Privacy Policy
Last updated: May 24, 2026
This privacy policy describes how Shanghai Yuntai Information Technology Co., Ltd. ("Yuntai", "we", "us") handles information collected through the website yuntai.tech (the "Site"). Individual products listed on this Site (for example GrowBook, OmniEmoji, MakeLineArt, Taplup, 草呢) each have their own privacy policy that governs use of that product. This policy covers the Site itself.
1. Information we collect on this Site
The Site is primarily an informational landing page. We do not require you to create an account or submit personal information to browse it. We may receive:
- Server log information — when you visit the Site, our hosting provider may automatically record standard log data such as IP address, browser type, referring page, and timestamps. This data is used to operate and secure the Site.
- Email correspondence — if you contact us at admin@yuntai.tech, we will receive your email address and the contents of your message so that we can reply.
2. Cookies and analytics
The Site does not currently set first-party tracking cookies and does not run third-party advertising tags. If we add analytics in the future (for example, to understand which products people are most interested in), we will update this page and the data collected will be limited to aggregate, non-identifying usage statistics.
3. How we use information
- To operate, maintain, and improve the Site.
- To respond to inquiries you send us by email.
- To comply with legal obligations.
4. Sharing
We do not sell personal information. We may share limited information with service providers that help us run the Site (for example, our hosting and domain providers), and we may disclose information when required by law.
5. Links to other sites and products
The Site links to our individual products and, in some cases, to third-party platforms (such as Google Play, Pinterest, Reddit, or 小红书). Those services have their own privacy policies and we are not responsible for their practices.
6. Children
The Site is not directed to children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it.
7. Your choices
You may contact us at any time at admin@yuntai.tech to ask what information we hold about you, to correct it, or to request deletion of email correspondence, subject to any retention obligations under applicable law.
8. Changes
We may update this policy from time to time. The "Last updated" date at the top of this page indicates when the policy was most recently changed. Material changes will be highlighted on the Site.
