Privacy Policy

At TanStack.com (the "Site"), your privacy is important to us. This Privacy Policy explains how we collect, use, and protect your information when you access or use our website, products, and services. By using the Site, you agree to the practices described in this Privacy Policy. If you do not agree, please do not use the Site.

1. Information We Collect

We collect information to provide and improve our services. The types of information we may collect include:

• Personal Information: Includes your name, email address, phone number, or other information you provide when you register for an account or interact with the Site.
• Usage Data: Information about how you access and use the Site, including your IP address, browser type, pages visited, and other diagnostic data.
• Cookies and Tracking Technologies: See the "Cookies and Tracking" section below for more details.

2. How We Use Your Information

We use the information we collect for the following purposes:

• To provide, operate, and maintain the Site and our services.
• To improve the user experience and optimize performance.
• To communicate with you, including responding to inquiries and sending updates.
• To comply with legal obligations or enforce our Terms of Service.

3. Cookies and Tracking

We use namethathost.com, operated by TanStack, to understand which companies visit our public pages and which libraries interest them. This tracker uses no cookies or persistent device IDs. It records page paths without query strings and referring website origins. We temporarily process IP addresses through ipapi.is to look up associated company networks. A network match does not identify a person or confirm that a company uses TanStack. Encrypted addresses are held only for delivery and retries, and company lookups stop after 24 hours. Our daily cleanup removes company cache entries older than seven days and activity older than 30 days. This tracker respects Do Not Track and Global Privacy Control.

The Site uses cookies and similar tracking technologies to analyze trends, track user behavior, and gather demographic information. Cookies are small files stored on your device.

You can control cookies:

• Most browsers allow you to block or delete cookies through settings.
• Disabling cookies may affect the functionality of the Site.

4. How We Share Your Information

We do not sell or rent your personal information. However, we may share information in the following circumstances:

• Service Providers: With third parties who help us operate the Site, such as hosting or analytics providers.
• Legal Compliance: If required by law or to respond to legal requests.
• Business Transfers: In connection with a merger, acquisition, or sale of assets.

5. Data Security

We take reasonable measures to protect your information from unauthorized access, use, or disclosure. However, no security measures are completely foolproof, and we cannot guarantee the absolute security of your data.

6. Your Rights

Depending on your location, you may have the following rights regarding your personal information:

• Access: Request access to the personal information we hold about you.
