Privacy Policy — Restaurant Rush

Last updated: November 5, 2026 · Türkçe (KVKK Aydınlatma Metni)

This policy explains how Restaurant Rush: Cook & Serve (“Restaurant Rush”, the “Game”) for iOS and Android, and its website restaurantrush.birkinapps.com, handle your information. The Game is published by Süleyman Gökhan Birkin, an independent developer operating as Birkin Apps in Istanbul, Türkiye (“we”, “us”), who is the data controller. Questions: support@birkinapps.com.

Summary

1. Information we collect

1.1 Player ID and optional account

1.2 Game progress and player profile

1.3 Leaderboards (public)

All leaderboards use your nickname as your display name, or your restaurant name if you have not set a nickname. Please do not use your real name or other personal information as a nickname or restaurant name.

Leaderboard entries are visible to other players in the Game, and the weekly and monthly Endless boards also appear on our public web leaderboard at restaurantrush.birkinapps.com/leaderboard. Deleting your account removes your entries from all of these boards (see section 7).

1.4 Push notifications

If you allow notifications, Firebase Cloud Messaging gives your device a token, which we store in your profile to send reminders and news about events. You can turn notifications off in your device settings at any time; the Game works the same without them.

1.5 In-app purchases

Payments are processed by Apple (App Store) or Google (Google Play) through their own in-app purchase systems (StoreKit and Google Play Billing). When you buy or restore something, the store tells the Game which product it is and gives it a transaction ID and receipt. On Android, the Game sends the purchase token to our server, which checks it with Google Play and records the purchase before it delivers anything. On iPhone and iPad, the Game checks the purchase on your device and delivers the item; the Season Pass is the exception, as our server checks its transaction with Apple’s App Store Server API before granting it (see 1.17). Apple also tells our server about refunds and revocations of App Store purchases, which we match to you through an account token the Game attaches to each purchase and that is derived from your Player ID. The Game keeps a list of already-delivered transactions on your device so that nothing is delivered twice. Your save records which products you own, where your ad-free purchase came from and how many Supporter Packs you have bought (the Supporter Pack can be bought more than once); your player profile shows whether you own a purchase that removes ads; and analytics records each purchase with the product, price and currency (see 1.7). We never receive your card number, billing address or store account details. For sales reporting we keep a purchase record (product, price and date) for each purchase, and it is anonymised, with your Player ID removed, when you delete your account.

1.6 Advertising

The Game shows ads through Google AdMob: rewarded ads that you choose to watch for a bonus, and occasional full-screen ads between shifts. AdMob collects your advertising identifier (on iPhone the IDFA only if you allow tracking in Apple’s App Tracking Transparency prompt; on Android the Android advertising ID), your IP address and the approximate location (country or city) derived from it, device and app information, and how you interact with ads. Where the law requires it (for example in the EEA, the UK and Switzerland), Google’s consent form asks for your choice first; you can change it later with Privacy Options in the Game’s Settings. If you do not consent, you may still see non-personalised or limited ads. A purchase that removes ads turns them off.

1.7 Analytics, crash reports and game configuration

1.8 Actions you take on your device

If you share a score, your device’s share sheet sends the text to the app you choose. Ratings and reviews are handled by Apple or Google; we only see reviews that are published on the store.

1.9 Our website

When you open a page of restaurantrush.birkinapps.com (other than these legal pages), a small script records one visit per browser session. It sends the page address, the referring page, your browser language and screen size. Our server adds your browser’s user-agent and uses your IP address to look up your approximate location (country, region, city) and internet provider through ipapi.co. We store a shortened one-way hash of your IP address, not the address itself. We use these records only to count visits and see where visitors come from. The script does not set cookies; it keeps a single flag in your browser’s session storage so that a visit is counted only once.

1.10 Burger Career

The full Burger Career is unlocked once with Coin, the Game’s premium currency. When you confirm, our server reads the Coin balance in your cloud save to check that you can pay, then writes these records under your Player ID:

The Game also keeps on your device a copy of which rights you own, so the Career opens offline. Your Career progress itself (days, cards, staff and Career settings) is stored only on your device. It is not uploaded or backed up, so deleting the Game removes it.

A guest can unlock the Career after a warning that it stays with that guest ID and can be lost with the Game. If you later sign in to an account you already had, the right and the charge record are moved to that account before the guest data is deleted (see section 7).

1.11 Voices and optional voice downloads

The spoken voices of the Burger Career’s story characters are generated with an AI text-to-speech model. They are not recordings of real people, and no player data is used to make them. A part of them (English and Turkish, the first days) is inside the Game. The rest are optional voice packs.

1.12 Refund requests to Apple

If you ask Apple for a refund of a purchase in the Game, Apple may ask us for information about that purchase to help it decide. We answer only if you agreed: the Game asks you once, after a purchase on iPhone or iPad, and you can change your answer at any time in Settings (“Share purchase use with Apple”). If you agreed, our server tells Apple, for that purchase only: that it was delivered; how much of the Coins it gave you have been spent, measured from your cloud save (if this cannot be measured, we send nothing about it); that the Game can be played without paying; and, if you have spent at least half of those Coins, that we would prefer the refund not to be granted. Apple makes the decision. We keep your answer, with its date and the app version, and a record of what we sent. If you did not agree, or have withdrawn your consent, we send Apple nothing.

1.13 Write to us (support chat)

The Game has a chat called “Write to us”, where you can send the team an idea, a bug report or any other message and read its answers. It is optional, and nothing is sent until you press Send. When you send a message, the Game sends to our server (a Firebase Cloud Function that writes to Cloud Firestore) the text you wrote, the topic you picked (Idea, Bug or Other), the time, and a short device note: the Game’s version, whether the device is iOS or Android, the operating-system version, the Game’s language and whether Accessible play is turned on. This is stored under your Player ID, as one conversation per player together with the team’s answers; only you and our authorised administrators can read it. We use it to read and answer you, to fix what you report and to limit abuse (a daily cap on messages), and for nothing else: it is not used for ads or analytics. When the team needs it, the text of your messages and of the team’s answers is translated between your language and ours by Claude, an AI model made by Anthropic: only the message text is sent, never your Player ID or the device note, and the translation is kept with the message. When a new message arrives we also email it, with the device note and your Player ID, to our own support mailbox (through Gmail). If you allow notifications, our answer also reaches you as a push notification that shows the start of the reply (see 1.4). Please do not write passwords, payment details or other sensitive information in the chat. The conversation is kept until you delete your account or ask us to delete it (see section 7); the email copy is kept as support email (see section 6).

1.14 Community

The Game has a Community page with the team's videos and news and creators' content about the Game. Opening an item takes you to YouTube or your browser, outside the Game, where that site's own privacy policy applies; the Game itself does not contact YouTube and no reward is given for opening, watching, liking or subscribing. To count how much each item is seen and opened, the Game tells our server when you open the page, when an item appears on your screen and when you open one. We keep only daily totals per item, with no Player ID in them; to count each player once a day we also keep, under your Player ID, the list of items counted today, which is replaced the next day and deleted when you delete your account.

1.15 Teams

Teams are for signed-in players: a guest cannot found or join one. Our server (Firebase Cloud Functions writing to Cloud Firestore) stores the following, with your Player ID where it says so.

1.16 Team chat

Each team has a chat. Only the team’s members and our authorised administrators can read it; administrators read it for moderation (reports, held-back messages and safety checks) in our admin panel, and each time one opens a team’s chat it is recorded with who opened it and when. There are no private messages, images or voice. A member can send a typed message (up to 280 characters) or one of a fixed set of quick messages, and the chat also shows a card when a player asks to join and when someone answers.

1.17 Season Pass

The Season Pass gives rewards for season XP. It stores the following on our server:

1.18 Surveys

From time to time the Game can show a short survey. Answering is optional, and a guest may answer. When you submit, our server stores one record per survey and Player ID: the survey, your answers (the choices you picked, ratings from 1 to 5 and any free text of up to 500 characters), the time, whether you were a guest, and the platform (iOS or Android), the Game’s language and its version. Because it is stored with your Player ID, it is linked to you. You can answer a survey only once. Players’ apps cannot read the answers; only our authorised administrators can, in an admin panel that counts the answers per question and lists each response with the player who sent it (their nickname in the Game and their Player ID), its platform and language. Please do not write personal information in a free-text answer.

When our team needs it, Claude (Anthropic) translates into Turkish the free-text answers of players whose Game language is not Turkish. What is sent is only the text of the answers, each under a number of its place in the batch (“a0”, “a1” and so on), and our instructions; no Player ID, record reference, choices, ratings or platform is sent. The translation is stored with your record. We keep survey answers until you delete your account; we have no automatic deletion date for them.

2. What we do not collect

We do not collect precise (GPS) location, contacts, photos or videos, microphone or camera input, health data, payment-card or bank details, or your browsing and search history outside the Game.

3. Why we use information and our legal bases

4. Who we share information with

We share information only with the service providers listed above. They may use it only to provide their services to us, or as described in their own privacy policies linked above, and they provide the same or equal protection of your information as described in this policy and as required by the App Store and Google Play rules.

We do not sell personal information for money. Under some US state laws, letting Google use your advertising ID for personalised ads can count as “sharing” or “targeted advertising”. You can opt out by declining tracking on iPhone, by deleting or resetting your advertising ID on Android (Settings → Google → Ads, or Settings → Privacy → Ads), or through Privacy Options in the Game where available.

5. International transfers

Google, Apple and ipapi.co process data in the United States and other countries. When data leaves the EEA, the UK or Türkiye, these providers rely on Standard Contractual Clauses or other safeguards required by law (including KVKK Art. 9).

6. How long we keep information

7. Deleting your data

In the Game (signed-in players)

  1. Open Settings from the main menu.
  2. Scroll to Danger Zone and tap Delete Account.
  3. Confirm. You may be asked to sign in again with Apple, Google or your password.

This immediately and permanently deletes your sign-in account, cloud save, player profile (including email, push token and accessible-play pace setting), all of your leaderboard entries (the weekly and monthly Endless boards, the Relaxed boards and the Chef-level board), your league membership, your session records, your Write to us conversation, your Burger Career right and Coin charge record, your team membership (you leave your team, as if you had pressed Leave), your join requests and chest claims, your team chat limits, authored-message list and block list, your Season Pass progress, your survey answers, pending grants, and related anti-abuse records. Your team chat messages stay in the chat for the rest of their 30 days but show as “Deleted player”, with their text and translations emptied and your Player ID removed; the copies of them on reports are emptied the same way. In the sale record of the Burger Career and in the league payout records, your Player ID and name are removed instead; the rest stays (see section 6). The Game then continues with a new guest profile on that device.

If you played as a guest on a device and then signed in to an account you had created earlier, the Game asks our server, right after you sign in, to delete the guest’s player profile, cloud save, session records, leaderboard entries and guest sign-in. If the guest unlocked the Burger Career, it is moved to your account first. This runs in the background and is tried again a few times. If it cannot finish (for example, you have no connection), the guest’s data stays under the separate guest ID until you ask us to delete it: email support@birkinapps.com. If you link Apple or Google to the guest account itself, nothing is moved: the account keeps the same Player ID.

By email (guests, or if you no longer have the Game)

Email support@birkinapps.com with the subject “Delete my Restaurant Rush data”. Include the ID shown in Settings and, if you signed in, the email address of your account. We delete the data within 30 days and confirm by email. Step-by-step instructions are also at restaurantrush.birkinapps.com/delete-account.html.

What deletion does not cover

8. Your choices and rights

9. Children

Restaurant Rush is made for a general audience and is not directed to children under 13 (or the minimum age of digital consent in your country). We do not knowingly collect personal information from children. If you believe a child has given us personal information, contact us and we will delete it.

10. Security

Data is encrypted in transit (HTTPS/TLS). Cloud saves and profiles are protected by Firestore security rules so that only you — and our authorised administrators, for support — can read them, and scores are validated on our servers. No system is perfectly secure, but we work to protect your data.

11. Changes to this policy

We will post any update on this page and change the “Last updated” date. If a change is significant, we will also tell you in the Game or in the store listing.
