Privacy Policy

This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application (the “App”).

By using the App, you agree to the collection and use of information in accordance with this Privacy Policy.


1. Information We Collect

1.1 Information You Provide Voluntarily

We only collect personal information when you choose to provide it, such as:

  • Contact information (e.g., email address) when you contact us for support or feedback

We do not require account registration to use the core features of the App unless explicitly stated in the App.

1.2 Purchase Information

Any payments are processed directly by the applicable app marketplace provider (such as the Apple App Store or Google Play Store). We do not collect or store your payment method details, such as credit card numbers or billing information.

We use RevenueCat, a third‑party subscription management service, to manage and validate any subscription or payment status. Through RevenueCat, we may receive limited information related to your purchase, including:

  • Subscription status (active, expired, cancelled)
  • Product identifiers
  • Transaction or receipt identifiers

This information is used solely to provide subscription functionality and manage entitlements.

1.3 Automatically Collected Information

Crash and Diagnostics Data

We use Firebase Crashlytics to collect crash reports and diagnostic data to improve app stability and performance.

This data may include:

  • App state at the time of a crash
  • Device type, operating system version, and manufacturer
  • Anonymous installation identifiers
  • Crash logs and stack traces

Crash reports are not used to identify individual users.

We do not use advertising identifiers and do not collect data for ad targeting purposes.

Usage Analytics (Theme and Feature Usage)

We use Firebase Analytics to collect limited, non-personal usage data about how the App is used. This may include:

  • Which themes or visual styles are selected or used
  • General feature interactions related to themes
  • Aggregated usage patterns and event counts

This data is collected in an aggregated and anonymized manner and does not identify individual users.

We use this information solely to understand the popularity of the themes and services we provide, improve service quality, and guide future feature development. Firebase Analytics data is not used for advertising, profiling, or cross-app tracking.


2. How We Use Your Information

We use the collected information only for the following purposes:

  • To provide and maintain the App
  • To process and manage subscriptions
  • To respond to user inquiries and support requests
  • To detect, prevent, and fix technical issues
  • To improve app stability, performance, and reliability
  • To analyze aggregated usage trends (such as theme popularity) and improve service quality

We do not sell your personal data.


3. Sharing of Information

We only share your information in the following limited circumstances:

3.1 Service Providers

We share information with trusted third‑party service providers that help us operate the App, such as:

  • Subscription and purchase management
  • Crash reporting and diagnostics
  • Usage analytics (including Firebase Analytics)

These providers process data only on our behalf and only for the purposes described in this Privacy Policy.

We may disclose information if required to do so by law or if we reasonably believe such action is necessary to:

  • Comply with a legal obligation
  • Protect the rights or safety of users or others
  • Prevent fraud or abuse


4. Data Retention

We retain personal information only for as long as necessary to fulfill the purposes described in this Privacy Policy, unless a longer retention period is required or permitted by law.

Crash and diagnostic data is retained for a limited period and used solely for internal analysis and app improvement.


5. International Data Transfers

Your information may be processed and stored on servers located outside your country of residence. We take reasonable steps to ensure that your data is handled securely and in accordance with this Privacy Policy, regardless of where it is processed.


6. Your Rights and Choices

Depending on your location, you may have certain rights regarding your personal information, including:

  • The right to access the personal data we hold about you
  • The right to request correction or deletion of your data
  • The right to withdraw consent where processing is based on consent

You can exercise these rights by contacting us using the details below. We will respond within a reasonable timeframe.


7. Security

We use commercially reasonable technical and organizational measures to protect your information. However, no method of electronic storage or transmission is completely secure, and we cannot guarantee absolute security.


8. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be posted within the App or on the app store listing, and the “Last updated” date will be revised accordingly.

Your continued use of the App after changes become effective constitutes acceptance of the updated Privacy Policy.
