Common questions

How does KERN work?

KERN brings together three practices: reflecting, meditating and manifesting. In conversation you recognize what moves you and what holds you back. In meditation you internalize new perspectives. In manifestation you see what is changing for you. Courses guide you through it step by step.

In the app, on Home under Wissen (Knowledge), you'll find the video "KERN in einer Minute" (KERN in one minute) and the article "Wie KERN funktioniert" (How KERN works).

What does KERN cost?

The download is free. Without a subscription you get:

• the first course "Dein Einstieg" (Your start, 7 days)
• the meditations Body Scan, Atemfokus (breath focus) and Lampenfieber (stage fright). Depending on your topic, your first course unlocks one more meditation.
• a limited number of reflections and perspectives

KERN Premium opens all meditations, all further courses and more room for your reflections. It costs €9.99 per month or €79 per year. Prices may differ in other countries.

How do I cancel my subscription?

Subscriptions run through Apple. You can cancel any time in your iPhone settings: tap your name at the top, then Subscriptions → KERN. Premium stays active until the end of the period you paid for.

"Konto löschen" (Delete account) in KERN does not end a subscription. Please cancel it with Apple first.

I bought Premium but don't see it

In KERN, open a meditation that is still locked and tap Käufe wiederherstellen (Restore purchases) at the bottom. Make sure your iPhone is signed in with the same Apple ID you used to buy. If that doesn't help, write to us.

Is my data safe?

You start anonymously, without a name and without an email address. An encrypted cloud backup is on by default. During setup, and any time in the settings, you choose where your content lives:

• Cloud-Backup (recommended): Your content is encrypted on your iPhone before it reaches our servers in Frankfurt. Only your device can read it, we can't. Your iCloud Keychain keeps the key.
• Only on this device: Your content stays on your iPhone. If you lose the device, it can't be restored.

You can switch any time: Einstellungen (Settings) → App-Einstellungen (App settings) → Daten & Privatsphäre (Data & privacy) → Cloud-Backup.

When KERN replies to you, the text it needs goes to Anthropic's AI without your identifier. According to Anthropic, it isn't used for training. To improve KERN, we count pseudonymously how the app is used, for example how many meditations are played. We never see what you write. No ads, no selling of data. All the details are in the Privacy Policy.

I have a new iPhone. How do I get my data back?

This works if three things are true: your Cloud-Backup is on, your account is secured with Apple (Einstellungen → Account) and your iCloud Keychain is active. Then, on the first start on your new iPhone, tap Mit Apple anmelden (Sign in with Apple) and your content comes back.

Without iCloud Keychain you need your backup key. Export it beforehand under Einstellungen → Sicherheit (Security) → Schlüssel sichern (Back up key), for example to your password manager.

How do I delete my account?

At the very bottom of the settings: Konto löschen (Delete account). After you confirm, we delete your account with all content, on your iPhone and in the cloud, including a link to Apple. This can't be undone. Please cancel a running subscription with Apple first.

Does KERN work offline?

Partly.

• Without internet: listen to meditations, look at your history and your insights, internalize your perspectives
• With internet: conversations and reflections, formulating new perspectives, reviews, the personal texts in your courses, and the backup

Who voices the meditations?

The core meditations in KERN come with a male and a female voice. Both are voice remixes of Dennis and Karline Lisk. This lets KERN offer many meditations in several lengths. The personal meditations are voiced in person by Denyo/Dennis and guests.

Is KERN available in English or for Android?

Right now KERN is available in German, for iPhone and iPad. English and an Android version are planned.

The app crashes or a meditation won't load

Please try:

1. Close KERN fully and reopen it
2. Restart your iPhone
3. If that doesn't help, write to hello@getkern.app with your iPhone model, your iOS version and your KERN version (shown at the very bottom of the settings). Briefly describe what you tapped and what happened next. That helps us a lot.

A reply from KERN doesn't fit

KERN uses Claude by Anthropic for its replies, and we keep working on making them fit you well. If a reply feels off, write to us what it was about and what came back. We can't see your conversations, so your description helps us. Only share what you want to share.

"Sign in with Apple" doesn't work

1. In your iPhone settings, tap your name at the top and check that you're signed in with your Apple ID
2. Close KERN fully and reopen it

If that doesn't help, write to hello@getkern.app.

I have an idea or a wish

Gladly. We read every message ourselves. Write to hello@getkern.app what you'd like and how it would help you.
