Chess is provided by Keshav Budhiraja, trading as Puzzler Games (“we”, “us”, or “our”). This Privacy Policy applies to the Chess Android app, package name com.puzzlergames.chess, and related support communications. Our operator and contact details are set out in section 14.
This Policy explains how information is handled when you use Chess or contact us about the game. Website browsing is covered by the separate website privacy notice available at puzzlergames.online.
You can play without creating an account. Core game progress is stored on your device. Advertising, Google Play purchases, automatic crash reporting, and analytics involve additional information, as explained below.
For privacy questions or requests, contact gamespuzzler79@gmail.com.
1. Information stored on your device
Chess saves information needed to run the game and remember your choices. Depending on the features you use, this includes current game state and move history; selected game mode and computer difficulty; match results, statistics, trophies, achievements, Trophy Road and puzzle progress; tutorial and learning progress; hint balance and rewarded-hint status; sound, haptics, language, piece style, Safe Mode, Reduced Motion, presentation settings, and privacy preferences; advertisement timing; acceptance of the Terms; and purchase entitlements and processed purchase tokens.
Chess does not provide a player account or an account-based cloud save, and we do not receive local gameplay information merely because it is saved on your device. Android, device-transfer, or Google backup features may back up or restore some app data according to your device and account settings.
Normal gameplay does not ask for your name, email address, date of birth, or a public profile. Chess has no public chat or direct messaging. The app does not request access to your contacts, camera, microphone, or precise device location. Advertising services may estimate general location from an IP address.
2. Advertising and privacy choices
Chess is supported by advertising provided through Google AdMob. The game may display banners, interstitial advertisements at natural breaks, and optional rewarded advertisements. A rewarded advertisement may provide the benefit described in the game after the advertising provider confirms completion. You may decline a rewarded advertisement without losing access to core gameplay.
Google's advertising software and participating advertising partners may automatically collect, use, and share information including:
- Your IP address and an estimate of your general location.
- Advertising identifiers, app-set identifiers, and other applicable device or account-related identifiers.
- App and advertisement interactions, such as launches, impressions, clicks, video views, and reward-completion events.
- Technical, diagnostic, and performance information about the app, device, and advertising software.
This information supports ad delivery, personalisation where permitted, performance measurement, frequency limits, security, and detection of fraud or invalid traffic. Device identifiers can constitute personal information even when they do not include your name.
Chess integrates Google's User Messaging Platform to request and manage advertising consent and other privacy choices where required. Where the in-game Privacy Choices option is available, you can use it to review or change the choices provided for your region.
Personalised advertising is subject to applicable consent and age-related requirements. Declining personalisation does not necessarily remove advertising. Non-personalised or limited ads may be shown instead, where available and permitted, and may still involve information used for delivery, measurement, security, or fraud prevention.
Advertising choices do not disable the separate crash reporting described below. Accepting the Terms of Service is not, by itself, consent to data processing that requires separate consent.
Google explains its practices in its Privacy Policy and How Google uses information from sites or apps that use its services.
3. Crash reporting, diagnostics, and analytics
Chess uses Firebase Crashlytics to receive reports when the app crashes or experiences an application-not-responding event. Crash reporting is enabled by default. You can turn it off or on using the Crash reports control in Settings. Turning it off does not prevent you from playing Chess.
Diagnostics may include crash or ANR stack traces, relevant application and process state, app and Android versions, device model and configuration, a Crashlytics installation UUID, a Firebase installation ID, and Firebase session information. Related Firebase Installations and Firebase Sessions services process technical information needed to support reliability reporting.
Chess may attach limited technical context: the current screen, game mode, rules mode, computer difficulty, match number, Safe Mode state, piece style, Reduced Motion state, app version, and last high-level lifecycle event. We do not deliberately attach move history, board positions, hint balances, player progression, support correspondence, a name, an email address, or a Firebase user ID. We do not use Crashlytics reports to create advertising profiles.
We use diagnostics to investigate failures, improve stability, and support the game. Firebase explains its processing and retention in Firebase Privacy and Security.
Turning off Crash reports disables automatic submission under that setting; it does not delete information already submitted. The SDK may retain unsent reports on your device, and those reports may be submitted if reporting is enabled again. Restarting the app allows a changed reporting setting to take full effect. This control does not affect information processed separately for advertising, consent, or purchases.
Analytics and gameplay telemetry
Chess integrates Google Analytics (Firebase Analytics) to help us understand player engagement, improve game balance, and guide product improvements. Analytics is enabled by default. You can turn it off or on at any time using the Analytics control in Settings.
When Analytics is enabled, Google may collect technical identifiers (such as an app-instance identifier) and app event telemetry. In Chess, logged events include high-level gameplay actions: screen views, match starts and completions, selected game mode and computer difficulty, puzzle attempts and completions, tutorial lesson completions, hint usage, rewarded ad watch events, in-app purchases initiated or completed, and celestial ceremonies. Analytics does not collect your name, email address, contact lists, precise location, or chat messages.
We use this aggregated and event-level information to evaluate feature adoption, balance difficulty levels, measure retention, and improve stability. Google Analytics data is processed under Google's terms and privacy practices, described in the Google Privacy Policy and Firebase Privacy and Security.
Turning off Analytics in Settings immediately prevents further analytics event collection from your device. It does not affect gameplay or separate advertising, consent, or crash-reporting settings. Firebase Authentication is not enabled in Chess.
4. Google Play purchases
Where offered, Chess provides optional one-time in-app purchases through Google Play: a permanent Remove Ads entitlement and consumable packs of 10, 50, 135, or 250 hints. These products are not subscriptions. Product availability and the price shown by Google Play may vary by country, currency, account, device, and store configuration.
Google Play processes payment credentials, authorisation, currency conversion, tax, receipts, refunds, and related payment operations under Google's terms and privacy practices. Chess does not ask for or receive your full payment-card number, bank-account details, or Google account password.
The app receives product details and purchase information needed to check purchase state, grant content, acknowledge or consume a purchase, prevent a purchase token from being granted twice on the same local installation, and restore an eligible Remove Ads entitlement. This information can include the product identifier, localised price, purchase state, purchase token, acknowledgement or consumption status, and store response information. Chess stores the resulting entitlement, hint balance, and processed purchase tokens locally on the device; it does not send them to a Puzzler Games account or purchase-verification server.
Remove Ads removes banners and forced interstitial advertisements after the entitlement is confirmed. Optional rewarded advertisements remain available when you choose to use them. Remove Ads can be restored with the purchasing Google Play account. Hint packs are consumed so they can be purchased again; consumed hint packs are not restorable, and the remaining hint balance is device-local progress.
A purchase does not change your advertising consent choices or delete information already processed. If you contact support about a purchase, you may choose to provide the purchase date and Google Play order reference. Do not send full card or bank details.
5. Sharing
Chess may prepare achievement or result content for sharing through Android's system share interface. Sharing happens only when you choose it and select a destination. We do not receive the shared content merely because you open the share interface. The selected destination handles information under its own terms and privacy policy. Chess does not access your contacts to send invitations.
6. Information you send to support
If you email us, we receive your email address, message, and any attachments or other details you choose to provide. We use them to answer your request, investigate issues, address privacy or purchase questions, maintain necessary records, and prevent abuse.
Please send only information relevant to your request. Do not send passwords, full payment-card or bank details, government identity numbers, or identity-document images unless a specific, lawful verification process has been explained to you.
7. Purposes and legal grounds
We use the information described in this Policy to provide gameplay and requested features, preserve local progress and preferences, manage purchases and rewards, deliver and measure advertising, manage privacy choices, investigate and fix reliability issues, evaluate feature usage and gameplay balance to improve the game, answer support requests, protect services against misuse, and meet legal obligations.
Where applicable law requires a legal basis, the basis depends on the activity:
- Providing a requested service or performing a contract: information necessary to deliver game features, provide or restore purchases, or handle related support.
- Consent: advertising or other processing for which consent is required. Consent may be withdrawn through the relevant control or by contacting us, without affecting processing lawfully carried out before withdrawal.
- Legitimate interests, where recognised and permitted: proportionate reliability diagnostics, gameplay telemetry and product improvement, security, fraud prevention, and support administration, taking account of your rights and reasonable expectations. This basis does not replace consent where consent is legally required.
- Legal obligations: records or disclosures required to comply with applicable law or lawful requests.
Where a different local framework applies, we rely on the grounds permitted by that framework. We do not use game information to make automated decisions producing legal or similarly significant effects about you.
8. Who receives information
Information may be processed by Google through AdMob, User Messaging Platform, Google Play, Firebase Crashlytics, Firebase Installations, Firebase Sessions, and Google Analytics according to the features and choices described above. Participating advertising providers and the providers handling support email may also receive relevant information.
Some providers process information on our behalf under service and data-processing terms. Others, including providers of certain advertising and store services, determine their own purposes and practices. Their policies explain those activities. Using a third-party service does not remove our responsibilities for processing for which we are responsible.
We may disclose information where reasonably necessary to comply with law, respond to a valid legal request, investigate fraud or abuse, or establish, exercise, or defend legal rights. If the game or its business is transferred, information necessary for the transfer may be shared with the successor subject to appropriate safeguards and any required notice.
We do not sell local Chess progress, support correspondence, crash-reporting records, or analytics records. Advertising-related disclosures of identifiers and interaction information may, however, qualify as a “sale”, “sharing”, or processing for targeted advertising under some privacy laws, even without direct payment for the information. Where those laws apply, you can exercise relevant choices through available advertising privacy controls or contact us.
9. International processing
We are based in India. Google and other providers may process information in other countries, including the United States, where privacy laws may differ from those where you live.
Where cross-border transfer rules apply, transfers must use the required safeguards, such as an applicable adequacy decision, approved contractual protections, or another legally recognised mechanism. Relevant provider terms explain their transfer arrangements. Contact us for information about safeguards applicable to processing for which we are responsible.
10. Retention and deletion
We retain information only for as long as reasonably necessary for the purposes described in this Policy or applicable legal requirements:
- Local game information: remains until replaced or reset through gameplay, app storage is cleared, or the app is uninstalled. An Android, device-transfer, or Google backup may persist separately and must be managed through the applicable device or account controls. Chess has no account-based cloud save from which we can recover progress.
- Crash reports and analytics: Firebase currently describes a 90-day period for crash stack traces and associated identifiers before removal from live and backup systems begins. Google Analytics event data is retained according to standard Google Analytics retention periods before automated removal. Other Firebase operational information may follow different retention rules.
- Advertising, consent, and purchase information: retention depends on the relevant provider's role, service rules, consent records, and applicable accounting, security, fraud-prevention, or legal requirements.
- Support correspondence: kept while needed to resolve the issue, maintain necessary records, address disputes, and meet legal obligations, then deleted or anonymised when no longer needed.
Uninstalling the game, resetting an advertising identifier, or switching off a feature does not automatically erase information already held by a provider. We will address valid deletion requests within our responsibilities and explain any lawful limits or records that must be retained.
11. Your controls and privacy rights
You can manage advertising choices through Privacy Choices, where available; turn Crash reports and Analytics off or on in Settings; decline optional rewarded advertisements; manage supported advertising-identifier controls in Android settings; choose whether to make a purchase or share content; restore an eligible Remove Ads entitlement; and clear local app storage or uninstall Chess. Clearing storage or uninstalling can permanently remove local progress and unspent hints.
Depending on your location and the law applicable to the processing, you may also have rights to access information, correct it, request deletion, obtain a portable copy, restrict or object to processing, withdraw consent, or opt out of certain advertising-related disclosures. Where applicable, you may use an authorised agent, appeal a decision about a request, or complain to the relevant data-protection authority. We will not penalise you merely for exercising a protected privacy right.
Send requests, complaints, or appeals to gamespuzzler79@gmail.com. Describe your request and relevant country or region. We may ask for proportionate information to verify the request or locate the relevant record. Because Chess has no account system, we may not be able to associate a technical record with you without additional information. We will not collect unnecessary identity information solely to create that association.
We respond within the periods required by applicable law and explain any lawful refusal or limitation. Where a provider independently controls information, we may direct you to its request process and assist as appropriate.
12. Age-related privacy
Chess is intended for people aged 13 and older and is not directed to children under 13. The app has no account registration, public profile, chat, or in-game form requesting a player's name, email address, or date of birth. Chess does not knowingly ask a child under 13 to provide personal information.
People aged 13 to 17 may still be minors, and a higher minimum age or parental authorisation requirement may apply where they live. If applicable law requires permission from a parent or legal guardian, the game may be used only after that permission has been provided. The 13+ audience statement does not override local law, platform rules, or required consent and safeguarding measures.
Google advertising, diagnostic, and store services may process technical, device-related, advertising, and purchase information as described in this Policy. We do not knowingly use a child's personal information for targeted advertising where prohibited by law.
If you believe information relating to a child has been processed without required authorisation or contrary to applicable protections, contact gamespuzzler79@gmail.com. We will review the concern and take the action required in the circumstances, including deletion or restriction of relevant information and coordination with service providers where necessary.
13. Security
We use reasonable technical and organisational measures appropriate to the information and processing involved. Game data uses Android app storage, and connected Google services use encrypted transmission. No device, storage system, or transmission method can be guaranteed completely secure. Please protect access to your device and keep your device and app up to date.
14. Changes and contact
We may update this Policy as the game, our practices, or legal requirements change. The latest version will be available through the in-app legal copy and on the Chess website, with an updated date. For material changes, we will provide additional notice where required and obtain fresh consent where necessary. Publishing an updated policy does not itself provide consent for new processing.
