Account & Billing

Sign-in methods, token storage, the event-triggered validation model, subscription gating, and the grace period.

Last updated 2026-05-23 · Applies to NotBot 1.3.4+

NotBot signs into your MellowState account and validates your subscription before letting you print. This page covers sign-in methods, the subscription model, and how NotBot handles expiration and the grace period.

MellowState account

NotBot uses your MellowState account to sign in. You can sign up with:

  • Email and password
  • Google
  • Apple

Whichever method you used to create the account is the one you continue to use. A MellowState license is per person or per company. One license covers multiple platform shops, so if you run several Whatnot accounts you do not need separate NotBot subscriptions for each one.

Sign-in flow

Click Login with MellowState on the welcome screen. Your default web browser opens to the MellowState sign-in page so you can use saved passwords and existing Google or Apple sessions. After you authorize NotBot, the browser hands the session back to the app, and NotBot stays signed in across restarts.

Your sign-in is stored securely using your operating system's built-in credential storage. If your credential storage is locked or unavailable, NotBot falls back to storing the sign-in locally on disk and shows a warning so you can fix the underlying issue.

Staying signed in

NotBot keeps your session fresh in the background. You should never have to think about it. If something goes wrong (your sign-in expires, or your subscription lapses), NotBot prompts you to sign in again.

Subscription gating

You need an active or trial subscription, plus NotBot access on your account, to print. The valid subscription states are active, trial, inactive, and expired.

If your account is missing NotBot access, an Access Revoked screen appears and prompts you to subscribe. If you have access but no active subscription, NotBot refuses to send pending labels and shows a sign-in prompt the next time it tries to process the queue. Events are still tracked, but labels stay queued until you re-authorize.

Grace period

If your subscription check fails because of a connection issue or a temporary MellowState service problem, NotBot enters a grace period instead of cutting you off immediately. During grace:

  • NotBot continues to work normally, including printing.
  • A warning banner shows how much time is left.
  • Background retries try to refresh your session automatically.

The grace window exists so a flaky internet connection mid-show doesn't disable your printer. If your sign-in is actually invalid (not just unreachable), NotBot shows a sign-in prompt and stops printing right away. No grace in that case.

Payment failures

If a payment fails, your subscription moves to inactive or expired and NotBot disables printing on the next check. The retry policy for failed payments is handled by the MellowState billing platform, not by NotBot itself, so the exact retry window can change. Check your MellowState billing page for the current status if you have a question about a specific payment.

Signing out

Use the Logout control in the top bar of the app. This clears your stored sign-in. You will need to sign in again to use NotBot.
