Beijing Xiaoyu Changxiang Technology Co., Ltd. (“we”) explains in this policy how the FlashScan app (“the app”) handles your information.
Please read this policy before you use the app. Using the app means you agree to it.
Scanning, cropping, filters, signatures, stamps, PDF export and document management run on your device. Documents, signatures and stamps created by those features stay on your device. We do not upload document content for those features.
When you use an account, credits or advanced features, we collect only what that feature needs:
To improve the product, the app uses the Umeng analytics SDK. It collects device model, operating system version, device identifiers, network type, and statistics such as app launches and feature use. Those statistics do not include your documents, signatures or stamps.
Feedback: tapping feedback opens the mail app on your device. The message may include the system version, system language and app version. That information is sent only if you send the email, and you can edit or delete it first.
2.1 We use the information only to:
2.2 Permissions the app may request:
You can turn these permissions off in system settings. Related features may then be unavailable.
3.1 We share information with others only in these cases:
3.2 Other than the cases above, we do not share, transfer or publicly disclose your information.
3.3 Documents on your device stay under your control. If you share a document through the system share sheet, that is your own action.
The app includes only the WeChat Open SDK and the Umeng analytics SDK. Information is provided to an SDK only when you use the related feature.
5.1 Scanned documents, signatures and stamps are stored on your device by default. Uninstalling the app deletes that local data. Please back it up first.
5.2 Account, credit, order and invite records are stored on our servers so we can sign you in, grant credits and keep records. Purchase records are kept as required.
5.3 A page image uploaded for an advanced feature is used only for that request and is deleted when processing ends. It is not added to your document library and is not used for anything else. If processing fails, the credits charged for that page are returned.
5.4 Device and usage information collected by Umeng is stored under Umeng’s own privacy policy.
5.5 Please keep your device and account safe:
In the app you can view and edit your nickname, view credit history, and bind a phone number. Documents on the device are yours to view, edit or delete.
You can close your account from Account. Closing takes effect immediately. Sign-in identity, nickname, profile photo and credit balance are deleted and cannot be restored. Purchase records are kept as required by law. Closing the account does not delete scanned documents on this device.
To access or correct account information, or to ask about analytics or advanced features, email us at the address below.
7.1 The app is intended for adults. If you are a minor, use it with a guardian.
7.2 If you are a minor, use an account, buy credits or use advanced features only with a guardian’s consent. If the guardian does not agree, do not register or buy.
8.1 Local scanning still does not upload documents. Accounts, credit purchases and advanced features collect information as described in this policy. Depending on how people use the app and on what our technology suppliers can provide, we may add or remove advanced features. What is available is what the app shows at the time.
8.2 If we later collect information for a new purpose or share it with a new recipient, we will update this policy. Changes that affect accounts, payment or uploading document content will be shown in the app.
9.1 We may update this policy and publish the latest version in the app.
9.2 Material changes, such as a new kind of information collection, will be brought to your attention in the app.
9.3 Please check this policy from time to time.

We will reply within 15 business days.
