<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 />

<h4>Generic Webhooks (optional)</h4>

When a monitored site changes status, a POST request with a JSON payload is sent to that URL. The data sent includes the website URL, its status, response time, and a timestamp. No personal data is transmitted. Please refer to the terms of service and privacy policy of the respective service you configure.</p>

<p>FlexiCache is a fast, full-featured and flexible caching system which will improve the performance and availability of any WordPress site.</p>
<p>It is highly configurable to allow unlimited caching rules – expiring different pages at different times, not caching some pages at all, caching multiple versions of the same page depending on browser, language, and so on.</p>
<p>FlexiCache will also work straight out of the box without any need for complex configuration.</p>
<h4>Features</h4>
<ul>
<li>Extensively configurable using user-defined conditions</li>
<li>Handling of high-traffic periods where multiple clients may simultaneously request uncached or expired items</li>
<li>Standalone mode which bypasses WordPress and third-party theme and plugin code to serve cached pages faster</li>
<li>Choice of storage engines: Filesystem, Memcache and SQLite</li>
<li>Pre-caching functionality to cache new versions of pages before the existing ones expire</li>
<li>SQLite indexing of Filesystem and Memcache stores to speed up removing specific items from the cache (automatically enabled if SQLite is available)</li>
<li>Sends appropriate HTTP cache headers to the requesting client</li>
<li>Serves files in compressed formats accepted by the requesting client</li>
<li>Compatible with WordPress MU</li>
</ul>
<h3>Upgrading FlexiCache</h3>
<p>FlexiCache stores config and cache data within the plugin directory (see plugin documentation in versions 1.2.4.2 onwards for the reason why).</p>
<p>If you upgrade the plugin using WordPress’s built-in upgrade process, the entire plugin directory will be replaced, including your config and cache data.</p>
<p>To preserve these, take a copy of the “plugins/FlexiCache/_data” directory before upgrading, and then copy it back after the upgrade is complete.</p>
<p>If you upgrade directly via SVN, this should not be required, since only the files under version control will be updated.</p>
<h3>Deactivating FlexiCache</h3>
<p>FlexiCache can be disabled via the admin interface as with any plugin, however if you are running in Standalone mode, you should remove the .htaccess modifications before deactivating the plugin.</p>
<p>For a standard WordPress install, this modification can be done via the admin interface, however it is recommended that you make this change manually, especially if using WordPress MU, where multiple sites may share the same .htaccess file.</p>
<p>Please see the documentation supplied with the plugin (accessible via WordPress’s admin interface) for more information.</p>
