Privacy

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.

External services

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.

Monitored Websites

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. These requests are sent automatically every 5 minutes (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.

Slack (optional)

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.

Discord (optional)

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.

Generic Webhooks (optional)

You may configure any third-party webhook URL (e.g. Microsoft Teams, Zapier, Make, or a custom endpoint). 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.
