9F VPN

Effective Date: October 6, 2026
Last Updated: October 7, 2026

9F Technologies LLC ("we", "us", "our"), a company registered in the United States, operates the 9F VPN apps and related services (the "Service"). This policy explains exactly what information the Service collects, why, how long we keep it, and how you can delete it.

In short: we do not log the websites you visit, your DNS queries, or the content of your traffic, and we do not store your IP address. We do not sell your data and the Service contains no advertising or tracking SDKs. To run accounts, subscriptions and the network, we keep a small amount of device, account and connection-session information, described below.

1. What we never collect

The websites, apps or services you access through the VPN
DNS queries you make through the VPN
The content of your traffic
Your IP address. Our infrastructure sees it while handling a request and uses it at that moment to estimate your country, city and network provider (see 2.2), but we do not store it. To prevent abuse, we may keep a one-way keyed hash of it for up to 48 hours; the address cannot be recovered from the hash.
Advertising identifiers. The Service has no ads and does not track you across other companies' apps or websites.

Our VPN servers are configured with traffic/access logging disabled, and their system logs are kept in memory only.

2. What we collect and why

2.1 Device information

A random identifier generated by the app (not your hardware serial number), device model, operating system version, app version, language and time zone. We use it to recognise your device, enforce the device limit of your account (5 devices for VIP), troubleshoot, prevent abuse, and produce aggregated statistics.

2.2 Approximate location and network

When the app contacts our API, we derive your country, city and network provider (ISP / ASN) from the request. We use this to recommend nearby servers and for aggregated statistics. This is stored with your device record; the IP address itself is not.

2.3 Connection sessions

When a VPN connection starts and ends, the app reports the server region you connected to and how long the session lasted. We use this to show whether a device is online, to apply subscription and device limits, and to measure service reliability. We do not record what you do during a session.

Our VPN servers also count how much data each device transfers per day (a byte total only, not what the data was). We use it to apply the free plan's daily high-speed allowance and to show you today's usage.

2.4 Account information (optional)

If you create an account, we store your email address (for sign-in codes) or the identifier provided by Sign in with Apple, your account ID, creation date and the list of devices bound to the account.

2.5 Subscription information

Subscription status, product and expiry date, received from Apple via RevenueCat. Payments are processed by Apple; we never receive your card details.

2.6 Support messages

If you contact us by email, Telegram or Facebook, we receive the information you choose to send.

2.7 Stored only on your device

App settings and favourite servers are stored locally on your device and are not uploaded.

3. Service providers

Provider	Purpose
Apple	App Store distribution, in-app purchases, Sign in with Apple
RevenueCat	Subscription status and receipt validation
Cloudflare	Hosting of our API, website and content delivery
Resend	Sending sign-in codes to your email address
Server hosting providers	Data-centre hosting for our VPN servers

These providers process data only to deliver their service to us. We do not sell, rent or trade your information.

4. How long we keep data

Device and account records: while you use the Service, or until you delete your account.
"Currently online" status: removed when the session ends, and automatically after at most 1 hour.
Daily data totals: 40 days.
Security events (for example clock tampering detected by the app): 30 days.
Sign-in codes: deleted once used or after they expire.

5. Your choices and rights

Delete your data in the app: open the Account page and tap Delete Account. If you are signed in, this deletes your account record, your email / Apple sign-in link and the records of the devices bound to the account. If you are not signed in, it deletes the record of the current device.
You can also email us to request deletion; we may ask you to confirm it is your account or device.
You may ask us what data we hold about you, or ask us to correct it, at any time.
Uninstalling the app removes all data stored locally on your device.

6. Legal requests

We may disclose the limited information described in section 2 if we are legally required to. We cannot disclose browsing history, DNS queries, traffic content or stored IP addresses, because we do not have them.

7. Security

Traffic between the app and our servers is encrypted. Our API is served over TLS, and access to our systems is restricted to authorised personnel.

8. Children

The Service is not directed to children under 13, and we do not knowingly collect their personal information. If you believe a child has provided us data, contact us and we will delete it.

9. Changes

If we change this policy, we will post the new version here and update the date above. Material changes will also be announced in the app.

9F Technologies LLC（以下称"我们"）是一家在美国注册的公司，负责运营 9F VPN 应用及相关服务（以下称"本服务"）。本政策说明本服务具体收集哪些信息、用途、保存多久，以及您如何删除这些信息。

简而言之：我们不记录您访问的网站、DNS 查询或流量内容，也不保存您的 IP 地址。我们不出售您的数据，本服务不含任何广告或追踪 SDK。为了运行账户、订阅和网络，我们会保存少量设备、账户和连接会话信息，详见下文。

1. 我们从不收集的信息

您通过 VPN 访问的网站、应用或服务
您通过 VPN 发出的 DNS 查询
您的流量内容
您的 IP 地址。我们的基础设施在处理请求时会看到它，并当场用它估算您所在的国家、城市和网络运营商（见 2.2），但不会保存它。为防止滥用，我们可能保存它的单向加密哈希最长 48 小时，无法从哈希还原出 IP 地址。
广告标识符。本服务没有广告，也不会在其他公司的应用或网站间追踪您。

我们的 VPN 服务器已关闭流量 / 访问日志，系统日志只保存在内存中。

2. 我们收集的信息及用途

2.1 设备信息

应用生成的随机标识（不是硬件序列号）、设备型号、系统版本、应用版本、语言和时区。用于识别您的设备、执行账户的设备数上限（VIP 为 5 台）、排查问题、防止滥用和生成汇总统计。

2.2 大致位置与网络

应用访问我们的接口时，我们会根据该请求推断您所在的国家、城市和网络运营商（ISP / ASN），用于推荐就近的服务器和汇总统计。这些信息会与设备记录一起保存，但 IP 地址本身不保存。

2.3 连接会话

VPN 连接开始和结束时，应用会上报您连接的服务器地区和本次连接的时长。用于显示设备是否在线、执行订阅和设备数限制、衡量服务的稳定性。我们不记录您在连接期间做了什么。

我们的 VPN 服务器还会统计每台设备每天传输的数据量（只有字节总数，不包括数据内容）。用于执行免费版每日高速流量额度，并向您显示今日用量。

2.4 账户信息（可选）

如果您创建账户，我们会保存您的邮箱地址（用于接收登录验证码）或"通过 Apple 登录"提供的标识，以及账户 ID、创建日期和绑定到该账户的设备列表。

2.5 订阅信息

通过 RevenueCat 从 Apple 获取的订阅状态、产品和到期时间。付款由 Apple 处理，我们不会接触您的银行卡信息。

2.6 客服沟通

RevenueCat	订阅状态与收据验证
Cloudflare	托管我们的接口、网站及内容分发

"当前在线"状态：连接结束时删除，最长 1 小时后自动删除。
每日流量统计：保存 40 天。

您可以随时询问我们保存了您的哪些数据，或要求更正。
卸载应用会删除保存在您设备上的全部数据。

6. 法律要求

在法律要求时，我们可能会披露第 2 节所述的有限信息。我们无法提供浏览记录、DNS 查询、流量内容或 IP 地址，因为我们根本没有这些数据。

7. 安全

应用与我们服务器之间的流量是加密的；我们的接口通过 TLS 提供服务，系统访问权限仅限授权人员。
