What we send to AI

Version 20 October 2026

Your coaches are AI. Their replies, plans and sessions are written by Claude, a model made by Anthropic, from what you have told YourHPU. Each time a coach works for you, the parts of your data it needs go to Anthropic with the request. This page lists them.

01

What every coach sees in chat

  • your first name, age, sex, height, weight, sport, goals, benchmarks, training history, equipment, injuries and schedule
  • today's check-in (sleep, soreness, stress) and readiness
  • your season plan, this week's and next week's plans and sessions, and the sessions you logged in the last 7 days
  • your nutrition targets and today's totals
  • coach memory (short notes such as an injury or a busy week) and recent change proposals
  • your chat with that coach

In what you type (chat, notes, memory), email addresses, phone numbers, street addresses and card numbers are replaced with a placeholder before it is sent. Other people's names are not.

02

Coach by coach

Head Coach
Everything above, plus short notes the other coaches pass on to it (for example, that you mentioned a sore knee in the Strength chat). It reviews every change another coach proposes, and on amber and red days it talks today through with you. During setup, Head Coach reads your intake answers (first name only) to ask up to three follow-up questions.
Season Planning
Your profile, your goal event and date, your weekly availability and training history, to build the season and week plans.
Strength and Conditioning
Your profile, the week plan, coach memory (constraints and injuries), and changes you approved, to write each week's sessions; in chat, everything above.
Nutrition
Everything above, plus your food library. When you log food, your message goes as you typed it (not cleaned), so amounts and codes stay exact. For a branded food it doesn't know, it searches the web for the label, sending only the product name and your timezone (to find local brands).
Mindset
Everything above. It never changes your plan; if something needs changing it asks the coach who owns it.

03

What AI never sees

  • your email address, surname or date of birth;
  • your password;
  • email addresses, phone numbers, street addresses or card numbers you type (replaced first);
  • other athletes' data.

04

What Anthropic does with it

We use Anthropic's commercial service. Anthropic may not train its models on what we send, and deletes it within 30 days (up to 2 years for anything its automated safety systems flag). Details and sources are in the privacy policy.

05

Our records of AI calls

We keep a record of each AI call (what was sent and what came back, cleaned as above) for 30 days, to fix problems and improve the coaching. Only the owner can read them. They are then deleted automatically.

06

Deleting it

Delete account on your account page deletes your data and these records straight away. To ask about or delete anything else, write to rory@yourhpu.com.

07

AI isn't a person

Coaches can be wrong, and they are not doctors, physios or counsellors. If you are struggling, talk to a person today: your GP, someone you trust, or one of these free lines.
