On your device
Your plan, log, check-ins, badges and chat are saved inside your browser on this phone or computer. Our website sends you the app; it never keeps your training.
Your details
Saved on this device only. Change anything and press Build my plan.
This is filled in with an example rower aiming for the British Rowing Indoor Championships, so you can see how it works. Replace it with your own details.
Training log
Minutes against plan, and training load from session effort (RPE × minutes).
| Week | Planned | Done | Load (AU) | Monotony | Strain |
|---|
Load = effort (1–10) × minutes . Monotony above 2.0 means too little variation between hard and easy days .

Privacy · this is cool!
Your data is yours. 100%.
The club doesn't keep your training data. There are no accounts, no club database of members, no tracking and no adverts. Your plan, every set you lift and every metre you row stay with you: on your device and, if you choose, in your own Google Drive. When you chat with the AI coach, your messages are processed by Anthropic to write the reply (details below).
In your own Google Drive
Turn on sync and a copy goes into a hidden folder in your Google account that only this app can open. One tap on Delete my Google Drive copy removes it. That's how your phone and laptop share the same data. It's your account and your storage, and we can't see in.
Concept2, read-only
Connect your Logbook and your sign-in is sealed, encrypted, in your own browser. Our server just passes your erg sessions straight through to your device and keeps nothing.
The AI coach
When you chat, your messages and a short summary of your recent training go to Claude (made by Anthropic) to write the reply, then come straight back to you. Only what the reply needs is sent: your training details and recent sessions, never your name. We don't keep the conversation; your device does.
What is sent, and when
| When you… | What leaves your device | Where it goes |
|---|---|---|
| Use the plan, workouts, log, badges | Nothing | Stays on your device |
| Chat with the AI coach | Your messages, plus only what that reply needs: your training details (no name), plan summary, recent sessions and check-ins, and any specialist modules | Anthropic, to write the reply. Not stored by the club |
| Answer a module's safety questions | Nothing. The coach only sees "passed" or "check with your doctor" | Stays on your device |
| Turn on research and ask a question | Search terms the coach writes (never your personal details) | Anthropic's web search, which looks only at medical and sports-science sources |
| Turn on device sync | Your whole training record | Your own Google Drive, hidden app folder |
| Connect Concept2 | A sealed sign-in in your browser | Concept2, read-only |
Why we're different
- Most fitness apps hold your data on their servers. They use it to build profiles of you, and it can be lost, leaked or sold. We built it the other way round.
- We can't lose, leak or sell what we never hold. There's no club database for anyone to break into.
- You can leave any time, taking everything with you. One tap downloads your whole history as a file, and one tap deletes it from this device.
- Your health information stays private. Heart rate, weight, injuries and how you slept are personal. They belong with you.
The small print, honestly
- AI coach: messages are processed by Anthropic to create replies, under Anthropic's privacy policy. To stop one person running up the club's bill, the server keeps only a scrambled code and message times, which it deletes within the hour. In this preview, the coach uses your own Claude account.
- Google: if you turn on sync, your data sits in your Google account under Google's terms. Our page fonts also load from Google Fonts.
- Our web host: like every website, cotswoldsportingclub.com's host keeps standard visit logs (address and pages requested), never your training data.
- YouTube: "Watch on YouTube" opens YouTube, where its own privacy terms apply.
- Not medical advice: plans are general guidance built on published research.
