Your health, your data

Many health apps ask you to create an account, upload your data to the cloud, and store everything on their servers. At Crono Care Coach it works differently. All your data stays on your own phone. No accounts, no cloud, no servers where your data is stored.

Why privacy is so important

Your chronic condition is personal. How tired you are, which activities you do, when you have setbacks - these are intimate details about your life. That information belongs to you, not to a company. You should be able to trust that this sensitive data is safe and remains private.

That's why Crono Care Coach is built with privacy as its foundation. There is no database with user data. There are no servers that can be hacked. There is no company that can see what you register. Everything stays local on your phone, encrypted by your own device's security.

You decide what you share

Sometimes you do want to share data - for example with your healthcare provider during a consultation. That's possible, but only if you want to. You can take screenshots of relevant graphs, or use the built-in export functions for overviews. But you do that consciously, at the moment that suits you. No one else has access to your data without your active choice to share it.

And that also applies to backups. Making backups is very important, because if you lose your 2-year activity history, that's more than just very annoying. That's why Crono Care Coach has an automatic backup. But you have to turn it on yourself. Either to your iCloud, or to another location (manually) that you trust.

No hidden agenda

Crono Care Coach makes money through subscriptions, not through your data. There is no advertising model where your data is interesting to third parties. There is no business model based on analyzing user behavior. The app does exactly what it promises: help you gain insight into your condition, without asking a price for it in the form of your privacy.

Privacy with new functionality

Privacy-first is not just how the app works now, but also a promise for the future. Every new feature that is added follows the same principle: you keep control over your data. If there are ever features that make data sharing possible - for example to send graphs directly to your healthcare provider, or participation in scientific research - that only happens with your explicit consent, at the moment you want it.

The core always remains the same: your data stays yours, and you determine what happens with it.

Privacy and functionality

Privacy-first doesn't mean the app works less well. All analyses, graphs and insights are calculated locally on your phone. Pattern recognition happens on your device. The app is fully functional without an internet connection. You get all the functionality of modern health apps, but without your data leaving the door.

This is how health apps should work: your data, your device, your control
