How to cancel Firebase Inc by mail
Get your account details together
Firebase Inc will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Write the cancellation request
Postbye turns the request into a finished English letter headed “Subject: Subscription termination – Firebase Inc”: close the Firebase Inc account, stop every charge and reply in writing.
Post the letter
Address the envelope to Firebase Inc, Mountain View, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Keep the proof of delivery
It shows the date Firebase Inc received your letter. Check your next statement: no Firebase Inc charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Firebase Inc, check these
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
