Terms of service

Plain words about using FitBest and paying for it, and what you can count on. Last updated November 4, 2026.

Who runs FitBest

FitBest is run by Star Seed Enterprises, in Brazil. These terms are an agreement between you and Star Seed Enterprises; by using FitBest, on this website or in the phone apps, you accept them. On this website, plans are sold by Star Seed Enterprises through Stripe. In the phone apps, Google Play and the App Store sell them for us, under their own terms as well as these. On iPhone, Apple's Standard License Agreement also applies.

Not medical advice

FitBest estimates calories and macros from photos and descriptions, and suggests targets from the details you give. The estimates can be wrong, and FitBest is not a medical device and not a substitute for a doctor or a dietitian. Talk to one before changing how you eat if you are pregnant, have a medical condition, or have or had an eating disorder, and don't rely on FitBest for allergies.

Your account

You must be 18 or older to use FitBest. An account is for one person. You sign in with links sent to your email, so keep that email safe: whoever can read it can sign in as you.

What you log

Your photos, meals, workouts and weights stay yours. You let us store and process them only to run FitBest for you, as the Privacy policy explains, and only log photos you have the right to use. The drawings FitBest makes of dishes are shared by everyone who logs that dish.

Using FitBest fairly

Don't use FitBest to break the law, upload anything illegal or harmful, try to reach other people's data, overload or attack the service, or copy it with automated tools.

The plans

FitBest has a free plan: you can add 2 meals a day, and delete meals but not change them. A plan unlocks everything (every meal, edits and Fix with AI) for $2 a week, $5 a month or $30 a year. Prices include tax where we collect it; the stores show them in your currency.

The free weeks

Every new account starts with a free week, with no card. After it, you can try one more week free with a card. That second week is offered once per person, and it becomes the plan you chose unless you cancel before it ends.

Renewing and cancelling

A plan renews each week, month or year until you cancel it. Cancel in Google Play or the App Store if you bought it there, or in Profile, then Manage or cancel, if you bought it here. You keep everything until the end of the period you paid for.

Refunds

You can ask for a refund within 14 days of a charge. For plans bought here, write to support@fitbest.app and we refund it through Stripe. For plans bought in Google Play or the App Store, ask them: they handle refunds with their own process.

Early members

Accounts made before plans existed are early members: everything stays unlocked, free forever, with nothing to buy.

Your data

What FitBest keeps and why is in the Privacy policy.

Ending

You can delete your account at any time, in Profile; the Delete your account page explains how. We may suspend an account that breaks these terms. If we ever stop offering FitBest, we will tell you at least 30 days before.

Our responsibility

We work to keep FitBest running and your data safe, but we can't promise it will always be available or free of errors. As far as the law allows, we are not responsible for indirect losses, and our total responsibility is limited to what you paid us in the 12 months before the problem. Nothing here takes away rights you have as a consumer under the law where you live.

Law

These terms follow the laws of Brazil. If you are a consumer, you can also go to the courts where you live.

Changes

If prices or these terms change, we tell you before the renewal they apply to, so you can cancel first.
