Shadow Mastery, by Innovations Mastery. Last updated October 3, 2026.
Shadow Mastery is the private production tool of two channels run by the same owner: Innovations Mastery, on business history, and ArchiDeck, on Morocco's architecture and history, in French. It makes short videos from scripts and is used by the channels' own team.
Google sign-in
Signing in with Google gives the app your name, email address and profile picture, used only to identify your account.
Google Drive
When the channel owner connects Google Drive, the app asks only for the drive.file permission: it can create and update the video files it uploads itself, into the folders the owner chose, and cannot see or change any other file in the Drive. It uploads a video only when someone presses “Upload to Drive”. The access token is stored on the app's server, is never shared, and can be revoked at any time from the Google account (Security → Third-party connections).
Instagram and Facebook comments
The app reads the comments people leave on the channels' own Instagram and Facebook posts, through Meta's official APIs. It uses them only to suggest and publish the channel's replies: an AI model drafts a suggestion and the owner reviews it before it is published. Comments are never sold or shared, never used for advertising or to train AI models, and the app builds no profile of the people who write them. To have your comments' data deleted, see data deletion.
YouTube comments
The app uses YouTube API Services to read the comments on the channels' own YouTube videos and to publish the channel's replies, under the same rules as above. By using it you agree to theYouTube Terms of Service, and Google's use of the data is covered by the Google Privacy Policy. Data from YouTube is refreshed or deleted within 30 days. Access can be revoked at any time atsecurity.google.com/settings/security/permissions.
What we don't do
We don't sell or share Google user data, use it for advertising, or use it to train AI models. Data from Google APIs is used only to provide the features above.
