ReefDiary Privacy Policy

Last updated: June 2026

Overview

ReefDiary is designed with your privacy in mind. We do not collect, store, or transmit any personal data.

Data Storage

All data you enter into ReefDiary (tank information, water test results, dosing calculations) is stored locally on your device using Apple's SwiftData framework. This data never leaves your device.

Data Collection

ReefDiary does not collect:

• Personal information
• Location data
• Usage analytics
• Device identifiers
• Crash reports

Third-Party Services

ReefDiary does not integrate with any third-party analytics, advertising, or tracking services. The only external service used is Apple's StoreKit for in-app subscription management.

Subscriptions

Subscription purchases are processed entirely through Apple's App Store. We do not have access to your payment information.

Data Deletion

You can delete all your data at any time by deleting the app from your device. Since no data is stored externally, deletion is complete and permanent.

Children's Privacy

ReefDiary does not knowingly collect information from children under 13.

Changes

We may update this policy from time to time. Changes will be reflected on this page with an updated date.
