TheSoul Metadata Translator · last updated 16 July 2026

This browser extension helps authorized users translate YouTube video title and description metadata into multiple languages from within YouTube Studio.

Information we process

• The video title and description you choose to translate.
• Your target language selections.
• Your Google account identity (email and domain), used only to sign you in and confirm you are an authorized user.
• The current YouTube video ID and its existing localization languages, used to read and update the requested video.

How we use it

Solely to generate translations and to authorize access. We do not use your data for advertising or profiling, and we do not sell it.

Service providers

• Google Gemini API — generates the translations; it receives the title and description text you submit.
• Google OAuth — authenticates your Google Workspace account.
• YouTube Data API — reads the selected video's metadata and saves the requested localizations through the connection stored for that channel.
• Cloudflare — hosts the backend and its per-channel credential store.

Storage and retention

Source metadata is cached locally in your browser (chrome.storage.local) on your device and is sent to our backend only when you request a translation. The backend processes each request in memory and does not store your metadata or translations. Requests may be temporarily logged for operational monitoring and reliability, and are not used for any other purpose. The backend stores each channel's OAuth refresh credential in a backend-only Cloudflare KV record keyed by YouTube channel ID; regular extension users never receive that credential.

Permissions

The extension runs only on studio.youtube.com. It uses browser "storage" to cache source metadata locally and "identity" only to request an OpenID Connect identity token for company-account authorization. The extension does not request a per-user YouTube Data API scope. The authenticated backend performs the requested YouTube API read or update with the stored connection for the current channel.

Your choices

You can clear local data by removing the extension at any time. Translation and saving start only after your explicit click. Existing localizations are skipped unless you explicitly enable overwrite. The extension never uploads audio or clicks Publish. Access is limited to authorized Google Workspace accounts.

Changes

We may update this policy; the "last updated" date above will change accordingly.
