Privacy Policy

Last updated: 5/7/2026

Overview

healthcheck is a client-side web application. All data is stored locally in your browser using localStorage. We do not collect, store, or transmit any personal information to external servers.

Data Storage

All URLs, column configurations, settings, and preferences are stored exclusively in your browser's localStorage. This data never leaves your device unless you explicitly export it.

Health Checks

When you run a health check, your browser sends requests through our server-side proxy to determine if the target URL is online. We do not log or store these requests.

Cookies

We use localStorage for application functionality. Third-party services (such as Google AdSense) may use cookies for advertising purposes.

Third-Party Services

Google AdSense may collect data according to its own privacy policy. Donation links redirect to external services (BuyMeACoffee, PayPal).
