REFUNDS · LAST UPDATED 2026-05-21

I DON'T POST A REFUND WINDOW. EMAIL ME ANYWAY.

If you bought Pro and something went wrong, please get in touch. Here's how that usually goes.

01THE THIRTY-SECOND VERSION

FIVE THINGS, IN ORDER

  1. Try the free version first. Three CSV uploads with no account, no card. That's the risk-reducer. If the free version doesn't work for your car, don't buy Pro.
  2. If you did buy Pro and it's broken for you, email me. [email protected] with the Stripe receipt and what went wrong.
  3. I refund honest cases. "Free worked, Pro doesn't unlock." "Math returns nonsense for my car." "Bought twice by accident." All refundable.
  4. I don't refund buyer's remorse on a working product. "I changed my mind a month in." "I only used it once." That's not a quality issue.
  5. Card disputes are a last resort. They cost me $15 plus the refund. Email me first. I move fast.

02WHY THERE'S NO POSTED WINDOW

A posted refund window can be difficult to honour fairly case-by-case. For a working product at $19 with an unbounded download window, a fixed window also tends to attract a familiar pattern: buy, use the product heavily inside the window, then refund.

For those reasons, this page doesn't state one in advance, and each request is handled by email instead. The trade-off is that this reads less reassuring than a posted window. The upside is that real quality problems usually get handled faster, because each email is treated as its own case.

FOR BUYERS

The free version is the trial. Three uploads with no account, no card. If the free version works for your car, Pro will too. If it doesn't, Pro won't be different. Try it before you buy it.

03WHAT I WILL REFUND

Situations that usually get refunded, no debate needed. Email any of these and a refund typically goes through inside one business day.

UNLOCK FAILED You paid Stripe, the receipt is in your inbox, but the Pro token never landed in your browser and never will. Full refund. SAME DAY
BROKEN FOR YOUR CAR The free version produced sane numbers, then you bought Pro and the Pro features (save runs, overlay compare, dashboard) don't work for your trim. Full refund + a bug report. SAME DAY
MATH IS WRONG The result is implausible for your car (off by >25% from a real chassis dyno you have a printout of). Send me the CSV + the dyno sheet. Full refund, even if I fix the model and re-issue the number. ~3 DAYS
DOUBLE-CHARGED Stripe charged you twice. You only meant to buy once. Refund the duplicate immediately. SAME DAY
CHILD / SHARED CARD Someone else used your card. You didn't authorize the purchase. Full refund. No questions asked. SAME DAY
REASONABLE TIMING, LIGHT USE You bought Pro, used it once or twice, decided it isn't for you, and email me before significant time has passed. Generally refunded. I'd rather refund and move on than argue over $19. No specific day count promised; reasonable timing is judged by use, not by a clock. NO DEBATE

04WHAT I WON'T REFUND

The other side. None of these are personal, and there's no template I'm checking against. They're patterns that tend to show the product was working as intended.

×
Heavy use, then refund.Saved 40 runs, exported 12 share cards, then asked for your money back six months in. At that point the product clearly worked for you.
×
"It feels different than I expected."The free version showed you what the numbers look like. Pro adds saving and overlaying. Nothing surprises a Pro user about the math.
×
"My friend told me he got higher numbers."Different cars, different runs, different ambient conditions. The model is consistent; the inputs vary.
×
"I didn't know it was an estimate."Every page says "not a chassis dyno". Every share card has ROAD-LOAD MODEL in the foot. The methodology page explains the math.
×
Long after purchase, with no quality issue.If it's been months and the product worked the whole time, that's not a refund situation.
×
Chargeback first, then talk.If you skip email and go straight to a card dispute, that costs me the dispute fee even if I refund. Email is faster for both of us.

05HOW TO ASK

One email. Subject line REFUND. Three things in the body. That's the whole process.

@

EMAIL

[email protected]

SUBJECT: REFUND · BODY: RECEIPT + WHAT BROKE + WHEN

1 · RECEIPT Forward the Stripe receipt or paste the charge ID (ch_... or pi_...). I look up the exact charge. REQUIRED
2 · WHAT BROKE One or two sentences. "Unlock never landed." "Saved runs show empty after a refresh." "The number for my NC2 was 84 WHP, dyno says 134." REQUIRED
3 · WHEN When you bought it, when you noticed the issue. Helps me find related bug reports. REQUIRED
+ CSV (OPTIONAL) If the math is the issue, attach the CSV. I run it locally and figure out what the model did. Most "math is wrong" cases are actually a CSV-quality issue I can show you. HELPFUL

I reply inside one business day, usually the same day. Refunds land in 5-10 business days depending on your bank. There is no form. There is no ticketing system. It's just me at [email protected].

06CARD DISPUTES & CHARGEBACKS

A chargeback costs me $15 in Stripe fees on top of the refund. Please email me first. I will refund faster than your card issuer will.

IF YOU'VE ALREADY

filed a chargeback, that's fine. I respond to the bank with "customer didn't email first; refund granted" and move on. Email is faster, cheaper, and saves us both the back-and-forth.
