Last updated: September 8, 2026
This Privacy Policy explains how data is handled in the WWL: Word Duel mobile application (“WWL” or the “App”).
1. Developer and Contact Information
Developer: ucystudio (FURKAN GUC)
Contact email: ucystudio@gmail.com
Application: WWL: Kelime Düellosu
If you have any questions about this Privacy Policy, the App, or your privacy rights, you may contact us using the email address above.
2. General Approach to Data Processing
WWL primarily stores game progress locally on the user’s device. In the current version, no cloud account or game server operated by ucystudio is used to store game progress.
The App does not:
- Request the user’s full name, telephone number, or postal address.
- Access the device’s camera, microphone, photos, or contacts.
- Request precise location permission.
- Provide user-to-user messaging or chat features.
- Create public user profiles.
- Sell user data.
- Send game progress to servers operated by ucystudio for advertising or marketing purposes.
However, the App uses Google AdMob to display advertisements. As a result, certain device, advertising, interaction, and technical data may be processed by the Google Mobile Ads SDK. Further information is provided in the “Advertising and Third-Party Data Processing” section of this Privacy Policy.
3. Game Information Stored on the Device
To operate the game, preserve user preferences, and maintain progress, the following information may be stored locally on the user’s device:
- The player name or nickname selected by the user
- Selected application language
- Onboarding and tutorial completion status
- Selected game mode and bot difficulty
- Unlocked and completed World Journey levels
- Level rewards and previously claimed rewards
- Match date, opponent name, result, game mode, and scores
- Game statistics, including matches played, wins, highest score, total words created, and total letters used
- League, season, fixture, ranking, points, and score-difference records
- Previous season and match records
- Quantities of in-game aids such as Magnet, Time Extension, and Professor
- Daily reward progress and the last reward collection date
- Championship and milestone reward status
- Content variety and adaptive difficulty information
- Music, sound effect, haptic feedback, and reduced-animation preferences
- Active gameplay time used to calculate interstitial advertisement frequency
- The local entitlement status of the “Remove Ads” purchase
- Legacy in-game economy records and, where applicable, previously processed purchase transaction identifiers
This information may be stored using on-device technologies such as Hive, SharedPreferences, or SQLite.
Users are encouraged to enter a nickname rather than their real name in the player name field. The selected player name cannot be viewed by ucystudio and, in the current version, is not transmitted to a developer-operated server with the user’s game progress.
Deleting the App, clearing its application data, or resetting the device may permanently delete locally stored game information. ucystudio cannot view or remotely restore this local game information.
Non-consumable purchases linked to the user’s store account, such as “Remove Ads,” may be restored through the Apple App Store or Google Play.
4. Words Used in the Game
Words created by the player are checked locally on the device using the Turkish or English word database included with the App.
Words entered by the player:
- Are not transmitted to servers operated by ucystudio.
- Are not used for advertising.
- Are not processed to create a user profile.
- Are not stored by ucystudio as a permanent word history.
The App may store general gameplay statistics, such as the total number of words and letters used, locally on the user’s device.
5. Advertising and Third-Party Data Processing
WWL uses Google AdMob and the Google Mobile Ads SDK to display advertisements.
The App may include the following advertisement formats:
- Interstitial advertisements displayed at certain intervals during gameplay
- Rewarded advertisements that users may voluntarily watch to receive in-game rewards
According to Google, the Google Mobile Ads SDK may process information including:
- IP address and approximate location inferred from the IP address
- Advertising identifiers or other app- or developer-bounded device identifiers
- Advertisements viewed and interactions with advertisements
- Video views and application interaction information
- Application performance information, such as launch time
- Crash logs and diagnostic information
This information may be used to deliver advertisements, measure advertising performance, prevent fraud, maintain service security, and improve advertising services.
For more information about the Google Mobile Ads SDK’s data practices, please review:
Google Mobile Ads SDK – App Store Data Disclosure
The App may use Google’s User Messaging Platform to manage advertising privacy and consent choices in applicable regions. Where required, a privacy or consent message may be displayed before advertisements are requested.
Whether personalized, non-personalized, or limited advertisements are displayed may depend on the user’s region, device settings, applicable age-related requirements, and consent preferences.
The current iOS version of WWL does not directly request App Tracking Transparency permission. However, Google may still process technical information or identifiers other than the advertising identifier to provide advertising services.
ucystudio does not directly control Google’s independent data-processing activities and does not sell user data to Google.
6. Google Play Games and Firebase Authentication
This section applies only to the Android version of the App.
The Android version may use Google Play Games Services to check whether the user is signed in to a Google Play Games account and to verify the user’s platform player identity.
During this process, the following information may be processed by Google Play Games and Firebase Authentication:
- Google Play Games player identifier
- Game profile information associated with the user’s Google account
- Authentication information
- Server authorization code
- Firebase Authentication user identifier
WWL does not receive, view, or store the user’s Google account password. Authentication is performed by Google.
In the current version, game progress is stored locally on the device. Firebase Analytics is not used, and normal gameplay progress is not transmitted to Firebase Firestore.
For more information about data processing by Google and Firebase, please review:
Firebase Privacy and Security Information
7. In-App Purchases
WWL may offer a one-time, non-consumable in-app purchase called “Remove Ads,” which permanently removes interstitial advertisements.
All payment transactions are processed by the Apple App Store or Google Play, depending on the user’s platform.
ucystudio does not:
- Receive credit or debit card information.
- View the user’s payment information.
- Store payment information on its own servers.
- Use payment information for advertising or marketing purposes.
To verify a purchase, grant the entitlement, prevent duplicate fulfillment, and restore purchases where appropriate, the App may process the product identifier, transaction status, transaction identifier, and verification information provided by the applicable application store.
The “Remove Ads” purchase removes interstitial advertisements. Rewarded advertisements that users voluntarily watch to receive in-game rewards may remain available.
Purchase and payment records are subject to the retention periods, terms, and privacy policies of the applicable application store.
8. Analytics, Diagnostics, and Crash Reporting
The current version of WWL does not use Firebase Analytics, Google Analytics, Meta SDK, or an independent user analytics system operated by ucystudio.
However, the Google Mobile Ads SDK may process advertising interactions, performance information, device information, crash logs, and other technical data to provide advertising services, measure performance, and diagnose problems.
Normal gameplay statistics and game progress are not automatically transmitted to ucystudio.
9. Sharing of Information
ucystudio does not sell personal data or provide it to data brokers for marketing purposes.
During the operation of the App, information may be processed by the following independent service providers:
- Google AdMob for delivering advertisements
- Google Play Games and Firebase Authentication for Android platform identity
- Apple App Store or Google Play for in-app purchases
- Email service providers when a user voluntarily sends a support email
The data-processing activities of these providers are governed by their own privacy policies and terms of service.
10. Data Retention and Deletion
Game information stored on the device may remain there until the user deletes the App, clears the App’s data, or uses an available reset option.
Because local game information is not stored on ucystudio servers, ucystudio cannot remotely delete, modify, retrieve, or provide this information to the user.
In-app purchase records may be retained by Apple or Google according to their legal and operational retention requirements. Deleting the App does not automatically delete purchase history associated with the user’s application store account.
Options for deleting or managing information processed by advertising services may be available through Google’s privacy and account-management tools.
11. Support Communications
If a user voluntarily sends an email to ucystudio@gmail.com, the email address and any information included in the message may be used only to:
- Respond to the support request
- Investigate a technical problem
- Perform an action requested by the user
- Comply with legal obligations
Support communications are not used for advertising, added to marketing lists, or sold to data brokers.
Users are advised not to include unnecessary personal, financial, or sensitive information in support messages.
12. Children’s Privacy
WWL is a general-audience word game and is not specifically designed for children.
The App does not provide user-to-user chat, public profiles, or social media features that allow users to publish content.
If you believe that personal information belonging to a child has been submitted through the support email, please contact ucystudio@gmail.com so that the information can be reviewed and deleted where appropriate.
13. Data Security
Because local game progress is stored on the user’s device, its security largely depends on the operating system and security settings of that device.
Users are encouraged to:
- Keep their devices updated.
- Use a screen lock.
- Protect their Apple or Google accounts.
- Enable two-factor authentication where available.
Advertising, store, and authentication operations performed over the internet are subject to the security measures implemented by the relevant service providers.
14. User Rights
Depending on applicable law, users may have rights to request information, correction, deletion, restriction of processing, or objection regarding their personal data.
Information stored locally on the device may be deleted by uninstalling the App, clearing the App’s data, or using available reset options.
Requests concerning information submitted through support communications may be sent to:
Users in Türkiye may exercise their rights under Turkish Personal Data Protection Law No. 6698 to the extent applicable.
For information processed by Google for advertising or authentication purposes, users may need to use Google’s privacy and account-management tools.
15. Changes to This Privacy Policy
If online accounts, cloud saving, multiplayer communication, additional advertising providers, new analytics services, or other data-processing features are introduced in the future, this Privacy Policy will be updated.
The latest version will be published on this page, and the “Last updated” date will be revised accordingly.
