Postcard Log
A private postcard log 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.
Postcards are the slowest social network and the only one worth keeping records of. The Postcard Log tracks each card sent and received — the penpal or place, the direction, the date, and a few lines on what the front looked like, since the picture is half the point. For penpals, postcrossers, and anyone who still believes in stamps.

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 (Penpal / place, Direction, Date and What the front looked like) 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 postcard 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 keep track of postcards I have sent and received?
Every card gets an entry with the penpal or place, whether it was sent or received, the date, and a description of the front. Over time it becomes a paper correspondence, indexed.
Does this postcard tracker require the internet, unlike the postcards?
Pleasingly, no. It is a single HTML file that runs offline in your browser — no account, nothing leaves the page, and the file is yours forever. The log is as self-contained as the hobby.
Why record what the front of the postcard looked like?
Because the card itself goes in a shoebox or across the sea, and years later what you remember is the picture. A line or two — lighthouse at dusk, alarming cartoon goat — brings the whole card back.
