These apps do not collect, store, or share any personal data.
Each app runs entirely on your Apple Watch. No data is transmitted to external servers. Any settings you choose are stored only on your device and are removed when you delete the app.
No user data is collected, tracked, or shared with any third parties. These apps contain no analytics, no advertising, and no third-party SDKs.
One Arcana can show a daily reminder if you turn it on. Notifications are scheduled locally on your Apple Watch. Nothing is sent to or through any server. You can turn them off at any time in the app.
These apps do not collect any information from anyone, including children under 13.
