CardioShift does not require an account and does not transmit your activity to any server. Quiz score, best streak, completed questions, bookmarks, and text-size preference are stored only in your device's local app storage, and never leave your device.
This app contains no analytics SDKs, advertising identifiers, or third-party trackers.
Some cards link out to published trials and guidelines (for example, on journal or DOI websites). Following those links opens your device's browser and is subject to that third-party site's own privacy policy — CardioShift has no control over those sites.
Uninstalling the app, or clearing its storage in your device settings, permanently deletes all locally stored quiz progress and bookmarks.
Questions about this policy can be sent to cardioshift@outlook.com.
