佳同步（App Store 英文名 Glink，以下简称"本 App"）是一款独立工具，用于在你自己的 Garmin 国区（garmin.cn）账户与国际版（garmin.com / Garmin Connect）账户之间搬运运动活动。本政策说明本 App 如何处理你的信息。
一、本 App 处理的信息
| 类型 | 内容 | 用途 | 存储位置 |
|---|---|---|---|
| Garmin 账户凭证 | 你输入的 Garmin 邮箱与密码 | 仅用于向 Garmin 官方 SSO 完成登录 | 不存储密码。仅登录时提交给 Garmin，不写入本机、不上传任何第三方 |
| OAuth 令牌 | Garmin 登录后签发的访问令牌 | 维持登录状态、调用 Garmin 接口 | 仅存于 iOS 钥匙串（Keychain），不上传、不写入日志 |
| 活动数据 | 活动时间、类型、时长、距离等元数据 | 列表展示、跨区对比、去重判定 | 仅本机（应用沙盒内的数据库），随 App 卸载删除 |
| 活动文件（FIT） | 同步时从一端下载、向另一端上传的原始活动文件 | 完成搬运 | 仅写入系统临时目录，上传完成后立即删除，不进入长期存储 |
| 同步记录 | 每条活动的同步结果与状态 | 供你查看同步历史 | 仅本机，随 App 卸载删除 |
二、本 App 不做的事
- 不设账号体系，不要求注册，不收集姓名、电话、地址

English
Glink (listed as 佳同步 on the China App Store) is an independent utility that moves your own activities between your Garmin China (garmin.cn) account and your Garmin Global (garmin.com / Garmin Connect) account. This policy explains how it handles your information.
1. What the app handles
| Type | Contents | Purpose | Where it lives |
|---|---|---|---|
| Garmin credentials | The Garmin email and password you type | Signing in to Garmin's official SSO | The password is never stored. It is submitted to Garmin at sign-in only, never written to the device, never sent anywhere else |
| OAuth tokens | Access tokens Garmin issues after sign-in | Keeping you signed in, calling Garmin's API | iOS Keychain only. Never uploaded, never logged |
| Activity data | Start time, type, duration, distance and similar metadata | List display, cross-region comparison, de-duplication | On device only (app sandbox database), removed when you delete the app |
| Activity files (FIT) | The raw files downloaded from one side and uploaded to the other | Performing the transfer | Written to the system temporary directory and deleted immediately after upload. They never enter long-term storage |
| Sync history | Per-activity result and status | So you can review what happened | On device only, removed when you delete the app |
2. What the app does not do
- No accounts, no registration; no name, phone number, or address collected
- Your Garmin password is never stored
- No third-party advertising or analytics SDK of any kind (the app uses Apple frameworks only)
- Your activity data, tokens, and everything else are never sent to the developer or any third party
- No location, contacts, or HealthKit data
- No in-app purchases, no payment information
3. Every server the app talks to
| Endpoint | Purpose | Carries your data? |
|---|---|---|
sso.garmin.cn / Garmin Global SSO |
Authentication | Yes — your credentials go to Garmin's own service |
| Garmin Connect API (garmin.cn / garmin.com) | Reading and uploading your activities | Yes — your activity data, to Garmin's own service |
thegarth.s3.amazonaws.com/oauth_consumer.json |
Fetching the public OAuth client parameters Garmin's flow requires | No. A read-only public config file; the request carries none of your data |
Nothing else. The developer operates no backend and cannot see your data.
4. Background sync
With background sync enabled, the app uses Apple's BGTaskScheduler to run at times the system schedules. Background runs behave exactly like foreground runs and collect nothing extra.
5. Deleting your data
- Sign out: clears that region's tokens from the Keychain
- Delete the app: removes all on-device data (activity cache, sync history, Keychain entries)
- Data inside your Garmin account is controlled by Garmin; use Garmin's own channels
6. Children's privacy
Not directed at children under 13; no information is knowingly collected from them.
7. Changes
The "Last updated" date at the top changes when this policy does.

9. Trademarks
This app is an independent companion app and is not affiliated with, endorsed by, or sponsored by Garmin Ltd. "Garmin", "Garmin Connect", garmin.cn, and garmin.com are trademarks of their respective owners.
