二、我们收集的信息
我们仅在为您提供拍摄、水印、定位与拍摄记录同步等功能所必需的范围内收集信息：
1. 拍摄与水印：当您使用拍照或录像功能时，我们会处理您拍摄的照片、视频，用于生成带水印的影像；
2. 位置信息：在您开启定位授权后，我们会获取您的精确地理位置（经纬度），用于在水印中显示拍摄地点与天气信息；
3. 设备信息：拍摄记录会附带您的设备型号与系统版本（形如"iPhone15,3 · iOS 18.0"），用于在记录中标注该影像由何种设备拍摄。我们不收集广告标识符等设备唯一标识；
4. 账号信息：当您通过 Apple 登录（iOS 版）或手机号登录（Android 版）时，我们会收集对应的账号标识，手机号登录还会收集手机号与短信验证码，用于注册、登录与账号数据同步；当您使用 Apple 登录且选择提供姓名时，我们会接收 Apple 返回的姓名作为默认昵称展示；
5. 相册访问：在您主动选择时，我们会读取您相册中的图片（如品牌 Logo），并在您保存时将水印影像写入相册；

Privacy Policy
1. Introduction
Timestamp Camera (the "App") is provided by its operator. We understand how important your personal information is and we work to keep it safe. This policy explains what we collect, how we use, store, share and protect it, and what rights you have. Please read it carefully before using the App; by using the App you accept this policy in full.
2. What we collect
We only collect what is needed to provide shooting, watermarking, location and shot syncing:
1. Photos and video: when you shoot, we process the captured image or video in order to produce the watermarked result;
2. Location: once you grant permission, we read your precise coordinates so the watermark can show where the shot was taken and the local weather;
3. Device details: a shot record carries your device model and OS version (for example "iPhone15,3 · iOS 18.0") so the record shows what the photo was taken with. We do not collect advertising identifiers or any other unique device identifier;
4. Account details: when you sign in with Apple (iOS) or with a phone number (Android) we collect the corresponding identifier — for phone sign-in also the number and the SMS code — in order to register, sign you in and sync your data. If you choose to share your name with Sign in with Apple, we receive it and use it as your default nickname;
5. Photo library: when you choose to, we read images from your library (for example a brand logo) and write watermarked results back when you save;
6. Feedback: when you send feedback we collect what you wrote, the contact details you chose to give and any screenshots you attach.
The App currently offers no paid or subscription service and collects no payment information. We do not collect personal information unrelated to the functions above.
3. How we use it
We use the information above to:
1. Provide the core functions — shooting, watermark compositing, location and weather;
2. Register and sign you in, and sync your data across devices;
3. Run tamper checks that help confirm a photo is an unmodified original;
4. Handle your feedback, provide support and maintain security.
We will not use your personal information for purposes not described here. If a new purpose arises, we will ask for your consent again.
4. Storage and protection
Location: your personal information is stored on servers in the People's Republic of China. One exception: to turn coordinates into a readable address and weather — and to suggest nearby places when you pick a location by hand — the App sends those coordinates (and, for a manual search, what you typed) directly to a mapping provider located in the EU (see "Third-party services"). Those requests carry none of your account details. Apart from that we do not transfer your personal information out of the country.
Retention: we keep your personal information only as long as needed for the purposes described here, unless the law requires otherwise. After that we delete or anonymise it.
Security: we use encrypted transport (HTTPS), access control and other standard technical and organisational measures to guard against unauthorised access, disclosure, alteration or loss.
5. Sharing and disclosure
We do not sell your personal information. We may share what is necessary only in these cases:
1. With your consent;
2. With the partners that make features work — mapping and reverse geocoding, cloud storage and SMS (see "Third-party services");
3. Where disclosure is required by law or by a court or regulator.
We require our partners to keep such information confidential and to protect it appropriately.
6. Third-party services
The App uses the following third-party services, which may collect and process the information they need:
1. Sign in with Apple — provides Apple account sign-in and handles the identifier Apple issues;
2. Mapping and reverse geocoding (Geoapify, servers in the EU) — turns your coordinates into a readable address and weather, and suggests nearby places when you pick a location by hand;
3. SMS (Android phone sign-in only) — delivers sign-in verification codes;
4. Cloud object storage — holds the results, logos and feedback images you upload.
Each third party handles what it collects under its own privacy policy.
7. Your rights
You can exercise these rights in the App:
1. Access and correction — view and change your account details;
2. Withdraw permission — turn off camera, location, photo library or microphone access in system settings (the related features will stop working);
3. Delete your account — go to My account → Delete account. We will delete or anonymise your account and related data. This cannot be undone;
4. Complaints and questions — use Send feedback in the App, or email service@baladuoduo.com.
8. Permissions we request
The App asks for these permissions when you use the matching feature:
· Camera — to take watermarked photos and videos;
· Location — to show the place and weather on the watermark;
· Photo library — to pick a brand logo and to save watermarked results;
· Microphone — to record audio while shooting video.
You can grant or revoke any of these in system settings at any time.
9. Minors
The App is intended for adults. If you are a minor, please use the App and provide personal information under the guidance of a guardian. We protect minors' personal information as the law requires. If a guardian finds that we collected a minor's information without consent, contact us and we will delete it.
10. Changes to this policy
We may update this policy from time to time. We will announce updates in the App and mark the revision date. If a change materially affects your rights, we will tell you more prominently.
11. Contact us
If you have questions, comments or complaints about this policy or about how we handle personal information, use Send feedback in the App or email service@baladuoduo.com. We will respond as soon as we can.
