Privacy Policy

Welcome to Study Tool Hub ("we," "our," or "us"). We are committed to protecting your personal information and your right to privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our website (buffettools.com/) and use our online tools.

1. Information We Collect

• Personal Information: When you register for an account (Free or Pro Member), we collect basic information such as your email address and username.
• Uploaded Files: To provide our services (e.g., Image Compression, PDF Conversion, AI Photo Retouching), you upload files to our servers.
• Payment Information: If you upgrade to our Pro plan, your payment details are processed directly by our secure third-party payment gateways (e.g., PayPal, Stripe). We do not store your full credit card information on our servers.
• Usage Data: We automatically collect standard log data, such as your IP address, browser type, and operating system, to ensure our site runs smoothly.

2. How We Handle Your Files (Data Security & Retention)

Your privacy and the security of your documents are our top priorities. We adhere to a strict automated deletion policy:

• Temporary Storage: Files uploaded for processing are kept only temporarily on our secure servers to perform the requested action.
• Automatic Deletion: All original uploaded files and processed output files are automatically and permanently deleted from our servers within 1 to 2 hours after processing.
• No Data Mining: We do not view, analyze, extract, or share your uploaded files with third parties, except as strictly necessary to process the tool’s function.

3. Third-Party API Services

To provide advanced features like AI Photo Retouch & Enhancer, we utilize industry-leading third-party Artificial Intelligence APIs (e.g., Replicate API). When you use these specific AI tools, your image is securely transmitted to these API providers solely for the purpose of enhancement, and is subject to their strict privacy and non-retention policies.

4. Cookies and Tracking

We use essential cookies to maintain your login session, manage Pro feature access, and remember your site preferences (such as Dark Mode). You can manage or disable cookies through your web browser settings, though doing so may affect your ability to log in or use certain tools.

5. Your Data Rights

You have the right to access, update, or request the deletion of your personal information at any time. If you wish to delete your Study Tool Hub account and all associated data, please contact our support team.
