N-of-1 Angina ("the App") is a personal symptom tracking tool for angina. Your privacy is important to us. This policy explains how the App handles your data.
The App does not collect, transmit, or share any personal data with third parties. All information you enter — including symptom diary entries, questionnaire results, medication lists, and generated reports — is stored on your device and synced via Apple's iCloud service to your other devices signed into the same Apple ID.
Your data is stored on your device using Core Data and synced securely to iCloud via Apple's CloudKit service. Simple settings such as your medications list are synced using iCloud Key-Value Storage. All iCloud data transfer and storage is handled by Apple and subject to Apple's iCloud Terms of Service. No data is sent to any other external servers or third parties.
The App does not use any analytics, advertising, or tracking frameworks. We do not collect usage statistics or device information.
The App does not integrate with any third-party services or SDKs that collect data.
The App includes a feature to generate PDF reports that you may choose to share with your healthcare provider. This sharing is initiated solely by you using the iOS share sheet, and the developers have no access to any shared reports.
You can delete individual diary entries by swiping to delete within the App. Deletions sync across all your devices via iCloud. Uninstalling the App removes local data; iCloud data may persist until removed from all synced devices or from iCloud storage settings.
The App is not directed at children under 13. We do not knowingly collect data from children.
We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated date.
