Symptom Diary
A private symptom diary in one HTML file on your machine: when it started, how bad, what helped, and no one else asking.
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.
The doctor asks how long the headaches have been happening, and suddenly your memory produces nothing but fog. The Symptom Diary keeps the record your future self will thank you for: the symptom, its severity from 1 to 10, the date, and a space for triggers and notes. Patterns hide in weeks; a written list is how you catch them.

- Symptomshort text
- Severity 1-10number
- Datedate

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 (Symptom, Severity 1-10, Date and Triggers & 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 symptom 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.
Questions people ask
How do I track symptoms to show my doctor?
Log each occurrence with a severity score and the date, and jot suspected triggers in the notes. When the appointment comes, you bring dates and numbers instead of a shrug — doctors visibly relax at this.
Is my health data private in this symptom tracker?
Entirely. Nothing is uploaded anywhere — the diary runs offline in your browser, with no account, and lives in one HTML file on your own machine. Your symptoms are between you and the page.
What counts as a symptom worth logging?
Anything recurring you want to understand: headaches, flare-ups, dizzy spells, a rash that comes and goes. If you have ever said it happens sometimes, it is a candidate for the list.
