These Terms govern your use of the Hybrid Athlete Pro iOS app and the optional AI Coach proxy service (together, the "Service"). By creating an account, completing onboarding, or otherwise using the Service you agree to these Terms. If you do not agree, do not use the Service.
Hybrid Athlete Pro generates personalised training plans by combining your stated sports, goals, equipment, and training history with a rule-based planning engine. The optional AI Coach feature surfaces an on-device or live-model-backed read of your plan and answers questions about your training.
The Service is for informational and educational purposes only.

If you have any medical condition (including but not limited to heart disease, high blood pressure, joint problems, recent surgery, pregnancy, or recovery from injury), you must consult a qualified healthcare professional before starting any exercise programme, including those generated by Hybrid Athlete Pro.
Exercise carries inherent risk of injury, including serious injury and, in rare cases, death. By using the Service you acknowledge and voluntarily assume all risks associated with the exercises, intensities, loads, and progressions you choose to perform, whether or not the Service suggested them.
You are responsible for:

The plans surfaced by the Service include conservative scaling notes, warm-ups, and intensity guidance to reduce risk, but they cannot substitute for your own judgement, your physician's advice, or in-person supervision.
You must be at least 18 years old to use the Service. The Service is not directed at minors and we do not knowingly accept users under 18. For data-protection purposes the Irish digital age of consent (16 years, per §31 Data Protection Act 2018) is the floor below which we will not knowingly process personal data — see our Privacy Policy §10.

The AI Coach feature uses one of two paths to generate its output:
iOS 26+, the Coach Note is produced by Apple's on-device language model. No data leaves your phone.
an anonymised digest of your recent training data to a Cloudflare Worker we operate, which forwards it to Groq, Inc.'s API (Llama 3.3 70B). The Worker strips your display name to a single initial before the call; the digest contains no email, real name, location, or persistent identifier.
The AI-generated text is not coaching advice from a qualified human coach and may contain errors, omissions, or recommendations that are inappropriate for your individual situation.
Treat AI Coach output as a discussion prompt or a second opinion, never as a substitute for your own judgement or a qualified coach. We do not guarantee the accuracy, completeness, or fitness-for-purpose of any AI Coach response.
The Service is offered as a paid auto-renewable subscription ("Hybrid Athlete Pro") managed through Apple's App Store. After the free onboarding — including a personalized plan preview — an active subscription is required to use the Service. Pro is offered as:

Under the EU Consumer Rights Directive (Directive 2011/83/EU, as transposed into Irish law by the European Union (Consumer Information, Cancellation and Other Rights) Regulations 2013), EU consumers normally have a 14-day right of withdrawal when purchasing digital content and services.
By starting your Pro subscription you expressly request that the Pro features become available immediately upon purchase and you acknowledge that, once the Service is fully performed (i.e. you have been granted access to the Pro features), the 14-day right of withdrawal no longer applies under Article 16(m) of the Directive.
This does not affect Apple's standard refund flow, which you can use at any time at <https://reportaproblem.apple.com> independently of this clause, nor your statutory rights under Irish or EU consumer-protection law.

To the maximum extent permitted by Irish and EU law, we disclaim all such warranties.
To the fullest extent permitted by applicable law (Irish and EU consumer-protection law preserves your statutory rights, which we do not exclude):

You agree to indemnify and hold harmless the operator (Can Ayan), its contractors, and its service providers from and against any and all claims, damages, losses, costs, and expenses (including reasonable legal fees) arising out of (a) your use of the Service, (b) your violation of these Terms, or (c) any injury or damage you cause to yourself or any third party while using the Service.
We may suspend or terminate your access to the Service at any time, for any reason, with or without notice, including for violation of these Terms. You may stop using the Service and delete your data at any time via Profile → Manage data → Delete account.
Provisions which by their nature should survive termination (including disclaimers, limitations of liability, indemnification, intellectual property, and dispute resolution) will survive.
We may update these Terms from time to time. Material changes will be posted at this URL with an updated "Last updated" date. Continued use of the Service after a change constitutes acceptance of the updated Terms.
These Terms are governed by the laws of Ireland, excluding its conflict-of-laws rules. Any dispute arising out of or in connection with these Terms will be resolved in the courts of Ireland, except where mandatory consumer-protection law assigns jurisdiction to your country of residence within the EU.
