Subscriptions
How do I cancel?
Open the Settings app on your iPhone, tap your name, then Subscriptions, and choose LeanMaxx. Cancel at least 24 hours before your renewal date to avoid the next charge. Deleting the app doesn't cancel your subscription.
I paid but the app still shows the paywall
Tap Restore on the paywall. Make sure you're signed in with the same Apple ID you subscribed with. If it still doesn't unlock, email us.
Can I get a refund?
Purchases go through Apple, so refunds are handled by Apple. Request one at reportaproblem.apple.com.
New phone?
LeanMaxx doesn't use accounts. Install the app, then tap Restore to unlock your subscription. Your logs and photos live on your old phone, so use Profile → Settings → Your data → Export my data before you switch.
Scans and projections
Tips for a better scan
- Stand back far enough that your whole torso fits the camera guide, shirtless, in even front lighting.
- Use the same spot, time of day and pose every week so the trend is comparable.
- Log your weight — it narrows your body-fat range over time.
My projection didn't finish
Projections take up to a couple of minutes, and there's a daily limit. If the app says you've hit the limit, try again tomorrow. If a photo is rejected, retake it with your full torso in frame and good light.
Why is my body fat a range?
No photo can measure body fat precisely, so LeanMaxx shows an honest range. It tightens as you take weekly scans and log your weight.
Your data
How do I delete my data?
In the app, go to Profile → Settings → Your data → Delete my data. This erases everything on your phone and deletes your photos, projections and results from our server. LeanMaxx has no accounts, so there's no account to close beyond this. If you've already deleted the app, email us and we'll help.
How do I get a copy of my data?
Profile → Settings → Your data → Export my data.
Apple Health steps aren't showing
Open the Health app → Sharing → Apps → LeanMaxx and make sure Steps is turned on.
