Privacy policy

Last updated November 8, 2026

Axolo is a workout and nutrition app in private development. Sign-ups are closed. This policy covers the data Axolo keeps for an account, what it shares and with whom, including when you connect Axolo to Claude or ChatGPT.

Data Axolo keeps

Sleep and heart data are health data. Axolo uses them only to give you training context, and treats them as described under each section below.

Data Axolo accesses from Google

With permission, Axolo reads this Fitbit data through the Google Health API. Access is read-only.

Signing in with Google also gives Axolo your name, email address and Google account ID.

Data Axolo accesses from Apple Health

On iPhone, with your permission, Axolo reads your weight and body fat from Apple Health (HealthKit), including each reading's time, time zone and which app or device recorded it. It copies these to its database so your weigh-ins work across the app and the coach. When you type a weigh-in into Axolo, it also saves that weigh-in to Apple Health, if you've allowed it.

If you turn it on in Axolo's Settings, Axolo also saves to Apple Health the foods you log (name, calories, protein, carbs, fat and fiber) and your finished workouts (type, title, start and end). Each saved item carries its time zone. Sets, reps and weights stay in Axolo. When you edit or delete one of these in Axolo, its copy in Apple Health changes too. Axolo keeps a small log in its database of what it sent, with no food names or amounts. Axolo doesn't read other apps' food or workouts from Apple Health. Once saved, this data is in Apple Health and handled under your Apple Health settings; turning the switch off stops new saves and leaves what's already there.

Apple Health data is used only to track your weight and to coach you, including your weekly calorie check-in. Body fat readings are stored with your weigh-ins for that purpose. It isn't sold, isn't used for advertising or marketing, and isn't used by Axolo to train AI models. It's shared only with the services that run this coaching, named below, which process it for Axolo. When the coach answers you, your weigh-ins can go to OpenAI, through Vercel AI Gateway, to write the reply. If you connect Claude or ChatGPT and ask about your weigh-ins, they go there as described below.

You can turn this off at any time in your iPhone's Settings under Privacy & Security > Health > Axolo, or choose what Axolo reads in its own Settings. Readings already copied to Axolo stay until you ask for them to be deleted. A weigh-in you delete in Apple Health stops counting in Axolo after it next syncs, and the copy stays hidden until you ask for your data to be deleted, which removes all of it.

How it's used

Your data is used only to show your own training, nutrition and health context in Axolo and to coach you. It isn't sold, isn't used for advertising and isn't used by Axolo to train AI models.

Connecting Claude or ChatGPT

You can connect Axolo to Claude, made by Anthropic, or ChatGPT, made by OpenAI. Nothing is shared until you sign in on Axolo's approval page and approve the connection. That page lists what the connection reads and changes before you agree.

Once connected, Claude or ChatGPT can request this data when you ask it something about your training:

Only the data needed to answer each request is sent. Once Claude or ChatGPT receives it, it becomes part of that conversation and is handled under Anthropic's privacy policy or OpenAI's privacy policy and your settings there, including whether conversations are used to improve their models.

When you ask, Claude or ChatGPT can also create, edit or delete routines, edit or start your training phase, and log or correct meals. The words you use to describe a meal go to OpenAI, through Vercel AI Gateway, to estimate its calories, the same as in the app's Nutrition chat. Axolo keeps each change with the version it replaced, so it can be undone.

Axolo doesn't receive your conversations, chat history or memory in Claude or ChatGPT. It receives only the request for each action, such as which routine to read or what to change.

To stop sharing, remove the Axolo connector in Claude or ChatGPT's settings. Its access then expires and isn't renewed.

Who data is shared with

Data is shared only with the services that run Axolo or that you choose to connect:

Storage and security

Data is stored in a private Supabase database that only your own sign-in can read. Access tokens for Google and for the Claude and ChatGPT connection are checked and kept server-side. Server logs record which action ran and whether it worked, not your data.

Google API limited use

Axolo's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including its Limited Use requirements. Fitbit data goes to Claude or ChatGPT only after you approve that connection, and only to answer your own requests.

Keeping and deleting data

Your data, including the change history kept for Undo, is kept until you ask for it to be deleted. You can stop Axolo's Fitbit access at any time in your Google Account permissions, and stop the Claude or ChatGPT connection in that app's settings.

Not medical advice

Axolo doesn't diagnose or treat any condition.

Changes

If this policy changes what's shared or with whom, the date above changes, and the approval page lists any new sharing before you agree to it.
