Undetectable AI Refund and Cancel Subscription and Why Credits Expire

Undetectable AI will stop charging you the moment you cancel, but it will not refund the period you already paid for, and your unused word credits expire immediately when the cancellation goes through. The money-back guarantee printed on the pricing page is narrower than it looks: the terms limit it to a refund of credits, only when a submission provably measures below a 75 percent threshold on a third-party checker, and only if you ask within 30 days of the incident. Two practical consequences follow. Cancel at the end of your billing month rather than the day you decide, and if you only need a break, ask to pause instead, an option their support documents but their pricing page never mentions.

All of the terms below were read first-party on September 8, 2026, on undetectable.ai/terms and on the subscription cancellation article in their own help center. Policies change, so check the dates against what you see today before you rely on any of it.

What the Undetectable AI refund policy actually says

There are two different documents here and they do not say the same thing, which is the root of most of the confusion around this question.

The pricing page carries a short, confident line about a money-back guarantee covering the cost of humanization. Read on its own, that sounds like a general satisfaction guarantee of the kind you get from a hosting company: unhappy, ask, get your money back.

The terms page is where the actual policy lives, and it is considerably tighter. It limits the remedy to a refund of credits rather than a blanket refund of what you paid, attaches a specific evidential condition to it, and puts a clock on the request: it must be made within 30 days of the incident. Note the wording there. The 30 days runs from the incident, not from your payment date, so the clock on a piece of work you ran in week one has already started even though the invoice is a month away.

None of this is unusual or improper. A conditional, evidence-based remedy is a reasonable way to run a guarantee on a product whose output quality is subjective. It is simply much narrower than the pricing page implies, and that gap is worth knowing before you count on it.

Does cancelling refund the current month?

No. The terms are explicit that cancellation stops future charges but does not refund prior billing periods unless the law requires it. So the day you cancel, you are not buying your way out of the month you are in. You have already paid for it.

That is standard for monthly SaaS and nothing to complain about on its own. It matters here because of what happens to your credits, which is where people actually lose money.

Credits expire on cancellation, and that costs people money

Their help center states it plainly: on cancelling, any remaining credits associated with the premium plan expire. Not at the end of the period you paid for. On cancellation.

Put those two rules next to each other and the trap is obvious. Cancelling does not refund the current month, and cancelling immediately destroys whatever allowance is left in it. Cancel on the 3rd of the month with 9,000 of your 10,000 words unused, and you have paid for the full month and kept none of it.

So the sequence that saves you money is simple, and it is the single most useful thing on this page:

1. Decide you are leaving, but do not cancel yet.
2. Use up the credits you have already paid for, or at least run through the work you were going to run.
3. Cancel a day or two before your renewal date, leaving enough margin for a support email to be actioned if you are cancelling by email rather than in the dashboard.

The only reason to break that order is if you no longer trust the product with your text at all, in which case getting out immediately is worth more than the credits. That is a judgment call, but make it deliberately rather than by accident.

Two routes to cancel an Undetectable AI subscription

There are two ways out, and which one applies depends on how you subscribed.

In the dashboard. Log in, open your profile icon, go to Settings, then Manage Subscription, and choose Cancel Plan in the billing section. This is the route most self-serve subscribers will have, and it is the faster of the two because nothing waits on a human.

By email. Their help center documents cancellation by writing to contact@undetectable.ai, and it asks for four specific things: the account email, your full name, the last four digits of the card the subscription is billed to, and your subscription details. Send all four in the first message. Cancellation requests that arrive missing the card digits or the account email turn into a round trip, and a round trip near your renewal date is how you get billed for another month.

If you use the email route, keep the sent message and any reply. That is your evidence of the date you asked, which is the thing that matters if a renewal charge lands afterwards and you need to dispute it.

The pause option that is not on the pricing page

This one is genuinely useful and almost nobody knows about it, because it appears in the help center rather than anywhere a prospective buyer would look. Instead of cancelling outright, you can ask to pause: temporarily suspend the premium subscription without being charged. You state the pause duration in the same email, and their support team sets it up.

For a lot of people that is the right answer rather than cancellation. Students who need a humanizer during term and not over the summer, freelancers between contracts, and anyone whose workload arrives in bursts are all paying twelve months for maybe five months of use. Pausing turns that into a seasonal cost.

It is also worth doing the arithmetic on your whole subscription stack while you are in there, because this is rarely the only tool quietly renewing. Most people underestimate their recurring software spend by a wide margin, and a read-only pass over what your SaaS subscriptions actually cost each month usually finds more than one line nobody has used since spring.

What a refund, a cancellation and a pause each actually do

One honest gap in that table: what happens to credits during a pause is not documented anywhere we could find. If you have a meaningful balance and you are choosing between pausing and cancelling, ask that question in the same email rather than assuming the balance survives.

What to do before you cancel

Three things, in order, and all of them take a few minutes.

Save your outputs. There is no export in this category as a rule, and once the subscription ends you should assume the account view goes with it. Anything you still need, copy out now.

Keep evidence if you might claim. The refund remedy is evidence-based and time-limited, so if you have a specific piece of work that did not come back as promised, capture the before and after text and the date while you still have access. Reconstructing that after you have cancelled is close to impossible, and the 30 day clock does not pause for you.

Check the renewal date, not the signup date. Annual plans in this category renew quietly, and the 50 percent annual discount makes the annual plan the one most people are on. Find the actual next charge date in your billing section before you decide when to act.

If you are leaving, what to look at next

Most people who search for this are not really asking a billing question. They are asking whether to keep paying for this category at all, and the answer usually depends on why the first purchase disappointed them.

If the problem was output quality on your particular kind of writing, the useful thing to know is that this is the single most divided product in the category. Its Trustpilot reviews split roughly half five star and 41 percent one star, which is a genuinely unusual shape and tells you the experience is inconsistent rather than uniformly poor. We went through that distribution, the pricing and the press claims in detail on our review of whether Undetectable AI is legit.

If the problem was cost, compare on cost per 1,000 words rather than headline price, because every plan here is a monthly word pool and the tiers are not proportional. The tier by tier arithmetic is on our Undetectable AI pricing breakdown, and the wider field, including where each rival genuinely beats us, is set out in the Undetectable AI alternatives comparison.

And whatever you move to, run the same test before you hand over a card: take a real paragraph of your own writing, not a sample, put it through, and read the two versions side by side. Did the meaning survive, is the specific claim that made the paragraph worth writing still there, and does it still sound like you. That test costs nothing and it predicts your satisfaction far better than any star rating, including the one on this page.
