A question about your account, your subscription, the Apple Watch or your data? The most common answers are here, and you can always reach us by email.

support@kratheos.com — we usually reply within 2 business days. For a question about your account, write from the email address you use to sign in.
Account and sign-in
How do I sign in?
Kratheos uses “Sign in with Apple” or “Continue with Google”: no password to remember. With Apple, you can hide your email address; our emails then go through Apple’s relay address.
I changed phones, how do I get my data back?
Install Kratheos on the new phone and sign in with the same Apple or Google account: your plan, your history and your conversation with the coach are kept on our servers.
Subscription
What is free?
Everything you do yourself is free: creating workouts and a full plan (recurring sessions included), editing, moving or cancelling them, free workouts, training on your phone and Apple Watch, history, charts, badges, Apple Health or Health Connect import, favourite routes, exercise sheets, progress photos and calendar export. Onboarding with the coach, the preview of the plan it proposes and a few messages are free too. The Premium subscription unlocks the automation: the AI coach with no message limit, generating and starting its plan, automatic progression and adaptation, the proactive coach and its tones. The price is shown in the app before any purchase.
How do I manage or cancel my subscription on iPhone?
Open Settings › your name › Subscriptions › Kratheos, then tap “Cancel Subscription”. You can also go through the App Store › your profile picture › Subscriptions.
Cancellation takes effect at the end of the period already paid for. Deleting the app or your Kratheos account does not cancel the subscription.
How do I manage or cancel my subscription on Android?
Open Google Play › your profile picture › Payments & subscriptions › Subscriptions › Kratheos, then tap “Cancel subscription”.
Cancellation takes effect at the end of the period already paid for.
How do I get a refund?
Payments are collected by Apple or Google, who handle refunds under their own rules: at reportaproblem.apple.com for the App Store, or from your Google Play order history. Write to us if you run into any trouble, we’ll help.
I changed devices, how do I get my subscription back?
Sign in with the same Kratheos account. A “Restore purchases” button will be available on the Premium screen as soon as in-app subscriptions open.
Apple Watch and Health
How do I install Kratheos on my Apple Watch?
On your iPhone, open the Watch app › My Watch, scroll down to “Available Apps” and tap “Install” next to Kratheos. Workouts started on your iPhone can then start directly on the watch.
Which Health data does Kratheos use?
During a workout on the watch: heart rate, active calories, distance and GPS route outdoors. The completed workout is saved to the Health app.
You can change these permissions at any time in Settings › Health › Data Access & Devices › Kratheos.
My data
How do I get a copy of all my data?
In the app: Profile › Account › Export my data. You receive a ZIP archive (JSON, CSV for spreadsheets, routes as GPX and GeoJSON), available for 7 days. One export every 24 hours.
Is my data sold or used for advertising?
No, never. The coach relies on an artificial intelligence provider that processes your messages to answer you, without using them to train its models. All the details are in the privacy policy.
Delete my account
How do I delete my account?
In the app: Profile › Account › Delete my account. Without the app: from the “Delete my account” page of this website, with your account’s email address.
Deletion happens 7 days later: until then, you can cancel it from the link received by email or by signing in again. Remember to cancel your subscription in the store.
