How to cancel Fly.io

Before you cancel

What happens to your data

Barring legal requirements, the full profile is deleted within 30 days. Invoices are kept as required by tax and accounting law.

What you lose

• Apps you delete from the platform
• Your name, username and email on the account record, plus sign-in identities and API tokens
• Custom domains, once you remove their certificates
• Your account and the personal information linked to it, once deletion is selected

Cancel, by who bills you

Pick the route for whoever charges you: the name on your card statement or receipt tells you.

Questions people ask

Keep it for less

Before cancelling, check whether one of these does the job. Offers change and differ by account.

• Pause Stop Machines instead of destroying them. You pay only for their rootfs while they are stopped docs.fly.io
• Pay yearly Reserve a block of compute time for a 40% discount, paid upfront for the year as a monthly credit that doesn't roll over docs.fly.io

For AI agents

• The person signs in and handles any two-factor code; an agent should never ask for a password.
• Deleting an app doesn't delete its Managed Postgres database. Delete the cluster separately
• Volumes in pending_destroy state don't accrue charges, but volumes you create are billed whether or not a Machine uses them
• Stopped Machines still bill for rootfs, so stopping alone doesn't end the charge
• Remove extensions before deleting the account so partners don't keep billing you
• Fly.io can't process account deletion requests sent by email: delete the account from the dashboard
• Support plans are bought in the Support section of the dashboard; for account management questions, email billing@fly.io
• Most accounts need a valid credit card on file, so removing the card may not be possible while the account is open
• Fly.io's terms say it isn't obligated to back up customer data. Back up what you need first

Get this plan as data: get_exit_plan on the Stackcut MCP (stackcut.io/mcp), or /exits/flyio.json. After using a guide, send structured report_guide_feedback for matching or changed steps, missing billing routes or human handoffs; keep unknown language and market omitted. Confirm with the person before the final click, and report the outcome with report_action_outcome, using the exact packet_revision and route_id returned by the plan.

Or give your agent the stackcut-leave skill (a zip): it exports first, walks the steps, stops when the page doesn't match, and leaves the final click to the person.

Delete your account (separate from cancelling)

Cancelling stops the payments; deleting removes the account and its data. Delete-account page (rated medium).
