We act as the data controller for personal data processed through our website and games, unless specified otherwise in relation to third-party SDK processing (such as Google AdMob).

This policy covers all currently published and future Android games and applications distributed by Sahasra Tech on Google Play. Each game has a dedicated policy breakdown detailing its exact permissions and data collection:

Depending on the game and your interactions, you may choose to provide us with certain information directly:

When you download, open, or play our mobile games, certain diagnostic and technical information is automatically collected by our apps or integrated Google SDKs:

• Device Information: Device model, hardware manufacturer, operating system version (e.g. Android 13/14), system language, and screen resolution.

• General Network Metadata: IP address (used for geolocation at country/city level and network diagnostics; IP addresses are truncated or anonymized in analytics).

• App Performance & Diagnostics: Crash stack traces, app launch times, memory warnings, freeze events, and ANR (Application Not Responding) metrics via Firebase Crashlytics.

• Gameplay & Engagement Events: Aggregated gameplay statistics such as levels completed, puzzles solved, game duration, and session frequency via Firebase Analytics.

Key Point: Our free-to-play games are supported by Google AdMob advertising. Here is how advertising data is handled.

We use Google AdMob (Publisher ID: pub-1898348928673459) and Google Mobile Ads SDK to serve banner, interstitial, and rewarded video advertisements in our free-to-play mobile games.

AdMob may collect and process the following data to serve, measure, and protect against fraudulent ad clicks:

• Google Advertising ID (GAID / AAID) on Android devices.

• Coarse location inferred from IP address.

• Device identifiers and diagnostic information.

• Interaction data with advertisements (impressions, clicks, completed rewarded video views).

Consent & Personalization:

In regions where user consent is legally required (including the European Economic Area (EEA), United Kingdom, and Switzerland under GDPR/ePrivacy), our games display a Google-certified User Messaging Platform (UMP) consent dialog. Players can accept or refuse personalized advertising or configure choices vendor-by-vendor.

In non-EEA jurisdictions, you can reset or delete your Advertising ID at any time via Android Settings → Google → Ads → 'Reset advertising ID' or 'Delete advertising ID'.

Official reference: You can review Google's advertising privacy disclosures at https://policies.google.com/technologies/ads and https://developers.google.com/admob/android/privacy.

We utilize Google Firebase SDKs (Firebase Analytics and Firebase Crashlytics) to monitor application stability and improve user experience.

• Firebase Analytics: Helps us understand player engagement, popular game modes, and user retention in an aggregated format. It uses an instance ID generated when the app is installed, which does not identify you personally.

• Firebase Crashlytics: When an unexpected error occurs, Crashlytics captures technical stack traces, device state (memory and battery level), and thread traces so our engineers can patch bugs quickly. No sensitive data or passwords are transmitted in crash dumps.

Data retention in Firebase Analytics is set to standard rolling retention windows (typically 2 to 14 months for event-level data). For more details, consult https://firebase.google.com/docs/android/play-data-disclosure.

We believe in frictionless gameplay. The vast majority of our games (such as 2048!™, Uno Offline, Snake Game Offline, Water Puzzle, Cake Tower 3D, and Puzzle Block) do NOT require any user account or registration whatsoever. Your high scores and progress remain 100% on your device.

For titles that support multiplayer matchmaking or cloud features (such as Tichuk Tayo and Uno Classic):

• Guest Player Mode: You can play as a guest without linking an email or social account. A randomized guest player ID is assigned locally.

• Optional Profile: If you choose to set a custom username or join clans, we store only your selected nickname, clan affiliation, and matchmaking rank.

• Multiplayer Records: Room IDs, game turn payloads, and match outcomes are processed temporarily to coordinate live matches. We do not sell or share in-game player records.

Select Sahasra Tech games offer optional in-app purchases (such as ad removal, hints, or cosmetic items).

All financial transactions and payments are processed exclusively through Google Play's secure billing system (Google Play In-App Billing).

Sahasra Tech NEVER receives, processes, or stores your credit card number, debit card details, bank account, or billing address. We only receive an anonymized purchase token from Google Play to confirm entitlement and unlock purchased features on your device.

We do not sell, rent, or trade your personal data. We only share information with third-party service providers who assist us in operating our games, strictly under confidentiality and data protection obligations:

1. Google LLC (Google Play Services, Google AdMob, Firebase Analytics, Crashlytics, Firebase Realtime Database) — Core gaming infrastructure, advertising, and crash analytics.

2. Vercel Inc. — Hosting and serverless infrastructure for our studio website (https://sahasratech.vercel.app).

3. Authorized Ad Networks (via Google AdMob Mediation where applicable) — Listed in our public ads.txt / app-ads.txt files.

On our website (https://sahasratech.vercel.app):

• Strictly Necessary Cookies/Storage: We use browser local storage solely to remember essential preferences (such as your cookie consent selection and mobile menu status).

• We do not serve third-party advertising cookies or cross-site tracking pixels on our website.

• You can manage your website cookie preferences at any time via our dedicated page at /cookie-preferences.

Note: Website cookie preferences apply to web browsing only and do not control in-game mobile advertising (which is governed by Android OS settings and in-app Google UMP dialogs).

We retain personal data only for as long as necessary to fulfill the purposes outlined in this Privacy Policy:

• Support & Privacy Correspondence: Retained for up to 12 months after resolution to follow up on open requests, after which tickets are deleted or de-identified.

• Multiplayer Profiles: Retained while the player account remains active. Inactive accounts with no activity for 24 months are queued for automated pruning.

• Shared Levels / Temporary Game Data: Retained for 7 to 30 days and purged via automated cron jobs (e.g. /api/cron/cleanup-levels).

• Google Play Purchase Entitlements: Purchase tokens are maintained as long as needed to honor active entitlements on your device.

Key Point: We provide a public, permanent mechanism for players to request deletion of their account and associated data.

In compliance with Google Play's Account Deletion Policy, we offer two straightforward deletion paths:

1. In-App Deletion: For games with account or profile features, navigate to Game Settings → Account → 'Delete Account & Data'.

2. Web Deletion Portal: Visit our public deletion page at /delete-account. Select your game, enter your identifier (username, player ID, or email), and submit a request. You will receive a verifiable Deletion Request Ticket ID.

Deletion Process: Once identity is confirmed, account records, matchmaking statistics, and profile associations are permanently expunged within 30 days. Exceptions apply solely where retention is legally mandated (such as tax/accounting records for Google Play purchases).

We employ industry-standard administrative, physical, and electronic security measures to safeguard user information against unauthorized access, loss, alteration, or destruction:

• All web and API traffic is encrypted in transit using Transport Layer Security (TLS 1.3 / HTTPS).

• Firebase Realtime Database is protected with strict read/write security rules preventing unauthorized data dumps.

• Administrative functions are guarded with server-side secrets and authorization tokens.

While we take all reasonable precautions, please note that no method of transmission over the Internet or electronic storage is 100% impenetrable.

Our games are designed for general audiences and casual gaming enthusiasts. We do not knowingly collect personally identifiable information from children under 13 (or under 16 in the European Union).

If we discover that a child under 13 has provided personal information without verifiable parental consent, we will promptly delete that information from our servers.

Parents or legal guardians who believe their child has submitted personal data may contact us immediately at privacy.sahasratech@gmail.com with the subject 'Child Data Inquiry' for swift deletion.

Depending on your place of residence, you may possess the following legal rights regarding your personal information:

• Right to Access: Request a summary of the personal data we hold about you.

• Right to Rectification: Request correction of inaccurate or incomplete personal details.

• Right to Erasure ('Right to be Forgotten'): Request deletion of your personal data.

• Right to Restrict or Object to Processing: Object to data processing based on legitimate interests.

• Right to Data Portability: Receive your data in a structured, machine-readable format.

• California Residents (CCPA/CPRA): We do not sell or share personal information for monetary consideration. You have the right to know what categories of personal data we collect and to opt out of any potential sale or sharing.

To exercise any of these rights, visit our Privacy Support Portal at /privacy-support or email us at privacy.sahasratech@gmail.com. We will respond within 30 days at no charge.

Our games and servers operate globally through Google Cloud Platform and Firebase data centers. By using our applications, you understand that your information may be transferred to, stored, and processed in jurisdictions outside your country of residence, where data protection standards may differ.

Google LLC maintains robust contractual and organizational safeguards (including Standard Contractual Clauses approved by the European Commission) to protect cross-border data flows.

We may update this Privacy Policy from time to time to reflect modifications in our games, technologies, legal requirements, or Google Play policies. Any changes will be published directly on this page with an updated 'Last Updated' date (October 13, 2026).
