CameraScript doesn’t collect any user data.
CameraScript doesn’t connect to the internet, so no information leaves your device via the app. You can verify this by checking the app permissions.
CameraScript writes captured images to your device's storage, which can be read by any app with the appropriate permissions. This is true of any reasonable camera app so that these images can be viewed in the gallery, shared on social media, etc. None of these operations are provided by the CameraScript app itself, due to the previous privacy points.
