本隐私政策说明手机游戏《地煞大D》如何处理你的信息。开发者：DAYDREAMER GROUP SDN. BHD.。如有疑问请联系 daydreamerddg@gmail.com。

1. Information We Collect

We only collect data when you choose to create an account, sign in, or play as a guest (the optional cloud-sync feature), or when you make an in-app purchase. In that case we collect:

• Email address & password — used only to create and access your account. Authentication is handled by our backend provider (Supabase); your password is stored in hashed form and is never visible to us.
• Sign in with Apple — if you sign in with your Apple ID, Apple sends us an identity token from which we obtain your email address and a unique account identifier. If you choose Apple's Hide My Email option, we only ever receive Apple's private relay address, not your real one. We never receive your Apple ID password.
• Sign in with Google — if you sign in with your Google account (on Android), Google provides us an ID token from which we obtain your email address, basic public profile information (such as your name and profile picture), and a unique account identifier. We never receive your Google account password.
• Nickname (optional) — if you provide one at registration.
• A unique account identifier — assigned to your account.
• Game progress & activity — such as in-game currency, levels cleared, unlocked content, achievements, and current run state, so your progress can be synced across your devices.
• Purchase records — for each in-app purchase we store the product identifier, the product title, the price and currency, the purchase status, and the in-game items granted, linked to your account. We never receive or store your payment card details — see section 3.
• Technical & connection data — when your device connects to our servers (to sync progress or complete a purchase), our backend automatically records your IP address, an approximate location (country) derived from it, and your device type / platform. We use this for account security, abuse and fraud prevention, and to understand aggregate usage (for example, which regions and platforms are active).

仅当你选择注册、登录或游客登录（可选的云同步功能），或进行应用内购买时才收集：邮箱与密码（仅用于账号，密码经哈希存储，我们无法看到明文）；使用 Apple 登录时，Apple 会向我们提供一个身份令牌，我们据此获得你的邮箱与账号唯一标识——若你选择 Apple 的「隐藏邮件地址」，我们只会拿到 Apple 的转发地址，而非你的真实邮箱，且我们永远不会拿到你的 Apple ID 密码；使用 Google 登录（Android）时，Google 会向我们提供一个身份令牌，我们据此获得你的邮箱、基本公开资料（如姓名、头像）与账号唯一标识，我们永远不会拿到你的 Google 账号密码；昵称（可选）；账号唯一标识；游戏进度与活动（香火、关卡、成就、当前进度等，用于多设备同步）；购买记录（商品标识、名称、价格与币种、交易状态、发放的游戏内物品，与你的账号关联）。我们不会接触或存储你的支付卡信息，详见第 3 节。此外还有技术与连接数据——你的设备连接我们服务器（同步进度或购买）时，后端会自动记录你的 IP 地址、由此推断的大致位置（国家）与设备类型/平台，用于账号安全、防滥用与防欺诈，以及了解整体使用情况（如活跃地区与平台）。

2. How We Use Your Information

We use the information to provide account login, to synchronize your game progress across devices, to deliver and restore the in-app items you have purchased, to operate features such as the public leaderboard, and to keep the service secure and understand aggregate usage (such as active regions, platforms, and player counts). We do not use it for third-party advertising, and we do not sell it.

这些信息用于账号登录、跨设备同步游戏进度、发放与恢复你已购买的应用内物品、运行公开排行榜等功能，以及保障服务安全与了解整体使用情况（如活跃地区、平台与玩家数）。我们不用于第三方广告，也不出售你的数据。

3. Purchases & Payments

The App offers optional in-app purchases (such as in-game currency packs and cosmetic items). All payments are processed by the platform's app store — Apple through the App Store on iOS, or Google through Google Play on Android — using their respective in-app billing systems.

• Your payment method, card number, and billing details are handled entirely by Apple or Google. We never see, receive, or store them.
• We receive only a confirmation that a purchase completed, and we record which product it was (see section 1) so we can grant your items and restore them if you reinstall the App.
• Purchases of non-consumable items can be restored via the Restore Purchases option in the App's store screen.
• Apple's handling of your payment data is governed by the Apple Privacy Policy; Google's by the Google Privacy Policy.

本应用提供可选的应用内购买（如香火礼包、外观道具）。所有付款均由平台应用商店处理——iOS 上为 Apple（App Store 内购），Android 上为 Google（Google Play 结算）：你的支付方式、卡号与账单信息完全由 Apple 或 Google 处理，我们不会看到、接收或存储；我们只收到「购买已完成」的确认，并记录商品信息（见第 1 节）以便发放物品、以及在你重装后恢复购买；非消耗型商品可在商店页的「恢复购买」中恢复。Apple 对你支付数据的处理适用 Apple 隐私政策，Google 适用 Google 隐私政策。

4. Advertising

The App does not contain third-party advertising and includes no advertising SDKs. We do not share your data with advertisers.

本应用不含第三方广告，未集成任何广告 SDK，不会把你的数据分享给广告商。

5. How Your Data Is Stored & Shared

Account and cloud-save data is stored using Supabase, our backend and database provider, acting as a data processor on our behalf. Data is transmitted over encrypted connections (HTTPS). Public leaderboard: if you sign in, your nickname and certain game results (such as levels cleared, ascension, and best endless/daily scores) are shown on an in-game leaderboard that is visible to other players. If you play as a guest or leave your nickname blank, an anonymized name is shown instead of your email or real name. Aside from the leaderboard, we do not sell your personal data or share it with third parties for their own marketing.

账号与云存档数据存储于后端服务商 Supabase（作为我们的数据处理方）。数据通过加密连接（HTTPS）传输。公开排行榜：若你登录，你的昵称与部分游戏战绩（如通关层数、飞升、无尽/每日最佳成绩）会显示在游戏内排行榜上，对其他玩家公开可见；若你以游客身份游玩或未填昵称，则显示匿名代称，而非你的邮箱或真实姓名。除排行榜外，我们不出售你的个人数据，也不为第三方营销目的分享。

6. Data Retention & Deletion

We keep account data for as long as your account exists. You can:

• Sign out at any time from inside the App (your local progress stays on the device).
• Request deletion of your account and all associated cloud data by emailing daydreamerddg@gmail.com from, or stating, your account email address. We will delete your data within 30 days.

数据保留至账号存在期间。你可以随时在 App 内退出登录（本机进度保留）；或发邮件至 daydreamerddg@gmail.com（注明账号邮箱）申请删除账号及全部云端数据，我们将在 30 天内删除。

7. Children's Privacy

The App is not directed to children under 13, and we do not knowingly collect personal information from children under 13.

本应用不面向 13 岁以下儿童，我们不会有意收集 13 岁以下儿童的个人信息。

8. Changes to This Policy

We may update this Privacy Policy from time to time. The "Last updated" date at the top reflects the latest revision.

我们可能不时更新本政策，顶部的「最后更新」日期为最新版本。
