Cotidialogo Privacy Policy

Effective date: May 5, 2026

Cotidialogo is a Spanish vocabulary app published by Return Zero Studio, a product name operated by Cifra Systems LLC. This Privacy Policy explains how Cotidialogo handles information when you use the app.

Information we collect

Cotidialogo is designed to work without requiring you to create an account. We do not collect your name, email address, contacts, photos, precise location, or user-generated messages through the app.

The app may store app preferences and usage state locally on your device, such as language preference, speaker level, saved favorites, viewed words, onboarding status, notification preference, and Pro access state. This information is used to make the app function correctly and personalize your experience on your device.

Purchases

If you purchase Cotidialogo Pro, the transaction is processed by Google Play. We do not receive or store your full payment card number. Google may provide purchase status information needed to unlock Pro features and manage purchase restoration.

Notifications

If you enable notifications, Cotidialogo may use your device notification settings to send app reminders, such as a daily word reminder. You can disable notifications at any time in the app or in your device settings.

Audio and app content

Cotidialogo includes vocabulary content and audio files used to provide the app experience. Playing audio does not require you to provide personal information.

Third-party services

Cotidialogo uses Google Play services for app distribution and in-app purchase processing. Google may collect and process information according to its own policies when you use Google Play or make a purchase.

If future versions of Cotidialogo add analytics, crash reporting, advertising, accounts, cloud sync, or other third-party services, this Privacy Policy will be updated before or when those features are introduced.

How we use information

We use app information to provide core app functionality, remember your settings, manage access to Pro features, restore purchases, enable requested notifications, and improve app reliability.

Sharing of information

We do not sell your personal information. We do not share personal information with advertisers. Purchase-related information is handled through Google Play as needed to process purchases, verify entitlement status, and support purchase restoration.

Data retention and deletion

Most Cotidialogo app data is stored locally on your device. You can delete locally stored app data by deleting the app or clearing the app’s storage through your device settings. Purchase records are managed by Google Play according to Google’s policies and may remain associated with your Google account for purchase history, refund, tax, fraud prevention, and account-management purposes.

Children’s privacy

Cotidialogo is not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information to us, contact us so we can review and address the issue.

Security

We use reasonable measures to protect the app and the information it handles. No method of electronic storage or transmission is completely secure, but Cotidialogo is designed to minimize the personal information needed to use the app.

Changes to this policy

We may update this Privacy Policy from time to time. If we make material changes, we will update the effective date and revise this page.
