Privacy Policy for Print Layout

Effective date: [7 23, 2026]

Ding'an Shuzhi Technology (Tianjin) Co., Ltd.("we", "us", or "our") operates the Print Layout mobile application (the "App"). This Privacy Policy explains how we collect, use, share, and protect information when you use the App.

1. Information We Collect

1.1 Account Information

If you choose to sign in with an email verification code, we collect your email address to create or authenticate your account and to send the verification code.

If you choose to sign in with Google, we receive information supplied by Google that is necessary to authenticate you, such as your Google account identifier, email address, and basic profile information made available through the Google sign-in service.

1.2 Purchase Information

If you make an in-app purchase, payment processing is handled by Google Play. We do not receive or store your full payment card number or other payment account credentials.

We may receive and process purchase-related information, such as product identifiers, purchase tokens, subscription status, transaction status, and order-related identifiers, to provide purchased features, verify entitlements, prevent fraud, and restore purchases.

1.3 Technical and Security Information

When you connect to our services, we may process information necessary to operate and secure the service, including IP address, request time, device or app version, authentication/session identifiers, and error or security logs.

1.4 Documents and Files

The App may allow you to select PDF documents from your device for printing-layout functionality. Unless a feature clearly states that a document is uploaded or synchronized, documents you select are processed locally on your device and are not sent to our servers.

2. How We Use Information

We use information to:

- create and authenticate your account;
- send and validate email verification codes;
- provide Google sign-in;
- provide, maintain, and improve the App and its account services;
- verify purchases and provide purchased or subscribed features;
- prevent fraud, abuse, unauthorized access, and security incidents;
- respond to support requests and communicate important service information;
- comply with legal obligations and enforce our terms.

3. Legal Basis for Processing

Where applicable law requires a legal basis, we process personal information to perform our contract with you, comply with legal obligations, pursue legitimate interests such as service security and fraud prevention, and, where required, based on your consent.

4. How We Share Information

We do not sell your personal information.

We share information only as necessary with:

- Google, when you use Google Sign-In or make purchases through Google Play;
- service providers that host, secure, or operate our authentication and application services;
- authorities or other parties when required by law, to protect rights and safety, or to investigate fraud or security incidents;
- a successor organization in connection with a merger, acquisition, or sale of assets, subject to applicable law.

5. Data Retention

We retain account, authentication, purchase, and security information only for as long as necessary to provide the App, maintain security, comply with legal obligations, resolve disputes, and enforce agreements.

You may request deletion of your account and associated personal information by contacting us at [privacy@your-domain.com]. Some information may be retained where required for legal, accounting, fraud-prevention, security, or transaction-record purposes.

6. Data Security

We use reasonable technical and organizational measures designed to protect personal information, including encrypted transmission over HTTPS and access controls. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

7. Your Rights and Choices

Depending on your location, you may have rights to access, correct, delete, restrict, object to, or receive a copy of your personal information. You may also withdraw consent where processing is based on consent.

To exercise these rights, contact us at [privacy@your-domain.com]. We may need to verify your identity before fulfilling a request.

8. Children's Privacy

The App is not directed to children under the age required by applicable law to use the service independently. We do not knowingly collect personal information from children without legally required consent. If you believe a child has provided personal information to us, contact us at [privacy@your-domain.com].

9. International Data Transfers

Your information may be processed in countries other than the country where you live. Where required, we use appropriate safeguards for international transfers of personal information.

10. Third-Party Services

Google Sign-In and Google Play Billing are governed by Google's own privacy policies and terms. We encourage you to review Google's Privacy Policy at:
