Local Computations
Every calculation runs inside your browser. The numbers you type never leave your device.
No Ads or Tracking
CalcUnit has no ads, no third-party trackers, no cookies, and no sign-up system.
1. Information We Do NOT Collect
CalcUnit works without an account. We do not log the numbers you enter, store your IP address, or create any user profile.
- We do not log or store values you enter in the inputs.
- Standard server hosting logs do not record or store user IPs.
- There is no registration system, so there is no database that can be breached.
2. Local Browser Storage & Saved Tools
If you save a calculator using the bookmark button, that preference is stored in your browser’s local storage. It stays on your device and is never sent to our servers. Clear it any time from your browser settings or the Settings page on this site.
3. Hosting & Server Log Statistics
Pages are served from a global CDN. The hosting platform collects basic, non-personal server stats (page request counts, URL paths, referral sources). This is used only to catch broken links and monitor page load times - not to track individual users.
4. Frequently Asked Questions
Is it safe to use this tool for medical or financial calculations?
Yes. Your numbers stay on your machine and are never sent anywhere. That said, treat any calculator result as a starting point, not a final answer, for medical or financial decisions. See our Disclaimer for details.
