Existing Agency customers keep their current access. PRIVACY For ordinary find-and-replace edits, the extension communicates directly with YouTube using an authorization token stored on your device. AI features are an exception: when you request an AI rewrite or translation, the selected video's title and description, together with your instructions, pass through our servers to Lovable's AI gateway and Google's Gemini model service. For AI chapter generation, the video's title, transcript, and duration are processed. AI requests use text, not your video or audio files. Avoid including sensitive information in AI requests. AI requests and responses may be retained in service-provider logs under the applicable provider terms and settings.
