How refunds work

The promise is specific, and this page states the mechanism that is actually implemented — not a paraphrase of the marketing.

What you are charged for, and when

You are charged for the work, not the result. The charge lands the moment PIDSnap issues its first instruction to change a value — which constant, and the exact value to type. Everything before that, including the baseline step, costs nothing.

What triggers a refund

A refund is owed when PIDSnap's own result is that tuning is not what is wrong with the loop: a mechanical trend signature — stiction, backlash, a saturated output — or a loop that is safety-related. These are PIDSnap's conclusions, reached from the trend signature or the loop profile, so they cannot be manufactured by withholding a good photograph.

The iteration window

Inside the first 2 iterations, a mechanical or safety result is refunded automatically — the baseline trend, then the first response trend, and stiction is already unmistakable. You do not have to ask.

Past 2 iterations, the refund is not automatic. By then the session has issued real instructions, and an automatic refund however long it ran would be an open tab. The refund is still yours in full — it is claimed with a button on the session page, and the claim is honoured.

What you keep either way

The report, the analysis, and the record of every value that was tried. The refund returns the money; it does not take back what you learned.
