Privacy Policy
Last Updated: March 11, 2026
1. Introduction
Welcome to fi50 ("fi50", "we", "our", or "us"). We operate the following websites (collectively, the "Service"):
- fi50.com — Main platform and tool directory
- pdf.fi50.com — PDF tools (convert, merge, split, compress, edit, and more)
- image.fi50.com — Image tools
- zip.fi50.com — File compression tools
This Privacy Policy applies to all of the above and any future subdomains under fi50.com.
This Privacy Policy explains what information we collect, how we use it, and your rights regarding that information. Please read it carefully. If you disagree with its terms, please discontinue use of the Service.
2. Our Core Privacy Principle
fi50 is built on a privacy-first architecture. All file processing happens entirely within your browser — your files are never uploaded to or stored on our servers.
Your documents, images, and PDFs are processed locally on your device.
We never have access to the contents of any file you work with.
No file data is transmitted to fi50 servers at any point.
This is a technical guarantee, not just a policy commitment.
3. Information We Collect
3.1 Files You Process
We do not collect, store, or have access to any files you use with our tools. All file processing — including PDF conversion, merging, splitting, compression, and editing — happens entirely in your browser on your device. Your files never leave your device.
3.2 Information You Voluntarily Provide
We only store personal information if you choose to provide it. This is limited to:
- Username — If you provide a name, we store it to identify your session or preferences.
- Feedback — If you submit feedback or a support message, we store the content of that message along with any name you choose to include.
Providing a username or feedback is entirely optional. If you do not provide this information, we collect nothing that identifies you personally.
3.3 Automatically Collected Technical Data
When you visit fi50.com, we automatically collect limited technical information to keep the Service running smoothly:
- IP address, browser type and version, operating system
- Pages visited, referring URLs, and timestamps
- Device type (desktop, tablet, mobile) and language settings
- Which tools you accessed and session duration
This data is used solely for security, diagnostics, and improving the Service. It is not linked to any personal identity.
3.4 Cookies
We use cookies to enhance your experience:
- Essential cookies — Required for the Service to function (e.g., language preferences).
- Analytics cookies — Help us understand usage patterns (e.g., Google Analytics).
- Preference cookies — Remember your settings across visits.
You can control or disable cookies through your browser settings. Disabling essential cookies may affect Service functionality.
4. How We Use Your Information
We use the information we collect only for the following purposes:
- To operate and maintain the Service.
- To respond to feedback, support requests, and questions you send us.
- To improve and personalize the Service based on usage patterns.
- To detect and prevent technical issues, abuse, or fraud.
- To send administrative notices (e.g., service changes or security alerts).
- To comply with applicable legal obligations.
We do not sell, rent, or share your personal information with third parties for marketing purposes.
5. Data Sharing and Disclosure
We do not sell your data. We may share limited information in these circumstances:
5.1 Service Providers
We use trusted third-party providers for hosting and analytics. They are contractually prohibited from using your data for any purpose other than providing services to us.
5.2 Analytics
We use Google Analytics to understand how users interact with the Service. Analytics data is anonymized and does not include your files or feedback content. You may opt out via the Google Analytics Opt-out Browser Add-on.
5.3 Legal Requirements
We may disclose information if required by law, court order, or to protect the rights, safety, or property of fi50 or its users.
5.4 Business Transfers
In the event of a merger or acquisition, your information may be transferred. We will notify you of any such change.
6. Data Retention
We retain your data only as long as necessary:
- Files — Never stored. All processing is entirely local in your browser; there is nothing to retain or delete.

9. Data Security
We take security seriously and implement measures including:

fi50 is not directed to children under 13 (or 16 in certain jurisdictions). We do not knowingly collect data from children. If you believe a child has submitted information to us, please contact support@fi50.com and we will delete it promptly.
