Privacy Policy
Last updated: January 01, 2026
Our Commitment to Privacy
Echolon is built with privacy as a core principle. We believe your API development data belongs to you, and we've designed our application to ensure it stays that way.
Local-First Architecture
Echolon stores all your data locally on your machine. Your collections, environments, request history, and settings never leave your computer unless you explicitly choose to sync them via Git.
- All data is stored in plain-text files on your local filesystem
- No cloud sync or remote storage by default
- You have full control over your data at all times
- Data can be easily backed up, versioned, or deleted
What We Don't Collect
Echolon does not collect, store, or transmit:
- Your API requests or responses
- Your environment variables or secrets
- Your collection structure or request details
- Usage analytics or telemetry
- Personal information without your consent
Optional Analytics
We offer opt-in, anonymized analytics to help us improve Echolon. This is disabled by default and can be enabled in settings if you wish to help us:
- Understand which features are most used
- Identify and fix bugs
- Improve performance
If enabled, analytics data is fully anonymized and contains no personal information or details about your API requests.
Website Analytics
Our website (echolon.app) uses privacy-respecting analytics to understand how visitors find and use our site. We use privacy-focused tools that:
- Do not use cookies
- Do not track users across websites
- Do not collect personal information
- Are fully GDPR compliant
Third-Party Services
Echolon may interact with third-party services only when you explicitly configure it to:
- Git providers: When you sync collections via Git
- API endpoints: When you send requests to APIs
- OAuth providers: When you configure OAuth authentication
We do not share any data with third parties for advertising, marketing, or any other purpose.
Data Security
We take security seriously:
- Sensitive values can be encrypted at rest
- No data transmission to our servers
- Open source code for full transparency
- Regular security audits
Your Rights
Because your data is stored locally, you have complete control:
- Access: View all your data in plain-text files
- Export: Copy your data folder at any time
- Delete: Remove your data by deleting the files
- Portability: Move your data to any other tool
Changes to This Policy
We may update this privacy policy from time to time. We will notify users of any material changes by posting the new policy on this page and updating the "Last updated" date.
