Knowtient has no accounts, no logins, and no advertising. It never asks for your name, your email address, or anything else about you, and there is nothing to sign up for. This page covers the small amount that is collected anyway, and what happens to it.
One number.
When you complete a round, the game sends your average deviation — a single figure between 0 and 100, rounded to one decimal place — to its database. The row it creates holds that number, an automatically assigned row number, and the time it arrived. That is the entire record:
id a sequential row number
avg_off your average deviation, e.g. 14.3
played_at the moment the row was written
No IP address, no device details, no cookie, no session identifier, no name for the round, and nothing that links that row to you or to any other row. Two rounds played by the same person are indistinguishable from two rounds played by two strangers.
That number exists for one reason: so the next player can be told where their score falls against everyone else's. It is the only thing the percentile rank is calculated from. Rounds you abandon part-way are never sent.
To stop an automated script from flooding the score table, the site checks how many requests have arrived from a given source in the last minute. To do that it takes the incoming IP address, hashes it, keeps only the first 16 characters of the hash, and holds that in memory for sixty seconds. The address itself is never written down, never stored on disk, and never reaches the database. After the minute passes, the hash is gone.
The site uses Vercel Web Analytics for basic traffic counts. It sets no cookies and does not track you across other websites. For each page view it records the time, the page address, the referring site, an approximate location derived from the request, and the general type of browser, operating system and device.
Visitors are counted using a hash generated from the request rather than a stored identifier, and Vercel discards it after 24 hours. Vercel's own description of what it collects is published here.
us-east-2 (Ohio, United States).Your browser never talks to the database directly and never holds a database credential. Scores go through this site's own API, which is the only thing that can write to it.
Score rows are kept indefinitely. The percentile rank is more useful the more rounds it is drawn from, and since a row is a bare number with no person attached, keeping it costs no one any privacy.
The site also runs an automated hourly check that the database is still reachable and still writable. It keeps a single row that records when the last successful check happened and how many have succeeded in total. It contains no visitor data of any kind.
If what is collected changes, this page changes with it and the date at the top moves.
