Privacy Policy
Last updated: October 31, 2025
This Privacy Policy describes how GammaLedger ("we", "us", or "our") handles information when you visit gammaledger.com, access documentation, or run the GammaLedger application. Because GammaLedger is primarily a client-side, self-hosted tool, most trading data stays under your control. This Policy explains what we collect, how we use it, and the choices you have.
1. Summary
We strive to minimize data collection. The public website gathers limited technical logs for security and performance. The GammaLedger application stores portfolio data locally in your browser or in locations you configure. We do not sell user data.
2. Information We Collect
Depending on how you interact with GammaLedger, we may collect the following categories of information:
- Website analytics: High-level metrics collected by our hosting provider (for example, aggregate page views, referrers, or error rates). These logs do not contain detailed trade information.
- Repository telemetry: GitHub provides anonymized statistics about downloads, stars, forks, and issues. We use that information to understand community interest.
- Support communications: If you open an issue or pull request, the content you share on GitHub becomes visible to other contributors under GitHub's terms.
- Local application data: When you run the GammaLedger web app, trade data, API keys, and settings are stored locally in your browser (IndexedDB/local storage) or in files that you export. This data never leaves your device unless you choose to sync or share it.
3. How We Use Information
We use collected information to:
- Maintain site stability, detect abuse, and debug technical issues.
- Understand feature adoption and prioritize roadmap items.
- Respond to support requests and collaborate on improvements.
- Publish aggregated community metrics (for example, total downloads) without identifying individual users.
4. Local Storage & Self-Hosted Deployments
GammaLedger is designed so that sensitive portfolio data stays under your control. Key principles include:
- Client-side persistence: Trade history, notes, and analytics remain inside your browser unless you export them.
- Encrypted API keys: Optional brokerage or data-provider keys are encrypted locally before storage. You may delete them at any time.
- Offline capability: Once loaded, the app can run offline, further reducing reliance on external services.
You are responsible for backing up your data and for any compliance obligations that apply to the information you store.
7. Your Choices & Rights
Because the application stores your trading data locally, you can erase it at any time by clearing your browser storage or deleting exported files. For website or repository data you can:
- Adjust browser privacy settings or use privacy-focused extensions to limit analytics.
- Delete or edit GitHub issues or pull requests you previously submitted.
- Contact us to request removal of content that references you in documentation or marketing materials.
8. Security
We follow industry best practices to secure our website, repositories, and documentation. However, no system is completely secure. You are responsible for implementing security safeguards in self-hosted deployments, including access controls, network protections, and encryption for exported backups.
9. Children
GammaLedger is not directed to individuals under 18. We do not knowingly collect personal data from children. If we learn that we have inadvertently collected such information we will delete it promptly.
10. International Users
GammaLedger is developed and maintained by a distributed community. By using the Services you consent to the transfer of technical data to the jurisdictions where our infrastructure or contributors operate. You are responsible for complying with local data-protection regulations that apply to your use case.
11. Changes to This Policy
We may update this Privacy Policy periodically. Material changes will be announced on the GammaLedger website or repository. The "Last updated" date reflects when revisions were published. Your continued use of the Services after an update signifies acceptance of the revised Policy.
12. Contact
For privacy questions or requests, open an issue at the GammaLedger GitHub repository. For sensitive matters you may contact the maintainers directly using the communication channels listed in the repository.
13. Additional Notices
If you deploy GammaLedger alongside third-party integrations, review the privacy policies of those services. Your use of third-party data feeds, brokers, or analytics platforms is subject to their terms and may introduce additional compliance obligations.
