Privacy Policy (English)
Last updated: 3 May 2026
Kwan Chun Kit Construction Ltd. ("we", "us") develops and operates the "Construction Management"
mobile application ("the App"). This Privacy Policy explains how we collect, use, store, and protect
user data. By using the App, you agree to this policy.

2. Camera / Photo Library Permissions
The App may request camera or photo library access only when you actively choose to attach photos
to an issue report. We only upload photos you explicitly select. You can revoke these permissions
at any time in iOS Settings → Notifications / Camera / Photos.
3. Push Notifications
We send push notifications via OneSignal for the following events:
- New issue reported (to handler-level personnel)
- Issue escalated (to next-level handler)
- Issue resolved (to reporter)

- You were assigned as PM or task owner
You can disable push notifications at any time in iOS Settings → Notifications → "CK Construction".
We never use push notifications for marketing or advertising.
4. Storage and Third-Party Services
App data is stored on the following third-party infrastructure:
-
Supabase (database + file storage)
— servers in US / EU. All data transmitted over HTTPS; passwords stored as bcrypt hashes.
https://supabase.com/privacy
-
OneSignal (push notification routing)
— receives only user identifiers for delivery targeting; does not receive personal data,
photos, or project content.
https://onesignal.com/privacy_policy
-
Apple (APNs)
— only delivers notification tokens; does not store content.
5. Data Retention and Deletion
- Account data: retained until account deletion.
- Project data (progress, issues, photos): retained for the duration of the project as construction records.
- You may contact us at any time to request deletion of your account and associated data.
- System logs: automatically deleted after 90 days.
6. Data Sharing
We do not sell or share your data with advertisers or marketing companies.
We share data only when:

- Required by law or government authority.
7. Security
