One Swiss Knife in the exact shape of your life.

Language Learning

A private language learning in one HTML file on your machine: no account, no cloud, no server to talk to.

Live · runs in your browser · no network

This is not a screenshot. It's the real tool, running right here: go on, put something in it.

Forged into a knife, this tool ages with use: the blades you reach for wear soft, entries you tend keep their bloom, and the years travel with the file through every reforge.

Twenty minutes of Portuguese on Tuesday, a podcast on Thursday, then a week of nothing and the vague guilt that follows. The Language Learning log keeps the plain record: what you studied, which language, how many minutes, and the date. Seeing the minutes add up in black and white does more for consistency than any streak animation ever did.

Manual:

What it keeps

Standing facts

In ten years

Whatever you put in (What I studied, Language, Minutes and Date) stays inside the file itself. There is no account to lapse, no plan to be sunset, no migration e-mail with a deadline in it. A decade of language learning entries is a decade of your own handwriting, kept in a document you can back up like any other.

If Offline.Ltd closes tomorrow, nothing on your machine notices. That isn't a marketing promise; it's simply what a file is.

Getting your data out

Export to CSV from inside the tool and open it in anything: a spreadsheet, another app, a text editor. Or keep the HTML file: it is plain, readable, and inspectable; you can open it in a text editor and see your own rows sitting there. No export queue, no "we'll e-mail you a link within 48 hours", no format that only one vendor can read.

Copy the file to a USB stick, a NAS, a folder your devices already sync. It runs on Windows, macOS, Linux, Android and iOS, online or off, because a browser is the only thing it ever needed.

Who else sees this

Nobody. Your What I studied, Language, Minutes and Date never leave the file on your own disk. There is no account, no telemetry, no analytics, and no code in the file that opens a network connection, pull the cable and watch it carry on working. How privacy works across the Knowledge tools →

Questions people ask

01

How do I track my daily language study time?

After each session, add a row: what you studied, the language, the minutes, the date. That is the whole ritual — thirty seconds of bookkeeping that makes the habit visible.

02

Can I log more than one language in the same tracker?

Yes — the language is just a field on each entry, so your French and your stubborn attempt at Japanese live side by side in one list.

03

Does this language tracker need an internet connection or an app store?

Neither. It is one HTML file that runs offline in any browser, with no account and no download from a store. Your study log never leaves the page, and there is a live demo right here — go on, try it, it is the real thing.
