This policy explains how information is handled in the current Google Play release of Yes Button for Android. The app provides sound buttons for entertainment. It does not offer account registration or an app login.
Sounds and animations are included in the app. Sound playback uses local assets. The app does not record your microphone, upload audio, or request access to contacts, your photo library or precise location. We do not operate a server that receives your sound selections or playback history.
The app stores selected sounds and settings on your device. It also keeps purchase receipts and PRO entitlement information in app-private storage as described below. A complimentary PRO access code is checked locally: the raw code is not transmitted to us, and a local authorization value is saved when redemption succeeds. You can remove complimentary access through the same in-app entry.
Optional PRO access is offered through a one-time purchase or monthly or yearly auto-renewing subscriptions. Google Play processes payment and payment-account information under its own terms and privacy policy. The app does not receive your payment card details.
The app receives purchase records such as product identifiers, purchase tokens, purchase status, purchase time and receipt signatures. These records are used to verify and acknowledge purchases, unlock PRO, restore purchases and prevent fraudulent access. Verified receipts, entitlement state and the time of the last successful purchase check are cached on your device. The current implementation does not send receipts to a developer-operated verification server.
Using the same Google Play account, you can restore eligible purchases on another Android device. App Store and Google Play purchases are separate. Uninstalling the app or clearing local data does not cancel a subscription or delete Google's transaction records. Manage or cancel Google Play subscriptions at Google Play subscriptions.
The current release does not include Google Mobile Ads, Google's User Messaging Platform, Google Analytics for Firebase or Crashlytics, and does not display third-party advertisements or access the Android advertising ID. This does not mean that no third-party processing occurs.
The Google Play Billing library and its data transport components can collect and send Google usage and diagnostic information, including billing API interactions, results and errors, exceptions, performance timings, a randomly generated SDK session identifier, app and SDK versions, package name, Android version, device model and brand, system and memory information, language, region settings, time zone, network type and mobile carrier codes. Google may receive the IP address used for network communication. Region settings and carrier codes are not precise location coordinates.
Google processes this information for SDK operation, reliability, diagnostics and analytics under its own privacy practices. Diagnostic events may be queued in local app storage before transmission; they are not necessarily processed only momentarily. These SDK transmissions are separate from our handling of purchase records. We do not operate a separate analytics server. See the Google Privacy Policy.
The Share App action sends an app-store link through the Android share sheet to the app you choose. It does not share sound recordings or purchase receipts. External browser pages, Google Play and receiving apps follow their own privacy practices.
If you email us, we receive your email address, message, attachments and other information you choose to provide. We use this information to respond, troubleshoot and handle privacy requests. Please do not send passwords, payment card details or unnecessary sensitive information. Our contact mailbox is provided through Microsoft Outlook; see the Microsoft Privacy Statement.
We use information for app functionality, purchase verification and restoration, fraud prevention, technical support and applicable legal obligations. Google's SDKs also process usage, diagnostic and session information for analytics and service reliability. We do not sell your personal information. Information is handled by Google for billing and SDK services, Microsoft for email, and a receiving service when you choose an external link or share action. Relevant correspondence may also be disclosed where required by a valid legal request or necessary to protect legal rights.
Where applicable law requires a legal basis, processing relies on providing the service or purchase you request, legitimate interests in security and reliability, compliance with legal obligations, or consent where required. Reading this policy does not replace affirmative consent where consent is required.
Local settings, cached receipts, SDK queues and complimentary access state remain until replaced, cleared through Android app-storage controls or removed when you uninstall the app. SDK queue entries may also be removed after delivery or expiration under SDK rules. Clearing data resets your local selections and complimentary access. It does not cancel or refund a Google Play purchase.
We retain support and privacy correspondence for the time needed to handle requests and follow-up, resolve relevant disputes and meet applicable retention obligations. We delete records under our control when those purposes no longer apply. Google and Microsoft apply their own retention practices. Uninstallation does not automatically erase provider records.
To request access, correction or deletion of information under our control, email marsgroupapp@outlook.com with the app name and a description of your request. We may ask for information reasonably needed to locate and verify the relevant records. We cannot directly delete records independently held by Google, Microsoft or another service.
You can choose whether to buy PRO, manage subscriptions through Google Play, remove complimentary access, clear app data or uninstall the app. There is no app account to delete.
Depending on applicable law, you may have rights to access, correct, delete or receive a copy of personal information, restrict or object to processing, withdraw consent, or complain to a data protection authority. These rights may have exceptions. Withdrawal of consent does not affect earlier lawful processing. Contact our privacy address to make a request or raise a concern.
The app is intended for users aged 13 and above and is not directed to children under 13. We do not knowingly request personal information from children under 13. If you believe a child has provided personal information to us, contact marsgroupapp@outlook.com. We will review and address information under our control. Minors should use the app and make purchases with appropriate parent or guardian involvement.
Settings and cached purchase records use Android app-private storage; the app disables Android backup for its data and disallows cleartext network traffic. No storage or transmission method guarantees absolute security.
Google and Microsoft operate internationally and may process information outside your country. Privacy laws may differ between locations. Their policies describe applicable safeguards. See Google's international data transfer information.
We may update this policy when app features, services or applicable requirements change. The updated policy will show its effective date. We will provide additional notice or request consent where required before affected processing begins. If advertising is introduced in a future release, we will update the relevant policy and disclosures before that processing begins.
