Privacy Policy

1. Single-Purpose Audio Processing

LiveSub captures browser tab audio strictly on demand when you explicitly click "Start Live Subtitles" or press the keyboard shortcut on an active tab. Short audio slices (1.8 to 4.2 seconds) are transmitted over TLS 1.3 to our transcription endpoint solely to return real-time captions and translations. Raw audio chunks are discarded from server memory immediately upon response and are never recorded, archived, or used to train machine-learning models.

2. Data We Store

• Account Identifier: Optional email address when you link devices via 6-digit verification code.
• Usage Metering: Aggregate daily spoken seconds processed (for enforcing the 15-minute daily free tier) without page URLs.
• Phrasebook Vault: Only the specific subtitle lines you manually click "Save Line" to bookmark.
• Billing Metadata: Stripe customer and subscription identifiers processed by Stripe, Inc. LiveSub never sees or stores raw payment card numbers.

3. Chrome Web Store User Data Policy Compliance

LiveSub's use and transfer of information received from Chrome APIs adheres strictly to the Chrome Web Store Program Policies, including the Limited Use requirements. We never sell user data, never track browsing history across tabs, and never share data with advertising networks or data brokers.

4. Instant Account & Data Deletion

You may permanently erase your account, active sessions, usage counters, and saved Phrasebook Vault lines at any time via our self-serve Account Deletion page or by contacting support@guardino.ai.
