Security & privacy

Your data belongs to you

Stored in Frankfurt, AI only with consent and only in the EU, the vault end-to-end encrypted – and no ads. This is how LifeButler protects what you share.

Stored in the EU

All data is stored in data centres in Frankfurt, Germany (Google Cloud / Firebase, region europe-west3). The provider is CodeWorx UG (haftungsbeschränkt) from Augsburg – a German company subject to the GDPR.

Always encrypted in transit (TLS)
Sign in with Google or Apple – LifeButler doesn’t store a password of yours
Every group is sealed off: access rules on the server check every request

The vault: end-to-end encrypted

ID numbers, insurance details, bank details and passwords are encrypted on the phone before they’re stored. Only your devices hold the key – not even we can read the vault.

AES-256-GCM, with the key wrapped per device using X25519
Opens only with fingerprint or face – no PIN back door
New devices are approved by another adult or the recovery code
Access log, screenshot blocking, auto-lock after 3 minutes

Family vault

AI only with consent – and only in the EU

Smart Inbox, the butler and the AI meal planner are off until a group’s admins switch them on. Then Google Vertex AI (Gemini) processes documents and questions in the EU – not for training the models. Anthropic (Claude) only steps in during outages.

The vault and gift ideas are never sent to an AI
The butler respects roles: kids get no answers about money or health
AI suggestions only become entries once you confirm them
Smart search runs in Frankfurt

Ask your butler

Everyone sees only what suits them

Roles decide who sees what. This is enforced on the server, not just in the app.

Kids: lists, appointments, tasks, polls – but no money, documents, health records or vault
Guests such as babysitters: everyday things and emergency info – but no money, documents or vault
Gift ideas are invisible to the person they’re for

Frequently asked questions

Can LifeButler staff read my data?

Not the vault – it’s end-to-end encrypted and readable only on your devices. All other data is encrypted in transit and stored encrypted on the servers in Frankfurt.

What happens if I lose my phone?

Your data lives in your account, not just on the phone. For the vault, another adult in the group approves your new device – or you use your recovery code.

Is an AI trained on my documents?

No. The AI providers only process documents and questions to answer you and don’t use them for training.
