book-video uploader
book-video uploader is an internal desktop tool that Sunimori Studio uses to publish its own videos to its own YouTube channels through the YouTube Data API. It is operated only by Sunimori Studio, on our own computer, and is not offered to or used by the public. It runs only when we start it.
What it accesses
When the channel owner signs in with Google and grants permission (OAuth scope https://www.googleapis.com/auth/youtube.force-ssl), the tool uses that access only to:
- read the authorized channel's ID, title and handle, to confirm it is uploading to the correct channel;
- upload our videos and set their title, description, tags, category, language, audience and AI-disclosure settings, publishing status and translated titles;
- set custom thumbnails, upload caption files, and create playlists and add our videos to them;
- read the processing and privacy status of videos it has uploaded.
It does not read, collect or store comments, messages, viewing history, analytics, subscriber lists or any information about other YouTube users.
How information is stored
- The OAuth refresh token is stored only on the channel owner's computer, in a file readable only by that user account. It is never sent to Sunimori Studio's servers or to anyone else.
- The tool keeps a local log of what it uploaded (video IDs, links, publishing status and which steps were completed) for our own bookkeeping.
- The video files, thumbnails, captions and texts it sends to YouTube are our own content.
Sharing and use
We do not sell, rent or share information obtained through Google APIs, and we do not use it for advertising or to train artificial intelligence or machine learning models. The tool sends data only to Google (YouTube) in order to perform the actions listed above.
book-video uploader's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
YouTube API Services
book-video uploader uses YouTube API Services. Use of YouTube is subject to the YouTube Terms of Service, and Google's handling of information is described in the Google Privacy Policy.
Retention and revoking access
- The token is kept until access is revoked or the token file is deleted; the upload log is kept as long as we need it to manage our channels.
- Access can be revoked at any time on the Google Account third-party access page. After that the tool can no longer access the channel.
Changes
If this policy changes, we will update this page and the date above.
