Investment Log
A private investment log in one HTML file on your machine: positions, costs, dates, and the reasoning you'll forget by next quarter.
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.
You bought the shares with conviction, and now you can't quite recall what you paid or why. The Investment Log keeps the plain facts — each position, its purchase price, its current value, and its type from stocks to property — so your portfolio is a list you keep, not a story you retell.

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 (Position, Purchase price, Current value and Type) 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 investment 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.
Questions people ask
How do I track my investments across different accounts?
One entry per position, wherever it lives: what it is, what you paid, what it's worth now, and its type — stocks, funds, bonds, crypto, property, or other. For the first time, the whole spread sits on one page.
Does this tool connect to my broker or bank?
No, and that's deliberate. It's a single HTML file running offline in your browser — no accounts linked, no credentials asked, nothing leaves the page. You type the values in yourself, and everything stays with you.
How is this different from my broker's app?
Your broker shows you what you hold with them; this holds everything — every account, plus the property and the odd crypto experiment. And it never turns red at you in real time, which your nerves may appreciate.
