Get to know us

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:

  • Schedule and track doctor visits, therapies, and wellness activities
  • Set medication reminders, including refill alerts
  • Keep personal notes with instructions, results, or lifestyle recommendations
  • View your full healthcare plan in a monthly calendar
  • Get reminders for upcoming appointments up to 30 days ahead
  • Manage care for your loved ones with up to 5 additional profiles
  • Use the app completely offline with no internet required

Privacy First

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.

Our Mission

We built Health Calendar to make health management simple, reliable, and stress-free for everyone, no matter your age or technical experience.

Frequently asked questions

Everything you need to know about Health Calendar — from privacy to medications, family profiles and offline use.

Getting Started

What is Health Calendar?+

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.

Is Health Calendar really free?+

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.

What's the difference between Free and Premium?+

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.

On which devices can I use the app?+

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.

How do I get started after installing?+

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.

In which languages is the app available?+

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.

Privacy & Security

Do you collect or use my email or any personal data?+

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.

Where is my health data stored?+

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.

Is the app GDPR compliant?+

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.

What happens to my data if I uninstall the app?+

Uninstalling deletes all locally stored data permanently. We strongly recommend exporting or backing up important information before removing the app.

Can my data be hacked or leaked online?+

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.).

Medications & Refills

Will I receive reminders for my medications?+

Yes. The app sends timely local notifications for every medication you schedule, with customizable times and frequency (daily, specific days, intervals).

Can I set refill reminders?+

Yes. You can set optional refill alerts so you're notified before your medication runs out — helping you avoid missed doses.

Can I track multiple medications at once?+

Absolutely. You can add as many medications as you need, each with its own dose, frequency, notes and refill schedule.

Can I add notes about side effects or instructions?+

Yes. Each medication and appointment supports free-text notes for instructions, side effects, dosages, doctor remarks or anything else relevant.

Appointments & Therapies

How far in advance can I schedule appointments?+

You can schedule appointments as far ahead as you like. The app will send reminders for upcoming appointments up to 30 days in advance.

What kind of therapies can I organize in the app?+

Any type of recurring therapy — rehabilitation, physiotherapy, psychotherapy, wellness routines, ongoing treatments — can be scheduled with custom frequency and notes.

Can I view my full schedule at a glance?+

Yes. The monthly calendar gives you a complete overview of all appointments, medications and therapies, color-coded for clarity.

Can I store test results or doctor instructions?+

Yes. Personal notes can be attached to any event, making it easy to keep test results, instructions or lifestyle recommendations together with the relevant appointment.

Family & Multiple Profiles

Can I manage health for my whole family?+

Yes. Each user can create up to 5 additional profiles — perfect for children, partners, elderly parents or anyone in your care who doesn't use a smartphone.

Are profiles kept separate?+

Yes. Each profile has its own appointments, medications, therapies and notes, so nothing gets mixed up between family members.

Can I switch quickly between profiles?+

Yes. Switching profiles takes a single tap, and reminders are clearly tagged with the correct person.

Notifications & Offline Use

Do I need an internet connection to use the app?+

No. Health Calendar works completely offline. All your data is stored locally and is accessible anytime, anywhere — no internet required.

Will reminders still work without internet?+

Yes. All reminders are local notifications scheduled directly on your device, so they work even in airplane mode or without signal.

Can I customize notification sounds and times?+

Yes. You can set the time of each reminder and use your device's notification settings for sound, vibration and Do Not Disturb behavior.

Ease of Use

Can I use the app even if I'm not tech-savvy?+

Definitely. Health Calendar is designed with simplicity in mind. The clean, large-text interface makes it easy for users of all ages — including older adults — to navigate and manage their health.

Does the app support dark mode?+

Yes. The app follows your device's light/dark mode preference for comfortable use day and night.

Is it accessible for users with vision difficulties?+

The app uses high-contrast colors, readable fonts and respects system accessibility settings such as larger text sizes.

Support & Feedback

How can I contact support or report a bug?+

Use the contact form on our website — your message comes straight to our team email and we usually reply within 1–2 business days.

Can I suggest new features?+

Absolutely. We build the app with our users — every suggestion is read by the team and many features have come directly from user feedback.
