How do I delete my account?

In the app, open Settings (the gear icon) and tap Delete account. This permanently deletes your account and everything in it: your plan, meals, weigh-ins and favorites. It can't be undone.

I got a new phone. How do I get my data back?

Install Size Up, tap "Already have an account? Sign in" on the first screen, and sign in with the same email. Your plan, meals, weigh-ins and favorites download automatically.

How accurate are the calorie and macro numbers?

They're AI estimates, and like any estimate they can be off, especially for mixed dishes or photos where the portion is hard to judge. If a number looks off, you can enter your own values on the Log screen instead.

How do I change or turn off the daily reminder?

Open Settings and use the Daily reminder switch. You can also change the time there. It only reminds you on days you haven't logged anything.

Is Size Up medical advice?

No. Size Up is a general fitness and nutrition tool. If you have a medical condition, are pregnant, or have a history of disordered eating, talk to a doctor before changing how you eat.
