BilledFlow keeps cookies to a minimum. We use only the cookies required to keep you signed in; we do not use advertising or cross-site tracking cookies, and we do not sell any data to third-party ad networks.
| Name | Purpose | Type | Duration |
|---|---|---|---|
| sb-*-auth-token | Keeps you signed in between visits. | Strictly necessary | Session / until sign out |

We use Vercel Analytics and Speed Insights to understand overall traffic and page performance. Both are cookieless: they measure aggregated page views and load times without setting a cookie or tracking you individually across sites.
Since every cookie BilledFlow sets is required for you to sign in and stay signed in, there is no optional cookie category to opt out of. Blocking these cookies in your browser will prevent you from logging in.
