Measured on your machine.
Your keystroke timings are computed and stored on the device you type on. There is no cloud copy and no sync — the data physically can't leak from a server we don't keep.
Tactus is built to measure how you type without ever sending it anywhere. Everything the app records — every keystroke, every bigram, every millisecond — lives on your own machine. The only personal data we hold right now is the email you choose to leave for the beta list.

Tactus runs fully offline. It doesn't phone home, doesn't stream telemetry, and doesn't need an internet connection to measure, find, or drill your slow pairs.
There's no sign-up, no password, no profile. You don't hand us an identity to use the app — so there's nothing for us to lose, sell, or get subpoenaed for.
This site carries no third-party trackers, advertising scripts, or cross-site cookies. We don't build a profile of you as you read.
Everything the app measures about how you type is yours alone. We never receive it.
If — and only if — you join the beta list, we store the address you give us so we can write to you.
| What it is | Where it lives | Who can see it |
|---|---|---|
| Keystroke timings | on your device | Only you. It never reaches us — there's no server to send it to. |
| Drill history & progress | on your device | Only you. Delete the app and it's gone with it. |
| Beta-list email | our database | Us only, and only to send a launch note. Removed the moment you ask. |
| Hashed IP (signup only) | our database | Us only, for rate limiting and abuse prevention. We store a one-way hash — not your raw IP address — and never use it for profiling. |
| Site analytics | not collected | No one. We run no third-party analytics on this site. |
Write to us and we'll tell you exactly what's tied to your address — which, on the pre-launch site, is just the address itself.
Ask to come off the list and we delete your email — no “are you sure” loops, no retention window. Email us to be removed.
Because everything the app stores is local, you're always in control: clearing the app's data or uninstalling it removes every measurement permanently.
Privacy shouldn't take a lawyer to read. If anything here is unclear — or you'd like the long version when we ship — just ask.
