One Swiss Knife in the exact shape of your life.

Birding Log

A private birding log 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.

A goldcrest at the back fence on a Tuesday is a small event, but it's your small event, and it deserves writing down. The Birding Log keeps your sightings plainly — species, where, and the date — a life list that grows one honest line at a time.

Manual:

What it keeps

Standing facts

In ten years

Whatever you put in (Species, Where 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 birding log 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 Species, Where 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 Hobby tools →

Questions people ask

01

What's a simple way to keep a bird sighting list?

Three things per sighting: the species, where you saw it, and when. That's how birders have done it for a century in notebooks; this is the same notebook, just harder to leave on a train.

02

Does the Birding Log work without internet in the field?

Yes. It's a single HTML file that runs in your browser, fully offline — hedgerows rarely have wifi. Nothing you record leaves the page, and there's no account to make.

03

Is this a bird identification app?

No — it identifies nothing and won't argue with you about warblers. It keeps the list of what you saw, where and when, and leaves the identifying to you and your field guide.
