Terms
Last updated 5 November 2026
Naru is in closed testing. These terms are deliberately short and in plain English, and they will grow before it opens to the public.
Naru is not a doctor
This is the important one. Naru builds training plans and estimates how much energy you need. It is not medical advice, it cannot examine you, and it does not know what it has not been told.
Talk to a doctor before starting a training programme, especially if you have a heart condition, are pregnant, are returning from injury or illness, or have been told to be careful with exercise. If something hurts in a way that is sharp, sudden or not improving, stop and get it looked at. A plan is a suggestion, not an instruction, and no session is worth an injury.
What the numbers are worth
The load values, training zones and fuel targets in Naru are derived from published research and from our own calibration. They have not been signed off by a qualified coach or a registered dietitian. Where a figure rests on a method that is not validated, the app says so on the screen rather than presenting it as fact. Treat them as a considered starting point and adjust from how you actually feel.
Your account
Keep your sign-in to yourself, and tell us if you think someone else has it. One account is one person — the plan is built from your answers and would be wrong for anybody else.
Connected services
When you connect Strava, Garmin or COROS you are giving Naru permission to read your activities from that service, and in some cases to write planned sessions to it. You can withdraw that at any time from Connections, and you remain bound by that service’s own terms as well as these.
Your data
Your training data is yours. We do not sell it or share it with advertisers, and you can delete it along with your account whenever you want. How it is handled is set out in the privacy policy.
What we ask of you
- Do not try to break into other people’s accounts or data.
- Do not scrape, resell or redistribute the training content.
- Do not use Naru to coach other people commercially without talking to us first.
Availability
Naru is a small product in testing. It will sometimes be down, and features will change or be removed. We will not pretend otherwise. If we have to stop running it we will give you notice and a way to get your data out.
Liability
Naru is provided as it is. To the extent the law allows, we are not liable for injury, loss or damage arising from following a plan, from a connected service, or from the app being unavailable. Nothing here limits liability for death or personal injury caused by negligence, or for fraud — that cannot be excluded and we are not trying to.
Law
These terms are governed by the law of England and Wales.
