Privacy Policy

Last updated: March 2026

SiteWatch is a self-hosted uptime monitoring tool built by ZeroDeps. We take your privacy seriously. Here's exactly what data the extension handles and where it goes.

What data does the extension collect?

The SiteWatch Chrome extension stores the following in Chrome's sync storage (local to your browser and Google account):

• Your server URL (the address of your self-hosted monitoring server)
• Your authentication token
• Your license key (if you have a Pro subscription)

That's it. The extension does not collect, store, or transmit any other personal data.

Where does data go?

The extension communicates exclusively with the server URL you configure. This is a server you own and control. No data is sent to SiteWatch, ZeroDeps, analytics services, ad networks, or any third party.

What does the monitoring server store?

The self-hosted SiteWatch server stores:

• URLs you choose to monitor
• HTTP status codes and response times from those URLs
• Timestamps of checks
• Your account plan and license key (if Pro)

This data is stored as JSON files on your server's filesystem. It never leaves your server unless you choose to share it.

Website analytics

The SiteWatch website (getsitewatch.dev) uses Google Analytics to understand how visitors find and use the site. Google Analytics collects anonymized usage data such as page views, referral sources, and browser type. No personally identifiable information is collected through analytics. You can opt out of Google Analytics by using a browser extension such as Google Analytics Opt-out.

Payment processing

SiteWatch Pro subscriptions are processed by Lemon Squeezy, which acts as our Merchant of Record. When you purchase a Pro license, Lemon Squeezy collects your payment information and processes the transaction. We do not have access to your full credit card details. Please refer to Lemon Squeezy's Privacy Policy for details on how they handle payment data.

Third-party services

The SiteWatch extension and self-hosted server use zero third-party analytics, tracking, or advertising services. The landing page website uses Google Analytics as described above. There are no cookies set by the extension, no tracking pixels, and no telemetry.

Chrome extension permissions explained

• alarms — Used to poll your server status every minute for badge updates
• notifications — Used to show desktop alerts when a site goes down or comes back up
• storage — Used to save your server URL, auth token, and license key in Chrome sync storage

Data retention

Extension data is stored in your Chrome sync storage and persists until you clear it via the extension's settings page. Server data is stored on your self-hosted server and persists until you delete it. We have no access to either.

Children's privacy

SiteWatch is not directed at children under the age of 13. We do not knowingly collect personal information from children.

Changes to this policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Continued use of SiteWatch after changes constitutes acceptance of the revised policy.
