Privacy Policy

Effective Date: May 2, 2026

This Privacy Policy describes how your personal information is collected, used, and shared when you use Lid (the "App").

1. Information We Collect

Information You Provide

• License Key: When you purchase a license, you may enter a license key to unlock premium features.
• Email Address (optional): You may provide an email address during license activation for verification purposes.

Information Collected Automatically

• Lid Sensor Data: The App reads your MacBook's lid angle sensor to trigger automation rules. This data is processed locally on your device and is never transmitted to our servers or third parties.
• App Context Data: The App monitors which applications are currently running to enforce app-specific automation rules. This information is processed locally and never leaves your device.
• Machine Fingerprint: A cryptographic hash of your Mac's hardware identifiers is generated locally to prevent license sharing. This fingerprint cannot be used to identify you personally.

Information Stored on Your Device

• User Preferences: Your settings, automation rules, and shortcuts are stored locally in your Mac's UserDefaults.
• License Credentials: Your license key, instance ID, and signed entitlement certificate are stored securely in your Mac's Keychain.

2. How We Use Your Information

We use the information we collect to:

• Provide and maintain the App's core functionality (lid angle monitoring and automation)
• Validate and manage your software license
• Prevent fraud and unauthorized license sharing
• Improve the App's performance and reliability

3. Third-Party Services

LemonSqueezy

We use LemonSqueezy (a service provided by LemonSqueezy, LLC) to process payments and manage software licenses. When you activate or validate a license:

• Your license key and machine fingerprint are sent to LemonSqueezy's servers (api.lemonsqueezy.com)
• LemonSqueezy may collect your email address if provided during purchase
• Your use of LemonSqueezy is subject to their Privacy Policy

We do not store your payment information (credit card details, etc.) on our servers. All payment processing is handled directly by LemonSqueezy.

4. Data Storage and Security

• Local-First Architecture: The App is designed with a privacy-first approach. All automation data, sensor readings, and app context information are processed and stored locally on your device.
• Keychain Storage: Sensitive license credentials are stored in Apple's secure Keychain.
• No Telemetry: The App does not include analytics, tracking, or telemetry. We do not monitor how you use the App.
• No Network Calls for Core Features: The App does not require an internet connection for its core functionality. Network requests are only made to LemonSqueezy's servers for license validation.

5. Data Retention

• License Data: We retain your license validation records on LemonSqueezy's servers as long as your license is active or as required by law.
• Local Data: All locally stored data remains on your device until you uninstall the App or delete the data manually.
• Deactivation: When you deactivate your license, your instance is removed from LemonSqueezy's systems, though they may retain purchase records for accounting purposes.

6. Your Rights

Depending on your location, you may have the following rights regarding your personal data:

• Access: Request a copy of the personal data we hold about you.
• Correction: Request that we correct inaccurate or incomplete data.
• Deletion: Request that we delete your personal data (note that this may deactivate your license).
• Portability: Request a copy of your data in a structured, machine-readable format.
• Objection: Object to the processing of your data for specific purposes.

7. Children's Privacy

The App is not intended for use by children under the age of 13 (or the applicable age in your jurisdiction). We do not knowingly collect personal information from children.

8. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on our website or within the App. Changes are effective when posted.
