Bring your history in, take it out again
Import your history from the app you used before, connect the products you already use, and read your own record over an API you control.
Bring your history in
Import your workout and bodyweight history from another app instead of starting from an empty log, so progression has data to work from on day one. Import is free, because charging to bring your history over would defeat the purpose.
The importer records where each row came from, so an imported set is labelled as imported in your log and in the analytics that read it.
Connect the products you already run
MuscleBuddy links to partner products so what you track in one shows up in the other. A connection links two accounts you own, and you can break it from either side. It transfers no ownership.
Separately, you can grant a partner a scope over your data: what it may read and for how long, revocable when you change your mind. MuscleBuddy does not sell access to your record, and a connection gives a partner only the scope you named.
Ask ChatGPT or Claude about your training
Connect MuscleBuddy to ChatGPT or Claude and ask the assistant about your own record: how your bench has moved this block, what your program has you doing on Thursday, whether your recovery suggests easing off. Add MuscleBuddy as a connector in the assistant, sign in, and choose on our consent screen exactly what it may read: your workouts and program, your daily recovery score, your nutrition targets, your pets.
The assistant reads only when you ask it something that needs the data, and only what you ticked. Everything it says about your data is its own AI-generated answer, not MuscleBuddy coaching, and every read reminds it to say so. You can disconnect it from your settings at any time, which ends its access at once. It is free on every tier.
Read your own record over an API
Mint a personal access token and read your own workouts, personal records, food logs and bodyweight over a documented API scoped to your account. It is the same data the app shows you, available to a script, a spreadsheet, or whatever you build.
A token reads by default. You can also mint one with write access, so a script or another app can log workouts, food, weigh-ins, lab markers and vitals into your account. Treat a write token like a password: one that leaks can change your log until you revoke it.
Listing and revoking a token stay free on every tier, so an account that lapses can still see and revoke a credential it created. An already-minted token keeps reading. You need Pro to mint a new token, and you don't need it to keep using one you have.
Leaving is supported
Every member on every tier can export their full account, and deleting the account deletes the record instead of hiding it. Coaches lose access to a client's data when the relationship ends, because the data belongs to the client.
Frequently asked
- Does importing my history cost anything?
No. Free: importing your history from another app; connecting a partner product, and the scopes you grant it; and connecting ChatGPT or Claude to read your training. Pro covers minting a personal access token for the API.
- What can a connected partner product see?
Only the scope you granted it, for as long as you leave that grant in place. You can see every active grant in your settings and revoke any of them, which takes effect immediately.
- Can ChatGPT or Claude change anything in my account?
No. The connector reads, and only the kinds of data you ticked when you connected it. What the assistant tells you is its own AI-generated answer. Your program and your coach stay in charge of your training.
- Is the API read-only?
Only if you want it to be. A token reads your own data by default, and you choose when you mint it whether it can also write. A write token that leaks can change your log until you revoke it.
- What happens to my data if I stop paying?
It stays yours. Pro features stop, the record does not: you keep reading, exporting and deleting your own data on the free tier, and an access token you already minted keeps working.
- Can I get everything out at once?
Yes. A full account export covers your training, nutrition, health and account records in one file, on any tier, and you run it yourself.
Start with the history you already have
Import from the app you are leaving, connect what you already run, and read it all back whenever you want. Free: importing your history from another app; connecting a partner product, and the scopes you grant it; and connecting ChatGPT or Claude to read your training.
