What the connection checker sends, what it stores, and what stays in your browser. Written so you can actually read it.
Data Collection
There is no account and no personal identifier attached to a diagnostic. The connection tests run inside your browser and send the probe requests needed to measure reachability, timing, and public service status. Nothing else.
Website Analytics
This site uses Plausible for aggregate analytics. No personal identifiers, no cross-site tracking, no cookies. We do not send names, email addresses, or full diagnostic payloads to analytics.
Diagnostics
Browser diagnostics are best-effort. Numbers will vary by network, location, and device. The results in the check interface are meant for quick troubleshooting, not a guarantee of service quality. The share summary leaves public IP and ASN details out unless you tick the box to include them.
Third-Party Services
Reachability checks may contact public destinations such as Google, Cloudflare, and GitHub from your browser. Service-status panels read public Cloudflare and GitHub status APIs. If configured, public IP and ISP context comes from IPinfo Lite. We rely on Apple's App Store infrastructure for distribution and crash reporting where the app is available.

You can stop using the website or uninstall the app at any time. If you need help with privacy requests, contact us using the address below.
