Privacy Policy

This Privacy Policy applies to the mobile application 2D Rubik's (Android package name com.varlextech.twodrubiks, the "App"), developed and published by Varlextech Limited ("Varlextech Limited", "we", "us", or "our"). It explains what information the App handles, how it is used, the third-party services integrated into the App, and the choices you have.

By installing or using the App, you agree to the practices described in this policy. If you do not agree, please do not use the App.

1. Summary

• 2D Rubik's stores your game progress locally on your device only. Varlextech Limited operates no game servers and does not itself collect, transmit, or store your personal data.
• The App shows advertising via Google AdMob and processes optional in-app purchases via Google Play Billing / Apple StoreKit. These third-party SDKs may collect device and usage data under their own privacy policies, as detailed in Section 4.
• You can delete all data the App stores by clearing the app's storage or uninstalling it.

2. Information stored on your device

2D Rubik's saves the following data locally on your device (in app-private storage) so the game can function and remember your progress:

• Game progress — unlocked levels, stars earned per level, daily challenge streak, and endless-mode best run.
• Settings — sound/music mute, colour theme, and symbol overlay preferences.
• Virtual items — your "hints" balance (earned via rewarded ads or purchased hint packs).
• Purchase entitlements — a flag recording whether the "Remove Ads" purchase is active.

This data never leaves your device and is not accessible to Varlextech Limited. It is deleted when you clear the App's data or uninstall the App.

3. Information Varlextech Limited does not collect

We do not ourselves collect, request, or have access to:

• Your name, email address, phone number, or contacts
• Account credentials (the App has no sign-up or login)
• Precise location, photos, microphone, camera, or files
• Payment card details (all payments are processed by the app store)
• Any analytics or telemetry — the App includes no Varlextech Limited-operated analytics, tracking, or crash-reporting service

4. Third-party services

The App integrates the following third-party services. Each acts as an independent data controller and processes data under its own privacy policy.

4.1 Google AdMob (advertising)

2D Rubik's displays banner, interstitial, and opt-in rewarded ads provided by Google AdMob (Google LLC). To serve and measure ads, prevent fraud, and cap frequency, the AdMob SDK may collect and process:

• Device identifiers, including the Android Advertising ID (AAID) or iOS Identifier for Advertisers (IDFA, only where you grant App Tracking Transparency permission)
• IP address, from which coarse (city-level) location may be inferred
• Device and app information (model, OS version, screen size, app version)
• Ad interaction data (impressions, taps, rewarded-ad completions)
• Diagnostic and crash data related to the ad SDK

Personalized vs. non-personalized ads. Where required (e.g., in the EEA, UK, and Switzerland), consent for personalized advertising is requested through Google's User Messaging Platform (UMP) consent flow the first time you open the App, and can be changed at any time via your device or the consent options presented in the App. On iOS, the App requests App Tracking Transparency authorization before any tracking. You can also limit ad personalization globally via your device's advertising settings (Android: Settings → Privacy → Ads; iOS: Settings → Privacy & Security → Tracking), or reset/delete your Advertising ID.

4.2 Google Play Billing / Apple StoreKit (payments)

Optional in-app purchases ("Remove Ads" and hint packs) are processed entirely by Google Play (on Android) or the App Store (on iOS) under the store's own terms and privacy policies. The App receives only a purchase token and product identifier from the store SDK in order to unlock the purchased item; Varlextech Limited never sees or stores your payment card information.

• Google Play Terms: https://play.google.com/about/play-terms/
• Apple Media Services Terms: https://www.apple.com/legal/internet-services/itunes/

5. How information is used

• Core gameplay — saving progress, stars, streaks, settings, and hint balance on your device.
• Advertising — displaying ads, measuring ad performance, and preventing ad fraud (AdMob).
• Purchases — completing transactions, granting purchased items, and restoring purchases across reinstalls (app stores).

For users in the EEA/UK, the legal bases are: performance of the contract (providing the game and purchases you request), legitimate interests (fraud prevention and non-personalized advertising), and your consent (personalized advertising, where requested).

6. Data sharing and sale

Varlextech Limited does not sell your personal information and does not share data with third parties for their own marketing. The only disclosures are the automatic transmissions made by the embedded SDKs listed in Section 4, which are necessary to show ads and process purchases. Under some US state privacy laws (e.g., California's CCPA as amended by the CPRA), sharing an advertising identifier with an ad network for personalized advertising may be considered "sharing" for cross-context behavioral advertising — you may opt out as described in Section 8.

7. Data retention and deletion

All data the App stores itself remains only on your device and is erased when you clear the App's storage or uninstall it. Third-party providers retain the data they collect for the periods described in their own privacy policies. You may also contact us at varlextechltd@gmail.com to request deletion of any data held about you by our providers, and we will forward or action the request as appropriate.

8. Your rights and choices

Depending on where you live, you may have rights over your personal data, including the right to access, correct, delete, restrict or object to processing, data portability, and to withdraw consent.

• Delete your data: uninstall the App or use "Clear data"/"Clear storage" in your device's app settings — this removes all locally stored progress and settings.
• Control ad personalization: use the consent options in the App (EEA/UK), your device's advertising settings, or reset your Advertising ID at any time.
• Opt out of "sharing"/sale (US states): we do not sell personal data; to opt out of any ad-identifier sharing, disable ad personalization in your device settings or decline consent in the App's consent dialog.
• Purchases: restore purchases via the App's Store → "RESTORE", or through your app store account.
• Contact us: for any privacy request (access, deletion, questions), email varlextechltd@gmail.com. We respond within a reasonable time and will not discriminate against you for exercising your rights.

EEA/UK users may also lodge a complaint with their local data protection authority.

9. Children's privacy

2D Rubik's is intended for a general audience and is not directed at children under 13 (or the applicable age of digital consent in your region). We do not knowingly collect personal information from children. If you believe a child has provided personal information through the App's third-party services, please contact us at varlextechltd@gmail.com and we will work with the relevant provider to delete it.

10. Security

Because all game data is stored locally on your device and Varlextech Limited operates no servers, the primary safeguard is your device's own security (device lock, OS sandboxing). The third-party SDKs used by the App transmit data over encrypted (HTTPS/TLS) connections. No method of transmission or storage is 100% secure, but we select reputable providers and minimize data collection by design.

11. International data transfers

Third-party providers such as Google may process data on servers located in the United States and other countries. Where required, such transfers are covered by the safeguards described in those providers' privacy policies (e.g., Standard Contractual Clauses or adequacy frameworks).

12. Changes to this policy

We may update this Privacy Policy from time to time. Any changes will be posted at this URL with an updated "Effective date". Your continued use of the App after changes take effect constitutes acceptance of the revised policy.
