Why log
Why strength athletes keep set logs.
1RM is one number; e1RM trends and Wilks tier are the working signals.
Wilks-banner classifies your total.
SBD total / bodyweight ratio: Novice (5×) / Intermediate (8×) / Advanced (11×) / Elite (14×) / World class. The line every lifter knows.
e1RM per lift via Brzycki formula.
Working number for daily lifts, even when you didn't max out. weight × (1 + reps/30). The number that matters week-to-week.
RPE + RIR per set capture intent.
Some weeks grind, some weeks float. The trend over 30 days shows whether you're peaking or accumulating fatigue.
PR flag triggers the celebration.
Tick PR on a set; lifetime PRs tier card increments. Quiet milestones.

Your numbers are yours.
Not a coach's KPI.
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.

Every view, light and dark.
A look at every screen across both themes — your tracker, populated.
Questions
Real answers, no fine print.
Olympic lifts / accessory tracking?+
Yes — accessory type covers everything beyond the big four. Snatch + clean & jerk could each be added as separate lifts.
Auto rest timer?+
No — use your phone timer. The log is for sets, weights, reps, RPE — the data that matters across years.
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.
A logbook for the platform.
We'll personalise a copy and email you a private link. Bookmark it, install it as an app, log Wednesday's bench.
