Privacy Policy

This Privacy Policy describes what data is handled when you use PercentCalc.App ("the website", "we"), drawing a clear line between data handling by PercentCalc itself and by the third-party services we embed.

1. What PercentCalc Collects

PercentCalc itself collects no personal information and sets no cookies. All calculations run entirely in your browser; the numbers you enter never leave your device. We do not operate a backend, we do not store inputs or results, and we do not log any user-identifying data.

2. Third-Party Services

PercentCalc embeds Google Analytics, a service provided by Google. Google Analytics sets its own cookies and collects information including your IP address and behavioural data (pages visited, referrer, approximate location, time on site, etc.) on Google's servers. We use Google's aggregated reports to understand site traffic. The collection and processing of this data is governed by Google's privacy policy and their partner-sites data-usage page.

You can opt out of Google Analytics by:

• Installing Google's Analytics Opt-out Browser Add-on.
• Using a privacy-focused browser or extension that blocks analytics scripts.
• Enabling tracking-protection or "Do Not Track" features in your browser.

3. Changes to This Policy

We may update this privacy policy from time to time. Material changes will be reflected on this page; please re-check it periodically.
