We do not sell or syndicate user calculation habits to data brokers, ad networks, or lenders.
2. Local Storage and Client-Side Cookies
Calculat leverages standard browser localStorage solely to provide client-side convenience features:
Recently Used Calculators
Keeps track of tool slugs you recently used so you can jump back to them quickly.
Starred Favorites
Saves your favorite tools directly within your browser for one-click access.
This data resides exclusively on your local device. It is never uploaded to any remote server and can be cleared at any time via your browser settings or our cookie preferences tray.
3. Server Logs and Diagnostic Analytics
To maintain 99.9% uptime, mitigate distributed denial-of-service (DDoS) attempts, and understand aggregate directory usage, standard non-identifiable web server logs and privacy-preserving Google Analytics (GA4) may measure page request frequencies and browser types. No personally identifiable information (PII) or numeric calculation payloads are ever attached to telemetry events.
4. Third-Party Links & External References
Certain calculator editorial guides include educational citations to authoritative bodies (e.g., Internal Revenue Service, Centers for Disease Control and Prevention, National Institute of Standards and Technology). We do not control and are not responsible for the privacy practices of external third-party websites.
5. Updates and Inquiries
Any updates to this Privacy Policy will be published immediately on this page with a revised effective date. If you have questions regarding our privacy architecture, feel free to contact us through our contact page or learn more about our student background on our about page.
