Sourdough Log
A private sourdough 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.
Three weeks ago you baked the best loaf of your life, and now you can't remember whether it was 72% hydration or 78%. The Sourdough Log keeps each bake on record — the loaf, the hydration, the date, and a notes box for feed schedule and crumb — so the good ones stop being accidents.
What it keeps
- Bake / loafshort text
- Hydration %number
- Datedate
- Feed schedule, crumb, notesnotes
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 (Bake / loaf, Hydration %, Date, Feed schedule, crumb and notes) 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 sourdough 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 Bake / loaf, Hydration %, Date, Feed schedule, crumb and notes 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 my sourdough bakes and hydration?
One entry per bake: name the loaf, note the hydration percentage and date, and write whatever mattered — how you fed the starter, how the crumb turned out, what you'd change. Next time, you look it up instead of guessing.
Can I use a baking log without an account or an app subscription?
Yes. This is a single HTML file that runs offline in your browser. No account, no cloud, no monthly fee — your bakes never leave the page, and the file is yours for good.
Is this for beginners or experienced bakers?
Both, honestly. Beginners use it to notice patterns; old hands use it to remember which tweak produced which crumb. The demo on this page is the actual tool, so you can log an imaginary loaf right now.
