Crest WeDo Privacy Policy

Effective September 24, 2026. This policy applies to the Crest WeDo Android app, version 0.1.5.

Crest WeDo is an offline robotics programming app for users of all ages, including children. It does not require an account and does not include advertising, analytics, or an application server. The app does not automatically send projects, sensor readings, microphone audio, or activity logs to Crest.

Projects and files

Projects and project names are saved in the app's storage on your device. Save file lets you export a JSON copy to a location you choose. Load file reads only the JSON file you select. Uninstalling the app can erase projects stored in the app, so save a copy first. Files you export are managed by the storage location and sharing choices you select.

Bluetooth hub

When you tap Connect hub, Android's companion device chooser finds a nearby WeDo 2.0 Smart Hub. On Android 12 and later, the app requests Bluetooth connection permission. It exchanges motor commands, sensor readings, hub name, and battery status with the selected hub. Crest WeDo does not request location permission, determine your position, or upload this information.

Microphone

Microphone sensing is optional. If you enable it, Android requests microphone access. Sound level is processed on your device while the feature is on; the app does not record or upload audio. You can turn it off in Hub & teacher tools or close the app.

Connection activity log

The optional connection activity log remains in the app's memory until it closes. Save test log writes the log, time, and device browser identifier to a text file only if you select a location. There is no automatic cloud sync.

External services

The app's LEGO attribution link opens an external document in a browser only if you select it. Google Play installation and updates, and any services you use to store or share exported files, are separate from Crest WeDo.
