## How to set it up

**Step 1: Create a Proton account**

Go to [proton.me](https://proton.me) and create a free account. You automatically get access to:
- Proton Mail (encrypted email)
- Proton Calendar (encrypted calendar)
- Proton Drive (encrypted cloud, 1 GB free)

No credit card required.

**Step 2: Open Proton Calendar**

Open [calendar.proton.me](https://calendar.proton.me) or use the app:
- iOS: [App Store](https://apps.apple.com/app/proton-calendar/id1514709943)
- Android: [Play Store](https://play.google.com/store/apps/details?id=me.proton.android.calendar)

**Step 3: Create your first event**

- Click **+ New event**
- Enter title, date, time
- Optional: description, reminders, repeats
- **Important:** All data is **encrypted locally** before being sent to Proton's servers

**Step 4: Import your calendar (optional)**

You can import your Google Calendar events:
- Open Google Calendar → Settings → Export (as .ics file)
- In Proton Calendar: **Settings** → **Import** → upload .ics file
- Your old events will be encrypted and imported

**Step 5: Sync across devices**

Proton Calendar syncs automatically via:
- Web browser
- iOS app
- Android app

All changes are encrypted in real-time.

**Step 6: Share calendars (optional)**

You can share calendars with other Proton users:
- Select calendar → **Settings** → **Share**
- Enter recipient's email address
- Choose permissions (view only / edit)
- Shared events remain **end-to-end encrypted**

## Why this helps

**1. Privacy:** Google reads your appointments for personalized ads. Proton **cannot read** your events (end-to-end encryption).

**2. No ads:** Proton shows no ads based on your appointments.

**3. Swiss privacy:** Proton is based in Switzerland (strict privacy laws).

**4. Open source:** Code is publicly auditable – no hidden trackers.

**5. Free:** Basic version is enough for most users (up to 3 calendars, unlimited events).
