At jsonl.co, your privacy is our top priority. This policy explains how we handle your data.

No File Data Collection

All JSONL file processing happens entirely within your browser. Your files are never uploaded to our servers. We do not collect, store, or have access to any file content you open or edit on jsonl.co.

Local Storage

We may use browser local storage to save your preferences such as language selection and theme settings. This data remains on your device and is never transmitted to any server.

Analytics

We may use privacy-friendly analytics to understand general usage patterns such as page views and feature usage. No personally identifiable information is collected through analytics.

Cookies

We use minimal cookies necessary for site functionality, such as language preference. We do not use tracking cookies or share cookie data with third parties.

Third-Party Services

If you choose to log in using OAuth providers (Google, GitHub), those services have their own privacy policies. We only receive basic profile information (name, email, avatar) necessary for account creation.
