How to Cancel Firebase (Downgrade Blaze, Stop Billing)

How to fix it

Try these in order — the most common fix is first.

1. 1. Downgrade to Spark in the console

   Copy steps
   1. Firebase console > Settings (gear) > Usage and billing > Details & settings
   2. Choose to modify the plan and select Spark
   Did this fix it? Yes No

2. 2. Unlink the billing account

   Copy steps
   1. Google Cloud console > Billing > Account management
   2. Disconnect the project; this also downgrades it to Spark
   3. Verify the project no longer shows a linked account
   Did this fix it? Yes No

3. 3. Know what stops working

   Copy steps
   1. Cloud Functions can't be deployed, non-default Storage buckets and Realtime Database instances become inaccessible, paid Google Cloud services stop
   2. Data in them is not deleted; upgrade again to regain access
   Did this fix it? Yes No

4. 4. Delete the project if you're done

   1. Project settings > Delete project, after exporting any data you need
   Did this fix it? Yes No

5. 5. Refunds

   1. No official refund policy was verified; billing is pay-as-you-go, so contact Google Cloud billing support about disputed charges
   Did this fix it? Yes No

Symptoms

You want to stop being charged, or avoid charges from a project you no longer use.

Why it happens

• Billing is attached to the Google Cloud project, not a Firebase subscription
• Budget alerts don't stop usage
• Linking a billing account re-upgrades the project to Blaze
