Privacy Policy
This policy explains what ChaoNiu Doc Scanner (“the app”, “we”) does with your information in the global edition distributed through chaoniudoc.app. The Chinese mainland edition on chaoniudoc.com is operated by a different company under a separate policy; this policy does not apply there.
1. Who is responsible
The data controller for the global edition is ChainMotion Future Technology Limited (a Hong Kong company, CR No. 77542324), registered office Flat D07, 8/F, Phase 2, Kai Tak Factory Building, 99 King Fuk Street, San Po Kong, Hong Kong. You can reach us at [email protected].
2. What we collect
- Files you process. Photos, documents, audio and video links you submit to be scanned, converted, recognised, enhanced or analysed.
- Account data. If you sign in, the identifier of the sign-in method you chose, and your purchase and credit history.
- Technical data. Device model, operating system version, app version, language, crash reports and request logs needed to run and debug the service.
- Payment data. Handled by the app store or payment provider you use. We receive the transaction result, not your full card number.
We do not sell personal data, and we do not use your documents to train models.
3. Why we process it, and on what basis
To deliver the processing you asked for, to operate accounts, credits and purchases, to prevent abuse, to meet legal obligations, and to fix faults. Processing a file is carried out to perform the contract you entered into when you used the feature; logs and abuse prevention rest on our legitimate interest in running a reliable service; where we ask for consent, you can withdraw it at any time.
4. Where your data is processed, and how long we keep it
Some processing happens on your device. Tasks that need server capacity — recognition, format conversion, transcription, image generation — are sent to our servers. [TODO — to be confirmed: the countries and regions where the global edition's processing servers are located]
Uploaded source files and generated results are kept only as long as needed to deliver and re-download the result, then deleted. [TODO — to be confirmed: the exact retention window for uploaded files and generated results] Technical logs, which do not contain file contents, are kept for a shorter window. [TODO — to be confirmed: the retention window for technical logs]
If you are in the EEA, the UK or another region with transfer rules, any transfer outside your region is made under the safeguards that apply there, such as standard contractual clauses.
5. Who else sees it
We use service providers for hosting, content delivery, crash reporting and payment processing, and sub-processors for some AI processing tasks. They act on our instructions and only for the purposes above. [TODO — to be confirmed: the list of sub-processors and the countries they operate in]
6. Your choices and rights
You can ask us to access, correct, export or delete your personal data, withdraw consent, or object to processing, by writing to [email protected]. You can delete individual documents in the app at any time. To delete your whole account, use the account deletion option in the app or email us; we confirm deletion requests and then remove the account and its stored files.
Depending on where you live you may also have the right to complain to your local data protection authority. In Hong Kong that is the Office of the Privacy Commissioner for Personal Data.
7. Children
The app is not directed at children under 13, or under the minimum age in your country if that is higher. We do not knowingly collect their data.
8. Security
Transfers use HTTPS. Access to production systems is limited to the people who operate them. No system is perfectly secure, so please avoid uploading material you could not risk having exposed.
9. Changes
If this policy changes in a way that affects you, we will update this page and the “last updated” date above, and where required we will tell you in the app.
