本应用不设账号、不要求注册、不收集任何可识别您身份的信息，也不包含任何广告或第三方追踪组件。您在应用内输入的全部内容只保存在您自己的设备上。唯一会离开设备的信息，是为了取得行情数据而必须发送给公开财经数据服务的股票／期货代码等查询参数——这一点在下文第三节逐条列明，不做任何隐瞒。
本应用的行情、财务、日历等数据全部直接向公开的第三方财经数据服务请求，不经过开发者的任何中转服务器。发起请求时，以下信息会随请求到达对方服务器：
AAPL、0700.HK、600519.SS、BTCUSDT）。这些代码会以明文出现在请求地址中。请注意：由于这些是第三方运营的服务，开发者无法控制、也无法向您保证对方是否记录、保留或如何使用上述请求日志。如果您不希望自己的关注标的出现在第三方的访问日志中，请不要使用本应用。

自 1.0 (13) 起，所有请求均以本 App 自身名义发出（User-Agent 标识 SNTWET-MarketResearch，并附本项目的联系邮箱），不冒充浏览器，不发送 Referer/Origin 头。
此外，应用内的图表界面由设备本机的一个回环（loopback）网页服务提供，地址为 http://127.0.0.1。该服务只在您的设备内部通信，不监听局域网、不接受外部连接，数据从不离开设备。
关于第三方隐私政策：上述服务方各自的隐私政策由其自行发布，不在本政策约束范围内。本应用只是向其公开接口发起只读请求，与其没有任何数据共享或商业合作关系。
以下数据只写入 iOS 本地存储（NSUserDefaults / SharedPreferences），既不上传，也不备份到开发者处：
删除本应用即会一并删除上述全部本地数据。您也可以在应用内逐条删除自选与手动录入的数值。
本应用面向成年人的市场资讯阅读需求，不面向 13 岁以下儿童设计，也不会有意收集儿童的任何信息（事实上本应用不收集任何人的身份信息）。
由于开发者不持有您的任何数据，通常意义上的“查询／导出／删除我的数据”请求在本应用中没有对应的服务器端对象——所有数据都在您手里，删除应用即彻底删除。若您对本政策有疑问，或希望确认某项具体行为，请发邮件至 sntwet@gmail.com，开发者会在合理时间内答复。
本应用仅展示公开市场数据并在设备上进行技术指标计算。所有数据均为延时数据，非交易所实时授权行情，可能存在延迟、缺失或错误。应用内的任何数字、图表或文字都不构成投资建议、要约或推荐，也不代表对任何证券未来价格的预测。任何投资决策及其后果由您自行承担。
本政策如有实质性变更，将更新本页顶部的“最近更新”日期，并在必要时于应用更新说明中提示。
EnglishThis app has no user accounts, requires no registration, and collects no personally identifiable information. It contains no advertising and no third-party tracking components. Everything you enter stays on your own device. The only information that leaves your device is the ticker symbol you are looking up, which must be sent to public financial-data services in order to retrieve quotes. Section 3 lists every one of those services by name.
All market, fundamental and calendar data is requested directly from public third-party financial data services. There is no relay server operated by the developer. When a request is made, the following reaches the third party's servers:
AAPL, 0700.HK, 600519.SS, BTCUSDT). These appear in clear text in the request URL.Please note: because these are services operated by third parties, the developer cannot control and cannot warrant whether, or for how long, those parties log or retain such requests. If you do not want the symbols you follow to appear in a third party's access logs, please do not use this app.
The table below lists every host this version of the app actually sends network requests to (verified against the source code on 2026-08-18):
| Provider | Host | Purpose |
|---|---|---|
| Sina Finance | vip.stock.finance.sina.com.cnstock.finance.sina.com.cnstock2.finance.sina.com.cnquotes.sina.cn | Delayed quotes (A-shares, Hong Kong, US), sector lists, futures daily bars, A-share fundamentals |
| Tencent Finance | ifzq.gtimg.cnweb.ifzq.gtimg.cnqt.gtimg.cn | Historical and intraday candles; delayed quotes (CN/HK/US) |
| East Money | push2delay.eastmoney.comsearchapi.eastmoney.comdatacenter.eastmoney.com | Delayed quotes, symbol search suggestions, HK fundamentals |
| Yahoo Finance | query1.finance.yahoo.comquery2.finance.yahoo.com | US quotes and historical candles |
| StockAnalysis.com | stockanalysis.com | US fundamentals and valuation metrics |
| Baidu Gushitong | gushitong.baidu.comfinance.baidu.com | Valuation history percentiles (PE/PB) for A-shares and Hong Kong stocks |
| Cboe | cdn.cboe.com | Delayed US options chain quotes (open interest, volume, implied volatility) |
| NYSE | www.nyse.com | Trade-halt notices |
| U.S. SEC EDGAR | www.sec.govdata.sec.gov | Dates and form types of U.S. company event filings (8-K); only the date and form type are read, filing documents are not downloaded |
| FRED (Federal Reserve Bank of St. Louis) | fred.stlouisfed.org | U.S. Treasury yields |
| Binance | api.binance.com | Bitcoin price and daily bars (price display only) |
Since 1.0 (13), every request identifies the app truthfully (User-Agent SNTWET-MarketResearch, together with the project contact e-mail); the app never impersonates a browser and never sends Referer/Origin headers.
In addition, the charting interface is served by a loopback web server running inside the app on the device itself, at http://127.0.0.1. It communicates only within your device, does not listen on the local network, accepts no external connections, and no data leaves the device through it.
Third-party policies: each provider publishes its own privacy policy, which is outside the scope of this document. This app only issues read-only requests to their public endpoints; there is no data-sharing arrangement or commercial relationship between the developer and any of them.
The following is written only to local iOS storage (NSUserDefaults). It is never uploaded and never backed up to the developer:
Deleting the app deletes all of the above. You can also remove watchlist entries and typed figures individually inside the app.
This app is intended for adults reading market information. It is not directed to children under 13 and does not knowingly collect information from children — indeed it collects identity information from no one.
Because the developer holds none of your data, the usual "access / export / delete my data" requests have no server-side object to act on: all data is in your hands, and deleting the app erases it completely. For any question about this policy, write to sntwet@gmail.com and the developer will respond within a reasonable time.
This app displays public market data and performs technical-indicator calculations on the device. All data is delayed; it is not exchange-licensed real-time data and may be late, incomplete or wrong. No number, chart or sentence in this app constitutes investment advice, an offer, or a recommendation, nor a prediction of any security's future price. All investment decisions and their consequences are yours alone.
Material changes will be reflected in the "Last updated" date at the top of this page and, where appropriate, noted in the app's release notes.
