Do it yourself

Cancel Backblaze yourself

TLDR: Cancel in your account before the renewal date. Billing stops except amounts already past due, payments are not refunded unless a written agreement says otherwise, and deleting the account removes the files still stored in it.

Cancel before the renewal date

Backblaze is set to renew.

  1. 01Cancel in your account before the renewal date.

The terms name help pages for Computer Backup and for B2 Cloud Storage, and they do not print those web addresses. Unless you have a contract for a set term, you can cancel and delete the account at any time. A subscription renews at the current list price for the same length unless you cancel first. After you cancel, they stop billing except past-due amounts and any early-end or cancel fees. The account stays reachable until you delete it. Deleting it removes the email and the files still in it. Payments are not refunded unless the payments page, a written deal, or an order form says otherwise.

Mail a notice

You want it on paper.

  1. 01Write that you are cancelling, and include the email on the account.
  2. 02Mail it by certified mail to Backblaze, Inc., 2261 Market Street, STE 81006, Attn: Legal Department, San Francisco, CA 94114.

The terms say notices go there, or to legal@backblaze.com. A dispute notice before arbitration uses the same street. Cancel in the account as well.

How to know it worked

  • Billing stops except amounts already past due and any end fees.
  • The account stays open until you delete it.

Watch out for

  • Deleting the account removes the files still stored in it.

Backblaze refunds

  • Payments are not refunded unless the payments page, a written agreement, or an order form says otherwise.

Cancelling Backblaze

What people ask about Backblaze.

How do I cancel Backblaze?

Cancel in your account before the renewal date. The terms point to help pages for Computer Backup and B2 and do not print those links. Mail goes to Backblaze, Inc., 2261 Market Street, STE 81006, Attn: Legal Department, San Francisco, CA 94114.

Do I get the rest of the year back?

The terms say payments are not refunded unless a payments page, a written deal, or an order form says otherwise.

Can you cancel Backblaze without me logging in?

Yes. The notice goes to Backblaze in writing, so it does not depend on you reaching a cancel button inside your account. A lost password or a locked account does not stop it.

Does the letter ask them to delete my data?

Yes. It asks the company to erase the personal data it holds on you where it has no lawful reason to keep it, and to confirm in writing once it has.
