Privacy Policy

FileSize.org is designed with privacy as a fundamental principle. We do not collect, store, or process any personal information. Specifically:

• We don't collect names, email addresses, or contact information
• We don't track IP addresses or location data
• We don't use cookies or browser fingerprinting
• We don't collect usage statistics or behavioral data
• We don't access or upload your files

All FileSize.org tools operate entirely within your web browser using JavaScript. This means:

• Converters: Unit conversions are calculated locally using JavaScript math functions
• Calculators: File size estimations are computed in your browser
• No server processing: Your inputs are never sent to our servers
• No data retention: When you refresh or leave the page, all data is cleared

Like most websites, our web server automatically creates standard access logs that may include:

• Date and time of page requests
• Pages visited on our site
• Referring website (if applicable)
• Browser type and operating system
• Anonymized IP addresses

These logs are used solely for:

• Diagnosing technical issues
• Preventing abuse and ensuring security
• Understanding general traffic patterns (not individual behavior)

Server logs are automatically deleted after 30 days and are never shared with third parties.

FileSize.org minimizes the use of third-party services:

• No analytics services: We don't use Google Analytics or similar tracking services
• No advertising: We don't display ads or use ad networks
• No social media widgets: No Facebook, Twitter, or other social tracking
• No CDNs for tracking: We self-host all resources

The only third-party requests are for:

• Fonts: Google Fonts (if used) - Google's privacy policy applies to font requests

Since we don't collect personal data, there's no personal information to secure. However, we still implement security best practices:

• HTTPS encryption for all pages
• Regular security updates to our web server
• No database means no risk of data breaches
• Client-side processing means your data never leaves your device

FileSize.org is safe for users of all ages. Since we don't collect any personal information, we don't knowingly collect information from children under 13. Our tools are educational and can be safely used in school environments.

FileSize.org is accessible worldwide and complies with privacy regulations including:

• GDPR (Europe): We're compliant by not collecting personal data
• CCPA (California): No personal information to sell or share
• COPPA (Children): Safe for users under 13

Since we don't collect personal data, traditional data subject rights are not applicable. However, you always have the right to:

• Use our tools anonymously without providing any information
• Verify our privacy practices using browser developer tools
• Contact us with any privacy concerns
• Request information about our data practices

We may update this privacy policy to reflect changes in our practices or for legal reasons. Any changes will be posted on this page with an updated revision date. We encourage you to review this policy periodically.

If we ever decide to collect personal information, we will:

• Update this policy before making any changes
• Clearly explain what data we collect and why
• Obtain consent where required
• Never apply changes retroactively
