Privacy Policy

1. Information We Collect

• Account Information: When you sign up, we collect your email address and name via Supabase for authentication.
• Anonymous Analytics: With your opt-in consent, the browser extension collects non-personally identifiable usage events via PostHog (e.g., feature usage counts and whether subtitles loaded successfully). These events are tied only to a random, resettable device identifier. We never collect your subtitle text, audio, or the URLs of the pages you watch, and you can withdraw consent at any time from the extension menu. Our website uses cookieless analytics (see Section 3).
• Payment Information: Financial transactions are handled by Lemon Squeezy. We do not store or process your credit card details on our servers.

2. Browser Extension Permissions

Lingather requires specific permissions to provide real-time AI transcription and translation. We adhere to the principle of least privilege:

• tabCapture / offscreen: Used solely to capture audio from the active tab for real-time transcription. Audio is processed in memory and is never recorded or stored.
• storage: Stores your preferences (e.g., target language) and your transcription history (video titles, subtitle text, and translations) locally on your device. You can clear this at any time from the history panel.
• scripting / activeTab: Allows the display of the subtitle overlay on the specific video page you are watching.
• tabs: Lets the extension detect when you switch between videos or tabs so subtitles are routed to the tab you are watching. We do not read or store your browsing history.
• identity: Manages your pro subscription status securely via Google Sign-In.

3. Third-Party Services & Privacy

We use a limited number of trusted partners to ensure the Service's performance and security:

• Cloudflare Web Analytics: Used for Real User Monitoring (RUM) to ensure the "instant-load" performance of our site. It is privacy-focused and cookieless.
• Umami Analytics: A self-hosted, anonymous analytics tool used to track feature conversion without tracking individual users.
• PostHog (Product Analytics): Powers the browser extension's opt-in, anonymous usage analytics. It is configured to minimize data collection and to discard IP-based geolocation. No personal data is sold or used to train third-party models.
• AI Processing: Speech recognition and translation run entirely on your device using on-device AI models (WebAssembly and the browser's built-in translator). Your audio is never uploaded to or stored on our servers, and no user data is used to train third-party models.
• Lemon Squeezy: Acts as our Merchant of Record for global tax compliance and secure payment processing.

4. Privacy & Cookie Usage

Lingather prioritizes your privacy. We do not use persistent tracking cookies, advertising IDs, or cross-site tracking technologies.

We use essential local storage or secure tokens strictly for authentication (via Supabase and Google OAuth) and to maintain your active session. These are necessary for the Service to function and are not used for marketing purposes.

5. Data Retention & Deletion

We retain account data only as long as your account is active. You may request full deletion of your account and all associated data at any time. Upon deletion, all records in Supabase and Lemon Squeezy (subscription link) will be anonymized or removed, subject to legal financial record requirements.

6. Your Rights (GDPR/CCPA)

Regardless of your location, we respect your right to access, correct, or delete your data. European (EEA) users have rights under GDPR, and California users under CCPA. For any data-related requests, please contact us at: lingather@rockhammerlabs.com.
