Health apps that keep your data on your phone.
Mintlane builds small, focused Android and iOS apps for health problems that existing tools handle badly. Every app works without an account, stores its data locally in an encrypted database, and carries no ads or tracking SDKs.
Our apps
Small, focused apps for data that is nobody else's business. None of them needs a server to do its job, so none of them has one.
Exact alarms on Android and critical alerts on iOS make a dose reminder behave like an alarm clock. Drug interaction hints, allergy profile, adherence history and end-to-end encrypted caregiver sharing.
Period, symptom and mood tracking with no account and no cloud sync at all. Predictions stay framed as estimates, and reminders are discreet by default.
A short daily stage of mental maths, memory and logic puzzles on an endless hiking map. No account, no ads, works offline. The app is in German.

What "local-first" actually means here
The phrase gets used loosely. These are the specific commitments behind it.
- No account walls — nothing to register for, ever.
- No advertising SDKs and no analytics libraries in the apps.
- No selling, sharing or brokering of health data. There is no pipeline for it.
- No cloud backup of medication or cycle data, even as an opt-in.
- Health data lives in an AES-256 encrypted database on your device.
- Apps work fully offline, so a lost connection never costs you a reminder.
- Every permission the app requests is named and explained on its page.
- Export and delete your data yourself, without asking a support team.
A small studio.
A clear purpose.
Mintlane is an independent one-person mobile studio based in Germany. It builds small, focused apps for Android and iOS — each one solving a specific everyday problem that existing tools handle poorly.
Every app is free to use at its core, works without an account, and keeps your data on your device. The aim is to build things that are genuinely useful and honest about what they do — including honest about what they cannot do.
