Terms of service

Last updated: 1 March 2026

These terms of service govern your use of tendo, an AI-powered personal athletic coaching service accessible via Telegram and Messenger. By using tendo you agree to these terms.

1. What tendo is

tendo is an AI coaching assistant. It generates personalised training plans, analyses workout data from Strava, and provides session feedback through automated conversation. tendo is not a licensed medical provider, physiotherapist, or certified sports coach.

2. Eligibility

You must be at least 16 years old to use tendo. By using the service you confirm that you meet this requirement.

tendo provides general athletic coaching guidance only. Before starting any new training programme, consult a qualified healthcare professional — especially if you have any pre-existing medical conditions, injuries, or health concerns. tendo is not a substitute for professional medical advice.

You train at your own risk. tendo is not liable for any injury, illness, or harm that results from following a training plan or coaching advice provided by the service.

4. Your account and data

tendo stores your profile, goals, training plans, and conversation history to provide a personalised coaching experience. You can request deletion of all your data at any time by sending /delete to the bot or emailing hello@tendo.coach. See our Privacy policy for full details.

5. Strava integration

If you connect Strava, you authorise tendo to read your activity data (distance, pace, heart rate, etc.) to provide feedback and adjust your plan. You can revoke this access at any time from your Strava settings. tendo only reads activity data — it never writes to or modifies your Strava account.
