Crash&Snakeskin 隐私政策
生效日期：2026 年 10 月 22 日开发者：Tianmatai Studio联系邮箱：tianmataistudio@gmail.com
简单来说：本游戏不需要注册账号，不收集你的姓名、邮箱、电话、位置、通讯录、照片等个人信息，也没有广告和应用内购买：游戏里的金币和宝石只能通过玩游戏获得，不能用真钱购买。为了改进游戏，它会把匿名的游戏统计数据发送给开发者，用一个随机生成的编号区分不同的手机。
本政策说明手机游戏 Crash&Snakeskin（下称“本游戏”）会收集哪些信息、怎样使用和保存，以及你可以怎样查看或删除这些信息。
1. 我们收集的信息
本游戏联网时会自动发送以下匿名统计数据：
- 匿名编号：第一次打开游戏时随机生成的一串字符，只用来区分不同的安装。它不是根据手机硬件编号、广告 ID 或任何账号生成的，无法用来识别你本人。每次打开游戏还会另外生成一个随机的会话编号。
- 设备信息：手机型号、系统版本、屏幕分辨率、内存大小、游戏语言、游戏版本号、安装渠道。
- 游戏数据：游戏里发生的事件和发生时间，例如开始、放弃和结束一局，起飞、降落和飞行距离，捡到的零件，卖给旅行商人的物品和得到的金币，机库里购买和更换的升级（雷达、座舱、挂载点），获得的成就，查看飞机，打开隐私政策，设置的变更（语言、界面布局），“保存到相册”是否成功，以及打开、切到后台、退出游戏的时间和游玩时长。
我们不收集：姓名、邮箱、电话号码、精确或大致位置、通讯录、照片和文件内容、广告 ID、IMEI 和 Android ID 等设备硬件编号、支付信息。
2. 用途
- 了解大家怎么玩：玩到了哪里、在哪里卡住、哪些功能有人用。
- 调整难度和数值，比如金币收益和升级价格。
- 发现程序错误和性能问题。
- 统计各个安装渠道的玩家人数。
这些数据不用于广告，不做用户画像，也不出售。
3. 发送、存储和安全
- 数据通过加密连接（HTTPS）发送到开发者自己的 Google Apps Script 网页应用，保存在开发者 Google 账号下的私人 Google 表格里，只有开发者能看到。Google 作为托管服务商处理这些数据，详见 Google 隐私权政策。数据可能存放在你所在国家或地区以外的服务器上。
- 没有网络时，事件先存在你手机上本游戏的私有目录里（最多 500 条），联网后再发送。
- 和任何网络连接一样，Google 的服务器接收数据时会看到你的 IP 地址；我们不会把 IP 地址记录到表格里。
4. 共享
我们不出售、不出租这些数据，也不和任何第三方共享，法律要求的情况除外。
5. 保留期限
统计数据最多保留 24 个月，之后删除，或者只留下不带编号的汇总数字。
6. 你的选择和权利
- 游戏设置面板里“隐私政策”右边显示的是你这台手机的匿名编号，点一下就能复制。把它发到 tianmataistudio@gmail.com，我们会在 30 天内删除这个编号对应的全部数据；用同样的方式也可以索取这些数据的副本。
- 卸载本游戏会删掉手机上的匿名编号和还没发出去的数据；重新安装会生成一个和以前无关的新编号。
- 统计数据是游戏运行的一部分，目前没有单独的关闭开关。如果你不同意本政策，请不要使用本游戏。
7. 只保存在你手机上的数据
游戏进度、最远纪录、金币、宝石、图鉴收集、机库升级和各项设置都只保存在你的手机上，不会上传；卸载游戏后会一起删除。“保存到相册”（Android 10 及以上）会把你主动保存的图片存进手机的“图片 / CrashAndSnakeskin”相册，同样不会上传。
8. 权限
本游戏只使用两个普通权限：“网络访问”（用来发送统计数据）和“振动”（撞进风暴云等时刻让手机振动一下）。不申请位置、相机、麦克风、通讯录或存储权限。
9. 儿童
本游戏不面向 13 岁以下的儿童，我们也不会有意收集儿童的个人信息。本游戏收集的数据是匿名的；如果你认为我们收到了儿童的个人信息，请联系我们删除。
10. 政策变更
本政策更新时，我们会修改本页面和上面的生效日期。以后如果加入广告、应用内购买或其他会收集数据的服务，会先更新本政策。
11. 联系我们

Crash&Snakeskin Privacy Policy
Effective date: October 22, 2026Developer: Tianmatai StudioContact: tianmataistudio@gmail.com
In short: the game needs no account and does not collect your name, email, phone number, location, contacts, photos or other personal information. It has no ads and no in-app purchases: coins and gems can only be earned by playing and cannot be bought with real money. To improve the game, it sends anonymous gameplay statistics to the developer, using a randomly generated ID to tell devices apart.
This policy explains what information the mobile game Crash&Snakeskin (“the game”) collects, how it is used and stored, and how you can access or delete it.
1. Information we collect
When the device is online, the game automatically sends the following anonymous statistics:
- Anonymous ID: a random string created the first time you open the game, used only to tell installations apart. It is not derived from hardware identifiers, the advertising ID or any account, and cannot identify you personally. A separate random session ID is created each time the game is opened.
- Device information: device model, operating system version, screen resolution, memory size, game language, game version and install channel.
- Gameplay data: in-game events and when they happened, such as starting, abandoning and ending a run, take-offs, landings and distance flown, parts picked up, items sold to the travelling merchant and the coins received, hangar upgrades bought or switched (radar, cabin, mount points), achievements earned, viewing the plane, opening the privacy policy, settings changes (language, screen layout), whether “Save to Photos” succeeded, and when the game was opened, sent to the background or closed, with play time.
We do not collect: names, email addresses, phone numbers, precise or approximate location, contacts, the contents of photos or files, the advertising ID, hardware identifiers such as IMEI or Android ID, or payment information.
2. How we use it
- To understand how the game is played: how far players get, where they get stuck and which features are used.
- To tune difficulty and balance, such as coin income and upgrade prices.
- To find bugs and performance problems.
- To count players from each install channel.
The data is not used for advertising or profiling, and it is never sold.
3. Transfer, storage and security
- Data is sent over an encrypted connection (HTTPS) to the developer’s own Google Apps Script web app and stored in a private Google Sheets spreadsheet in the developer’s Google account, which only the developer can access. Google processes this data as the hosting provider; see the Google Privacy Policy. The data may be stored on servers outside your country or region.
- When there is no connection, events are kept in the game’s private storage on your device (up to 500 events) and sent later.
- As with any internet connection, Google’s servers see your IP address when receiving the data. We do not record IP addresses in the spreadsheet.
4. Sharing
We do not sell, rent or share this data with any third party, except where required by law.
5. Retention
Statistics are kept for up to 24 months. After that they are deleted or reduced to aggregate numbers without IDs.
6. Your choices and rights
- Your device’s anonymous ID is shown next to “Privacy Policy” in the game’s Settings panel; tap it to copy. Email it to tianmataistudio@gmail.com and we will delete all data linked to that ID within 30 days. You can request a copy of that data the same way.
- Uninstalling the game removes the anonymous ID and any unsent data from your device. Reinstalling creates a new ID that is not linked to the old one.
- Statistics are part of how the game runs, and there is currently no separate switch to turn them off. If you do not agree with this policy, please do not use the game.
7. Data that stays on your device
Game progress, best distance, coins, gems, your collection, hangar upgrades and settings are stored only on your device and are never uploaded; they are deleted when you uninstall the game. “Save to Photos” (Android 10 and later) saves a picture you choose to save to the “Pictures / CrashAndSnakeskin” album on your device; it is not uploaded either.
8. Permissions
The game only uses two normal permissions: Internet access (to send statistics) and vibration (a short buzz at moments such as hitting a storm cloud). It does not request location, camera, microphone, contacts or storage permissions.
9. Children
The game is not directed at children under 13, and we do not knowingly collect personal information from children. The data the game collects is anonymous; if you believe we have received a child’s personal information, contact us and we will delete it.
10. Changes to this policy
When this policy changes, we will update this page and the effective date above. If ads, in-app purchases or other data-collecting services are added in the future, this policy will be updated first.
11. Contact
