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.
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/
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 (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.
Freemius
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.

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.

Συχνές Ερωτήσεις
-
How many websites can I monitor?
-
The free version supports up to 2 websites. The Pro plan supports up to 100 websites.
-
How often are websites checked?
-
The free plan checks every 15 minutes. The Pro plan checks every 5 minutes for faster downtime detection.
-
Can I monitor SSL certificates?
-
SSL certificate monitoring is available in the Pro plan. You will receive warnings when a certificate is within 30 days of expiring, with critical alerts at 7 days.
-
Why does my site show as DOWN when it is actually online?
-
This can happen if:
- Your site blocks automated requests or specific user agents
- A firewall or security plugin is blocking the monitoring server
- The site requires authentication
- There are geographic restrictions
Try adding your monitoring server IP to any whitelist or firewall rules.
-
Will this slow down my WordPress site?
-
No. The monitoring checks run in the background via WordPress Cron and do not affect your site frontend performance.
-
Can I monitor non-WordPress sites?
-
Yes. LukStack Uptime Monitor can monitor any publicly accessible website, regardless of the platform.
-
How do I set up Slack notifications?
-
- Create an Incoming Webhook in your Slack workspace
- Copy the webhook URL
- Paste it into LukStack > Settings > Webhook URL
- Click “Send Test Notification” to verify
-
How do I set up Discord notifications?
-
- Go to your Discord server settings
- Navigate to Integrations > Webhooks
- Create a new webhook and copy the URL
- Paste it into LukStack > Settings > Webhook URL
-
Why are automatic checks not running?
-
WordPress Cron only runs when someone visits your site. If your site has low traffic, checks may be delayed. For reliable monitoring, set up a real server cron job. See the Help page in the plugin for instructions.
-
Can I monitor localhost or internal sites?
-
No. For security reasons, localhost (127.0.0.1) and private IP ranges are blocked from monitoring.
-
Does this plugin send any data externally?
-
The plugin makes outbound requests to:
- The websites you choose to monitor (to check their status)
- Your configured webhook URL (to send notifications)
- Freemius servers for license management (opt-in only)
No data is sent to the plugin developer directly.
