Privacy policy

why-studio uses YouTube API Services to publish and manage videos for まいにちのなぜ. Google’s handling of data is described in the Google Privacy Policy.

Data access and use

When the channel owner grants access, why-studio receives Google OAuth access and refresh tokens. It reads the channel name and ID to check that the correct channel authorized the tool. It reads video, caption and playlist details to publish, update and verify episodes. It sends video files, captions, thumbnails and their metadata to YouTube when the channel owner runs publishing commands.

Storage and sharing

The publishing tool stores OAuth tokens in a file restricted to the publishing computer’s user account. It keeps publication records such as YouTube video, caption and playlist identifiers alongside the episode files so the owner can update existing uploads. It sends authorized data to Google for OAuth and YouTube API requests. The tool uses Google user data only for publishing and verifying channel content, and follows Google’s Limited Use requirements.

Cloudflare hosts these information pages. The pages have no sign-in or data submission forms.

You can revoke why-studio’s access at any time from Google Account permissions. Contact info@kanun.co.jp to request deletion of locally stored authorized data or to ask about privacy. The operator removes stored tokens and authorized data within seven calendar days of revocation or a deletion request. You can manage content already uploaded to YouTube in YouTube Studio.
