Terms of Service

Fulminare is an autonomous agent that performs work on your behalf on cloud sandboxes, including running commands, editing files, browsing the web, and calling third-party APIs you connect. You are responsible for the tasks you ask it to perform and for reviewing its output before relying on it.

• Use the Service lawfully and only on systems and data you're authorized to access.
• Keep your credentials secure; you're responsible for activity under your account.
• Don't use the Service to build malware, spam, or to violate others' rights.
• Review agent actions on anything irreversible before it acts on your behalf.

When you connect a third-party app, you authorize Fulminare to access that app's data and take actions using the scopes you grant. You can revoke access at any time in Settings. Your use of connected apps is also governed by their terms.

Fulminare has a free tier and three paid tiers — Lumen, Vivace and Maximus — plus Enterprise, which is arranged separately. Every tier includes the same toolset; what differs is the usage ceiling. Each limit is enforced in real time:

Daily limits reset at midnight UTC; token budgets and overnight-run allowances reset at the start of each calendar month. Hitting a limit pauses new runs until the window resets or you upgrade — it never deletes work in progress. Unused allowance does not roll over.

Payment and renewal

Paid plans are billed monthly in advance through Stripe, our payment processor, and renew automatically until cancelled. We never see or store your card details. Prices are in US dollars and exclude any VAT or sales tax that applies where you are; where we are required to collect it, it is shown before you confirm.

Changing plans, and duplicate subscriptions

One account holds one subscription at a time. To move between paid tiers, use Manage billing in Settings, which switches your existing subscription rather than adding a second one. Fulminare blocks checkout while you already hold a paid plan for exactly this reason.

Our checkout links each open a new subscription. If you reach one by another route — a saved or shared link, a browser back button, a second tab — while a paid plan is already active, you can end up with two subscriptions running at once and be charged for both. We cannot detect or prevent that at the moment of payment.

If it happens, email billing@fulmina.re and we will cancel the duplicate and refund what it charged. We ask you to tell us within 60 days of the charge, because we are not monitoring for duplicates and will not otherwise know. Nothing here limits any statutory right you have to a refund.

Cancelling and refunds

You can cancel at any time from Settings, in two clicks and without contacting us. Cancellation takes effect at the end of the period you have already paid for: you keep your plan and its limits until then, and are not charged again. We do not pro-rate partial months, and fees already paid are non-refundable except where the law says otherwise — including the UK and EU statutory right to cancel a digital purchase within 14 days, which this clause does not limit. If a renewal charge was clearly a mistake, email us and we will refund it.

Failed payments

If a renewal fails, your plan stays active while the card is retried. If it is still unpaid after Stripe's retry schedule ends, the subscription is cancelled and the account returns to the Free tier. Your data and sessions are not deleted.

Changes

We may change limits or pricing. If a change reduces what your current plan includes, or raises its price, we will tell you by email at least 30 days beforehand, and it takes effect at your next renewal — so you can cancel first if you would rather not accept it.

The Service is provided “as is.” Autonomous agents can make mistakes; you are responsible for verifying results. To the maximum extent permitted by law, we disclaim all warranties and limit our liability to the amount you paid in the prior three months.
