Privacy Policy

Last updated: March 26, 2026

Overview

CLUT 自己人 respects your privacy. We do not use any third-party services, analytics, or tracking. Our server only responds with what the upstream server provides — no data is collected, modified, or stored beyond what is described below.

Information We Collect

We collect the following information only when Live Activity is enabled, and solely for app functionality:

• 課表 (class schedule) — used to display your schedule in Live Activity
• IDFV (Identifier for Vendor) — used to identify your device for delivering Live Activity updates

This data is collected only while Live Activity is active and is used exclusively to provide the feature. No data is collected when Live Activity is disabled.

No Third-Party Services

We do not integrate any third-party SDKs, analytics tools, advertising frameworks, or tracking services.

No Tracking

We do not track your behavior, location, or usage patterns. We do not build user profiles or share any data with third parties.

Server Behavior

Our server acts as a transparent proxy — it only responds with what the upstream server provides. No additional data processing or storage occurs on our end.

Open Source

The client source code is publicly available at github.com/CLUT-OSS/chihlee-student-toolbox. The server source code is at github.com/HaeImCH/chihlee-school-api (private).
