Privacy Policy

What we collect

We collect anonymous usage statistics through Plausible Analytics — a privacy-friendly analytics provider that does not use cookies and does not track individuals across sites. This includes page views and tool usage events (without any personal data).

If you submit feedback through a tool page, we store your rating and optional comment in our database. No email address or identifying information is collected with feedback.

What we do not collect

All tool processing happens entirely in your browser. Text you paste into JSON Formatter, Diff Checker, Regex Tester, or the QR Code Generator is never sent to our servers. Your financial inputs in the Mortgage Calculator and Compound Interest Calculator are computed locally and never transmitted.

Analytics

We use Plausible Analytics which is GDPR, CCPA, and PECR compliant. It does not use cookies, does not collect personal data, and does not require a cookie consent banner. You can view their data policy at plausible.io/privacy.

Advertising

We may display advertisements through Google AdSense. AdSense uses cookies to serve relevant ads. You can opt out of personalized advertising through Google Ads Settings.

Feedback data

Feedback you submit (star ratings and comments) is stored in a database to help us improve our tools. We do not associate feedback with any personally identifiable information. Feedback data is never sold or shared with third parties.

Contact

If you have questions about this privacy policy, please open an issue on our GitHub repository or contact us through the feedback form on any tool page.
