Dubtitles Privacy Policy

Dubtitles is a browser extension that translates Netflix subtitles and manages licensing. This policy explains what data we collect, how we use it, and your choices.

Data We Collect

• License data: License key, plan type, expiration, and backend verification timestamps used to confirm access.
• Device identifier: A pseudonymous device ID generated locally to reduce fraud and enforce license limits.
• Usage metrics: Monthly minutes used and session timestamps to enforce the free-tier quota.
• Diagnostics: Minimal error messages related to license verification; console debug logging is disabled in production builds.
• Payment: Payments are processed by Stripe on our server-side checkout. Card data is handled by Stripe, not the extension.

How We Use Data

• Validate licenses and enforce plan limits.
• Detect abuse (e.g., tampering or time manipulation) and protect the service.
• Provide usage info in the popup UI (free minutes remaining, next reset date).

Where Data Is Stored

• Locally (extension): License state, usage counters, and device ID are stored in browser localStorage and mirrored to chrome.storage.local for UI rendering.
• Server: License verification sends license key, device ID, timestamp, build ID, and optional signed assertion to the Dubtitles license API (LICENSE_API_URL).
• Third parties: Subtitle text that requires translation is sent to Google Translate (translate.googleapis.com) to provide translations.

What We Do Not Collect

• No browsing history or information about which titles you watch.
• No selling or sharing of data with data brokers or advertisers.

Permissions Explained

• tabs / activeTab / scripting: Inject translation scripts only on Netflix watch pages to render translated subtitles.
• storage: Store license and usage data locally.
• Host permissions: https://www.netflix.com/* (inject translation scripts) and https://translate.googleapis.com/* (perform translations).

Retention

License and usage data are kept while your license is active; usage counters reset monthly. Server-side license records are retained as needed for billing, fraud prevention, and compliance.

Your Choices

• Revoke the local license from the extension UI or remove the extension to delete local data.
• To request deletion of server-side license data (where applicable), contact us using the channel below.
