Privacy Policy

Last updated: 12 November 2026

1. Who we are

This policy covers the Billionvale mobile game (“the Game”). The controller of your personal data is Billionvale. For questions and requests: lunaydestek@gmail.com

2. What data we use and why

2.1 Game data that stays on your phone

Your money, businesses, achievements and settings are stored on your phone. With cloud backup on, a copy of this game data is also sent to our server (see 2.3a). A save code is text you can copy to move your progress to another device. It is created on your phone, and we never see it unless you send it to us.

2.2 Usage statistics and crash reports

We use Google’s Firebase services:

• Google Analytics for Firebase: a random app instance ID, a device identifier (IDFV on iOS, Android ID on Android), device model, operating system and app version, language, approximate country and region derived from your IP address, and when sessions start and how long they last. In addition, in-game events: the actions you take in the game (for example finishing the tutorial, opening a business or mechanic, prestiging, trading, building, missions, auctions, orders and similar game actions, collecting achievements and rewards, watching a rewarded ad, making a purchase, sharing, using a friend code, returning to the game after a while, which game worlds and the shop you open) and these user properties: the wealth tier you reached, whether you have made a purchase, the week you installed the game, the game's language and how many worlds you have visited. Your session count and the time since your last visit are sent only as coarse ranges (e.g. sessions 6–10, 4–12 hours away); the number of whole days since you installed the Game is sent as a number. These events carry game values only (such as a rank, a day or the option chosen), never personal information or free text.
• Firebase Crashlytics: when the Game crashes or hits an error, the error trace, device model, operating system and app version, memory and disk state, and a random installation ID.

Why: to see which parts of the Game are too hard or too slow, to tune its balance, and to fix bugs. Analytics does not collect your advertising ID for this, and none of this data is used for advertising.

To turn it off: in the Game, Settings → Gizlilik ve destek → Kullanım istatistikleri.

2.3 Friend codes

For the friend code feature, your phone is given a random, anonymous ID (a Firebase Authentication anonymous session). Our server (Cloud Firestore) stores only:

• your friend code and the anonymous ID that owns it (one code per ID),
• the code you joined with,
• the anonymous IDs of players who joined with a code,
• when these records were created.

Your name, email and contacts are never used. Why: to reward both you and the friend who enters your code, and to prevent abuse of the feature. These records are stored on servers in the European Union. Running these services also technically involves your IP address and device information; for example, Firebase uses IP addresses to limit abuse.

2.3a Cloud backup

The Game backs up your progress to our server (Cloud Firestore, EU) under the same anonymous ID, so you can take your game to a new phone. The backup holds only the game’s own progress: your money, businesses, the worlds you opened and your achievements. It leaves out your purchases and ad counters (purchases come back from your store account), your friend code and this phone’s own settings, such as sound, language and the statistics switch; it keeps only how many Time Warps were already delivered, so they are not delivered twice. No name, email or contacts. The backup gets a backup code (BV-…). Anyone who knows the code can read the backup; only the phone that made it can change or delete it. Do not share your code.

2.3b Leaderboard (Game Center, Google Play Games)

If you open the leaderboard, you sign in to Apple Game Center or Google Play Games and your wealth score (a single number derived from your total earnings) is sent there. The name shown there comes from your Apple or Google account; we do not store it. Apple and Google process this data under their own privacy policies.

2.3c Weekly League

When the Weekly League opens for you, the Game places you each week in a group of up to 30 players under the same anonymous ID. Our server (Cloud Firestore, EU) stores your anonymous ID, the week and group you play in, a generated name (random game words picked by the Game, never text you type), your weekly league score and when it was last updated. If you leave a week (for example with “delete my server data”), a record that you gave up your seat is kept so the seat is not taken again that week. Other players can see the group’s table: each member’s generated name, score and anonymous ID. No name, email or contacts. Why: to run the league, rank the group and prevent cheating.

2.3d Game settings, app integrity and time check

These run whenever the Game can reach its server, including when usage statistics are off:

• Firebase Remote Config and Firebase Installations: the Game downloads its current balance settings. For this, a random Firebase installation ID, the app and its version, the operating system, your device’s language, country and time zone settings and your IP address are sent to Google. Why: to tune the game’s balance without an app update.
• Firebase App Check (with Apple App Attest on iOS and Google Play Integrity on Android): Apple or Google confirms to our server that requests come from the genuine Game on a genuine device. This involves an attestation of your device and app and your IP address. Why: security and abuse prevention.
• Time check: when the Game opens or comes back to the screen, it asks our website (Firebase Hosting, richgame-idle.web.app) for the current time. Only a standard web request is made, which carries your IP address and standard request headers; nothing about you or your game is sent. Why: so changing the phone’s clock cannot be used to cheat daily rewards.

2.4 Ads (Google AdMob)

The Game contains only rewarded video ads. An ad is shown only when you choose to watch one for a reward. Ads are served by Google AdMob. To show ads, measure them and prevent fraud, Google may process your advertising ID (IDFA on iOS, only with your permission; the advertising ID on Android), IP address, device and app information, and your interactions with ads.

• Players in the EU, the UK and Switzerland are shown Google’s consent form.
• On iOS, we ask for Apple’s App Tracking Transparency permission before personalised ads.

If you decline, ads are shown without personalisation. You can change your choice at any time:

• In the Game: Settings → Reklam gizlilik ayarları (shown when consent is required in your region)
• On iOS: Settings → Privacy & Security → Tracking
• On Android: your phone’s ad settings

How Google uses data: policies.google.com/technologies/partner-sites

2.5 Purchases

Payments are processed by Apple (App Store) or Google (Google Play). We never see your card details. We use RevenueCat to verify and restore purchases. RevenueCat processes a random user ID, your purchase records (product, price, currency, date, transaction ID), your store country, device and app information, and your IP address.

2.6 Notifications

Reminder notifications are scheduled on your phone. No data is sent to our servers for them. Allowing notifications is optional. At most two reminders are sent per day.

2.7 Sharing

When you share your wealth card, the image and text go through your phone’s share menu to the app you choose. We do not receive a copy. The rules of the app you choose apply.

2.8 Support emails

If you email us, we use your email address and message only to reply and resolve your request.

3. Legal bases

Under Article 5 of Turkey’s Personal Data Protection Law No. 6698 (KVKK) and, where it applies to you, Article 6 of the EU General Data Protection Regulation (GDPR), we rely on:

• Performance of a contract: providing the Game, the items you buy, friend code rewards, cloud backup and the Weekly League.
• Legitimate interests: usage statistics, crash reports, game balance settings, security and abuse prevention (including App Check and the time check). You can turn statistics and crash reports off at any time.
• Consent: personalised ads, tracking on iOS, and notifications. You can withdraw consent at any time.
• Legal obligation: keeping purchase records as tax and accounting law requires.

4. Who we share data with

We do not sell your data. We share it only with the service providers needed to run the Game, who process it on our behalf:

Otherwise, we share data with authorities only when the law requires it.

5. International transfers

Our providers’ servers are outside Turkey, mainly in the United States and the European Union, so your data is transferred abroad. Friend code, cloud backup and Weekly League records are stored in the EU. Our providers offer safeguards for these transfers in their data processing terms; Standard Contractual Clauses are one example.

6. How long we keep data

• Game data on your phone: until you delete the app.
• Usage statistics: event-level data for at most 14 months. After that, only aggregated reports without identifiers remain.
• Crash reports: 90 days.
• Friend code records: while the feature exists, or until you delete them in the Game or ask us to.
• Cloud backup: each backup replaces the last; kept until you delete it in the Game or ask us to. A reinstall usually gives your phone a new anonymous ID, which can no longer delete the old backup from the Game; email us with its backup code and we will delete it. On an iPhone the ID can survive a reinstall: the Game then finds your backup and asks whether to restore it, and never replaces it with a game that is less far along unless you choose to.
• Weekly League: your group entries, including past weeks, are kept until you delete them in the Game or ask us to. A record that you gave up a seat is deleted automatically about two weeks after that week ends.
• Purchase records: as long as the law requires.
• Support emails: up to 2 years after your request is resolved.

7. Your rights and how to use them

Under Article 11 of the KVKK and, where it applies to you, the GDPR, you have the right to:

• know whether your data is processed and ask for information about it,
• ask for your data to be corrected, deleted or given to you,
• object to processing and withdraw your consent,
• ask for compensation for any damage.

If you have a complaint, you can contact Turkey’s Personal Data Protection Authority or, in the EU, the data protection authority of your country.

Send your request to lunaydestek@gmail.com. The Game has no accounts, so we can find your records on the server only by your friend code. You can see it in the Game under Settings → Arkadaşlar; please include it in your email. We reply within 30 days at the latest.

You can also delete your server records yourself in the Game: Settings → Gizlilik ve destek → Sunucudaki verilerimi sil (delete my server data). This immediately deletes your cloud backup, your Weekly League entry, your friend code, the records of who joined with it, the code you joined with and your anonymous account, and resets your analytics ID. It also turns the Game’s automatic cloud backup off, so nothing is sent again until you turn it back on. A backup made in the last minute can be deleted once that minute is over; if deleting fails, try again a minute later. To have collected statistics and crash reports deleted as well, email us.

To delete the game data on your phone, just delete the app. You can turn usage statistics and crash reports off in Settings.

8. Children

The Game is not directed at children under 13, and we do not knowingly collect personal data from them. If you believe a child has given us data, write to us and we will delete it.

9. Security

Data is encrypted in transit (HTTPS/TLS). Access to friend code records on the server is limited by security rules. Only a code’s owner can see who joined with it. Friend code records cannot be changed. A cloud backup can be updated (at most once a minute; the Game itself waits at least two minutes between backups) and deleted only by the phone that created it. A Weekly League score can be changed only by the player it belongs to, and only within limits the server checks. Only the player who created a record can delete it. We collect only the data we actually need.

10. Changes

We may update this policy. The current version is always at this address. The date of the last change is shown at the top.
