Vocabuo s.r.o. ("we", "us", or "our") operates the Vocabuo application (the "Service") as a commercial product. This Privacy Policy explains how we collect, use, and disclose information about you when you use our Service. By using the Service, you agree to the collection and use of information in accordance with this policy.
1. Information We Collect
We collect the following categories of personal information:
Account information: Email address, collected when you register via email/password or sign in via Google or Apple.
Usage and analytics data: Information about how you interact with the app, including features used, session duration, and in-app events, collected through Google Analytics and PostHog.
Purchase and subscription data: Records of subscriptions or in-app purchases processed through the Apple App Store or Google Play, and managed via Adapty. We do not process payment card data directly; this is handled by the respective platform.
Log data: In the event of an error, we may collect technical information such as your device's IP address, device model, operating system version, app configuration, and timestamps.
2. How We Use Your Information
We use the information we collect to:
Create and manage your account
Provide, operate, and improve the Service
Process and manage your subscription or in-app purchase
Analyze usage patterns to improve app features and performance
Diagnose and fix technical issues
Comply with legal obligations
3. Third-Party Service Providers
We use the following third-party services that may process your personal data on our behalf. Each is governed by its own privacy policy:
Google Cloud Platform: Backend infrastructure and data storage. Data may be stored on Google's servers within the EU or other regions.
Google Analytics: Usage analytics and app performance monitoring.
Google Sign-In / Apple Sign-In: Third-party authentication providers.
Google Play Services: App distribution, in-app purchases, and platform-level services on Android.
Apple App Store: App distribution and in-app purchases on iOS.
Adapty: Subscription and in-app purchase management, including entitlement tracking, paywall analytics, and revenue reporting. Adapty may process your purchase history and device identifiers.

These providers are authorized to use your information only to perform services on our behalf and are obligated not to disclose or use it for any other purpose.
4. Data Retention
We retain your personal data for as long as your account remains active. When you delete your account — which you can do at any time directly within the app — your personal data is deleted from our systems. Certain residual data may be retained for a short period as required for backup, legal, or fraud-prevention purposes.
5. Your Rights
EU/EEA Users (GDPR)
If you are located in the EU or EEA, you have the following rights under the General Data Protection Regulation (GDPR):
Right to access, correct, or delete your personal data
Right to restrict or object to processing
Right to data portability
Right to lodge a complaint with your local supervisory authority
Our legal basis for processing your data is the performance of a contract (providing the Service), our legitimate interests in improving the Service, and compliance with legal obligations.
US Users (California and other state laws)
If you are a California resident, you have rights under the California Consumer Privacy Act (CCPA) / CPRA, including the right to know what personal information we collect, the right to delete your personal information, and the right to opt out of the sale of your personal information. We do not sell personal information.
To exercise any of these rights, you may delete your account directly in the app or contact us at the address below.
6. Cookies and Tracking
The Vocabuo app does not use browser cookies. However, third-party analytics services integrated in the app (such as Google Analytics and PostHog) may use device identifiers and similar technologies to collect usage data. You may be able to limit this through your device's privacy settings (e.g. opting out of ad tracking on iOS or Android).
7. Security
We take the security of your personal data seriously and implement commercially reasonable technical and organizational measures to protect it, including secure infrastructure on Google Cloud Platform. However, no method of transmission over the internet or electronic storage is 100% secure, and we cannot guarantee absolute security.
8. Children's Privacy
Our Service is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that a child under 13 has provided us with personal information, we will take steps to delete such data promptly. If you are a parent or guardian and believe your child has provided us with personal information, please contact us.
9. Links to Other Sites
Our Service may contain links to third-party websites or services. We have no control over and assume no responsibility for the content, privacy policies, or practices of any third-party sites. We encourage you to review the privacy policy of any site you visit.
10. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. We will notify you of any significant changes by posting the updated policy on this page and updating the effective date.
