Privacy Policy

Last Updated: October 11, 2026 · Effective Date: October 11, 2026

Thank you for using PutPack! This Privacy Policy explains how we collect, use, store, and protect your personal information. Please read it carefully to understand our privacy practices.

Personal Information Collection Summary

To provide the core features of this app and the Pro subscription service, we may collect the following personal information:

iOS:

Username/account information: None (no registration required; subscriptions are linked via your Apple ID)
Payment information: Handled by the Apple App Store; we never receive it
Device permissions: Camera, microphone, local network, photo library write access (only for saving videos to your album), location (required only by an integrated third-party SDK; we never obtain your location)
Device identifiers: RevenueCat anonymous purchase receipts (containing no personally identifiable information)

Android:

Account information: Phone number, hashed password
Payment order information: Order ID and payment status returned by Alipay
Verification SMS: Sent via Tencent Cloud SMS, which transmits your phone number
Device permissions: Camera, microphone, local network (saving to the photo album goes through the system media store, so no extra storage permission is needed on Android 10 and above)
Device identifiers: Device ID (used to bind your account to your device)
Sensor information: Accelerometer, gyroscope (used to adapt video orientation while recording)
Network information (SSID, BSSID): the name (SSID) and access-point identifier (BSSID) of the Wi-Fi network you are currently connected to, used to determine the network type and connectivity (for example, to back up automatically only over Wi-Fi); used locally on your device only and never uploaded to our servers
Membership information: Subscription status, expiry date, plan type
Anonymous activity statistics: A randomly generated anonymous identifier created locally, the app version, and app-open dates (used solely to count active users; never linked to any personally identifiable information)
Third-party SDK collection: For payment security purposes, the Alipay SDK may collect your device MAC address, installed app list, IMEI, IMSI, and hardware serial number (only when you initiate an Alipay payment)

Information we do NOT collect:

Your video content, scanned barcode data, location, contacts, address book, call logs, calendar, SMS messages, your phone number (except the number used for registration), or browsing history

Note: On Android we collect only the anonymous activity statistics disclosed above (a random identifier with no personally identifiable information); on iOS we collect no data at all. We do not collect any other device usage records.

Note: When you enable "Back up to Baidu Netdisk" (an optional Pro feature), the videos you choose to back up are uploaded directly to your own Baidu Netdisk account (via the Baidu Netdisk Open Platform). They never pass through our servers and we retain no copy. See "8. Third-Party Services" below.

1. Developer Information

This app is developed and operated by Jiaxing Wendao Apparel Co., Ltd. ("we", "us"). Developer: Liu Yin. If you have any questions about this Privacy Policy, contact us at:

Email: support@putpack.cn

2. Information We Collect

2.1 Information you provide

On iOS, no account registration is required to use any core feature. On Android, a Pro subscription requires registering an account with your phone number; we collect your phone number and hashed password for login verification and device binding.

2.2 Device permissions and sensors

Camera: Used to scan parcel barcodes and record video — the core function of this app. We access the camera only when you actively use the recording feature.

Microphone: Used to record audio together with video. You can revoke this permission at any time in your device settings.

Local network: Used to back up videos to your computer over your local network. This feature is used only when you actively start a backup.

Wi-Fi network information (SSID, BSSID): To determine the current network type (Wi-Fi or cellular) and connectivity before performing a backup, this app reads the name (SSID) and access-point identifier (BSSID) of the wireless network you are connected to via the system's network capability. This information is used only on your device for network detection, is never uploaded to our servers, and is never used to identify you or infer your geographic location.

Photo library write access (iOS): Used to save a recorded video into your system photo album when you actively tap "Save to album". This permission allows writing video files only; it never reads existing content in your album. It is requested once, only when you actively save, and can be turned off at any time in system settings.

Location permission (iOS): None of this app's own features obtain, calculate, or upload your geographical location. This permission is required solely so that a third-party SDK integrated into the app can run (a missing authorization declaration would make that SDK fail during initialization), and its data handling is governed by that SDK developer's privacy policy. You can turn it off at any time in "Settings → Privacy & Security → Location Services".

Sensors (accelerometer, gyroscope): Used to detect device rotation while recording so the video orientation is correct. This data is used only on your device and is never uploaded to any server.

2.3 Subscription and payment information

When you purchase PutPack Pro:

iOS: Payment is processed via Apple In-App Purchase (IAP). Your payment information is collected and managed by Apple; we have no access to it.
Android: Payment is supported via Google Play Billing or Alipay. Google Play payments are managed by Google; Alipay payments are processed by Alipay, and we receive only the order ID and payment status to confirm the transaction — never your bank account or other sensitive information. SMS verification codes on Android are sent via Tencent Cloud SMS.
We use RevenueCat as our subscription management provider. It receives only anonymous purchase receipts from the platform to verify your subscription status (whether subscribed, expiry date, plan type).
RevenueCat does not collect your name, email address, device identifiers, or any other personally identifiable information; it is used solely to verify and manage subscription validity.

2.4 Information we do NOT collect

We explicitly do not collect: your recorded videos, scanned barcode data, location, contacts, address book, call logs, calendar, SMS messages, your phone number (except the number used for registration), or browsing history. We also do not directly collect device identifiers such as IMEI or IMSI (the Alipay SDK may process them only in its payment security context). The location permission requested on iOS exists only because an integrated third-party SDK needs it in order to run; we never obtain, store, or upload your location. Your videos and scan records are stored only on your device, except those you choose to back up to Baidu Netdisk, which are uploaded directly from your device to your own cloud account (see 4.3). On iOS we collect no data at all; on Android we collect only fully anonymous activity statistics (a random anonymous identifier and app-open dates) used to count active users.

3. How We Use Information

3.1 To verify your Pro subscription status and provide the corresponding paid features.

3.2 To improve and optimize the app experience (based on anonymized usage statistics containing no personally identifiable information).

3.3 To respond to your support inquiries and feedback.

4. Information Storage

4.1 By default your recorded videos and scan records are stored only on your device, and we never upload them to any remote server (when you actively enable Baidu Netdisk backup, the videos are uploaded directly from your device to your own cloud account and never pass through our servers — see 4.3).

4.2 The LAN backup feature transfers data over your local network only when you actively enable it and your phone and computer are on the same LAN. Your data never passes through our servers.

4.3 Baidu Netdisk backup (an optional Pro feature): enabled only after you actively turn it on and authorize Baidu Netdisk. Your videos are uploaded directly to your own Baidu Netdisk account (via the Baidu Netdisk Open Platform API) and never pass through or reside on our servers; the Baidu Netdisk access token is stored encrypted only on your device. You can revoke authorization in the app at any time, after which no further uploads occur. Videos once uploaded to Baidu Netdisk are governed by the Baidu Netdisk privacy policy.

4.4 Android account information (phone number, hashed password) and order records are stored on our backend servers for login verification and order management. Subscription verification data (anonymous receipts) is stored via RevenueCat in accordance with RevenueCat's privacy policy. After account deletion, the relevant data is permanently deleted or anonymized within 30 days.

4.5 Uninstalling the app completely and irrecoverably removes all locally stored data from your device.

5. Sharing and Disclosure

5.1 We do not sell, rent, or trade your personal information to any third party.

5.2 We share information only in the following circumstances:

Service providers: We use RevenueCat (subscription management) as a service provider; it receives only anonymous purchase receipts from the platform and never your personally identifiable information. On Android we also use Tencent Cloud SMS (verification code delivery) and Alipay (payment processing).
Legal requirements: We may disclose information when required by law, regulation, legal process, or governmental request.

6. Your Rights

6.1 You can manage the permissions requested by this app (camera, microphone, local network, photo library write access, location) at any time in your device settings.

6.2 You can delete any recorded video or scan record at any time within the app.

6.3 You can manage your Pro subscription at any time: iOS users via Settings → Apple ID → Subscriptions; Android users via the Google Play Subscriptions page or in-app.

6.4 Uninstalling the app completely deletes all locally stored data from your device.

6.5 To request deletion of anonymous data related to subscription verification, contact us using the details below.

6.6 Account deletion

If you registered an Android account, you can request deletion in the app via Settings → Delete Account. You must enter your login password to verify your identity. Once submitted, we complete processing within 30 days: your phone number, hashed password, membership status, and all order records are permanently deleted and cannot be recovered. On iOS there is no account system, so no deletion is needed.

6.7 Revoking Baidu Netdisk authorization

If you enabled "Back up to Baidu Netdisk", you can revoke authorization at any time on the "Baidu Netdisk Backup" page in the app. After revocation we stop uploading to your netdisk and the locally stored access token is immediately invalidated and deleted; files already uploaded to your own Baidu Netdisk must be managed or deleted by you within Baidu Netdisk.

7. Children's Privacy

7.1 This app is not directed at children under the age of 14. We do not knowingly collect personal information from children under 14.

7.2 If we discover that we have inadvertently collected personal information from a child under 14, we will promptly take reasonable steps to delete it from our records.
