Privacy Policy

Dear Diary is designed with privacy as a core principle. We aim to collect the minimum amount of information necessary to provide app functionality, improve reliability, and protect our services from abuse.

Your journal entries, mood logs, tags, notes, and other journal content are stored locally on your device and are not transmitted to or stored on our servers.

To provide app functionality, we may collect and process limited information, including:

Technical Information

• A pseudonymous device identifier generated as a one-way hash
• Push notification tokens used to deliver reminders and notifications
• Timezone information used to schedule notifications correctly
• Notification preferences and related application settings

Security Information

To protect our services against abuse, excessive requests, and automated attacks, we may temporarily process a cryptographic hash derived from your IP address.

• Raw IP addresses are not intentionally stored for rate-limiting purposes.
• Hashed IP information is retained only for a limited period necessary to enforce rate limits and maintain service security.

Analytics Information

We use analytics tools to understand how the application is used and to improve performance, reliability, and user experience.

Analytics information may include:

• App launches
• Screen views
• Feature usage
• Device characteristics
• Operating system version
• App version
• Performance metrics
• Crash and diagnostic information

We do not collect, transmit, analyze, or store the contents of your journal entries through our analytics systems.

Subscription Information

If you purchase a subscription, subscription status and transaction-related information may be processed by our subscription management provider and the applicable app store.

We do not store your payment card details.

We use collected information to:

• Deliver notifications and reminders
• Maintain notification preferences
• Verify and manage subscriptions
• Improve app performance and reliability
• Understand feature usage
• Diagnose technical issues
• Protect services against abuse, fraud, and excessive automated requests
• Comply with legal obligations where applicable

We do not sell, rent, or trade personal information to third parties.

Journal entries, notes, mood logs, tags, and other journal content are stored locally on your device.

We do not upload, synchronize, analyze, read, or store your journal content on our servers.

If cloud synchronization or backup features are introduced in the future, they will be clearly disclosed and will require your explicit action to enable.

Dear Diary provides optional PIN and biometric protection to help secure access to your journal.

PIN credentials and related security settings are stored locally on your device using platform-provided secure storage mechanisms where available.

Biometric authentication is performed by your device's operating system. We do not receive, store, or process biometric information.

We use trusted third-party providers to support application functionality.

Firebase

We use Firebase services provided by Google, including:

• Firebase Analytics
• Firebase Cloud Messaging (FCM)

These services help us understand app usage, improve reliability, and deliver notifications.

RevenueCat

We use RevenueCat to manage subscriptions and validate purchase status.

Platform Providers

Payments and subscription transactions are processed by:

• Google Play Store
• Apple App Store

These providers process information according to their own privacy policies and terms.

We do not use third-party advertising networks and do not sell user data for targeted advertising.

Journal content remains stored locally on your device until you delete it or uninstall the application.

Server-side technical information is retained only for as long as reasonably necessary to provide app functionality, subscription services, analytics, security protections, and operational support.

Hashed IP data used for rate limiting is retained only for a short period necessary to enforce service protections.

You may request deletion of server-side information associated with your device by contacting us using the contact information below.

Because journal entries are stored locally on your device, you may delete them directly within the application or by removing the application from your device.

Dear Diary is intended for users aged 13 years and older.

We do not knowingly collect personal information from children under the age of 13. If we become aware that information from a child under 13 has been collected, we will take reasonable steps to delete it.

Depending on your location, you may have rights under applicable privacy laws, including rights relating to access, correction, deletion, or restriction of certain personal information.

To exercise these rights, please contact us using the details below.

We may update this Privacy Policy from time to time.

When significant changes are made, we may notify users through the application and update the "Last Updated" date above.

Continued use of Dear Diary after changes become effective constitutes acceptance of the updated Privacy Policy.
