Terms of use

Last updated: 4 November 2026.

These terms keep things fair in both directions. Plain English throughout, because that is the whole brand.

The service

Taper builds training plans, race predictions and training analysis from your imported running data. You need an account, and you sign in with a code sent to your email address, so keeping that mailbox secure is your responsibility.

Not medical advice

Taper is a training tool, not a doctor or a physiotherapist. Plans and predictions are built from your data, but only you know how your body feels. Train sensibly, and get medical advice before training hard if you have any condition that calls for it.

An assistant you connect, such as Claude or ChatGPT, acts on your behalf. It can change anything you could change in the app, but only after it shows you the change and you say yes in that conversation, so a change you approve there is yours, as if you had made it in the app. Every change it makes is logged in Taper, and most can be undone; filing your plan away or starting a new one, disconnecting a service, resetting your data and deleting your account cannot, and Taper marks such a change as one that cannot be undone before you say yes. What it says to you is its own and can be wrong, so check anything that matters against your plan, and none of it is medical advice.

Your data, honestly handled

Numbers in Taper come from your recorded activities and models on top of them. We show where each number came from and how sure of it we are, but we do not guarantee any prediction; a race result is decided on the day, not in the app. See the privacy policy for how data is handled.

Data from Garmin

If you connect Garmin, the data that comes from it is for you to use in Taper and no one else. Do not use Taper to copy it out in bulk, resell it or pass it to anyone else, and do not use it to train or test an AI model. Garmin's own terms apply to your Garmin account, and Garmin can withdraw Taper's access to it.

Fair use

Do not attempt to break, overload or reverse the service, access other people's data, or use Taper for anything unlawful. We may suspend accounts that do.

Availability and liability

Taper is provided as is, without warranty. We work to keep it up and correct, but we are not liable for training decisions, missed workouts, race outcomes or losses arising from downtime or data issues, to the maximum extent the law allows. Nothing in these terms limits liability that cannot lawfully be limited.

Changes and contact

We may update these terms; material changes will be announced in the app. These terms are governed by the law of England and Wales. Questions: info@taperapp.co.uk.
