There is no support desk behind this page — just the people who build TailsNow. Say which tool you were on and what you expected, and you will get a real answer.
TailsNow is a coin flip, so the messages that reach us tend to be about settling a decision fairly or about a figure that did not look right. Both are worth sending.
The address to use is support@tailsnow.com; we generally reply within one or two business days.
Details that help us
- Which calculator you used, or a copy of its address.
- A rough version of the coin toss itself — we only need enough of it to redo the sum.
- The answer you got next to the answer you anticipated.
- Device, browser and anything else that may have interfered.
If your question is about settling a decision fairly, say so in the first line — it helps us find the right answer for TailsNow faster.
Reporting an error in a result
Because the method is written down rather than hidden, an error report is easy to act on. TailsNow works on the principle that it draws each flip from the browser's cryptographically secure random source rather than a pseudo-random seed, so the sequence is not predictable from earlier flips, and it reports the running ratio of heads to tails so a fair coin visibly converges, so when a figure disagrees with your own working, one of the two has slipped. Send both and we will find out which.
