Privacy Policy

Last updated: November 12, 2026

crelve ("we", "us", or "our") operates the mobile application "Grateful Daily" (the "App"). This Privacy Policy explains how we collect, use, and protect information when you use the App. The App is available for iOS only.

1. Basic policy

• The App has no account registration. It does not ask you to enter your name or email address. In the background, the App signs you in with Firebase Authentication anonymously, using an anonymous ID that is not linked to your name, email address, or Apple ID. This ID is also used to link your purchases in RevenueCat.
• The gratitude entries you record are stored on your device. We do not upload them to our servers, except for the text sent to the AI service when you use an AI feature, as described in Section 3.1.
• AI features are used only after you explicitly agree to send data to the AI service.

2. Information we collect

2.1 Information you provide

• Gratitude entries (text you record in the App; stored on your device)
• Notification preferences (such as reminder time)
• Language and theme settings

2.2 Information collected automatically

• Anonymous ID issued by Firebase Authentication and Firebase installation ID
• Device information (device type, OS version, app version, unique identifiers)
• Usage data (screen views, feature usage, session duration)
• Crash logs and error reports
• Push notification token (Firebase Cloud Messaging)
• Purchase and subscription status (via RevenueCat and the App Store)
• Ad interaction data (ad impressions, clicks) and, if you allow tracking, the advertising identifier (IDFA)
• Your IP address, which is received by the services listed in Section 3 when the App communicates with them

3.1 AI features and data sent to a third-party AI service

What is sent. The App has two AI features: the weekly review, and the AI encouragement shown after you record gratitude. When you use one of them, the gratitude text you recorded (the entries of the week for the weekly review, or the entries you just recorded for the encouragement), together with an instruction prompt and your app language code, is sent from your device to the Gemini AI service operated by Google LLC, through Firebase AI Logic. No images are sent. Your name, email address, contacts, location and device identifiers are not included in these requests.

How it is collected and used. The data is sent only at the moment you request an AI feature, and it is used solely to generate and return the response you asked for. We do not use it for advertising, profiling or any other purpose. The weekly review result is cached on your device.

Your permission. The App asks for your explicit permission (Agree or Decline) before any data is sent to this service. AI features stay disabled unless you agree, and the rest of the App works normally if you decline. If you have not yet decided when you use an AI feature, the App asks again at that moment. You can change your choice at any time from the App's settings screen.

Third-party protection. Google processes this data as our service provider under the Firebase and Google Cloud terms, which require it to protect the data to a standard equivalent to the one described in this Privacy Policy.

4. How we use your information

We use the collected information for the following purposes:

• To provide and operate the App services, including AI features and notifications
• To manage subscriptions and purchases
• To display ads in the free version
• To provide customer support
• To improve the App and develop new features
• To analyze usage patterns and diagnose crashes
• To prevent fraudulent use

5. Advertising

The free version of the App displays ads (banner, interstitial, rewarded, app-open and native ads) through Google AdMob and its mediation partners (AppLovin and Unity Ads). These services may use advertising identifiers to deliver and measure ads. In regions where consent is required, the App asks for your consent through Google's User Messaging Platform. Premium subscribers do not see ads. To limit ad personalization, you can turn off tracking for the App in iOS Settings, or enable "Limit Ad Tracking" on your device.

6. Information sharing

We do not share your personal information with third parties except in the following cases:

• With your consent
• When required by law
• When necessary to protect life, body, or property
• With the service providers listed in "Third-party services" above

7. Data retention

Gratitude entries and settings are stored on your device and remain until you delete them or delete the App. Because the App has no account, we cannot identify you from your entries. Data held by the third-party services listed above (such as analytics, crash reports and the anonymous ID) is retained under their own policies. If you want us to delete data associated with your anonymous ID, contact us using the information below.

8. Data security

We implement industry-standard security measures to protect collected information. However, no method of transmission over the Internet or electronic storage is 100% secure.

9. Your rights

You have the following rights:

• Access: Request access to the personal information we hold about you
• Correction: Request correction of inaccurate personal information
• Deletion: Request deletion of your personal information
• Data portability: Request a copy of your personal information

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

10. Children's privacy

This App is not intended for children under 13 years of age. We do not knowingly collect personal information from children under 13. If we learn that we have collected personal information from a child under 13, we will delete it promptly.

11. App Tracking Transparency

On devices running iOS 14.5 or later, the App asks for permission before tracking your activity across other companies' apps and websites. If you do not allow tracking, ads are still shown but are less relevant to you, and you can still use all basic features of the App. You can change your choice at any time in iOS Settings.

12. Changes to this policy

We may update this Privacy Policy as needed. We will notify you of significant changes through the App or other means. The updated Privacy Policy will take effect when posted on this page.
