Please read this policy carefully before using our platform. By using ToolHub, you acknowledge that you have read, understood, and agreed to all terms of this policy.
1Information We Collect
When you use our platform, we may collect the following types of information: • Usage data: Anonymous statistics including pages visited, tools used, access times, browser type, and operating system (collected via Google Analytics). • Uploaded files: Files you voluntarily upload for tool processing, used solely to perform the operation you requested and deleted immediately after completion. • Communications: Your name, email address, and message content when you contact us via the contact form or email. • Technical data: Anonymized IP addresses, session cookies, and other necessary technical identifiers. We do not collect sensitive personal information such as ID numbers, financial account details, or passwords.
2How We Use Your Information
Information we collect is used only for the following legitimate purposes: • Service delivery: Processing your uploaded files and returning the results of requested tool operations. • Product improvement: Analyzing usage statistics to improve tool performance and user experience. • System security: Monitoring for abnormal access, preventing abuse and security attacks. • User communication: Responding to your inquiries only when you initiate contact. We do not sell, rent, or share your personal information with any third parties for commercial or marketing purposes.
3File Processing & Storage
File security is one of our most important commitments: • Files are transferred to our servers via HTTPS encryption. • Files are used solely for the specific tool operation you requested (e.g., PDF conversion, image compression). • Uploaded files and generated result files are automatically deleted from our servers within 1 hour of processing completion. • We do not analyze file content, create file indexes, or use files for machine learning training. • Server storage uses encryption protection with strictly controlled access permissions.
4Cookies & Tracking
We use the following types of cookies: • Essential cookies: Required for basic website functionality (e.g., theme preferences, language settings). These cannot be disabled. • Analytics cookies (optional): Collected anonymously via Google Analytics to help us understand feature usage. You can disable these in your browser settings without affecting core functionality. We do not use advertising tracking cookies or cross-site tracking technologies.
5Third-Party Services
Our platform integrates the following third-party services, which may independently collect data: • Google Analytics (traffic analysis): Collects anonymous usage statistics. See Google's Privacy Policy for details. • Cloudflare (CDN & security): Provides speed optimization and DDoS protection. See Cloudflare's Privacy Policy for details. We have data processing agreements with these providers to ensure your data is appropriately protected. We do not share user data with any other third parties.
6Data Security Measures
We implement the following technical and organizational measures to protect your data: • Site-wide HTTPS encryption to prevent data interception during transmission. • Encrypted server-side data storage with strict access controls. • Regular security audits and vulnerability scanning with timely patching. • Automatic file deletion mechanism to minimize data retention time. Although we make every effort to protect your information, no internet transmission can be guaranteed 100% secure. Please avoid processing extremely sensitive files through our platform.
