Privacy-First Promise: Nidra is built on a local-first architecture. Your API requests, collections, and environment data never leave your computer. We collect only anonymous usage analytics to improve the product.
1. Information We Collect
Data That Stays Local
The following data is stored exclusively on your machine and never transmitted to our servers:
- API request collections and history
- Environment variables and configurations
- Request conduits and automation workflows
- Response data and test results
- All application settings and preferences
Anonymous Analytics
To understand how features are used and improve Nidra, we collect anonymous usage data including:
- Feature usage statistics (e.g., "user created a collection", "user sent a request")
- Application performance metrics (e.g., startup time, response rendering speed)
- Error reports and crash diagnostics (containing no personal data)
- Operating system version and basic system information
We do NOT collect:
- API endpoints or URLs you test
- Request or response payloads
- Headers, authentication tokens, or credentials
- Environment variable names or values
- Any personally identifiable information
License Verification
During the 30-day premium feature trial and license activation, we collect:
- License key (if provided)
- Machine identifier (a hashed hardware fingerprint)
- License activation timestamp
License checks occur automatically every 14 days to verify your premium trial status or paid license. This requires a brief internet connection but transmits no usage data. The free version does not require license verification.
2. How We Use Your Information
We use the limited data we collect to:
- Improve the product: Understand which features are used and where users encounter issues
- Fix bugs: Diagnose crashes and errors to improve stability
- Verify licenses: Ensure trial periods and paid licenses are valid
- Communicate updates: If you opt in to our mailing list, we'll send product announcements (you can unsubscribe anytime)
3. Data Storage and Security
Local Storage
All your API testing data is stored locally on your machine in:
- Windows:
%APPDATA%\nidra - macOS:
~/Library/Application Support/nidra - Linux:
~/.config/nidra
This data is not encrypted by the application (it's stored as plain JSON files). We recommend using full-disk encryption if you work with sensitive APIs.
Analytics Storage
Anonymous analytics are sent to our analytics provider (PostHog) and stored for 90 days. These logs contain no personally identifiable information.
4. Third-Party Services
Nidra uses the following third-party services:
- PostHog: Anonymous product analytics (self-hosted instance)
- GitHub: Software distribution and automatic updates
We do not share your data with advertisers, data brokers, or other third parties.
5. Your Rights
Because Nidra is local-first, you have complete control over your data:
- Access: All your data is stored in plain files on your machine (see paths above)
- Deletion: Uninstall Nidra and delete the application data folder to remove all traces
- Opt-out of analytics: You can disable analytics in Settings → Privacy (feature coming soon)
- Data portability: Export collections to JSON, cURL, or other formats
6. Children's Privacy
Nidra is intended for professional developers and is not directed at children under 13. We do not knowingly collect data from children.
7. Changes to This Policy
We may update this privacy policy as Nidra evolves. When we make significant changes, we'll notify you via:
- In-app notification on next launch
- Email (if you've subscribed to our mailing list)
- Update notes in the changelog
Continued use of Nidra after policy changes constitutes acceptance of the updated terms.

Our commitment: Nidra will always be local-first. We will never move to a cloud-required model or sell your data. Your API testing stays private, always.
