Weather Diary

A private weather diary 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.

Long before satellites, people kept weather in notebooks — and the habit still beats memory, which is convinced every summer was better. The Weather Diary keeps your patch's record: the date, the sky — from Clear through Half-hearted sun to Dutch grey and worse — the pressure, what the knee says, and notes. In a year you will have your own climate, in your own words.

What it keeps

Standing facts

In ten years

Whatever you put in (Date, Sky, Pressure (hPa) and What the knee says) 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 weather diary 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 Date, Sky, Pressure (hPa) and What the knee says 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 Homestead tools →

Questions people ask

01

Why keep a personal weather diary when forecasts exist?

Forecasts predict; a diary remembers. Your own record tells you when the last frost really came, how wet this spring was against the last one, and whether the knee's forecasting record deserves its reputation. Gardeners and countryfolk have sworn by the practice for centuries.

02

What is the pressure field for?

Barometric pressure is the old honest signal — falling fast means weather coming, rising means it clearing. Log it daily and you can watch the systems move through your own numbers, and check them against what the knee claimed.

03

Where does my weather data go — is it shared with some service?

Nowhere and no. The diary runs offline in your browser, needs no account, and keeps everything inside one HTML file that is yours forever. Your weather stays as local as weather ought to be.
