Coffee Journal
A private coffee journal in one HTML file on your machine: no account, no cloud, no server to talk to.
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.
Somewhere between the fourth bag of beans and the third grinder setting, the cups all blur together. The Coffee Journal is where each brew gets a line of its own, so the morning you finally nail it, you can find your way back tomorrow.
Standing facts
- One HTML file. Opens in any modern browser, on any operating system.
- No account. No login, no sign-up, no e-mail wall.
- No cloud. Nothing leaves your browser: no server, no telemetry, no analytics.
- Yours forever. The file keeps working whether or not Offline.Ltd does.
- Ages with use. Entries you tend keep their bloom; the years travel with the file through every reforge.
In ten years
Whatever you put in 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 coffee journal 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 entries 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 Hobby tools →
Questions people ask
How do I keep track of coffee beans and brew settings?
You log each brew as an entry — the beans, the settings, what the cup was like, in your own words. It keeps the list; the tasting is still your job.
Does the Coffee Journal store my data online?
No. It's one HTML file running in your browser, offline, with no account and no server. Your brewing history stays on your machine and is yours for keeps.
Is this worth it if I just make one pot a day?
Especially then — one pot a day means one chance a day, and notes shorten the road. A week of honest entries teaches you more than a month of vague dissatisfaction.
