One app for you and your family's health. · Available on both Android and iOS — download today!
Your health, always organized.
At Health Calendar, we know how overwhelming it can be to manage healthcare in today's busy world. Doctor appointments, medications, therapies, tests, and notes often pile up without the right system in place.
That's why we created Health Calendar — a simple, intuitive, and complete health calendar app that keeps everything in one secure place.
With Health Calendar, you can:
Your privacy is our top priority. We never collect, store, or access personal data. Everything stays on your device, under your control — never uploaded or shared with anyone.
We built Health Calendar to make health management simple, reliable, and stress-free for everyone, no matter your age or technical experience.
Everything you need to know about Health Calendar — from privacy to medications, family profiles and offline use.
Health Calendar is a privacy-first mobile app that helps you and your family organize doctor appointments, medication schedules, therapies, refills and personal health notes — all in one clean monthly calendar that works 100% offline.
Yes. Health Calendar has a free plan that covers all the essentials — appointments, medication reminders, family profiles and full offline use. We also offer an optional Premium plan (monthly or yearly subscription) for users who want extra features. There are no ads and no surprise charges.
The Free plan includes everything you need to organize your health: unlimited appointments, medications, reminders, family profiles and offline access. Premium unlocks advanced features for power users — choose between a monthly or yearly subscription, with the yearly plan offering the best value.
Health Calendar is available on Android (Google Play) and iOS (App Store). It runs on phones and tablets and is optimized for both small and large screens.
Just open the app — no sign-up, no email, no account required. You can immediately add your first appointment, medication or note. Your data stays on your device.
Health Calendar is available in 9 languages: English, Greek, Spanish, Bulgarian, Russian, Arabic, Portuguese, German and French — making it accessible to users across Europe, the Middle East and beyond.
No. We do not collect, store or transmit any personal or medical data — not even your email address — unless you choose to contact us directly through our website.
Everything is stored locally on your device. Nothing is uploaded to a cloud, no analytics on health content is performed, and no third party can access it.
Yes, 100%. Because we don't collect personal data from inside the app, there is nothing to share, sell or leak. Our website also uses Google Consent Mode v2 with a cookie banner so you control any optional analytics.
Uninstalling deletes all locally stored data permanently. We strongly recommend exporting or backing up important information before removing the app.
Since data never leaves your device and is never sent to a server, there is no online database that could be hacked. Your security depends only on your device's own protection (PIN, biometrics, etc.).
