Privacy Policy

Last updated: February 23, 2026

PowerVigil ("we", "us") is an independent macOS application. We take your privacy seriously. This policy explains what data we collect and how we use it.

Data we collect

The app itself collects zero personal data. All system monitoring data (CPU, memory, battery, processes) stays on your Mac. Nothing is sent to our servers.

Website analytics

We use Umami, a privacy-focused analytics tool. Umami does not use cookies, does not track users across sites, and does not collect personal information. It records anonymous page views and referrer data only.

Payments

Purchases are processed by LemonSqueezy (Lemon Squeezy LLC). When you purchase a license, LemonSqueezy collects your email and payment information. We only receive your email address and license key. We do not store credit card data.

LemonSqueezy acts as Merchant of Record and handles VAT/tax collection in compliance with EU regulations. See LemonSqueezy's privacy policy.

Optional telemetry

PowerVigil includes an optional, anonymous telemetry feature that is disabled by default. If you enable it in Settings, the app sends minimal data (event name, app version, macOS version) to help us understand usage patterns. No personal information is included. You can disable it at any time in Settings.

Feedback

If you choose to send feedback from within the app, your message and optionally basic system information (CPU core count, thermal state, battery percentage, RAM) are sent. You can uncheck the system info option before sending. Feedback is only sent when you explicitly click "Send".

License validation

PowerVigil Pro validates your license key via the LemonSqueezy API. This check happens at activation and periodically (approximately every 7 days). The only data transmitted is your license key and a machine identifier.

Auto-updates

PowerVigil uses Sparkle for automatic updates. Sparkle may send basic system information (macOS version, app version) when checking for updates. No personal data is included. Update checks happen via GitHub Pages.

Data storage

App preferences and usage history are stored locally on your Mac using UserDefaults and local files. We have no access to this data.

Your rights (GDPR)

If you are in the European Economic Area, you have the right to access, correct, or delete any personal data we hold. Since we only hold your email (via LemonSqueezy), you can contact us to exercise these rights.
