Manthan: Idle Ocean Churn, Privacy Policy

1. Who we are

Manthan: Idle Ocean Churn is an idle game published by Numford (numford.com), "we" in this policy. You can reach us at support@numford.com.

The game has no account system and no server of our own. You can play it fully offline and without signing in to anything.

2. What we collect and why

We collect as little as we can. We do not ask for your name, email address, phone number, contacts, photos or location. The game reads your advertising ID only for rewarded ads, as described in section 2.5.

2.1 Your game save

Your progress is stored on your device. Android may include this save file in your normal Google backup for your device. We do not read it.

2.2 Analytics and crash reports (only if you allow them)

The first time you open the game it asks whether to allow analytics and crash reports. If you tap "No thanks", both stay off. You can change your mind at any time in Settings, Privacy.

• Analytics (Firebase Analytics): short game events such as tutorial step reached, treasure found, how long you were away, and when the game lowers its graphics quality. Events contain numbers and short names only. They do not contain personal data. We use them to fix confusing parts of the game and to balance it.
• Crash reports (Firebase Crashlytics): the crash log, basic device information (model, Android version, memory) and app state at the time of a crash. We use them to fix crashes.

Both use a random identifier that Firebase creates for this installation of the game. It is not linked to your name or to your Google account by us.

A crash report may be stored on your device until it can be sent. If a crash happened before you allowed crash reports and you allow them later, that stored report can be sent then. If you switch Analytics off, the game also asks Firebase to reset its analytics data on your device.

2.3 Game tuning (Firebase Remote Config)

After you answer the first-launch card (with either answer), the game checks at most every 12 hours for small balance adjustments, such as how fast a bar fills. This check uses the Firebase installation ID of your device. It happens even if you turned analytics and crash reports off, because the game needs it to receive these settings. It does not send your game progress. New values are checked by the game and apply at the next launch.

2.4 Google Play Games (only if you sign in)

The game can sign you in with Google Play Games. If you sign in, Google provides us with your Play Games player ID and public profile (player name and avatar), which the game uses to:

• store and restore your saved game in the cloud (Play Games saved games);
• unlock achievements and show leaderboards, when those features are available.

Saved games are stored by Google. Leaderboard and achievement entries are visible to other players according to your Play Games settings. If you do not sign in, none of this applies and your save stays on your device.

2.5 Rewarded ads (Google AdMob)

The game offers optional rewarded ads: you choose to watch a short ad in return for a bonus. We never show ads you did not ask for. To show an ad, Google AdMob and its ad partners may collect and use your device identifiers (such as the advertising ID), IP address, device and app information and ad interactions, to deliver and measure ads, prevent fraud and, where you allow it, personalise them.

In the European Economic Area, the United Kingdom and Switzerland, the game shows Google's consent form (Google User Messaging Platform, UMP) before any ad is requested, and you can change your choice later in Settings, Privacy. Where you do not give consent, only non-personalised ad requests are made or no ad is shown, as the law requires.

2.6 Purchases (Google Play Billing)

If you buy something in the game, the purchase is processed by Google Play. Google handles your payment details; we never see your card or payment information. We receive purchase information (what was bought, order ID, purchase token and time) so we can give you the item, restore it if you reinstall, and keep a record. You can ask Google to refund a purchase through Google Play.

2.7 What we do not do

• We do not sell your personal data.
• We do not use your data for advertising profiles of our own.
• We do not collect your precise or approximate location.

4. Third-party services

These services process data for us under their own terms. We do not sell data to them.

• Google Firebase (Analytics, Crashlytics, Remote Config): firebase.google.com/support/privacy
• Google Play Games Services: policies.google.com/privacy and Play Games Services terms
• Google AdMob and UMP: how Google uses data from partner apps and AdMob data usage
• Google Play Billing and Google Play: policies.google.com/privacy

Your data may be processed in countries other than your own, including the United States, under Google's data transfer safeguards.

5. How long we keep data

• Analytics events: kept by Firebase for 2 months (the Google Analytics default) and then deleted automatically.
• Crash reports: kept by Firebase Crashlytics for 90 days.
• Remote Config: the installation ID is kept by Firebase until the app is uninstalled or its data is cleared, plus Firebase's standard deletion time.
• Play Games data: kept by Google until you delete your Play Games data or your saved game.
• Purchase records: kept as long as needed to restore purchases and meet tax and accounting law.
• Your local save: stays on your device until you uninstall the game or clear its data.

6. Children

The game is not directed at children under 13, and it is not part of Google Play's Families programme. We do not knowingly collect personal data from children under 13. If you believe a child has given us data, email support@numford.com and we will remove it. Where a user is below the age of digital consent in their country, we do not show personalised ads to them.

7. Your choices and rights

• Analytics and crash reports: turn each off in Settings, Privacy at any time.
• Reset the choice: clear the game's data in Android settings and the card appears again at next launch.
• Ads: where your region requires a choice, change ad consent in Settings, Privacy, Ad choices, and reset or delete your advertising ID in Android settings, Privacy, Ads.
• Play Games: sign out in the game or in the Play Games app, and delete your Play Games data there.
• Deletion request: email support@numford.com from the device owner's address and include your Firebase installation ID or Play Games player ID if you can. We will delete or ask Google to delete the data tied to it within 30 days. Because analytics data carries no name or email, we may need that ID to find it. Uninstalling the game also stops all collection.
• Depending on where you live, you may also have the right to access, correct, port or object to the use of your data, or to complain to your local data protection authority. Write to us to use these rights.

8. Security

Data sent from the game to Firebase and Google services travels over encrypted connections (HTTPS). Release builds are signed, and the game checks its own save and tuning data before using them. No system is perfectly secure, but we keep what we hold to a minimum.

9. Changes to this policy

If we change what we collect, we will update this page and its effective date, and if the change adds a new purpose the game will ask you again before it applies.
