Tessera Fit

Terms of use

Last updated 11 November 2026

These terms apply when you use the Tessera Fit website at tesserafit.app and the Tessera Fit app. Tessera Fit is a registered business name of Jacob Sullivan, a sole trader in New South Wales, Australia (ABN 73 141 573 448). By using Tessera Fit, you agree to these terms. If you don't agree, please don't use it.

1. What Tessera Fit does

Tessera Fit brings together training and health data from services you connect and files you upload, such as Garmin Connect, Hevy, Strong, Apple Health and FIT files, and shows it in one place. Tessera Fit is in development, so features, supported apps and plans may change, be added or be removed.

2. Waitlist and founding membership

Joining the waitlist is free and doesn't commit you to anything. Founding membership is offered to people on the waitlist when Tessera Fit opens. A founding member pays A$39 a year for Pro, and that price stays the same for as long as the membership continues without a break. Nothing is charged until you choose a plan.

3. Not medical advice

Tessera Fit shows information about your training. It is not a medical device and does not diagnose, treat or prevent any condition. Metrics such as training load and recovery are estimates and can be wrong. Talk to a doctor or other qualified professional before making decisions about your health, and stop exercising and get help if you feel unwell.

4. Your account

  • You must be at least 16 years old to use Tessera Fit.
  • Give us accurate information and keep your login details secure. Tell us straight away at [email protected] if you think someone else has accessed your account.
  • You can stop using Tessera Fit and delete your account at any time.

5. Connected services

When you connect another service, you authorise Tessera Fit to read your data from it on your behalf. Your use of that service is governed by its own terms and privacy policy. Tessera Fit depends on those services to provide data, so if one of them changes or stops its access, some features may stop working. Tessera Fit is not affiliated with, sponsored by or endorsed by Garmin, Apple or Hevy.

6. Your data

Your training and health data belongs to you. You give us permission to store, process and display it only so we can provide Tessera Fit to you. How we handle it is set out in our privacy policy.

7. Acceptable use

Don't use Tessera Fit to:

  • break the law or anyone's rights;
  • access another person's account or data without their permission;
  • interfere with, overload, probe or reverse-engineer Tessera Fit or the services it connects to;
  • scrape, resell or redistribute Tessera Fit or data obtained through it;
  • upload files you don't have the right to share, or files designed to harm our systems.

We may suspend or close an account that breaks these terms. Where it's reasonable to, we'll tell you why first.

8. Our content

The Tessera Fit name, logo, website and app are owned by us. You may not copy or use them except as needed to use Tessera Fit.

9. Your rights under Australian Consumer Law

Nothing in these terms excludes, restricts or changes any rights you have under the Australian Consumer Law or other laws that can't be excluded. Our services come with guarantees that cannot be excluded under the Australian Consumer Law.

10. Limits on our responsibility

To the extent the law allows:

  • Tessera Fit is provided as it is. We work to keep it accurate and available, but we can't promise it will always be error-free or uninterrupted, or that data from connected services will always be complete;
  • we are not responsible for loss caused by connected services, by events outside our reasonable control, or by decisions you make based on information shown in Tessera Fit;
  • where our liability for failing to meet a consumer guarantee can be limited, it is limited to supplying the service again or paying the cost of having it supplied again.

11. Changes to these terms

We may update these terms as Tessera Fit changes. The date at the top shows when they were last updated. If we make a significant change, we'll tell you by email or in the app before it takes effect.

12. Governing law

These terms are governed by the laws of New South Wales, Australia. You and we submit to the courts of New South Wales and the Commonwealth of Australia.
