<h4>Privacy</h4>
<p>LukStack Uptime Monitor only stores the URLs you choose to monitor and their status data. No personal information is collected or transmitted to external servers except for the webhook notifications you configure.</p>
<p>This plugin uses Freemius for license management and opt-in usage tracking. Freemius collects anonymized data only when users explicitly opt in. See the Freemius Privacy Policy: https://freemius.com/privacy/</p>
<h3>External services</h3>
<p>This plugin connects to external services as part of its core monitoring functionality. Below is a description of each service, what data is sent, and when.</p>
<h4>Monitored Websites</h4>
<p>LukStack Uptime Monitor sends HTTP requests to the website URLs you add for monitoring. This is the core functionality of the plugin and is required to check uptime and response times. An SSL connection on port 443 is also made to check the SSL certificate expiration date for HTTPS sites (Pro). These requests are sent automatically via WordPress Cron and when you manually click “Check now”. The data sent is a standard HTTP GET request with a custom user agent header. No personal data is transmitted.</p>
<h4>Freemius</h4>
<p>This plugin uses Freemius SDK for license management, usage tracking (opt-in only), and the upgrade flow. When a user opts in, anonymized data such as the site URL, WordPress version, PHP version, and plugin version may be sent to Freemius servers. Users can opt out at any time.</p>
<p>This service is provided by Freemius, Inc.<br />

<h4>Slack (optional)</h4>
<p>If you configure a Slack webhook URL in the plugin settings, LukStack Uptime Monitor sends POST requests to the Slack Incoming Webhooks API when a monitored site changes status (goes down, recovers, or has SSL issues). The data sent includes the website URL, its status, response time, and a timestamp. No personal data is transmitted.</p>
<p>This service is provided by Slack Technologies, LLC / Salesforce, Inc.<br />

<h4>Discord (optional)</h4>
<p>If you configure a Discord webhook URL in the plugin settings, LukStack Uptime Monitor sends POST requests to the Discord Webhooks API when a monitored site changes status. The data sent includes the website URL, its status, response time, and a timestamp. No personal data is transmitted.</p>
<p>This service is provided by Discord, Inc.<br />
Terms of Service: https://discord.com/terms<br />

<h3></h3>
<p>Version: 2026-04-02 — v0.9.2</p>
<ul>
<li>FIX: URLhaus (abuse.ch) integration now requires an API key (Auth-Key header); added URLhaus API Key field in Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Security scanning. Without a key the URLhaus check is skipped gracefully.</li>
