Privacy Policy

Last updated: 15 February 2026

What LanternKit does

LanternKit provides free developer tools that run in your browser. Most tools process data entirely on your device — your input never leaves your browser.

Data we collect

We do not collect personal data. Specifically:

  • No user accounts or sign-ups (currently).
  • No analytics or tracking scripts.
  • No cookies, except essential ones if introduced later.
  • No data you enter into our tools is sent to any server — all processing happens in your browser.

Hosting

LanternKit is hosted on Cloudflare. Cloudflare may log standard request metadata (IP addresses, request timestamps) as part of their infrastructure. See Cloudflare's Privacy Policy for details.

Theme preference

We store your light/dark theme preference in your browser's local storage. This data never leaves your device and is not sent to any server.

Future changes

If we introduce features that require accounts, analytics, or server-side processing, this policy will be updated before those features go live. We will never retroactively change how your existing data is handled.
