At Precise Calcs (“we”, “us”, or “our”), your privacy is important. This Privacy Policy explains what information we collect, how we use it, and your rights regarding that information when you visit our website precisecalcs.com (the “Site”). Our core mission is to provide accurate, client‑side calculation tools – we do not sell your data or store your calculation inputs.
1. Information We Collect

b. Cookies and Similar Technologies
We use minimal cookies to improve your experience:

You can disable cookies via your browser settings, but some features may become less convenient.
c. Information You Voluntarily Provide
Precise Calcs does not require registration. We do not collect names, emails, or payment information unless you explicitly contact us (e.g., via a feedback form). Any numbers you enter into our calculators are processed entirely in your browser – they are never sent to our server or stored.

- To respond to your questions or feedback if you contact us.
- To display non‑personalised advertisements (if we add ads in the future).
3. Third-Party Services
We may use the following trusted third‑party tools. Each has its own privacy policy:
- Google Analytics – tracks site usage. Google Privacy Policy
- Hosting provider (e.g., Vercel, Netlify, or similar) – stores server logs for security.
- Ad networks (if applicable) – may use cookies for interest‑based ads. You can opt out via YourAdChoices.
We do not share your personal data with any other third parties unless required by law.
4. Data Retention
Server logs are retained for a maximum of 30 days, then anonymised or deleted. Analytics data is aggregated and retained according to Google’s policies. No calculator input data is ever stored.
