Privacy Policy
This policy covers the games published by YYUKA Studio and the website at yyukastudio.com. It is written to be read, not to be survived.
The short version
The game gives you an account automatically so your progress survives a new phone and the leaderboard has someone to rank. You never sign up, and we never ask for your name, your e-mail or your phone number. You can delete the account from inside the game at any time.
What the game keeps on your device
The following is saved in the game's own local storage, on your phone:
- Your settings: interface language, selected map, sound and music volume.
- Your energy, pass and joker counts.
- The map packs you have downloaded.
- A copy of your recent games, so the game works offline and syncs when the connection comes back.
- Your answers to the consent questions described below.
Uninstalling the game removes all of it, map packs included.
Permissions the app asks for
| Permission | Why the app asks for it |
|---|---|
| Network access | The game talks to our server to keep your progress, run leaderboards and lobbies, and download map packs. It still plays offline: finished games queue up on the device and sync when the connection comes back. |
| App storage | The game writes your progress and settings into its own private storage area. This needs no prompt on modern Android or iOS, and it gives the game no access to your photos, documents or anything else on the device. |
| Advertising identifier | From version 1.7. Used by the advertising network to cap how often you see the same ad and to measure it. On iOS this appears as an App Tracking Transparency prompt, and on Android you can reset or delete the identifier in system settings. Declining is fine — you still get to play, and you still get ads, just untargeted ones. |
| In-app billing | From version 1.7, on Android. Lets the app talk to the App Store or Google Play to complete a purchase. No payment detail ever reaches us. |
| Network state | So the game can tell whether you are online before it tries to join a lobby. |
| Device language and region | Read to pick a starting map and interface language that make sense for you, and stored with your account so it does not have to be asked again. This is your device's locale setting, not your position: the game cannot read GPS and never asks the operating system for location. Where the law requires consent for it — the EEA and the UK, Türkiye, China, South Korea, Brazil, India, Russia, Canada, South Africa, the United States, Australia and New Zealand — the game asks before reading it, and works if you decline. |
| Saving a picture to Photos | Asked for only when you tap Save your map at the end of a game, and only on iOS. It is the add-only permission: the game can put that one image into your photo library and nothing else. It cannot open, read or list your photos, and declining costs you nothing but that one save. Android needs no permission for this. |
What we store on our server
When you first open the game it creates an account for you automatically. You do not sign up and you are not asked for your name or e-mail. The following is stored on our server, api.yyukastudio.com:
- Nickname — generated randomly by the server. You can change it.
- Device ID — a random number generated on your device. It is not an advertising identifier and is not derived from your hardware.
- Game data — level, experience, scores, which maps you played and summaries of finished games.
- Friends list — the IDs of players you added.
- Nickname history — the names you have used, so an abandoned name can be freed for someone else and a banned player cannot simply rename their way out.
- Device region and platform — the country code from your device's locale, and whether you are on iOS or Android.
- Your consent answers — which consent you were asked for, under which law, what you answered and when. We are required to be able to show this.
- Reports and blocks you make — see below.
- Messages you send us — suggestions and complaints you write in the app, with the language, map and app version you had open when you wrote them.
- Purchase records — if you buy Premium: the store's transaction ID, the product, when it was bought and its status. See Purchases.
- Linked game profiles — if you link Game Center or Google Play Games: the player ID that service assigns you. See Linking a game profile.
This is used only to run the leaderboard, keep your progress when you change device, maintain your friends list, moderate what players write and detect cheating. It is not used for marketing, not sold, and not shared with third parties.
Our data lives on Cloudflare infrastructure, at api.yyukastudio.com, which holds the data above, and cdn.yyukastudio.com, which serves the map packs. Both are ours. In iOS 1.0 and Android 1.6 those are the only places the game connects to. From version 1.7 it also uses Google's advertising service, Apple's and Google's stores for purchases and Game Center or Google Play Games if you link a profile — each described in its own section below. No version has an analytics service or an AI service.
We do not collect your name, e-mail address, phone number, location, contacts or photos. Our server never receives your advertising identifier. From version 1.7 it is read on your device by Google's advertising SDK, as described under Advertising.
Your nickname is visible to other players on leaderboards and in lobbies. Do not put anything in it that you would not want strangers to read.
Reporting and blocking
Nicknames and lobby names are the only text one player can show another. There is no chat, no image sharing and no profile text. Nicknames are checked against a filter on our server before they are accepted.
Anywhere another player's nickname appears — the leaderboard, the friends search, the end-of-game standings — a More button opens Report and Block.
- Reporting sends us who reported whom and the reason given. We read reports and act on them within 24 hours, and we can ban an account from our moderation tool.
- Blocking is one-way and private. The blocked player disappears from your leaderboard and your search results; they are not told, and nothing about them changes on their side.
We keep reports and blocks after they are dealt with, because a pattern across several reports is usually the only way to tell a bad actor from a bad day. Deleting your account removes every report and block you made or received, in both directions.
Deleting your account
In the app: Profile → Delete My Account. This removes your nickname, level, scores, leaderboard entries and friends list from our server immediately, and cannot be undone.
If you want to request deletion without installing the app, e-mail contact@yyukastudio.com with your nickname (for example Poyraz#4349). Requests are processed within 30 days.
Downloaded map packs stay on your device after deletion — they are not personal data, and re-downloading them would cost you the bandwidth again. Uninstalling the app removes them.
Advertising
From version 1.7, the free game shows ads served by Google AdMob. Versions 1.0 on iOS and 1.6 on Android contain no ads and no advertising code.
Ads come in two kinds: rewarded ads you choose to watch, for extra energy, passes or jokers; and one full-screen ad when you leave a finished game, which is skipped if you already watched an ad during that game. Premium removes the full-screen ad. Rewarded ads stay available, for when you want the reward.
To show and measure ads, Google's Mobile Ads SDK in the app processes your device's advertising identifier (the IDFA on iPhone, the advertising ID on Android), your IP address and the coarse location derived from it, your device model and operating system, which ads you saw or tapped, and diagnostic data about how ads load. Google processes this as an independent controller under its own policy — see how Google uses information from apps that use its services. None of it reaches our server.
In the EEA, the UK and Switzerland the game shows Google's consent form — a certified consent management platform — before any ad is requested, as the GDPR and the ePrivacy Directive require. You can decline, and you can change your answer at any time under Settings → Ad Privacy Options.
On iPhone the game then asks once for App Tracking Transparency permission. If you choose Ask App Not to Track, your advertising identifier is not shared and ads are not personalised with your activity in other apps. On Android you can reset or delete the advertising ID in your system settings.
Declining any of this does not stop the game. You still see ads; they are limited or non-personalised. And because the game is rated 13+, ads are restricted to content rated T (Teen) or below.
The coarse location comes from the IP address alone. The game does not request the location permission and cannot read your GPS position.
Purchases
From version 1.7 the game sells one thing: Premium, a one-time purchase that gives unlimited energy, removes the full-screen ad and allows unlimited nickname changes (one a day). It is sold through the App Store and Google Play wherever your version of the game offers it. Versions 1.0 on iOS and 1.6 on Android sell nothing.
Payment is handled entirely by Apple or Google. We never see your card details, billing address or any other payment information.
What we keep is the store's transaction ID, the product, when it was bought, whether it was a real or a test purchase, and its status — enough to unlock Premium on your account, restore it, and withdraw it if the purchase is refunded. Premium belongs to the store account you bought it with.
Refunds are handled by the store you bought from, under its own policy. Your statutory rights as a consumer in the EU, the UK and Türkiye are set out in our terms of use.
Linking a game profile
There is no e-mail and no password in Piri. From version 1.7 you can choose to link your account to your Game Center profile on iPhone, or to your Google Play Games profile on Android where available, so your progress comes back on a new phone or after reinstalling. The button is in the profile box; nothing is linked unless you press it.
Linking stores one thing next to your account: the player ID that Apple or Google assigns to your game profile, which our server checks against a signed proof from the platform. We do not ask those services for your Apple ID, your Google e-mail address or your contacts.
Where local law requires it, the game asks for consent before linking. You can unlink at any time from the same box, and deleting your account removes every link.
What the game does not do
No version of the game contains an analytics or crash-reporting service of ours, or any AI service. We do not build profiles of players and we never sell data. Our server never receives your advertising identifier; any ad personalisation is Google's, and only with the consent described under Advertising.
This website
The site is static and is hosted on Cloudflare Pages. It sets no cookies, runs no analytics, embeds no trackers and loads nothing from any other domain — so there is no consent banner, because there is nothing to consent to. Cloudflare processes request data, including IP addresses, in order to serve and protect the site; that processing is covered by Cloudflare's own privacy terms.
There is one small script on the page, and all it does is run the light/dark theme button. If you use it, your choice is saved in your browser's local storage under the name theme so the site remembers it on your next visit. That value stays in your browser, is never sent to us, and clearing your site data removes it. It is strictly necessary to provide the preference you asked for, so it needs no consent banner.
If you email us, we keep the email so that we can answer it and refer back to it. We do not add you to a mailing list.
Age 13 and over
Our game is intended for players aged 13 and over, and it is declared that way in both stores. We do not knowingly collect personal data from children under that age, we do not direct the game at children, and it is not enrolled in Google Play's Families programme.
If you believe a child has provided us with personal data, write to contact@yyukastudio.com and we will delete it.
Why we are allowed to process what we process
Under the GDPR every use of personal data needs a legal basis. Ours are these:
| What | Legal basis |
|---|---|
| Answering an email you sent us | Our legitimate interest in replying to people who write to us (GDPR Art. 6(1)(f)) |
| Serving this website securely | Our legitimate interest in keeping the site available and protected from abuse (Art. 6(1)(f)) |
| Creating your account, saving your progress and running leaderboards, lobbies and the friends list | Performance of the contract you enter by playing the game (Art. 6(1)(b)) |
| Detecting cheating and keeping the leaderboard honest | Our legitimate interest in a leaderboard that means something (Art. 6(1)(f)) |
| Reading your device's language and region to pick a starting map | Your consent where local law requires it, otherwise our legitimate interest in opening on a map you recognise (Art. 6(1)(a) / (f)) |
| Validating and restoring a purchase | Performance of the contract (Art. 6(1)(b)), and our legal obligation to keep sales records (Art. 6(1)(c)) |
| Personalised advertising, and reading or writing anything on your device for advertising | Your consent (Art. 6(1)(a) and the ePrivacy Directive), which you can withdraw at any time |
| Showing limited or non-personalised ads | Our legitimate interest in keeping the game free to play (Art. 6(1)(f)); anything stored on or read from your device for advertising still follows your answer in the consent form |
| Linking a Game Center or Google Play Games profile | Performance of the contract, at your request (Art. 6(1)(b)), with your consent where local law requires it |
Data that never leaves your device is not processed by us at all — we are not the controller for it, because we never receive it.
How long we keep things
- Everything the game stores on your device stays there until you delete the game or clear its data. We cannot reach it and cannot delete it for you.
- Emails you send us are kept while we are dealing with them and for as long as we might reasonably need to refer back, then deleted.
- Your account and everything attached to it — nickname, device ID, level, scores, leaderboard entries, friends list, reports and blocks — are kept until you delete the account. Deleting it from the app removes them immediately.
- Suggestions and complaints you send from inside the app are kept while we act on them, and go with the account when you delete it.
- Consent records outlive the account, with your player ID replaced by a deletion marker, because being able to show that consent was asked and answered is itself a legal requirement.
- Purchase records are kept for as long as tax and accounting law requires sales records to be kept, with your player ID removed if you delete your account.
- Links to Game Center or Google Play Games are kept until you unlink them or delete your account.
Where your data goes
We are established in Türkiye, outside the European Economic Area. Where personal data of people in the EEA or the UK reaches us or our providers, the transfer is made under the European Commission's Standard Contractual Clauses or an equivalent safeguard. You can ask us which one applies to a given provider. When Google serves ads it transfers data under its own safeguards, described in its privacy policy.
Your rights
Under the GDPR, the UK GDPR and Türkiye's KVKK you have the right to:
- ask what personal data we hold about you and get a copy of it;
- have inaccurate data corrected;
- have your data erased;
- restrict or object to how we use it, including objecting to direct marketing at any time;
- receive the data you gave us in a portable format;
- withdraw any consent you gave, without that affecting what was lawful before you withdrew it;
- not be subject to a decision based solely on automated processing that significantly affects you — we make none.
Two of these are built into the game rather than left to e-mail: the app can produce a copy of everything your account holds, and it can delete the account outright from Profile. For anything else, write to contact@yyukastudio.com — requests get a real answer, free of charge, within one month.
If you are not satisfied with our answer you can complain to a supervisory authority: in the EEA, the data protection authority of the country you live in; in the UK, the Information Commissioner's Office; in Türkiye, the Personal Data Protection Authority (KVKK).
Changes to this policy
When the policy changes, the date below changes with it and the new version replaces this one on this page. Material changes are also noted in the game's release notes.
