Terms of Service

Including subscription terms · Last updated: October 13, 2026

The short version

1. Who we are

Momentum is a habit app at momentum.zaeralabs.com and in the Momentum Android app. It is provided by Zaera Labs LLC, a New Mexico limited liability company ("we", "us"). By using Momentum you agree to these terms. Questions: support@zaeralabs.com.

2. What Momentum is, and isn't

Momentum helps you plan habits and keep track of them. It is a self-tracking tool, not medical, nutritional or fitness advice. Some ready-made plans involve exercise or diet: check with a doctor before you start if you have a health condition, are pregnant, or are unsure whether a plan is right for you.

3. Your account

You can use Momentum without an account; your data then stays on your device. With an account (Google, email and password, or an emailed code) your data is backed up so you can restore it. Keep your sign-in details safe; you're responsible for what happens under your account. You can delete your account at any time in Settings. Momentum is not meant for children under 13.

4. Free and Pro

Free: any one ready-made plan, checking off its habits, the weekly progress ring, a daily reminder that works while the app is open, backup and CSV export.

Momentum Pro is an optional paid subscription that adds streaks, XP, levels, badges and celebrations; building your own plans and editing plans; unlimited plans and habits; live sync across devices; real notifications that reach you even when the app is closed, including a reminder for each habit at its own time; the Progress tab, complete history and charts.

We may improve or change features over time. We won't remove a Pro feature you have paid for during the period you paid for.

5. Prices and billing

6. Cancelling

Cancel any time in the Google Play Store → Profile → Payments & subscriptions → Subscriptions → Momentum. Cancel at least 24 hours before the renewal date to avoid the next charge. After you cancel, Pro stays active until the end of the period you've paid for.

Deleting your Momentum account does not cancel your Google Play subscription. Cancel it in Google Play first.

7. Refunds

Refunds are handled by Google Play under its refund policy. If something went wrong, write to support@zaeralabs.com and we'll help. When a payment is refunded, Pro ends.

8. Payment problems

If a renewal payment fails, Google Play retries it for a short grace period and Pro stays active meanwhile. If it still fails, Pro is put on hold until the payment method is fixed in Google Play.

9. When Pro ends

Your data is never deleted because Pro ended. Your streaks, XP and badges are kept and come back when you subscribe again. If you have more than one plan, you choose which one stays active; the others stay visible and read-only.

10. Fair use

Don't misuse Momentum: no attempts to break or overload it, to access other people's data, or to get around payment. We may suspend accounts that do.

11. Liability

Momentum is provided "as is" and "as available". To the extent the law allows, Zaera Labs LLC is not liable for indirect, incidental or consequential losses, and our total liability is limited to what you paid us in the 12 months before the claim. Nothing in these terms limits rights you have under the consumer laws where you live.

12. Changes, law and contact

If we change these terms in a material way, we'll update the date above and tell you in the app. These terms are governed by the laws of the State of New Mexico, USA, except where the consumer laws of your country say otherwise. Questions: support@zaeralabs.com.
