Cycle Tracker
A private cycle tracker in one HTML file on your machine: dates and symptoms kept where no data broker can reach them.
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.
Cycle apps have developed a reputation for being nosy, which is a strange quality in something so personal. This Cycle Tracker is the opposite: a plain private log of start date, flow — Light, Medium or Heavy — and a space for symptoms and notes. It sits on your own machine and tells no one anything.

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 (Start date, Flow and Symptoms & 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 cycle tracker 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
Is there a period tracker that does not collect or sell my data?
This one collects nothing because it has nowhere to send it. It runs offline in your browser with no account and no server; your cycle history stays inside one HTML file that is yours alone, forever.
How do I track my cycle with this tool?
When a cycle starts, add an entry with the start date, pick the flow, and note any symptoms. Over the months the list becomes your own record of timing and patterns, written by the only person qualified to write it.
Can I record symptoms like cramps or mood changes too?
Yes — each entry has a symptoms and notes field for exactly that, in your own words rather than someone else's checkbox taxonomy.
