PRIVACY POLICY
汇率换算隐私政策
生效日期：2026 年 9 月 4 日 · 适用版本：1.0.0 (Build 3)
我们用清楚的语言说明数据如何被处理。
汇率换算由北京北洋锋行商贸有限公司开发和运营，App 备案号为京ICP备14010251号-4A。本政策适用于当前准备通过 Apple App Store 发布的 iOS 版本。
汇率与推广服务
App 会向 open.er-api.com 与 api.frankfurter.dev 请求公开汇率，并从 www.bjbyfx.com 的固定 HTTPS 路径读取公司推广 JSON、文字和图片。客户端不主动在推广配置请求中附加账号、付费状态、Bundle ID、版本、构建号、语言、设备标识、定位或个人行为数据；服务器和网络服务商仍可能按常规方式处理 IP 地址及请求日志。
境外Google广告
中国大陆以外地区可能使用 Google Mobile Ads 和 UMP。Google SDK 可能按其政策处理粗略位置（例如由 IP 推断）、设备标识、广告数据、产品交互、崩溃、性能及其他诊断数据，用于广告、分析和防止滥用。适用地区会先显示所需的隐私同意流程；当前版本不主动请求 App Tracking Transparency 权限。
订阅与通知
VIP订阅由 Apple StoreKit 处理；我们读取经验证的订阅权益，但不会取得您的付款卡资料。只有在您主动使用提醒功能时才请求通知权限。
删除与保留
您可在 App 内删除收藏、提醒和记录；删除 App 会清除其本地沙盒数据。Apple 与 Google 按各自政策处理其服务数据。
儿童与重要说明
本 App 不以收集儿童个人信息为目的。未成年人应在监护人指导下使用。汇率与估算结果仅供参考，不构成投资、交易或支付建议；实际结算以银行或支付渠道为准。
联系我们与政策更新
如对隐私政策有疑问，请发送邮件至 beiyangfx@163.com。如果功能或数据处理方式发生实质变化，我们会更新本页内容和生效日期。

Currency Converter Privacy Policy
Effective: September 4, 2026 · Applicable version: 1.0.0 (Build 3)
Currency Converter is developed and operated by 北京北洋锋行商贸有限公司. Its mainland China App filing number is 京ICP备14010251号-4A. This policy applies to the current iOS version prepared for distribution through the Apple App Store.
On-device data
No account, name, or contact details are required. Favorites, alerts, travel payment records, preferences, and the last valid promotion configuration stay on the device or in the local App Group container.
Rates and company promotions
The app requests public rates from open.er-api.com and api.frankfurter.dev, and downloads company promotion JSON, text, and images from a fixed HTTPS path on www.bjbyfx.com. The client does not intentionally attach an account, payment status, bundle ID, version, build, language, device identifier, location, or personal behavior data to the promotion configuration request. The server and network providers may still process the IP address and ordinary request logs.
Google ads outside mainland China
Google Mobile Ads and UMP may be used outside mainland China. Under Google's policies, the SDK may process coarse location such as IP-derived region, device identifiers, advertising data, product interaction, crash, performance, and other diagnostics for ads, analytics, and abuse prevention. Required consent is requested before ads. This version does not proactively request App Tracking Transparency permission.
Subscriptions and notifications
VIP subscriptions are processed by Apple StoreKit. We read verified entitlements but do not receive payment-card details. Notification permission is requested only when you use alert features.
Deletion
You can remove favorites, alerts, and records in the app. Deleting the app removes its sandbox data. Apple and Google retain service data under their own policies.
Children and important notice
The app is not designed to collect children's personal information. Minors should use it with guidance from a guardian. Rates and estimates are for reference only and are not investment, trading, or payment advice. Actual settlement is determined by your provider.
Contact and updates
For privacy questions, email beiyangfx@163.com. We will update this page and its effective date if functionality or data handling changes materially.
