Terms of Service

Last updated: August 2026

By using Marginal Gains, you agree to these terms. We’ve kept them short and in plain language.

The service

Marginal Gains is a free habit-tracking app. You can use it as a guest, with data stored only in your browser, or create an account to sync your progress across devices. There is no paid tier and no payment information is collected.

Your account

You’re responsible for the accuracy of the information you provide and for keeping your login credentials secure. You can delete your account at any time from Settings — this permanently removes your data and cannot be undone.

Not medical advice

Marginal Gains is a habit-tracking tool, not a medical, nutrition, or fitness professional. Nothing in the app constitutes medical advice. Consult a qualified professional before making significant changes to your diet, exercise, or sleep routine.

Groups & community content

If you join or create a group, other members can see your display name, streak, and completion counts. Be respectful of other members. We may remove content or restrict accounts that are abusive, spammy, or otherwise harmful to the community.

Changes

The app is actively developed and features may change, be added, or be removed over time. We’ll use reasonable efforts to avoid disrupting your existing data when we do.

No warranty

The service is provided “as is,” without warranties of any kind. We aren’t liable for missed habit reminders, data loss, or any decisions you make based on information shown in the app.
