What we store, and why

What we do not do

• No advertising, and no advertising identifier (IDFA) is requested or used.
• No cross-app or cross-site tracking. No ad networks, no attribution SDKs, no profiling.
• We do not sell data, and we do not give it to anyone for advertising or marketing. The only others who handle it are Google, which runs Firebase and the contact form for us (below), a party that takes over providing the game in a business transfer, and anyone the law requires or allows us to disclose it to.
• No sign-up is needed to play, and we never ask for your phone number, date of birth or address. The name and team name you enter at the start are what the game calls you. They do not need to be your real name, and we suggest you do not use it. An email address reaches us only if you choose to link a save to your Apple account (see below).
• No access to your contacts, location, microphone, or camera.
• No marketing email, no newsletters, no push campaigns. Even if you link your Apple account, we use the address for nothing but replying when you contact us and identifying your save.

Gameplay records, for aggregate analysis

To make the game better, we record how it is played and count it up across all players. For example, we find the stages many people struggle to clear, so we can adjust the difficulty.

We record only events of fixed kinds, as numbers: stages started, cleared and failed and the number of attempts, areas reached, starting and finishing the opening, how long a session lasts (in whole minutes, at most 240), which items are used, completed barters, which product was bought (never the price), which player types are owned, fielded, levelled up and score, which plays are called, match results, quests taken and their outcome, and daily gifts claimed. Each carries a date and time.

Records are filed under the same player ID as your save, so they are not fully anonymous. Nothing you type, such as a team or player name, is ever recorded, and nothing about your device or any advertising identifier is included. We analyse the totals and do not use the records to look into what any one person does.

To stop contributing, turn off Help improve the game under SETTINGS ▸ YOUR DATA. Records not yet sent are discarded and nothing more is recorded. Records already sent stay until their 400 days are up or you use DELETE DATA. Turning it off changes nothing about how the game plays.

If your device's region is set to the EEA (which includes the EU), the UK or Switzerland, we ask on first launch and record nothing until you agree.

Photos on your device

When you set a team crest or a player image, you pick a single picture in the photo picker that iOS shows. The app never sees your whole photo library and does not ask for permission to access your photos. It receives only the picture you pick, keeps it as a square image cropped to 512 by 512 pixels, and does not keep the original file. The image is part of your progress and is backed up to our servers automatically (see Our servers, and where data is stored). It is used inside the game only. The app never writes to your photo library.

Purchases

Purchases are handled entirely by the App Store (Apple). Your card, your Apple account and your billing details are nothing to do with us. What you buy is recorded in your save, and if you contribute gameplay records, which product was bought is recorded too, as a number and never the price. No receipt is sent to our servers, and buying something never passes us your email address.

Linking a save (Cross-device save)

By default your save is attached to a random ID and can be restored on that device only. If you delete the app, the ID can be lost with it, and then the save cannot be found and your progress cannot be brought back. The same applies to a new phone or a tablet: by default your progress does not come with you.

To play on another device, link the save to your Apple account in SETTINGS ▸ YOUR DATA ▸ Cross-device save. Linking is optional, but we recommend it. If that Apple account has no save yet, your player ID and save stay as they are. If it already has one, the app asks whether to switch to it (SWITCH SAVE DATA), and the save on that device is then deleted.

When you link, Apple gives us only an identifier for your Apple account and your email address. No name, password or contacts. If you use Apple's Hide My Email, we receive a relay address instead.

You can unlink at any time on the same screen. Your save then stays on the device under its random ID.

Our servers, and where data is stored

Clash Yard has Google Firebase, a service of Google LLC (United States), store and process data on our behalf. This is where each kind of data is stored:

• Saves, profile information (such as the device name) and gameplay records: Japan (Google Cloud region asia-northeast1).
• Team crests and player images: the United States (Google Cloud region us-west1).
• Sign-in information (your player ID; if you link a save, your Apple account identifier and email address; and IP addresses): the United States. Firebase Authentication runs only in US data centres.
• What you send through the contact form (a Google Form): Google's data centres. We cannot choose the country, so we cannot name it.

If you play from outside Japan or the United States, your data is transferred there. Google LLC is certified under the EU-U.S. Data Privacy Framework, including the UK Extension and the Swiss-U.S. framework, and handles the data for us under the Firebase Data Processing and Security Terms. For players in the EEA and the UK, transfers to Japan rely on the adequacy decisions of the European Commission and the UK, and transfers to the United States rely on that framework and on Google's data processing terms, which include the standard contractual clauses.

For players in the EEA, the UK and Switzerland, we store saves and carry them between devices as necessary to provide the game (performance of contract), record gameplay only with your consent, and keep sign-in secure and answer enquiries on the basis of our legitimate interests. You can withdraw consent at any time on the settings screen. You have the right to complain to the data protection authority where you live.

What you send through the contact form, and the email address you give, are kept to answer your enquiry and deleted once there is no longer a reason to keep them. For how Google handles data, see Firebase's privacy information.

How long we keep data, and deleting it

Your progress is saved automatically as you play, on the device and on our servers, and is kept until you delete it.

To delete it, use SETTINGS ▸ YOUR DATA ▸ Initialize game play ▸ DELETE DATA and confirm twice. Done while you are online, this deletes the data on your device and, on our servers, your save, images, gameplay records, profile information and sign-in record. Done offline, it deletes only the data on your device, and the data on our servers stays. Please delete while you are online.

Deleted data can remain in backups kept for recovery from failures for up to 98 days, and is then erased automatically.

If you delete the app without linking and start again under a new ID, or switch to another save with SWITCH SAVE DATA, the data under the earlier ID stays on our servers and cannot be deleted from the app. To have it deleted, send that player ID and team name through the contact form.

Gameplay records kept for analysis are deleted automatically once 400 days have passed since they were recorded (deletion can take a few days). If you stop contributing, records already sent stay until then or until you use DELETE DATA.

How it is protected

Data is encrypted in transit and at rest. Access is restricted to the people who need it to run the service, and those accounts require two-factor authentication.

Children

Clash Yard is suitable for all ages. We never ask for a date of birth, phone number or address, and there is no advertising or behavioural profiling. The name entered at the start is a name for the game and does not need to be a real name. When a child plays, please do not enter their real name, and set any photo of a real person as a player image together with a parent or guardian. Linking the save of a child under 13 to an Apple account, which shares an email address with us, should be done by a parent or guardian. Gameplay records (numbers only) are used solely to improve the game, whatever the player's age. If we learn we have collected a child's personal information without a parent's consent, we will delete it. Parents and guardians can ask through the contact form to see or delete their child's data.

Your rights over your data, and how to use them

You can ask us to tell you how we use the data we hold about you, to disclose it (including records of any provision to third parties), to correct, add to or delete it, to stop using or erase it, and to stop providing it to third parties. Depending on where you live, for example under the GDPR in the EU and the UK or under California law, you may also have the right to receive your data in a portable form and to object to how it is used.

Much of this can be done in the app. To delete your save and the data on our servers, use SETTINGS ▸ YOUR DATA ▸ Initialize game play. To stop contributing gameplay records, turn off Help improve the game on the same screen.

For anything else, use the contact form. To confirm the request is yours we need both the player ID shown under SETTINGS ▸ SUPPORT and your team name. If you cannot give both, we may be unable to confirm who you are, and so unable to act on the request. Keep a note of the two somewhere others cannot see.

We answer requests within the time the law sets, free of charge.

Changes to this policy

We may revise this policy. When the way we handle data changes, this page is updated before the version that changes it ships, and the date at the top changes with it. The current version always lives here. If a change is significant, we will also post it on our X account and in the app's update notes. If we begin anything that needs your consent, we will ask you for it in the game.
