China Ready Travel is designed so most core trip data stays on your device. This page explains how to avoid optional uploads, revoke permissions, and remove local information.
If you do not want information sent to the feedback backend, simply do not use the in-app feedback form. Feedback submission is optional.
The current release is centered on local storage. Most trip data stays on the device rather than being exposed as an active in-app cloud sync feature for users.
Most trip data in China Ready Travel is stored locally on your device. Deleting the app generally removes local app data from that device, subject to the way iOS manages device backups.
You can change permissions at any time in iOS Settings. This affects only the feature tied to that permission.
Referral data tied to affiliate links is shared only when you choose to open a partner travel service link. If you do not want that, do not tap the partner link from inside the app.
