Support
We are a small team and we read every message.
Contact ussupport@sigmatools.io
Email us with your question, your device (iPhone / Android), and a screenshot if something looks wrong. We typically reply within two business days.
Account & sign-in
- Trouble signing in? Atlas works fully offline with no account - your training is saved on your device. Signing in only adds cloud backup + cross-device sync (a Premium feature). If sign-in fails, email us the email address you used and we will sort it out.
- Lost your data after reinstalling? Free accounts are stored on-device, so deleting the app removes local data. Sign in with Premium to keep an encrypted cloud backup that restores automatically on a new device.
Your data & privacy
- Atlas is local-first: your workouts live on your device unless you turn on Premium cloud sync. See our Privacy Policy for exactly what we collect and why.
- Delete your account or data. You can erase everything yourself from Profile → Settings, or follow the steps on our account deletion page. The deletion is permanent.
Training & safety
Atlas's suggestions (Smart Coach, projected 1RM, load / rep hints) are informational estimates, not medical advice. Before a new program or a new max, read our Health & Fitness Disclaimer. If you feel sharp pain, dizziness, or chest pain, stop and seek medical attention.
