YuBook プライバシーポリシー

YuBook は X 投稿の下書きをブラウザ内で分析し、代理投稿は行いません。広告 SDK・第三者トラッキングも使用しません。施行日 2026-08-16。

1. Data we collect

Account data (email or connected X account identifier), subscription and billing status, and service usage logs. Payments are processed by Paddle as merchant of record.

2. How drafts are handled

Draft analysis runs entirely in your browser. What you type is not sent anywhere and is not stored.

3. We never publish for you

YuBook does not publish on your behalf. A connected X account is used only to read performance metrics.

4. Connecting X

When connected, we read public metrics (reach, profile visits, follow conversion, conversation rate) to compare prediction with actual results. You can disconnect at any time.

5. Public signals and forecasts

Public X weights and your measured outcomes are stored and processed separately, and forecasts are shown as ranges. This is not an official X score.

6. Retention

Account and performance data are kept up to 12 months after your subscription ends, then deleted. Immediate deletion on request.

7. Third parties

We do not sell or share your data, except with processors required to run the service (Paddle for payments, infrastructure and email providers).

8. No ad tracking

No advertising SDKs and no third-party behavior trackers are bundled.

9. Your rights

Send access, correction, deletion or stop-processing requests to contact@legitstudio.cc.
