Privacy Policy

Last updated September 23, 2026

The short version

  • NightJar runs on your computer. Your projects, commands, logs and environment variables never leave it.
  • The app needs no account. No analytics, no telemetry, and the website sets no cookies.
  • An account on this site is optional. It only shows the Pro keys bought with your email.
  • If you buy Pro, Polar handles the payment. We get your email so we can support your license.
  • Activating a key sends the key and your computer’s name to Polar. Nothing else.

Who we are

NightJar is made by [Your name or company] (“we”, “us”). We decide how the personal data described here is used. Questions or requests go to [contact email].

What stays on your computer

The NightJar app runs a local server on 127.0.0.1, which is not reachable from other machines. Everything it works with stays on your computer and is never sent to us:

What we collect, and why

When you buy NightJar Pro

Polar Software, Inc. is the merchant of record: it runs the checkout, takes payment, handles tax and sends your receipt and license key. Polar shares your name, email address, billing country and order details with us. We use them to deliver and support your license, handle refunds, and keep the records tax law requires. We never see your full card details.

When you activate, check or remove a license key

The app talks to Polar’s license API at api.polar.sh. It sends:

The app re-checks your key at most once every 14 days. Polar replies with the key’s status, its expiry date if any, and the email it belongs to. The app saves that reply in ~/.nightjar/license.json, readable only by your user account. Removing the key in Settings deletes that file.

When you create an account on this website

An account is optional and only lets you see the Pro keys bought with your email address, and which machines they are activated on. Supabase, Inc. runs sign-in for us. It stores:

To show your keys, our server looks up your confirmed email address in Polar. Your keys are read live from Polar each time and are not copied into your account. Your browser keeps the sign-in session in local storage, not a cookie; signing out removes it. To delete your account, email us.

When you email us

We keep your message and address so we can answer and follow up.

When you visit this website

The site has no analytics, no cookies, no ads and no third-party fonts or scripts. Only the account page talks to another service: Supabase, for sign-in. Our hosting provider, [hosting provider], may keep standard server logs (IP address, browser, pages requested) for security and reliability.

What we never do

Who else processes your data

Polar is based in the United States, so purchase and license data may be processed there.

How long we keep it

Your rights

You can ask us for a copy of your data, or ask us to correct or delete it. You can also object to how we use it. Email [contact email]. We may need to keep purchase records the law requires. If you are in the EU, UK or a similar jurisdiction, you can also complain to your data protection authority.

Children

NightJar is a developer tool and is not directed at children under 16.

Changes

If this policy changes, we update this page and the date at the top. If a change affects how we use data you already gave us, we will say so here before it takes effect.
