本隐私政策描述了TrendMind（"本应用"、"我们"）在您使用我们的自动化交易应用程序时如何处理信息。我们认真对待您的隐私。本政策以清晰的语言撰写，让您确切了解收集了哪些数据、原因及如何保护这些数据。

1. Information We Collect 1. 我们收集的信息

1.1 Information you provide directly

  • Binance API Keys — Your API Key and API Secret for Binance Testnet or Live exchange. These are stored exclusively on your device using encrypted local storage and are never transmitted to our servers.
  • Telegram Bot Token and Chat ID — Used solely to send trade notifications to your own Telegram bot. Stored locally on your device.
  • Strategy Parameters — CE Period, CE Multiplier, EMA Fast, EMA Slow, Risk per Trade percentage. Stored locally on your device.

1.2 Information collected automatically

  • Anonymous usage analytics — We use Firebase Analytics to collect anonymised, aggregated data about app usage patterns (e.g., which screens are visited, how often the bot is started). No personally identifiable information is included. No trade data, API keys, or financial data is ever sent to Firebase.
  • Crash reports — If the app crashes, anonymised diagnostic information (device model, OS version, stack trace) may be sent to Firebase Crashlytics to help us fix bugs. No financial or personal data is included.

1.3 Information we do NOT collect

  • We do not collect your name, email, phone number, or any other personal identifier.
  • We do not collect your trading history, account balances, or financial performance data.
  • We do not collect your location.
  • We do not sell, rent, or share your data with any third party for advertising purposes.

1.1 您直接提供的信息

  • Binance API密钥 — 您的Binance Testnet或实盘交易所API Key和API Secret。这些信息仅存储在您的设备上（使用加密本地存储），绝不传输至我们的服务器。
  • Telegram机器人令牌和聊天ID — 仅用于向您自己的Telegram机器人发送交易通知，存储在您的本地设备上。
  • 策略参数 — CE周期、CE倍数、快速EMA、慢速EMA、每笔交易风险比例，存储在您的本地设备上。

1.2 自动收集的信息

  • 匿名使用分析 — 我们使用Firebase Analytics收集关于应用使用模式的匿名汇总数据（例如访问了哪些页面、机器人启动频率）。不包含任何个人身份信息，也不会将交易数据、API密钥或财务数据发送至Firebase。
  • 崩溃报告 — 如果应用崩溃，可能会将匿名诊断信息（设备型号、系统版本、堆栈跟踪）发送至Firebase Crashlytics以帮助我们修复错误，不包含财务或个人数据。

1.3 我们不收集的信息

  • 我们不收集您的姓名、电子邮件、电话号码或任何其他个人标识符。
  • 我们不收集您的交易历史、账户余额或财务绩效数据。
  • 我们不收集您的位置信息。
  • 我们不出售、出租或以广告目的向任何第三方共享您的数据。

2. How Your API Keys Are Protected 2. 您的API密钥如何被保护

Your Binance API Keys are the most sensitive data the App handles. Here is exactly how they are protected:

  • Keys are stored using the platform's secure local storage (iOS Keychain / macOS Keychain via shared_preferences).
  • Keys are transmitted only to Binance servers (Testnet or Live) using encrypted HTTPS connections to authenticate your orders. They are never sent to our servers or any other third party.
  • The App requests only Spot Trading permissions. You should never enable Withdraw permissions on the API key you provide to TrendMind.
  • Keys are never logged to the console, crash reports, or analytics.

⚠ Important: Enable Spot Trading permission only. Never enable withdrawal permissions on any API key used with TrendMind. We strongly recommend creating a dedicated API key used exclusively for this app.

您的Binance API密钥是本应用处理的最敏感数据。以下是具体的保护方式：

  • 密钥使用平台安全本地存储保存（iOS Keychain / macOS Keychain，通过shared_preferences）。
  • 密钥仅通过加密HTTPS连接传输至Binance服务器（Testnet或实盘）以验证您的订单，绝不发送至我们的服务器或任何其他第三方。
  • 本应用仅请求现货交易权限，您绝不应在提供给TrendMind的API密钥上启用提现权限。
  • 密钥绝不记录到控制台、崩溃报告或分析数据中。

⚠ 重要提示：仅启用现货交易权限，切勿在用于TrendMind的任何API密钥上启用提现权限。我们强烈建议创建专门用于本应用的独立API密钥。

  • Binance — For placing and retrieving orders and account data. Data sent to Binance is governed by Binance's Privacy Policy.
  • Firebase Analytics / Crashlytics (Google) — For anonymous usage analytics and crash reporting. Data sent is anonymised and contains no financial or personal data. Governed by Google's Privacy Policy.
  • Telegram — Only if you configure a Telegram Bot Token. Trade alerts are sent directly from your device to your own Telegram bot. TrendMind has no visibility into your Telegram messages. Governed by Telegram's Privacy Policy.

4. Local Data Storage 4. 本地数据存储

All operational data is stored locally on your device:

  • Trade history — Every buy and sell executed by the bot is recorded in a local SQLite database on your device. This data never leaves your device unless you explicitly copy it.
  • Run logs — Strategy execution logs are stored locally. You can clear them at any time from Settings → Data Management.
  • Bot state — Last cycle date, open positions, equity baseline, and strategy parameters are persisted locally to enable restart recovery.

You can delete all local data by clearing logs in Settings or by uninstalling the App.

所有运营数据均存储在您的本地设备上：

  • 交易历史 — 机器人执行的每笔买卖均记录在您设备上的本地SQLite数据库中，除非您明确复制，否则这些数据不会离开您的设备。
  • 运行日志 — 策略执行日志本地存储，您可随时在设置→数据管理中清除。
  • 机器人状态 — 最后周期日期、未平仓位、净值基准和策略参数本地持久化保存，用于重启恢复。
