Arc App collects location and motion data from your phone and stores it securely on your phone.
This data is processed locally on your phone, and is presented in the app to give you insights into your daily activities.
If you opt in to Arc's iCloud backups, the data is backed up to your secure private iCloud account, which is only accessible by you.
Your confirmations and corrections of transport activities are anonymised and contributed to improve the accuracy of Arc's activity type detection. You can opt out of these anonymous contributions by disabling Correction Sharing.
Arc App is designed with the intent that access to your data is only possible by you personally.
None of your data is shared with third parties, for any purpose.
