Terms of Service

Last updated: 14 April 2026

1. Acceptance of these terms

These Terms of Service ("Terms") are a binding agreement between you and the operators of Aithlo. By creating an Aithlo account, signing in, or using any Aithlo product — including the Aithlo web app, Aithlo-Shift, and any future Aithlo mobile app — you agree to these Terms. If you do not agree, you must not use Aithlo.

These Terms work together with our Privacy Policy and Health and Training Disclaimer. Please read all three documents.

2. Who we are

Aithlo is based in France. A legal entity is currently being prepared and will be put in place before Aithlo enters production. In these Terms, "we", "us", and "Aithlo" refer to that legal entity once formed, and in the meantime to the individuals operating Aithlo during its pre-production phase. These Terms will be updated to name the legal entity as soon as it is registered. "You" means the individual using Aithlo.

You can contact us about these Terms at privacy@aithlo.com.

3. Who can use Aithlo

To create an Aithlo account, you must:

Be on Aithlo's private beta invitation list — during the pre-production phase, signup is restricted to users we have invited individually, and the beta is capped at 50 participants
Be at least 16 years old
Live in the United Kingdom or France (we will add more countries over time)
Provide a real email address and accurate signup information, including your actual date of birth
Have one account only — we do not allow multiple accounts per person
Not be legally prohibited from using Aithlo in your country

We may suspend or delete accounts that we believe belong to under-16s, users outside our supported countries, or users who provided false signup information.

4. What Aithlo provides

Aithlo provides:

Training plans and workouts generated by an AI coach based on the data you give us
An AI chat coach that can answer questions about training and generate workouts, charts, and plans on demand
Activity sync from Strava, so we can analyse your training history
Aithlo-Shift, a virtual cycling simulator that connects to Bluetooth trainers and heart rate monitors
Coaching and social features that let you connect with coaches and friends and ride together in Aithlo-Shift

Aithlo is currently in active development. Features may change, be added, or be removed. Downtime and bugs are expected. We do not promise that Aithlo will be available 24/7, free of errors, or compatible with every device. You should not rely on Aithlo for anything that requires guaranteed uptime.

Private beta status.

Aithlo is currently a private, invite-only beta and is not yet a production service. Access is strictly limited to a closed list of users invited individually, capped at 50 participants. There is no public signup, no app store distribution, and no payments. Aithlo is currently operated pre-incorporation: a legal entity is being prepared and will be formed before Aithlo enters public production, at which point these Terms will be updated. By participating in the private beta, you accept that the service is not final, that downtime, bugs, and data loss may occur, and that anything about Aithlo that is important to you should be backed up elsewhere (for example in Strava). You can leave the beta at any time by deleting your account in Settings or emailing privacy@aithlo.com.

5. Your account and responsibilities

You are responsible for:

Keeping your password secret. Never share your password or account with anyone.
Notifying us immediately at privacy@aithlo.com if you believe your account has been accessed without your permission.
Everything that happens under your account, including if someone else uses it with or without your knowledge.
Providing accurate information when you sign up and when you update your profile. Aithlo generates training plans based on what you tell us; inaccurate profile information produces bad plans.

If we detect repeated failed login attempts on your account, we will temporarily lock it for 15 minutes as a security measure.

6. Acceptable use

When you use Aithlo, you agree that you will not:

Use Aithlo for any unlawful purpose
Impersonate another person, use a false identity, or pretend to be someone you're not
Upload, share, or feed Aithlo data that belongs to someone else without their permission (for example, their Strava activities, their photo, or their personal information)
Attempt to access another user's account, data, or coach relationship
Reverse engineer, decompile, or otherwise try to extract the source code of Aithlo
Scrape, crawl, or systematically download data from Aithlo's servers, beyond normal use of the app
Abuse or overload the API with automated requests
Use Aithlo to harass, threaten, or send abusive messages to coaches or other users
Attempt to manipulate or trick the AI coach into producing harmful, illegal, or misleading content
Upload malware, viruses, or content designed to disrupt Aithlo or its users
Circumvent any security, access control, rate limit, or age restriction
Use Aithlo in a way that would expose us to legal liability

We may suspend or delete accounts that violate this section without notice.

7. Your content

When you upload an activity, write a chat message, create a route, send a message to a coach, or otherwise contribute content to Aithlo, that content is "Your Content".

You own Your Content. Aithlo does not claim ownership of your activities, messages, routes, or any data you produce.
You grant us a licence to store, process, display back to you, and use Your Content as strictly necessary to operate Aithlo and provide the services described in Section 4. This licence is limited to what we need to run the app — we do not license Your Content for marketing, resale, training AI models, or any other purpose.
You are responsible for Your Content. You must have the legal right to upload, share, and process anything you submit to Aithlo. If Your Content infringes someone else's rights, causes harm, or violates the law, that is your responsibility.
We may remove content that we believe violates these Terms or the law, without prior notice.

8. Third-party services

Aithlo integrates with several third-party services: Strava, Google (Sign in with Google), OpenAI (the AI coach), and others listed in our Privacy Policy. Your use of those services is subject to their own terms and privacy policies, not ours.

When you connect Strava, you agree to Strava's Terms of Service and Strava's API Agreement.
When you sign in with Google, you agree to Google's Terms of Service.
When you chat with the AI coach, your messages are sent to OpenAI. Aithlo is not responsible for how OpenAI processes that data beyond what we promise in our Privacy Policy.

If a third-party service changes or removes an integration (for example, if Strava revokes our API access), we may lose the ability to provide that feature. We will not owe you compensation if this happens.

9. AI-generated content — read this carefully

Aithlo's AI coach generates training plans, workouts, advice, and other content in response to your data and your questions. You must understand the following before using any AI-generated content:

AI-generated content is produced by a large language model and can be wrong, incomplete, inappropriate, or dangerous. Large language models are statistical, not medical.
AI-generated content is not medical advice and must never be treated as such. Aithlo is not a medical device, not a medical service, and does not replace a qualified doctor, physiotherapist, or sports physician.
You train at your own risk. If you follow a plan the AI generates, you do so understanding that the plan may be wrong for your body, your health condition, or your current state. You remain responsible for your own training decisions.
Stop immediately if any exercise, workout, or instruction causes pain, unusual symptoms, or discomfort, and consult a medical professional.
Before starting a new training programme, especially if you have any pre-existing health condition, you should consult a doctor.
Please read our full Health and Training Disclaimer.

By using Aithlo, you accept that the AI coach is a tool, not a clinician, and that you are the person responsible for what you do with its output.

10. Intellectual property

Aithlo, including its name, logo, design, software, website, app, Aithlo-Shift, source code, and all text, graphics, and materials we create, is owned by us or licensed to us. Nothing in these Terms transfers any of our intellectual property to you.

You may use Aithlo for your personal, non-commercial training. You may not copy, resell, redistribute, white-label, or otherwise commercialise any part of Aithlo without our written permission.

11. Termination

You can delete your account at any time in Settings. When you do, we delete your personal data from our production database on the same day (see our Privacy Policy for detail).
We can suspend or terminate your account at any time, with or without notice, if we reasonably believe that you have violated these Terms, that your account has been compromised, that your use of Aithlo poses a risk to us or other users, or that we are legally required to do so.
We can discontinue Aithlo at any time. If we do, we will try to give reasonable notice and to let users export their data first, but we are not legally required to.
Sections that survive termination: your obligations under Sections 6 (Acceptable use), 7 (Your content), 9 (AI-generated content), 10 (Intellectual property), 12 (Disclaimers), 13 (Limitation of liability), and 15 (Governing law) continue to apply after your account is closed.

12. Disclaimers

To the maximum extent permitted by law, Aithlo is provided "as is" and "as available", without any warranty of any kind, express or implied. We specifically disclaim the following:

That Aithlo will be uninterrupted, error-free, bug-free, secure, or always available
That training plans, workouts, or advice generated by the AI coach are correct, safe, appropriate for your condition, or suitable for any particular purpose
That Aithlo is fit for any particular purpose, including competitive training, medical purposes, or any purpose where reliability is critical
That any data calculations or analytics in Aithlo are accurate
That integrations with third-party services (Strava, Google, OpenAI, etc.) will continue to work

Nothing in this section excludes or limits any liability that cannot be excluded under applicable law — for example, liability for death or personal injury caused by our gross negligence, or rights you may have as a consumer under French or UK law.

13. Limitation of liability

To the maximum extent permitted by law, we are not liable for:

Any indirect, incidental, consequential, or special damages
Loss of profit, loss of data, loss of fitness progress, loss of race performance, or loss of opportunity
Injury, illness, overtraining, or any physical consequence arising from your use of Aithlo or from following an AI-generated training plan
Any damage caused by a third-party service (Strava, Google, OpenAI, Hetzner, Aiven, etc.) whether or not we use that service
Any content, action, or message from a coach, friend, or other user on Aithlo
Events outside our reasonable control, including internet outages, denial-of-service attacks, force majeure events, and third-party service failures

If, despite the above, we are found liable to you for any reason connected to your use of Aithlo, our total aggregate liability across all claims shall not exceed the greater of (a) €100 or (b) the total amount you have paid us for Aithlo in the 12 months before the claim arose. (At the time these Terms are published, Aithlo is free, so the floor is €100.)

Nothing in this section excludes or limits any liability that cannot be excluded under applicable law.

14. Indemnity

You agree to defend, indemnify, and hold us harmless from any claim, demand, loss, liability, or expense (including legal fees) arising out of or related to:

Your violation of these Terms
Your violation of any law or the rights of any third party
Content you uploaded or submitted to Aithlo
Your misuse of Aithlo or the AI coach

15. Governing law and disputes

These Terms are governed by French law. Any dispute arising out of or in connection with these Terms, Aithlo, or your use of Aithlo shall be subject to the non-exclusive jurisdiction of the courts of France.

If you are a consumer resident in the European Union or the United Kingdom, you may have additional rights under your local consumer protection law that cannot be waived by these Terms. Nothing in this section affects those rights, and you may still bring proceedings in the courts of your country of residence where permitted by law.

Before going to court, please email us at privacy@aithlo.com. We genuinely want to resolve disputes directly and quickly.

16. Changes to these Terms

We may update these Terms as Aithlo evolves. When we make changes that materially affect your rights or obligations, we will notify you by email and ask you to accept the new version the next time you sign in. Minor changes (for example, clarifications or typo fixes) may be made without notice. The date at the top of these Terms always reflects the most recent version.

If you do not agree to the new version of the Terms, your remedy is to stop using Aithlo and delete your account.

17. General

Entire agreement. These Terms, together with the Privacy Policy and Health and Training Disclaimer, form the entire agreement between you and us regarding Aithlo.
Severability. If any part of these Terms is held unenforceable, the rest continues to apply.
No waiver. If we do not immediately enforce a provision of these Terms, that is not a waiver of our right to enforce it later.
Assignment. You may not transfer your account or these Terms to anyone else. We may transfer these Terms to a legal entity we form or to a successor business.
Language. These Terms are published in English and French. In case of any conflict between the two versions, the French version prevails for users resident in France, and the English version prevails for users resident in the United Kingdom.
