One File · Powerful health tracker
Quietly log
every week.
A pregnancy log in one HTML file. Weeks, weights, moods, kicks, scans — built privacy-first for the parent who doesn't want any of it on a server, in a wellness platform's training set, or in an insurance algorithm.
One payment · Yours forever · 14-day refund

Loads once, never needs the internet again. On a plane, in a basement, in a foreign hotel.
Every entry, every chart — stored locally. We never see it. We can't.
No subscription. No upgrades. No re-up next year. One file, yours.
Why local
Why pregnancy data shouldn't live on a server.
Pregnancy is the most personal, most regulated, most surveilled data category in modern apps. The local-first promise matters here most.
Daily logging beats dramatic check-ins.
Two minutes a day for forty weeks is more useful than a panicked review at thirty-six. The streak calendar gently rewards the cadence.
Kick counts are reassurance.
Most clinicians suggest counting movements after week 28. The kick session is twenty seconds to start, twenty seconds to stop, and the tier-card holds the day's total without drama.
Stealth mode for shared phones.
Blur week, weight, symptoms behind a tap. Useful in cafés, useful with kids, useful if you're not telling work yet.
It works after the company doesn't.
If OneFileClub disappears tomorrow your file keeps working. No 'sunset notice', no migration deadline.

The promise
Your pregnancy is no one's marketing list.
Especially not a server's.
Offline, always
Open it once, never need the internet again. The file holds the whole app.
Local-first storage
Every entry stored in your browser, on your device. No server sync. No leaks. Nothing to breach.
One payment, forever
No subscription, no upgrade tier, no nag. If we shut down OneFileClub tomorrow, your file keeps working.
Data does not sync automatically between phone and desktop
This is a local-first app — everything stays on the device you logged it on. To use it on both phone and desktop, use the built-in JSON or CSV export on one device and import on the other when you want to keep them in step.
Every view, light and dark.
A look at every screen across both themes — your tracker, populated.
Questions
Real answers, no fine print.
Is this medical advice?+
No. The log captures your data and surfaces patterns; if anything concerns you, ring the midwife or go to the assessment unit. It's a tracker, not a clinician.
Can I share with the midwife?+
Yes. Export to CSV, print, or just hand them the phone. Most find the kick-count timeline and the symptom history immediately useful.
Where is my data stored?+
Locally, in your browser, on your device. Nothing is sent to OneFileClub or anyone else — there is no account, no cloud sync, no analytics.
Does it work offline?+
Yes. Once your personalised copy loads the first time, the entire tracker runs from a single HTML file. Airplane mode is fine.
What does 'personalised copy' mean?+
When you buy, OneFileClub stamps a private copy with your licence and deploys it to a unique URL just for you. You bookmark it, install it as an app, or save the file — and the file is yours, even if OneFileClub disappears tomorrow.
What is your refund policy?+
14 days, no questions asked. Email us, we'll process it and disable your private URL.
One payment.
Forty quiet weeks of logging.
We'll personalise a copy and email you a private link. Bookmark it, install it as an app, log today before bed.
