Privacy Policy
Last updated: November 2026 • Effective immediately
Our Core Promise: Your Media Stays Yours
At SinSub Studio, we respect creative copyright and individual privacy. We operate on a foundational architecture where subtitle files never touch permanent disk storage. You retain 100% ownership of all uploaded and translated content.
1. Zero Subtitle Retention Policy
All subtitle files (.SRT, .VTT) and dialogue texts uploaded to SinSub Studio are held exclusively in ephemeral volatile RAM (memory) during the translation request. As soon as the translated chunk is returned to your browser, it is instantly purged from server memory. We do not store, archive, log, or sell any of your subtitle dialogues.
2. No AI Model Training On Your Content
Your film dialogues, scripts, and subtitle files are never used to train, retrain, or improve foundational AI models. Requests are dispatched through Google GenAI API with enterprise zero-retention privacy flags enabled.
3. Google Sign-In & User Identity
Authentication is handled securely via Google OAuth 2.0. We only read your public profile information (Display Name, Email Address, and Avatar Photo) to personalize your workspace session. We never access your Google Drive, contacts, private emails, or browsing history.
4. Gemini API Key Security
If you choose to input your personal Gemini API key in Settings, it is stored strictly within your browser's local storage (localStorage). It is never written to remote cloud databases, never shared with third parties, and transmitted solely over encrypted HTTPS (TLS 1.3) directly to the inference endpoint.
5. Cookies & Tracking
SinSub Studio does not use intrusive third-party cross-site tracking cookies. We only utilize essential local storage keys necessary for keeping your active studio session and theme preferences intact.
