We read everything that arrives here. PctZen is a small project, so a message that says which tool you were using and what you expected gets a useful answer fastest.
PctZen is a percentage calculator, so the messages that reach us tend to be about working out a sale price or about a figure that did not look right. Both are worth sending.

Details that help us
- Which calculator you used, or a copy of its address.
- Your inputs, which for this tool means the numbers you enter; exactness is not needed.
- The answer you got next to the answer you anticipated.
- Device, browser and anything else that may have interfered.
Messages about checking a percentage change between two figures are common here, and a short description of your case is usually enough for a useful reply.
If a result looks wrong
Because the method is written down rather than hidden, an error report is easy to act on. PctZen works on the principle that it picks the right rearrangement of the percentage relationship for the question you ask — part over whole, or the difference over the original — so the same tool covers a markup and a discount without the sign confusion, so when a figure disagrees with your own working, one of the two has slipped. Send both and we will find out which.
What happens to your message
We use what you send for a single purpose: answering you. It is not passed on, not added to a list, and not used for anything else — the privacy policy has the specifics.
