Marketra Rate Curve · Google Play
A plain-language data inventory for the Marketra Rate Curve Android app.
Effective 4 August 2026 · 生效日期 2026 年 8 月 4 日
Marketra shows an independently calculated United States Treasury 10-year minus 2-year Constant Maturity Treasury rate spread, recent official observations, bundled educational material, and an on-device last-success snapshot.
This release has no account, anonymous device identity, advertising, analytics SDK, notification permission, financial-account connection, transaction feature, subscription, or remote question processing.
The app requests the public Marketra Rate Curve API. Cloudflare, as hosting and network infrastructure, may process standard request metadata such as IP address, request time, user agent, and security signals needed to deliver and protect the service.
The app can store the latest successful market dataset, its retrieval time, language, and theme on the device. Marketra does not place those preferences or snapshots in a user database.
On-device data remains until app storage is cleared or the app is uninstalled. Infrastructure security logs follow the hosting provider's applicable retention controls. Because this release creates no Marketra account or server-side user profile, there is no account-deletion workflow.

Marketra 展示独立计算的美国国债 10 年期减 2 年期固定期限国债利差、近期官方观测、内置教育内容及本机最后成功快照。
本版本不含账号、匿名设备身份、广告、分析 SDK、通知权限、金融账户连接、交易、订阅或远程问题处理。
应用会请求公开的 Marketra 利率曲线 API。Cloudflare 作为托管与网络基础设施，可能处理交付和保护服务所需的标准请求元数据，例如 IP 地址、请求时间、用户代理及安全信号。
应用可在本机保存最近一次成功的市场数据、获取时间、语言及主题。Marketra 不会把这些偏好或快照写入用户数据库。
本机数据会保留至用户清除应用数据或卸载应用。基础设施安全日志遵循托管服务商适用的保留控制。本版本不创建 Marketra 账号或服务端用户档案，因此没有账号删除流程。
