Terms of Use
These terms are an agreement between you and Calisto. Please read them — section 5 covers health and safety, which matters because training carries real physical risk.
Calisto (“Calisto,” “we,” “us”) is provided by James Whelan. By downloading or using the app, you agree to these Terms of Use and to our Privacy Policy. If you don’t agree, don’t use Calisto.
1. Who can use Calisto
You must be at least 16 years old, or the minimum age of digital consent in your country, to use Calisto. If you’re under the age of majority where you live, you may only use Calisto with a parent or guardian’s consent. You’re responsible for activity under your account.
2. Your licence to use the app
We grant you a personal, non-exclusive, non-transferable, revocable licence to use Calisto on Apple devices you own or control, for your own non-commercial training. Calisto is licensed, not sold. Your use is also subject to Apple’s standard Licensed Application End User License Agreement; where these terms and Apple’s EULA conflict, Apple’s EULA governs for the app licence.
3. Your account
You sign in with Sign in with Apple. Keep your Apple Account secure — you’re responsible for what happens through your account. You can delete your account anytime in Settings → Delete Account.
4. Subscriptions and payments
Core training is free. Calisto Pro is an auto-renewable subscription that unlocks every skill path, the week-to-week adapting plan, and the full Coach and Spotter.
- Pro Annual — $99.99/year, with a 7-day free trial for new subscribers.
- Pro Monthly — $14.99/month.
Prices are in USD and may vary by region. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless you turn off auto-renew at least 24 hours before the end of the current period; your account is charged for renewal within 24 hours before the period ends. Any unused part of a free trial is forfeited when you buy the subscription. You can manage or cancel in your Apple Account settings. Refunds are handled by Apple under its terms. If we change prices, we’ll give notice and any required consent will be obtained.
5. Health, fitness, and assumption of risk
Calisthenics is strenuous physical activity and carries a risk of injury. Read this section carefully.
- Calisto provides general fitness and training information. It is not medical advice, and it is not a substitute for a qualified physician, physiotherapist, or coach.
- Consult a healthcare professional before starting Calisto or any exercise program, especially if you’re pregnant, recovering from injury or surgery, or have any medical condition.
- Stop immediately and seek help if you feel pain, dizziness, shortness of breath, or any symptom that concerns you. Don’t “train through” pain.
- The Spotter is an assistive tool, not a safety device or a spotter in the human sense. It can’t prevent injury, catch you, or guarantee your form is safe.
- You are responsible for training within your ability, using safe equipment, and choosing a safe environment. To the fullest extent permitted by law, you assume all risk arising from your training with Calisto.
6. AI features
The Coach generates responses using AI. AI can be wrong, incomplete, or out of date. Treat Coach replies as general guidance, check anything important, and never rely on them for medical, diagnostic, or emergency decisions. If a message suggests pain, injury, or a health crisis, please seek qualified help.
7. Your content and the Community
You keep ownership of the content you create — your logs, notes, and anything you post. If you use the optional Community feed, you grant us a worldwide, non-exclusive, royalty-free licence to host, store, and display that content for the purpose of operating the feed.
When posting, you agree not to share content that is unlawful, harassing, hateful, sexually explicit, infringing, or that depicts or endangers minors. We may remove content and suspend or terminate accounts that break these rules. You can report posts, block users, and delete your own posts. Content posted by other users is their responsibility, not ours.
8. Acceptable use
Don’t misuse Calisto. In particular, don’t reverse-engineer, decompile, or tamper with the app; don’t scrape, resell, or commercially exploit it; don’t attempt to break its security or interfere with other users; and don’t use it to break the law.
9. Intellectual property
Calisto, including its software, design, content, and brand, is owned by us and protected by law. These terms don’t give you any rights in our intellectual property beyond the licence above.
10. Third-party services
Calisto works with services run by others — including Apple, Anthropic, Strava, and the GORNATION store. Your use of those services is governed by their own terms and privacy policies, and we’re not responsible for them.
11. Disclaimers
Calisto is provided “as is” and “as available,” without warranties of any kind, whether express or implied, to the fullest extent permitted by law. We don’t warrant that the app will be uninterrupted, error-free, or that any result (including a particular skill or fitness outcome) will be achieved.
12. Limitation of liability
To the fullest extent permitted by law, Calisto and James Whelan will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, or goodwill, arising from your use of the app. Nothing in these terms limits liability that cannot be limited by law (such as for death or personal injury caused by negligence, where that exclusion isn’t permitted).
13. Indemnity
You agree to indemnify and hold us harmless from claims arising out of your misuse of Calisto, your content, or your breach of these terms.
14. Termination
You can stop using Calisto and delete your account at any time. We may suspend or end your access if you break these terms or if we stop offering the service.
15. Changes to these terms
We may update these terms as Calisto changes. We’ll update the date above and, for material changes, notify you in the app. Continuing to use Calisto after a change means you accept the updated terms.
16. Governing law
These terms are governed by the laws of [your jurisdiction], without regard to conflict-of-law rules, and the courts of that jurisdiction will have exclusive jurisdiction, except where mandatory consumer-protection laws in your country of residence say otherwise.
