Common questions

How does KERN work?

KERN guides you through three practices - Reflect, Meditate, Manifest. You recognize blocks within yourself, meditate with a goal, and anchor new perspectives and behaviors. A full explanation is in the app: Home → 🪨 The Method.

Is my data safe?

By default your data lives only on your iPhone. If you enabled cloud backup, it's mirrored encrypted on EU servers in Frankfurt. We don't sell data, use no tracking, train no AI on your content. Full explanation: Privacy Policy.

What does KERN cost?

KERN is free during beta. When we introduce premium features later, we'll tell you well in advance - and there will be a generous free core.

How do I delete my data?

In the app: Settings → Account → Delete all data.

That removes everything - local on your iPhone and (if cloud backup was on) in the cloud too. This action cannot be undone.

If you want to keep the account but switch between cloud and local-only: Settings → Data & Privacy → Cloud Backup.

The app crashes / a meditation won't load

Sorry about that. Try:

1. Close the app fully and reopen
2. If that doesn't help: restart your iPhone
3. If it still happens: write us with your iPhone model and iOS version at hello@getkern.app. If you can describe the exact error (what did you tap? what happened next?), it helps us fix it fast.

The AI responses are weird / not helpful

KERN uses Claude (Anthropic) for AI mirrors. We continuously tune the prompts. If a specific response feels off, send us the scenario (what did you say? what came back?) at hello@getkern.app - that helps us improve the system.

Does KERN work offline?

Partially:

• Works offline: listening to meditations, viewing history, browsing insights, reading affirmations
• Needs internet: AI mirrors (Mirror, reflection analysis, generating new affirmations), cloud backup

If you're offline and need an AI function, the app shows a notice. Your inputs aren't lost - try again later when online.

How do I switch language / voice?

Settings → Language (Deutsch / English)
Settings → Voice (male / female, currently only German fully supported)

Apple Sign-In isn't working

Sometimes Apple has a timing issue. Try:

1. iPhone Settings → Your name at the top → Apple ID → sign out and back in briefly
2. Restart KERN

If it still doesn't work: hello@getkern.app - we'll help.

How do I cancel my subscription?

We don't currently have subscriptions (beta phase). When premium arrives, management goes through iPhone Settings → Your name → Subscriptions.

I have an idea / a wish

Love to hear it. We read every feedback email ourselves. hello@getkern.app - describe what you need, why it helps you, and we add it to the roadmap memo.
