Terms of use

Using the site

reflexdojo is free to use, with no account and no purchase. You may use it for personal or commercial purposes. You may not attempt to disrupt it, submit automated results to the shared statistics, or scrape it at a volume that degrades it for other people.

Accuracy

Every effort is made to measure accurately, and the methodology page describes exactly how. Even so, results depend on your browser, your display and your input device, and they carry an uncertainty we can estimate but not eliminate. Treat them as a good measurement, not a laboratory one.

Not a medical or diagnostic tool

Nothing here diagnoses anything. Reaction time, memory span and typing speed are affected by sleep, medication, mood, illness and hardware. If a result worries you, that is a conversation for a clinician and not for a website.

No warranty

The site is provided as it is, without warranty of any kind. It may be unavailable, it may contain errors, and features may change or be removed.

Content

The text, code and design of this site belong to its author. Published benchmark figures drawn from other people’s datasets are attributed where they appear, and remain theirs.
