Privacy#
The trainer keeps your practice — ratings, drill results, solve times — because that is what it is for. This page is about the other thing an operator can switch on: traffic analysis, which counts how the site is used.
Whether it is on depends on who runs the instance. A local install has it off, and off means nothing is sent anywhere.
What is collected, when it is on#
The server reports to the operator's own Matomo installation:
- Which pages are visited, by name — "the OLL list", "the case page for OLL 27", "a docs page".
- What you do: signing in, rating a case, starting and finishing a drill, timing a solve (with the time), opening a case, switching the library between List, Radar and Globe, and what you search the library for, with how many cases matched.
- Your browser and language, as your browser announces them, and the page you came from — without its query string.
- Your network, not your address. The last part of your IP address is removed before it leaves the app (the last of four numbers for IPv4, the last 80 bits for IPv6).
If you are signed in, your visits are linked by a pseudonym: a code derived from your account that stays the same between visits but cannot be turned back into your name, email or account.
What is never collected#
- Your name, email address or account id.
- The contents of forms, or the query string of any address.
- Anything from a cookie set for tracking — there is none.
- Anything at all from crawlers and automated health checks.
No third-party script is loaded for this: the reporting is done by the server, plus a small script from the trainer itself for the two things only your browser sees (the List/Radar/Globe switch and when you've finished typing a search).
Opting out#
Turn on Do Not Track or Global Privacy Control in your browser. The trainer then sends nothing about your visits — not even the small reporting script is put in the page. Your practice data is unaffected: it is not traffic analysis, it is the thing you came for.
How long it is kept#
Raw visit data is deleted after 180 days. Aggregated reports ("how many visits last month") are kept, and contain no individual visits.
The server's own log#
Separately from traffic analysis, the server writes one log line per request for operating it: the same truncated address, the page without its query string, the browser, and — if you are signed in — the same pseudonym. It never contains a name, email or form contents.
