Account

An account is what makes you “you” in Sparta. It’s how the app knows who’s logging workouts, which groups you belong to and which devices to sync to. You sign in once, then everything follows you.

You sign in with Continue with Google. Your password stays with Google. Sparta never sees it and never stores one of its own.

What an account does

Your account holds:

• Your workout templates, with their default sets, weights and rest times.
• Your history: every session, run, sport and check-in you’ve ever logged.
• Your custom exercises, available in every picker.
• Your group memberships and your standing in each one.
• Your streaks and your trophy record across past months.

If you sign in on a new phone, all of it shows up the next time the app finishes syncing. Nothing is tied to a specific device.

Backup and multi-device sync

You don’t have to think about backups. As soon as a workout finishes or you log a check-in, the entry uploads. Anywhere else you’re signed in picks it up.

A few things to know:

• Edits sync, deletes sync. If you delete a workout on your phone, it’s gone from your tablet too.
• Unfinished sessions stay private to one device. A session you’re still logging only leaves your phone once you tap Finish. If you start a session on your phone, you can’t pick it up mid-set on your tablet.
• Offline-first. You can log workouts without a connection. They upload the next time you’re online.

Groups

Your account is the unit that joins groups. One account, many groups, each with its own leaderboard, ranking history and streak tracking. See groups for the full breakdown.

You can be in multiple groups at the same time. Activity counts for every group you’re in. There’s no separate per-group history.

Connected services

Sparta can pull in workouts you record outside the app. Connect once and they show up in your history automatically.

• Apple Health on iPhone. Reads runs, rides, sports and other workouts saved by any app that writes to it (Strava, Nike Run Club, Apple Fitness, and more).
• Health Connect on Android. Same idea: reads workouts saved by Samsung Health, Strava, Fitbit, Garmin Connect and so on.

See the integrations guide for step-by-step setup.

Connected services are read-only. Sparta doesn’t push your Sparta sessions back into Apple Health or Health Connect.

Privacy

The full breakdown is in the privacy policy. The short version:

• Only people in groups you’re in can see your activity.
• We don’t sell data, run ads or share with third parties beyond the services needed to run the app.
• We don’t ask for medical information.

Deleting your account

You can delete your account from inside the app: Settings → Account → Delete account. This removes your data from Sparta’s servers. Workouts saved locally on your phone stay on your phone until you uninstall.

If you’d rather email to delete, see Account Deletion for the email-based option.
