Privacy notice
Last updated: 2026-11-07 · 隐私说明（中文摘要见每节末）
Short version: ChinaGo has no account, no passport upload, no face recognition and no location tracking. We keep an anonymous device ID on your phone, the photos you choose to scan for 7 days, and the counters needed for the free daily limits. Emergency cards and guides work without any of that.
一句话：ChinaGo 不要账号、不收护照、不做人脸、不取定位。只在你手机上存一个匿名设备号，扫描照片最多保留 7 天，并记录每日免费次数。应急卡与图解不依赖这些数据。
1. What we collect, why, and for how long
| Data | Why | Kept |
|---|---|---|
| Anonymous device ID (random UUID in your browser's local storage) | Count free daily turns and remember your Pass on this device. It is not linked to your name, phone or email. | Until you clear site data. You can reset it any time from your browser settings. |
| Photos you take or upload in “Shoot” | Read the text in the photo and return what it says and what to do. Stored on our server only to serve the result back to your device. | Deleted automatically after 7 days. EXIF (including GPS) is stripped before the file is written. |
| Text you type or speak in “Talk” | Translate it. Text is sent to the translation provider you have configured and is not kept in our database. | Not stored. Only an anonymous counter (“one talk turn”) is kept. |
| Usage counters and guide opens | Free daily limits, abuse prevention, and aggregated product statistics. | Counters are per day; aggregate records kept up to 12 months. |
| Human help request (Pass only, optional) | We call the shop, hotel or hospital in Chinese for you. You choose what to write and which contact to leave. | Until the ticket is closed, then deleted within 30 days. |
采集范围：匿名设备号、你主动拍摄/上传的照片（7 天）、对话文本（不落库）、每日次数、图解打开记录、可选的人工协助工单。护照号、人脸、精确位置、通讯录、短信一律不采集。
2. What we never collect
- Passport, ID card or visa numbers
- Face images or biometric templates
- Precise location (GPS). There is no location permission request; the app works without it.
- Contacts, SMS, call logs, photo library beyond the single image you choose
不采集：护照/身份证/签证号、人脸与生物特征、精确位置、通讯录、短信、通话记录、以及你未主动选择的那张照片之外的相册内容。
3. Where data is stored
Photos, counters and tickets are stored on servers located in mainland China. We do not replicate this data to overseas nodes. Translation and OCR may call a configured third-party API; if no key is configured, ChinaGo runs entirely on its built-in offline phrasebook and never sends your photo off the device for AI processing.
照片、次数与工单存放在中国境内服务器，不同步到境外节点。翻译/识别可能调用已配置的第三方接口；未配置 key 时走内置离线词库，照片不因 AI 处理离开本机。
4. Your choices and deletion
- Delete your local identity: clear site data in your browser. A new anonymous ID is created next time.
- Delete server-side records: email the contact below with your invite code (shown under “Me”). We delete the device record, photos and tickets within 7 working days.
- No consent, no scan: you can use Emergency, Guides and the phrasebook without ever taking a photo.
删除方式：清除浏览器站点数据即可重置本地身份；如需删除服务端记录，用“我的”页面里的邀请码联系下方邮箱，7 个工作日内删除设备记录、照片与工单。应急、图解、短句库不拍照也能用。
5. Children
ChinaGo is not directed to children under 14. Do not submit a child's photo or personal information.
本产品不面向 14 岁以下儿童，请勿提交儿童照片或个人信息。
6. Contact
