Privacy Policy

Sunleaf Scan · Effective November 14, 2026

This policy explains what information Sunleaf Scan ("the app") collects, how it is used and the choices you have. The app is provided by Beijing Chiying Xingtong Technology Co., Ltd. ("we", "us").

Scanning works on your iPhone

Scanning, cropping, enhancement, text recognition, signatures, PDF tools and exports run on your iPhone. Documents you create stay on your device unless you choose to upload them to the cloud. You can use these features without an account.

Information we collect

• Account information. If you sign in with Apple, Google, Facebook or an email code, we receive an account identifier from that service and, when provided, your name and email address. If you use Apple's Hide My Email, we receive a relay address.
• Cloud documents. If you upload documents or turn on automatic upload, we store the page images, document titles and any recognized text you upload.
• Subscription status. Purchases are processed by Apple. We receive transaction information from Apple to confirm your subscription. We never receive your payment card details.
• Technical data. Our servers keep limited logs such as IP address, request time and error details for security and troubleshooting.

We do not use your information for advertising, we do not sell it and we do not track you across other companies' apps or websites.

How we use information

• To create and secure your account and let you sign in on other devices.
• To store, sync and return your cloud documents.
• To provide subscriptions, the free trial and storage limits.
• To send sign-in codes and essential service messages.
• To prevent abuse and keep the service running.

Where data is stored

Cloud documents and account data are stored on servers located in the United States, operated by our hosting provider on our behalf. Sign-in providers (Apple, Google, Facebook) and Apple's App Store process data under their own privacy policies.

Retention and deletion

We keep account data and cloud documents while your account exists. You can delete individual cloud documents in the app at any time. You can delete your account in the app under Me › Settings › Delete Account; this permanently deletes your account and cloud documents from our servers. Server logs are kept for up to 90 days. Documents saved only on your iPhone are not affected and can be removed by deleting them or the app.

Your choices and rights

You can use the app without an account, choose which documents to upload, turn off automatic upload, and request access, correction or deletion of your data by contacting us. Depending on where you live, you may have additional rights under local law; we will respond to requests as required.

Children

The app is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us information, contact us and we will delete it.

Security

Data is transmitted over encrypted connections, access to cloud documents is limited to your account, and sign-in tokens are stored in the iPhone Keychain. No method of storage is completely secure, but we work to protect your information.

Changes

We may update this policy. We will change the effective date above and, for significant changes, notify you in the app.
