Privacy Policy

1. The "No Data" Promise

At Fastcalc, we take your privacy incredibly seriously. Our core philosophy is simple: **We don't want your data.** Every calculation performed on this website happens locally in your browser. We do not store, see, or transmit your financial figures to our servers.

2. Information We Use

We only use essential technical information required to run the site:

• Local Storage: We use your browser's local storage to remember your cookie consent preferences and, in some cases, your tool inputs for your convenience next time you visit. This data stays on your machine.
• Analytics: We use anonymized analytics (like Google Analytics) to understand how many people use our tools. This records things like page views and browser types, but no personal identifiers or calculation results.

3. Third Parties

We may display advertisements from partners like Google AdSense to keep this service free. These third parties may use cookies to serve ads based on your prior visits to this or other websites. You can opt-out of personalized advertising in your Google account settings.

4. Security

Because we don't collect personal data, there is no database for attackers to target. We use standard HTTPS encryption to ensure your connection to our site is secure.
