Cookie Policy

Last updated: February 2026
Draft — review before real-world launch. This document is a good-faith working draft written to describe how Billune actually operates. It is not a substitute for legal advice. Before you rely on it in production, please have it reviewed by counsel qualified in your jurisdiction.

This Cookie Policy explains what cookies and similar technologies Billune uses, why we use them, and how you can control them.

1. What Cookies We Use

Billune uses a small, deliberately-minimal set of cookies:

Strictly Necessary

  • access_token — httpOnly, Secure, SameSite=None. Holds your signed JWT session (7 days). Without it you can't stay logged in.
  • session_token — httpOnly, Secure, SameSite=None. Holds your Emergent Google OAuth session (7 days) if you signed in with Google.

Preference (client-side storage, not a cookie)

  • billune-theme — stored in your browser's localStorage to remember whether you prefer light or dark theme. Nothing sensitive.

Third-Party Cookies

  • When you check out via Stripe, Stripe sets its own cookies on the checkout page for fraud prevention. Those cookies are governed by Stripe's privacy policy.
  • We do not use Google Analytics, Facebook Pixel, or any third-party advertising cookies.

2. Email Open Tracking

Invoice emails you send from Billune include a 1×1 tracking pixel so we can tell you when a client opens your invoice ("read receipts"). This is a common transactional-email technique and does not use cookies. See the Privacy Policy for retention details.

3. How to Control Cookies

  • You can delete or block cookies via your browser settings.
  • If you block the strictly-necessary cookies above, you will not be able to stay signed in.
  • To reset your theme preference, clear localStorage for this site.

4. Changes

If we add a new cookie or tracking technology, we will update this page and, if it is more than strictly-necessary, ask for your consent first.
