# The subscribe page

Every subscribe calendar gets its own page at

```
https://app.kalender-sync.de/subscribe/cal_XXXXXXXXXXXX
```

You can link to it, print it as a QR code or share it in newsletters. The [button for your website](https://docs.kalender-sync.de/en/abo-kalender/button/) also leads visitors there when they pick "Other app".

## What visitors see

- **Banner, logo and name** of your calendar, with the description below. → [Branding](https://docs.kalender-sync.de/en/abo-kalender/branding/)
- **Organizer** with a link to your website and, if set, a contact link by email.
- **Upcoming events**, if you allow it: title, date, time, location and a short description. The page shows events of the next twelve months, at most 50. Times are shown in the calendar's time zone; visitors in another time zone can switch to their own.
- **The "Subscribe to calendar" button** with the choice of calendar app.
- **Sharing:** links for WhatsApp, Facebook, LinkedIn, X and email, the device's share menu (where available) and a QR code drawn in the browser.
- A short explanation of what subscribing means, and the line "We don't record who subscribes."
- A **"Report this page"** link in case someone wants to report abuse.

The page appears in the language you set for the calendar (English or German).

## Supported calendar apps

The menu lists:

| Entry | What happens |
|---|---|
| Apple Calendar | Opens the subscription dialog on iPhone, iPad or Mac (`webcal://`). |
| Google Calendar | Opens Google Calendar in the browser with the subscription. |
| Microsoft 365 | Opens Outlook on the web for work and school accounts. |
| Outlook.com | Opens Outlook on the web for personal Microsoft accounts. |
| Outlook (desktop) | Opens the installed Outlook app (`webcal://`). |
| Other app | Shows the feed link to copy, for any app that can subscribe to a calendar by URL. |

The page moves the app that fits the visitor's device to the top, for example Apple Calendar on an iPhone.

## Privacy on the subscribe page

- **No cookie banner, no trackers.** The page only loads from our own domain. The share buttons are plain links; the QR code is drawn in the browser.
- **We don't record who subscribes.** Every subscription gets its own feed link so we can count how many calendar apps fetch the calendar. We store no IP address and no user agent for it.
- If a visitor already subscribed, the page points that out. This information lives only in the visitor's browser (localStorage), not with us.
- Subscribe pages are **not indexable** by search engines (`noindex`). Visitors arrive through your website, your button or your links.

## Sandbox calendars

Calendars created with a sandbox key show a "Test calendar" note at the top of the subscribe page. In the feed their name starts with `[TEST]`. That way nobody mistakes a test calendar for the real one. → [Plans and limits](https://docs.kalender-sync.de/en/abo-kalender/tarife/)

## When a calendar is deleted

When you delete a subscribe calendar, its subscribe page goes offline. The feed keeps serving an empty calendar for 30 days, with a note that the publisher removed it. That way the events disappear for existing subscribers too. After that the feed answers `410 Gone`.
