Privacy Policy
1. Introduction
At HexDecoder, we take your privacy seriously. This Privacy Policy explains how we handle (or rather, don't handle) your data when you use our hex encoding and decoding tools.
Our core principle: Your data is yours. We never see it, we never store it, and we never transmit it.
2. Information We Do NOT Collect
Unlike most web services, HexDecoder is designed to collect as little information as possible:
- ✓ Your encoded/decoded data: All processing happens in your browser. We never see what you encode or decode.
- ✓ Personal identification: We don't require accounts, emails, or any personal information.
- ✓ File contents: Files you upload are processed locally in your browser and never sent to our servers.
- ✓ Conversion history: Your conversion history is stored locally in your browser only. We can't access it.
- ✓ Cookies for tracking: We don't use cookies to track your behavior across websites.
3. Information We DO Collect
We collect minimal, anonymized data to improve our service:
3.1 Anonymous Analytics
We use Google Analytics to understand how people use HexDecoder:
- Page views and navigation patterns
- Browser type and version
- Device type (desktop/mobile/tablet)
- Geographic location (country/city level only)
- Time spent on pages
Important: This data is anonymized and aggregated. We cannot identify individual users.
3.2 Essential Cookies
We only use essential cookies:
- Theme preference: Remembers if you prefer dark or light mode
- Analytics consent: Stores your choice about analytics (if we add opt-in)
These cookies are stored locally in your browser and contain no personal information.
3.3 Local Storage
We use browser Local Storage for:
- Conversion history: Your recent conversions (stored on your device only)
- User preferences: Theme, layout preferences, etc.
This data never leaves your device and can be cleared anytime from your browser settings.
4. How We Process Your Data
Client-Side Processing Only: All hex encoding, decoding, and conversion operations happen entirely in your browser using JavaScript. Your data never touches our servers.
What This Means:
- ✅ Complete privacy - we physically cannot see your data
- ✅ Works offline - no internet required after initial page load
- ✅ Instant processing - no server round trips
- ✅ Safe for sensitive data - your data never leaves your computer
5. Third-Party Services
We use minimal third-party services:
5.1 Google Analytics
We use Google Analytics for anonymous usage statistics. Google may use cookies and collect anonymous data according to their privacy policy.

5.2 Google AdSense
We display ads through Google AdSense to support our free service. Google may use cookies for ad personalization.
Ad Settings: You can control ad personalization at Google Ad Settings
5.3 Hosting Provider
Our website is hosted on secure servers. The hosting provider may collect standard server logs (IP addresses, access times) for security and performance monitoring.
6. Data Security
Since we don't collect or store your sensitive data, there's minimal security risk. However, we still take precautions:
- HTTPS encryption: All connections are encrypted
- No data transmission: Your encoded/decoded data never leaves your browser
- Regular updates: We keep our code and dependencies updated
- Security headers: We use modern security headers (CSP, X-Frame-Options, etc.)

Under GDPR, CCPA, and other privacy regulations, you have rights regarding your data:
- Right to access: Request what data we have (spoiler: almost nothing)
- Right to deletion: Request deletion of your data
- Right to opt-out: Disable analytics tracking
- Right to data portability: Your local data can be exported from browser storage

8. Children's Privacy
HexDecoder is suitable for all ages. We don't knowingly collect personal information from anyone, including children under 13.
9. International Users
HexDecoder is accessible worldwide. Since we process data in your browser, your data stays in your jurisdiction. Analytics data may be processed by Google in the United States.
10. Do Not Track (DNT)
We respect browser Do Not Track signals. If your browser sends a DNT signal, we will honor it and disable analytics tracking where technically feasible.
11. Changes to This Privacy Policy
We may update this Privacy Policy occasionally. Changes will be posted on this page with an updated "Last Updated" date.
