Common questions
Will it slow my site down?
Scans run in small background batches through WP-Cron instead of during visitors' page loads, and you can lower the batch size in Settings.
What's the difference between Free and Pro?
Free scans weekly, up to 500 URLs. Pro adds daily scans, unlimited URLs, email alerts and CSV export.
Is it a subscription?
Pro is $59 per site per year and renews annually. Cancel any time; the plugin falls back to the free tier.
What data leaves my site?
The plugin requests the URLs found in your content to check them, and requests your own site for security checks. When you activate a key, the key and your site's host name are sent to Lemon Squeezy to validate it.
What happens on uninstall?
Deleting the plugin removes its table, options, transients and scheduled events. Deactivating keeps your results.
Is this a security audit?
No. It flags common misconfigurations. It is not a penetration test or a guarantee of security.
