Privacy policy

Your PC's data stays on your PC. Here's exactly what that means.

Last updated October 12, 2026

In short

Know My PC is built to keep your information on your PC. It has no account system and no analytics, and it doesn't sell or share data. This policy explains the few things that do leave your PC.

The app

What stays on your PC. Know My PC reads information about running processes, memory, drives, startup items, services, scheduled tasks, installed apps and network ports so it can explain what's slowing your PC down. It stores your settings and a history of slowdowns in %LOCALAPPDATA%\Know My PC. None of this is sent anywhere. You can export or delete it from Settings.

License checks. When you activate a license, the app sends your license key and your PC's name (so you can tell your PCs apart in the customer portal) to Polar, our payment provider. About once a week it sends the key again to confirm it's still valid. No other information about your PC is included.

Local connections. To show which AI models are loaded, the app asks Ollama and LM Studio on your own PC (localhost). These requests never leave your PC.

Notifications. Overload alerts are Windows notifications created on your PC.

Purchases

Payments are handled by Polar Software, Inc. as merchant of record. Polar collects your email, payment and billing details to process the order, issue your license key and handle taxes. We receive your email address and order details from Polar to provide support. We never see your full card number. Polar's privacy policy is at polar.sh/legal/privacy.

This website

This site has no cookies, analytics or trackers. It's hosted on GitHub Pages, which may log your IP address for security and operations; see GitHub's privacy statement.

Support email

If you email us, we use your message and address only to help you, and we keep it as long as needed to support your purchase.

Your choices

You can delete the app's data anytime by clearing history in Settings or deleting the folder above. To access or delete purchase information, email support@knowmypc.app and we'll handle it with Polar.

Changes

If this policy changes, we'll update the date at the top. Questions: support@knowmypc.app.
