These terms of use govern your use of the Myo mobile app (formerly MyoScore) and of the services offered through it (the "Service"). Please read them together with our Privacy Policy, which explains how we handle your personal information.
1. Who we are
Myo is provided by SépiaLab, an individual business registered in Québec, Canada, which publishes apps under the name Sépia ("we", "us", "our"). You can reach us at support@bysepia.com.
2. Accepting these terms
By downloading, opening or using Myo, you accept these terms. If you do not accept them, do not use the app.
3. Adults 18 and over only
You must be at least 18 years old to use Myo. By using it, you confirm that you are. We ask for your birth month and year, we block devices and accounts identified as belonging to a minor, and we delete photos of anyone detected as a minor.
4. The Service
Myo helps you follow your physical progress with photos. You take front, side and back photos, and the app analyzes them with artificial intelligence to give you observations for each body zone, trends between your scans, three training priorities and a training program built around your week. A new scan can be done every 4 weeks.
The results are automated estimates based on photos. Lighting, pose, clothing and the camera can change them, and they may be incomplete or inaccurate. They are not measurements of your weight, your body fat or your health. We may improve, change or remove features over time.
5. Not medical advice
Myo is not a medical device. It does not provide medical advice, diagnosis or treatment. Talk to a doctor or another qualified health professional before starting a training program, especially if you are pregnant, injured or have a medical condition, and whenever you have concerns about your health, your eating or your body image. Stop exercising and seek medical help if you feel pain, dizziness or shortness of breath.
6. Your account
Myo creates an account for you automatically, without asking for your name, and your photos and results are linked to it. If you sign in with an existing account, keep your login details confidential. You are responsible for keeping your device secure. If you change phones or reinstall the app and cannot find your data or your subscription, contact us and we will help.
7. Your content
Your photos and the information you enter remain yours. You give us a non-exclusive, worldwide, royalty-free licence to host, store, copy and process them only to operate the Service for you (for example, to analyze your photos and show your progress) and to enforce these terms and the 18+ rule. This licence ends when your content is deleted, except for what we must keep by law. We never use your photos for advertising, we never sell them and we never show them publicly.
8. Acceptable use
When you use Myo, you agree to:
- upload only photos of yourself;
- make sure no one else appears in your photos, and never upload a photo of a minor;
- not upload nude photos: wear fitted sportswear;
- not upload content that is illegal, sexual, violent or hateful, or that infringes someone else's rights;
- not bypass the age check, the scan limits, the free trial or payments, for example by creating several accounts;
- not copy, modify, reverse engineer or extract the source code of the app, except where the law allows it, and not access the Service by automated means or interfere with its security;
- use Myo only for your personal, non-commercial use.
If you break these rules, we may delete the content concerned and suspend or close your account.
9. Subscriptions, free trial and payments
- Free first scan. Your first scan is free and sets your starting point. Your three training priorities, your program and your following scans require a subscription.
- Plans and prices. Subscriptions are sold through the Apple App Store or Google Play and charged to your store account. The available plans (for example, monthly and yearly), their price and what they include are shown in the app and in the store before you confirm.
- Free trial. The yearly plan may include a free trial, typically 7 days, for eligible new subscribers. Apple or Google determines eligibility. Payment is charged at the end of the trial unless you cancel at least 24 hours before it ends. If notifications are on, the app reminds you before the trial ends. Any unused part of a free trial is lost if you buy a subscription during the trial.
- Automatic renewal. Subscriptions renew automatically for the same period at the current price unless you cancel at least 24 hours before the end of the current period. Your store account is charged for the renewal within the 24 hours before the end of the period.
- Cancelling. You can manage and cancel your subscription at any time in your store settings: on iPhone, in Settings, then your name, then Subscriptions; on Android, in Google Play, then Payments and subscriptions. After you cancel, you keep access until the end of the period already paid. Deleting the app or your Myo account does not cancel your subscription.
- Price changes. If a price changes, Apple or Google informs you in advance under its rules and, where required, asks for your consent before the renewal.
- Refunds. Payments are processed by Apple or Google, which handle refund requests under their own policies. This does not affect the rights you have under consumer protection law.
10. Apple users
If you use Myo on an Apple device, the Apple Standard End User License Agreement also applies: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/. Apple is not a party to these terms and is not responsible for the app or its content.
11. Availability, changes and termination
We work to keep Myo available, but we cannot guarantee that it will always work without interruption or errors. Some features require an internet connection, and your mobile operator's data charges may apply. We may update, suspend or stop features, and if we permanently discontinue Myo, we will tell you in advance where possible.
You can stop using Myo at any time and ask us to delete your account by writing to support@bysepia.com. We may suspend or close your account if you seriously or repeatedly break these terms, if the law requires it, or to protect other users or the Service.
12. Intellectual property
Myo, its design, texts, graphics, software and trademarks belong to us or to our licensors. We give you a personal, limited, non-exclusive, non-transferable and revocable licence to use the app on devices you own or control, for your personal use, in accordance with these terms and the rules of the store you downloaded it from. Your content remains yours (see section 7).
13. Disclaimers
Myo is provided "as is" and "as available". To the extent permitted by law, we do not guarantee any particular result (for example, muscle gain, fat loss or a change in appearance), nor that the analyses will be accurate or that the app will meet your expectations. Your results depend on many factors, including training, nutrition, sleep and genetics. This does not affect the legal warranties you have as a consumer, including under the Québec Consumer Protection Act.
14. Limitation of liability
To the extent permitted by law, we are not liable for indirect damages, such as loss of data, loss of opportunity or decisions made based on the results of the app, and our total liability is limited to the amount you paid for Myo in the 12 months before the event that gave rise to the claim.
Nothing in these terms excludes or limits liability that cannot be excluded or limited by law, including our liability for bodily or moral injury, for intentional or gross fault, or under the Québec Consumer Protection Act. If you are a consumer in Québec, this section applies only to the extent that the law allows it.
15. Governing law and disputes
These terms are governed by the laws of the Province of Québec and the federal laws of Canada that apply there. Subject to the rules below, disputes are submitted to the courts of Québec, Canada. If you are a consumer, you keep the protection of the mandatory rules of the law of the place where you live, and you may bring a claim before the courts of your place of residence where the law allows it. Before going to court, write to us: most problems can be solved quickly.
16. Changes to these terms
We may update these terms when the app or the law changes. We will post the new version on this page with its effective date. If we make a significant change, we will tell you in the app at least 30 days before it applies. If you do not accept it, you can stop using Myo, cancel your subscription and ask us to delete your account, at no cost.
