Privacy Policy

This Privacy Policy explains how Yifan Digital LLC ("Yifan Digital", "we", "us") collects, uses, and protects information when you visit yifandigital.com (the "Site") or engage with our services.

1. Who we are

Yifan Digital LLC develops and sells proprietary SaaS products, websites, mobile applications, and other software solutions. These products are offered to individuals and businesses through online subscriptions or one-time purchases. We operate remotely, serve customers online, and are primarily active in the United States and other international markets.

2. Information we collect

• Information you give us. When you contact us — through the inquiry form, email, or other channels — we receive the details you provide, such as your name, email address, company, and project description. The inquiry form composes an email in your own email client; it is not stored on this website.
• Communications. If you correspond with us by email or otherwise, we keep a record of that correspondence.
• Customer account data. If you purchase a subscription or license, we process the information necessary to provide, deliver, and administer your purchase and account, as set out in the applicable product terms.
• Usage data. This Site currently does not set advertising or third-party analytics cookies. Our hosting provider (Google Firebase) may process basic technical logs (such as IP address and request metadata) for security and operational purposes.

3. How we use information

We use the information we collect to:

• Respond to inquiries and provide proposals or quotes;
• Provide, operate, and improve our services and this Site;
• Communicate about projects, support, and (with your consent) occasional updates;
• Comply with legal obligations and protect our rights.

We do not sell or rent personal information, and we do not share it for cross-context behavioral advertising.

4. Legal bases (EEA/UK visitors)

Where the GDPR or UK GDPR applies, we process personal data on the following bases: consent (when you contact us or opt into updates), contract (to deliver services you request), legitimate interests (operating and securing our business), and legal obligation (where required by law).

5. Sharing & service providers

We share information only with service providers who help us operate — for example, email providers and our hosting provider (Google LLC, via Firebase) — under contracts that limit their use of your data. We may also disclose information if required by law or to protect rights, property, or safety.

6. Data retention

We keep inquiry and communication records for as long as needed to respond to you and to manage our business relationship, after which we delete or anonymize them, unless a longer retention period is required by law or an applicable client agreement.

7. Your rights

Depending on where you live, you may have the right to access, correct, delete, or export your personal information, to object to or restrict certain processing, and to withdraw consent. California residents have additional rights under the CCPA/CPRA, including the right to know and to request deletion of personal information; we do not "sell" or "share" personal information as those terms are defined by California law. To exercise any right, email us at the address below. We will verify your request and respond within the time required by applicable law.

8. International transfers

We are based in the United States, and our service providers may process data in the US and other countries. Where required, we rely on appropriate safeguards (such as the EU Standard Contractual Clauses) for transfers of personal data.

9. Children's privacy

The Site and our services are not directed to children under 13 (or under 16 in the EEA/UK), and we do not knowingly collect their personal information.

10. Security

We use reasonable administrative and technical safeguards appropriate to the size and nature of our business. No method of transmission over the Internet is completely secure, and we cannot guarantee absolute security.

11. Changes to this policy

We may update this Privacy Policy from time to time. The "Last updated" date above shows when it was last revised. Material changes will be highlighted on this page.
