Request deletion of your data (Mochi Mochi Donuts)

This section applies to Mochi Mochi Donuts on Google Play and on the Apple App Store, published by Michael Piercy / Game Design. The App does not create its own user accounts.

How to request deletion

Email gamedesign.ie@gmail.com with the subject line “Mochi Mochi Donuts data deletion request”.
Say whether you play on Google Play or the App Store, and confirm that the request is for Mochi Mochi Donuts.
If you signed in with Play Games, include your Play Games display name and, if you know it, your Play Games player ID. If you use Game Center, include your Game Center display name.
For an Ad-Free Play purchase, include the store and the approximate purchase date. The anonymous install id used for that record stays on your device and is not shown in the App, so we can delete only the purchase records we can reasonably match.
We may ask a short follow-up question to verify that you control the relevant store identity before deleting data.
After verification, we will delete the App cloud data described below and confirm by email when complete.

We aim to complete verified requests within 30 days (sooner where required by applicable law).

Data we delete on request

Cloud collection / unlock progress stored for a Play Games player identity
Cloud gameplay / game-event records we store for that Play Games player identity
Related profile sync records we hold on our Google Cloud / Firestore backend for that Play Games player identity
Ad-Free Play purchase records held for us by RevenueCat, where we can match them to your request

Data that is not deleted by this request (or that we do not control)

On-device App data — on Android, clear App storage or uninstall the App. On Apple platforms, delete the App. That removes local progress, settings, and the anonymous install id from the device.
Your Google / Play Games account — we cannot delete your Google account. Manage or delete that account through Google.
Your Apple ID or Game Center account — we cannot delete those. Manage them through Apple.
Payment records held by Google Play or Apple — manage purchases and subscriptions in the store account you used.
Advertising data processed by Google AdMob and partners — managed through your device ad settings and Google’s privacy controls; see Google’s privacy policy.
Data we must keep temporarily for legal, security, fraud-prevention, or dispute reasons — if applicable, only for as long as needed, then deleted or anonymised.

Retention after a deletion request

Once a verified request is completed, the deletable cloud data above is removed from our active systems. Residual copies may remain in encrypted backups for up to 90 days before those backups are rotated or purged, and are not used to restore your App profile.

3. Information we process

Depending on how you use the App, which store you installed it from, and your device settings, the following categories of information may be processed.

3.1 Information stored on your device

Local game settings and preferences
Local collection / unlock progress and scores
Ad-Free Play entitlement, if you purchased one
An anonymous install id used only if a purchase is recorded with RevenueCat
Other gameplay state needed to run the App offline

This on-device data stays on your device unless a cloud feature below is enabled and used. On Apple platforms, collection progress is stored on the device. It is not uploaded for cloud sync.

3.2 Advertising (Google AdMob)

On Android phones and tablets, and on iPhone and iPad, the App uses Google AdMob to show banner, interstitial, and rewarded ads. The current Mac, Apple TV, and Android TV builds do not show ads.

Google and its partners may collect and process information such as:

Advertising ID (Android Advertising ID / AAID, or Apple’s Identifier for Advertisers / IDFA if you allow tracking)
IP address, which may be used to infer approximate location
Device and app diagnostic information, including crash logs that are not tied to you and performance data such as launch or hang information
Ad interaction data (for example impressions, clicks, and video views)
Other identifiers used for advertising, measurement, and fraud prevention

Where required (for example in the EEA, the UK, or Ireland), we present a consent experience using Google’s User Messaging Platform (UMP) before personalised ads are requested.

On iPhone and iPad, Apple shows an App Tracking Transparency prompt. If you tap Ask App Not to Track, we do not use the IDFA for personalised ads. Non-personalised ads may still appear.

Find out more about Google’s practices: Google Privacy Policy and How Google uses information from sites or apps that use our services.

You can reset or limit your advertising identifier in Android or Apple system privacy settings.

3.3 Google Play Games (Android, optional)

On Android, the App may offer Google Play Games sign-in. If you sign in, Google may provide us with identifiers such as a Play Games player ID and display name so we can authenticate you and restore progress.

Play Games is provided by Google. Use of Play Games is also subject to Google’s terms and privacy policy.

3.4 Cloud progress on Android

When Play Games sign-in and cloud sync are available and active, the App may send limited gameplay-related data to our backend services hosted on Google Cloud (including Cloud Functions and Firestore), for example:

Play Games player identifiers needed for authentication
Collection unlock / progress data
Game completion or related gameplay event records used for sync and stats

We use this information to sync progress across sessions and devices on Android, support Play Games features, and operate the App reliably. We do not use this data to sell ads ourselves. This cloud sync is not part of the Apple builds.

3.5 Game Center (Apple, optional)

On iPhone, iPad, Mac, and Apple TV, you can use Game Center. If you do, Apple may provide a Game Center player ID and display name so the App can submit scores and achievements. Game Center is provided by Apple and is also subject to Apple’s privacy policy. It is not required to play.

We do not send your Game Center player ID or display name to our own servers. Collection progress on Apple platforms stays on the device.

3.6 In-app purchases

Ad-Free Play is optional. It is a monthly subscription, an annual subscription, or a one-time 7-day pass. Google Play sells it on Android. Apple sells it on iPhone, iPad, Mac, and Apple TV. The store processes the payment. We do not receive your card details.

After a purchase or restore, the App sends the store receipt (on Apple) or purchase token (on Android), the product id, and an anonymous install id to RevenueCat. That id is created on the device. It is not your name, email address, or Game Center or Play Games id. We use it to record Ad-Free Play so banner and interstitial ads can be hidden. Optional rewarded ads may still be offered after purchase. RevenueCat does not use this purchase record to track you across other companies’ apps.

3.7 In-game notices

On Android, iPhone, and iPad, the App may request a list of in-game notices from our backend. That request includes the platform (for example android or ios) and a build number. It does not include your name, advertising id, or Game Center or Play Games player id.

3.8 Permissions

The Android App may request or declare:

Internet — to load ads, record purchases, fetch notices, and sync cloud features
Advertising ID (AD_ID) — used by the ads SDK for advertising and measurement

On iPhone and iPad, the App may request:

App Tracking Transparency — permission to use the advertising identifier for personalised ads. You can refuse.

The App does not ask for your contacts, photos, camera, microphone, or precise location.

4. How we use information

We use the information described above to:

Operate, maintain, and improve the App
Show ads and measure ad performance, on the devices where ads run
Provide optional Play Games sign-in and cloud progress sync on Android
Provide optional Game Center scores and achievements on Apple platforms
Honour Ad-Free Play
Detect abuse, fraud, and technical issues
Comply with legal obligations and store requirements

5. Sharing of information

We may share information with:

Google (AdMob, Play Games, Google Cloud / Firebase infrastructure) — as needed to provide ads, Android authentication, hosting, and related services
Apple (App Store, Game Center, and StoreKit) — when you use those features or make a purchase
RevenueCat — the purchase receipt or token, product id, and anonymous install id, so we can record Ad-Free Play
Service providers who process data on our behalf solely to help us operate the App
Authorities if required by law, regulation, or valid legal process

We do not sell personal information. Advertising partners may receive data as described in Section 3.2 in connection with serving and measuring ads.

6. Data retention

On-device game data remains until you clear app data or delete the App.
Cloud progress and event data associated with a Play Games account is retained while needed to provide sync, or until we delete it as part of routine maintenance or a verified deletion request.
Game Center scores and achievements are retained by Apple under Apple’s policies.
Ad-Free Play records held by RevenueCat are retained while needed to record the purchase, or until we delete a record we can match to a verified request.
Advertising and diagnostic data retained by Google is governed by Google’s policies.

7. Security

We take reasonable technical and organisational measures to protect information we process, including transmitting cloud sync and purchase records over HTTPS. No method of transmission or storage is completely secure.

8. Children’s privacy

The App is intended for a general audience. It is not directed at children under 13 (or the equivalent minimum age in your country), and we do not knowingly collect personal information from children for our own independent profiling.

Because the App includes advertising on Android phones and tablets and on iPhone and iPad, parents and guardians should review device settings and supervise use by minors. If you believe a child has provided personal information to us inappropriately, contact us and we will take reasonable steps to delete it.

9. Your choices and rights

Play without Play Games and without Game Center
On iPhone or iPad, tap Ask App Not to Track, and reset or limit the advertising identifier in system settings
On Android, reset or limit your advertising ID in system settings
Manage Play Games sign-in from your Google account / Play Games settings
Manage or cancel Ad-Free Play in Google Play or in your Apple ID subscriptions
Clear local App data or delete the App
Use any in-app or regional consent controls presented for ads (including UMP where shown)

Depending on where you live (for example Ireland, the EEA, the UK, or certain US states), you may have rights to access, correct, delete, or restrict certain processing of personal data, or to object to certain processing. To request deletion of App cloud data we control, follow the steps in Request deletion of your data. For other privacy requests, email gamedesign.ie@gmail.com. For data processed by Google or Apple, you may also need to use that company’s own tools and account settings.

10. International processing

Information may be processed on servers outside your country of residence, including by Google, Apple, RevenueCat, and Google Cloud infrastructure. Where required, we rely on appropriate safeguards used by those providers.

11. This website

The website at mochimochidonuts.com is a simple static site used to publish information and policies about the App. It does not use cookies, analytics, or advertising trackers.

12. Changes to this policy

We may update this Privacy Policy from time to time. The “Last updated” date at the top will change when we do. Continued use of the App after an update means you accept the revised policy.
