How to Backup and Restore Workout Data (JSON/CSV Guide)

No account doesn't mean no backup. It just means nobody's doing it for you in the background. You export a file, you put it somewhere safe, and that file is yours - not a sync job tied to a login you might forget.

Most people only think about this after a phone dies or gets wiped. By then it's either "glad I exported last month" or "there goes six months of logs." Thirty seconds now beats that conversation later.

Why file-based backup is worth setting up once

Cloud sync feels effortless until it isn't. The company changes policy, shuts down, or you lose access to the account. A JSON file sitting in your own Drive doesn't care about any of that. It opens the same way in five years whether the app still exists or not.

That's the real trade: automatic sync is convenient; a file you own is durable. Both are valid. The mistake is assuming backup exists just because you created an account somewhere.

Backing up Stay Fit's data

Head to Settings → Storage & Data.

• Export Backup (JSON) - full snapshot: routines, logged workouts, measurements, photo references. This is what you want if you might need to restore on a new phone.
• Export Data (CSV) - flat, spreadsheet-friendly history. Great for reading or archiving, but not built for a full restore.

Either option opens the system share sheet. Send it to Google Drive, Files, email yourself - wherever you already keep important stuff. No account on Stay Fit's end; the export is just a file.

How often to actually do this

Monthly works fine if you train casually and wouldn't lose your mind over a few weeks of history.

Weekly makes sense if you're mid-program, chasing a PR, or would genuinely be annoyed losing the last handful of sessions. The export takes about thirty seconds.

Restoring onto a new device

Install Stay Fit on the new phone, then Settings → Storage & Data → Import Backup and pick your saved JSON file.

Keep the JSON specifically for restores. CSV is for looking at your numbers, not reimporting them.

What you get that account-based backup doesn't

An account-tied backup lives on someone else's servers under someone else's terms. A file in your Drive answers to you. If Stay Fit disappeared tomorrow, your export would still open. That's not paranoia - it's just how file ownership works, and it's worth knowing the difference before you need it.
