WordSolid ("we", "us", or "our") operates the Learn Russian: 7000 Flashcards mobile application (the "Service"). This Service is provided as an ad-supported application and is intended for use as is.
This Privacy Policy explains how information is collected, used, and disclosed when you use our Service.
By using the Service, you agree to the collection and use of information in accordance with this Privacy Policy.
1. Information We Collect
We do not require users to create an account and we do not directly collect personal information such as names, email addresses, or phone numbers.
However, the Service uses third-party advertising services that may collect certain information automatically.

Google acts as an independent data controller for advertising data collected through AdMob. We do not have access to or control over the data collected by Google for advertising purposes.
2. Personalized and Non-Personalized Advertising
Depending on your location, you may be asked to provide consent for personalized advertising.
-
If you consent, ads may be personalized based on your interests.
-
If you decline or opt out, you will receive non-personalized ads.
You may change your advertising preferences at any time within the app’s settings (if available) or through your device settings.
You can also manage ad personalization through Google:
https://adssettings.google.com/
Please note that opting out of personalized ads does not remove advertising; it only affects how ads are selected.
3. Legal Basis for Processing (EEA and UK Users, Certain U.S. Users)
If you are located in the European Economic Area (EEA) or the United Kingdom, advertising data is processed:
-
Based on your consent (for personalized advertising), or
-
Based on legitimate interests (for non-personalized ads, fraud prevention, and security)
You have the right to:
-
Withdraw consent at any time
-
Request access to your personal data
-
Request correction or deletion of your personal data
-
Lodge a complaint with a supervisory authority
U.S. State Privacy Rights: Residents of certain U.S. states may have rights regarding access to or deletion of personal information.
Because advertising data is processed by Google as an independent data controller, requests related to such data should be directed to Google.
4. Data Retention
We do not directly store personal data collected through the Service.
Data collected by Google AdMob is retained in accordance with Google’s Privacy Policy.
Data Deletion
If you wish to request deletion of advertising or device-related data associated with your use of the Service, you may do so through Google’s privacy controls:

You may also reset your device’s Advertising ID through your Android device settings, which will dissociate prior advertising data from your device.
Data processed by Google AdMob is retained and deleted in accordance with Google’s Privacy Policy.
5. Sharing of Information
We do not sell or share personal information for monetary consideration.
Information may be processed by third-party service providers (such as Google AdMob) solely for the purposes described in this Privacy Policy.
6. Children’s Privacy & Age Verification
Our App is intended for a general audience (13+). To comply with global privacy regulations (such as GDPR and COPPA) and Google Play policies, we implement a neutral age screen upon first launch. The age screen does not encourage users to misrepresent their age and does not use pre-selected options.
-
Users Under 18: For users identified as under the age of 18, we automatically disable personalized advertising and request age-appropriate advertising content in accordance with Google’s advertising policies. We do not transmit your specific birth date to any servers.
-
Users 18 and Over: Users verified as 18+ may receive personalized advertisements and mature-rated ad content based on their consent preferences.
We use the Google User Messaging Platform (UMP) SDK to manage user consent and comply with regional privacy laws. You may be able to reset your consent preferences through the app (if available) or by reinstalling the application.
The Service is not intended for children under the age of 13.
We do not knowingly collect personal information from children under 13. If we become aware that personal information has been collected from a child under 13, we will take steps to address the issue in accordance with applicable laws.
If you are a parent or guardian and believe your child has provided personal information, please contact us.
7. Security
We value your trust and take reasonable measures to protect information associated with the Service. However, no method of transmission over the Internet or electronic storage is 100% secure, and we cannot guarantee absolute security.
8. Links to Other Sites
The Service may contain links to third-party websites. We are not responsible for the privacy practices or content of third-party services. We encourage you to review their privacy policies.
9. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. Changes will be posted within the app or on the page where this policy is hosted. Continued use of the Service after changes become effective constitutes acceptance of the updated policy.
