Privacy Policy

Effective November 13, 2026. This policy describes the data practices of SYJ CTR Trial, operated by Sakura Sensei for Speak Your Japanese.

Data accessed and why

The tool uses the YouTube Reporting API under authorization from the channel owner. It processes channel and video IDs, reporting dates, thumbnail impressions, thumbnail impression click-through rate, and report IDs and timestamps. The tool uses these data to maintain a daily record and to review channel performance. It does not request viewer identities, messages, revenue data, or the ability to edit YouTube videos.

Storage and access

The tool runs on Google Apps Script and writes report data to a private Google Sheet. Access is limited to the operator’s authorized account. Metrics are retained only as needed for the authorized purpose. The scheduled API access checks authorization. The operator will honor deletion requests and remove data following revocation within applicable YouTube API policy deadlines. The public website is hosted on Cloudflare Pages and does not display reports or collect form submissions. The hosting service may process standard request information to deliver and secure the pages.

Sharing and controls

The reporting tool does not sell Google user data or share the report data with advertisers. Google provides the reporting, authorization and storage services. This tool’s use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. See also the Google Privacy Policy.

You can revoke access from the Google Account security permissions page. To ask a question, raise a concern, or request a copy or deletion of data stored by this tool, email sakurasenseijapanese@gmail.com. The operator will fulfill deletion requests for the tool’s stored data as soon as possible and within seven calendar days. Deletion from this tool does not change data held by YouTube.
