The Perchlight app

Perchlight runs on your computer. We (the Perchlight project) don't run any server for the app and don't receive any of your data.

• Your Cloudflare sign-in (an API token, or a "Sign in with Cloudflare" token) is stored encrypted on your computer with your operating system's key store, and is sent only to Cloudflare.
• Your projects and screens are stored only on your computer.
• Your data (KV values, D1 rows, mailing-list subscribers) goes directly between your computer and Cloudflare's API. It never passes through us.
• The app has no analytics, tracking or crash reporting.

When you use "Sign in with Cloudflare", Cloudflare's own privacy policy applies to that sign-in. Perchlight asks only for the permissions it needs: reading your account details, and editing Workers KV and D1.
