The Strong Game keeps everything you log on your own device. That's deliberate, and it's the right call — but it comes with one responsibility that takes about ten seconds a week.
There's no account, no login, and no server. When you log a meal or a workout, that entry is written into your browser's own storage on the phone or computer in front of you. It never travels anywhere.
That means nobody can see your data — not us, not anyone. If you share this tool with your sister, you each get your own copy on your own phone. Nothing mixes. There's no database of women's weights and symptoms sitting somewhere waiting to be breached, because there's no database at all.
It also means something less comfortable.
If your data disappears, there is no support desk that can bring it back. We don't have a copy. The only copy that can exist is the one you make.
Browser storage is durable but not permanent. The usual causes, roughly in order of how often they actually happen:
None of these are exotic. Most people hit at least one over sixteen weeks.
Open Setup, tap Export, once a week. That's the whole thing.
You'll get a file called something like strong-game-2026-09-14.json. On an iPhone it lands in Files, wherever you choose to put it. It holds everything: every day you've logged, your targets, your measurements, your scans, your custom foods.
The habits that survive are the ones bolted to an existing habit. If you do a weekly scan, export straight afterwards — you're already in the app, already thinking about the week. Sunday works well for most people.
The tracker will also nudge you. If you've logged several days and haven't backed up in a week, a note appears at the top of the Today screen with an Export button in it. You can snooze it, but the count keeps rising, and it exists precisely so you're not the person who finds out in week nine.
A backup that lives only on the device you're backing up isn't much of a backup. Save it into iCloud Drive, Google Drive, or Dropbox — anywhere synced. Or email it to yourself. Any of those survives a lost phone.
Keep the last few rather than overwriting. They're tiny.
Restoring takes three steps:
It'll tell you how many days it found and ask you to confirm before anything is written. Your targets, rituals, supplements, custom foods, and full history all come back.
Browser storage is tied to the exact web address it was created at. If you open the tracker from a file saved on your phone and later switch to the hosted version, your entries won't follow — they'll look like they disappeared.
Decide how you're going to open it, then use only that. If you're on an iPhone, open the page in Safari, tap Share, and choose Add to Home Screen. Then use that icon and nothing else. It runs full-screen like an app, and it keeps your storage in one predictable place.
Neither one loads anything from a third party. No analytics, no tracking pixels, no fonts fetched from someone else's server, no requests that would tell an outside company you were here. Once the page has loaded, it works with no internet connection at all.
That's a deliberate choice rather than an oversight. A tool for tracking symptoms, weight, and hormonal changes is not a place to leak a visitor list.
Send this page with it. The tool is easy to pick up and the export habit is the only part that isn't obvious — and the people who lose eight weeks of work are, understandably, the people who don't come back.
Worth saying plainly to whoever you send it to: their data is theirs, on their phone, invisible to you and to us. And so is the responsibility for keeping it.
