Refund Policy

We refund the difference when we charge you more than our Terms allow, including:

• a duplicate charge for the same billing period;
• a fee calculated with the wrong price, the wrong token count or the wrong percentage;
• a fee on requests that failed because of a fault on our side;
• a fee on usage from an API key you had already revoked, or on usage after you cancelled;
• any charge made after you cancelled, other than the final charge described below.

Tell us within 60 days of the charge, or later where the law gives you a longer right. When we confirm the error, our payment provider refunds the overcharged amount, and the tax charged on it, to your original payment method, usually within 5 to 10 business days. If we find a billing error ourselves, we refund it without you having to ask.

You can cancel at any time from the Billing page in the console, or by emailing contact@deltallm.io. There is no cancellation fee. Your API keys stop working right away, and we make one final charge for the platform fee on usage from the start of the current billing period until you cancelled, plus any amount carried forward from earlier periods. If that final amount is less than $1, we waive it. Nothing is charged after that.

• The platform fee on usage that was correctly measured and priced under our Terms.
• Charges from your AI providers. They bill you directly under your own accounts, so contact the provider about those charges.

Email contact@deltallm.io from the address on your account with the date and amount of the charge, or the order number on your receipt, and what you think is wrong.

You have a 14-day right to withdraw from the contract after you sign up. By sending requests during that period, you ask us to start providing the Service right away. If you withdraw, by cancelling or by emailing us, you pay only the platform fee on usage before you withdrew.
