Terms of use

Version 1, 31 October 2026.

What this is

Pace Puffin is an AI running coach, run by Justyn: one person, not a company. It's a free beta: free while the beta runs, and nothing is ever charged without asking you first. It can change, pause or stop. You agree to these terms when you set it up or connect Garmin Connect to it, and by using it.

Who can use it

Anyone aged 18 or over, for their own training.

Not medical advice

Your coach is software and an AI, not a doctor, physiotherapist or human coach, and it can be wrong. It suggests training from your data. You decide what to do, and you're responsible for your training and your health. If you have pain, an illness or an injury, or anything worries you, stop and see a professional. Check with a doctor before training hard if you have a health condition. In an emergency, call your local emergency number.

Your AI app

Your coach runs in Claude (made by Anthropic) or ChatGPT (made by OpenAI), with your own account. That account, any plan you pay for, and what Anthropic or OpenAI do with your chats are between you and them, under their terms and privacy policies: Anthropic's terms and privacy policy, OpenAI's terms and privacy policy. Your chats stay in your account: Pace Puffin gets only what your app sends the coach's tools, as the privacy policy says. Before you connect Garmin Connect, turn off the setting that lets them use your chats to improve their models (AI transparency).

Your data

What's kept, where, who can see it, and what AI does with it are in the privacy policy, which is part of these terms.

Fair use

Use the coach for your own training. Keep your coach address and your Garmin link to yourself: each works like a password. Don't try to reach anyone else's data, get around the service's limits, or disrupt it.

Garmin

If you connect Garmin Connect, Garmin sends your data to Pace Puffin under Garmin's own terms with you. Garmin doesn't run, endorse or sponsor Pace Puffin. Garmin is a third-party beneficiary of these terms and may enforce them. As far as the law allows, Garmin gives you no warranty and has no liability to you for Pace Puffin or for your data in it, and you release Garmin from claims arising from your use of it.

No warranty, and limited liability

Pace Puffin is given as it is, free. There's no promise that it's available, accurate or right for you. As far as the law allows, Justyn isn't liable for any loss or harm from using it, including from training you choose to do. Where the law where you live doesn't allow a limit like this, it applies only as far as that law allows.

Leaving, and ending

You can leave at any time: tell your coach you want to leave. You're removed within 7 days. If you connected Garmin Connect, you can cut it off at once on your Garmin page or in Garmin Connect. Justyn can end your access if you break these terms or misuse the service, and can end the beta for everyone, telling you first. When you leave, or the beta ends, your data is deleted as the privacy policy's Leaving section says.

Changes

Each version of these terms has a number and a date. If a change matters, Justyn tells you before it takes effect, and you're asked to agree again before you next connect Garmin Connect or upload a Garmin export.

Law

These terms are under the laws of the Province of Alberta and the federal laws of Canada that apply there.

Report misuse or a problem

Tell your coach, which sends your words to Justyn once you say yes: someone using your coach address, data that isn't yours, a security problem, or a coach saying something harmful.
