Last Updated: April 22, 2026

Welcome to base64online.net. Your privacy is important to us. This Privacy Policy explains how we handle information when you use our Base64 encoder/decoder tool.

1. Data Processing

100% Client-Side Processing: All encoding and decoding operations happen entirely in your web browser using JavaScript. We do not have servers that process, store, or transmit your data. Your text, files, and images never leave your device.

2. Information We Do NOT Collect

We do not collect, store, or process:

• Text you encode or decode
• Files or images you upload
• Base64 strings you input or generate
• Any personally identifiable information (PII) through our tool

3. Information We MAY Collect

We may collect non-personal information through third-party services:

• Browser type and version

4. Cookies

Our website may use cookies from third-party services (Google Analytics, Google AdSense). We do not set cookies directly for tracking or storing your tool usage data.

You can control cookies through your browser settings. Note that blocking cookies may affect website functionality and analytics.

5. Third-Party Links

Our website may contain links to external sites (e.g., documentation, resources). We are not responsible for the privacy practices of these third-party websites. Please review their privacy policies independently.

6. Children's Privacy

Our service is not directed to children under 13 years of age. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us immediately.

7. Data Security

Since all tool operations are performed client-side in your browser, we do not transmit or store your data on our servers. This provides maximum security and privacy for your sensitive information.

8. Your Rights (GDPR / CCPA)

If you are located in the European Union (GDPR) or California (CCPA), you have rights regarding your personal data:

• Right to access your data
• Right to rectification (correction)
• Right to erasure (deletion)

Since we do not collect or store personal data from our tool, most rights apply to data collected by third-party services (Google Analytics, Google AdSense). To exercise these rights, please contact the respective service providers or contact us for assistance.

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last Updated" date. We encourage you to review this policy periodically.
