Privacy Policy

Last updated: February 2026

Your data stays with you

Cadence is designed with privacy at its core. Your medication schedules, dose history and streaks are stored locally on your device and synced privately via iCloud to keep your iPhone and Apple Watch in sync. This data is stored in your personal iCloud account and governed by Apple's Privacy Policy. We do not operate servers that store your health data. If you choose to connect Apple Health, data is exchanged directly between Cadence and the Health app on your device. It is never sent to us.

What we collect

We collect minimal, non-identifiable data to improve the app experience:

• Anonymous usage analytics (e.g. which features are used most frequently)
• Crash reports and performance data
• Device type and operating system version

This data cannot be linked back to you or your health information.

What we never collect

• Medication names, dosages or schedules
• Dose history or adherence data
• Health conditions or personal medical information
• Your name, email or contact details (unless you contact us directly)
• Any data from Apple Health

Apple Health integration

Cadence offers an optional integration with Apple Health. This feature is entirely opt-in and can be enabled or disabled at any time in Settings.

What we read from Apple Health

• Heart rate
• Blood pressure
• Weight
• Blood glucose
• Step count

This data is displayed in the Insights tab alongside your medication adherence to help you spot trends. It is read on-device and never transmitted to our servers.

What we write to Apple Health

• Symptom data from journal entries (e.g. headache, nausea, fatigue)
• Mood data from journal entries

This data is written directly to the Health app on your device. We do not access, sell or share any Apple Health data with third parties, advertising networks or data brokers. Apple Health data is never used for advertising or marketing purposes.

Drug interaction data

Interaction checks are performed using a database bundled within the app. Your medication list is never sent to an external server for this purpose.

Third-party services

We may use third-party services for anonymous analytics and crash reporting. These services receive only non-identifiable technical data and are bound by their own privacy policies.

Data deletion

You can delete all your data at any time from within the app (Settings > Privacy > Delete All Data). This removes all medications, dose history and settings from your device. Deleting the app also removes all local data. Data synced to iCloud can be managed through your iCloud settings. There is nothing for us to delete on our end because we do not store your data on our servers.

Your rights

California residents (CCPA): You have the right to know what personal information is collected, request its deletion and opt out of the sale of personal information. Cadence does not sell your personal information.

European Economic Area residents (GDPR): You have the right to access, correct, delete or port your personal data, and to object to or restrict its processing. Since Cadence stores data on your device and iCloud, you exercise these rights directly through your device and iCloud settings.

Because Cadence does not maintain user accounts or store your health data on our servers, most data rights are exercised directly on your device.

Changes to this policy

We may update this policy from time to time. Any changes will be reflected on this page with an updated date. Continued use of Cadence after changes constitutes acceptance of the updated policy.
