Privacy Policy — PenDose
Last updated: 2026-05-06
1. Summary
PenDose is designed to keep dose logs, side effect records, and health data on your device. We use Apple and RevenueCat to process in-app subscriptions and entitlement status. We do not sell your personal data.
2. Information We Process
Depending on how you use PenDose, the app may store locally your dose schedule and injection logs, side effect entries, injection site history, weight entries, and app preferences. If you enable HealthKit integration, the app reads data from Apple Health with your explicit permission using Apple's HealthKit framework. PenDose does not write health data to HealthKit without separate explicit permission.
3. Subscription and billing information
If you purchase or restore a subscription, billing and receipt processing is handled by Apple and RevenueCat. Data processed can include product identifiers, purchase and renewal events, entitlement status, and app user identifiers needed to validate purchases.
4. Diagnostics and security metadata
We and our service providers may process limited technical data required for reliability, abuse prevention, and troubleshooting.
5. Third-Party Services
PenDose uses Apple App Store / StoreKit for payments and subscriptions, Apple HealthKit for optional health data integration, and RevenueCat for subscription infrastructure and entitlement management. See https://www.apple.com/legal/privacy/ and https://www.revenuecat.com/privacy.
6. How We Use Information
We use data to provide app functionality, verify subscription entitlement and restore purchases, improve reliability and security, and comply with legal obligations.
7. Data Sharing
We share data only as needed with processors and platforms that enable the app to function (Apple, RevenueCat), legal compliance, and security operations. We do not sell personal information.
8. Data Retention
On-device health and dose records remain on your device unless you delete them. Subscription records are retained by Apple and RevenueCat under their own retention policies.
9. Your Choices and Rights
You can manage or cancel subscriptions in Apple account settings, use Restore Purchases to re-sync entitlements, revoke HealthKit access at any time in iPhone settings, and contact us for privacy requests.
10. Medical Disclaimer
PenDose is a personal tracking and organizational tool. It is not a medical device and does not provide medical advice. Always follow the guidance of your prescribing healthcare provider for all dosing decisions.
11. Children
PenDose is not directed to children under 13. We do not knowingly collect personal data from children in violation of applicable law.
12. Changes to This Policy
We may update this Privacy Policy from time to time. The Last updated date will be revised when changes are posted.
