# Profile & notifications

Everything personal is managed under **Settings → Account** and **→ Notifications**.

## Profile

- **Name** and industry can be changed any time — the name appears e.g. in invitations you send.
- **Language**: German or English, applies to the app and emails.
- **Email address**: currently **not changeable** — it's the anchor of your account that all sign-in methods hang off. If your address needs to change (e.g. job switch), [contact support](https://docs.kalender-sync.de/en/troubleshooting/contact-support/) and we'll find a solution. (→ [Known limitations](https://docs.kalender-sync.de/en/troubleshooting/known-limitations/))

## Notifications

| Email | Default | Recommendation |
| --- | --- | --- |
| **Sync errors** — when a sync persistently fails | on | leave on — otherwise you'll only notice problems in the calendar |
| **Weekly digest** *(coming soon)* | off | coming soon — the toggle is already there |

**System emails** (login codes, invitations, "please reconnect", billing emails) can't be unsubscribed — the product doesn't work without them.

**Newsletter & product updates** are separate: they only come with your consent (checkbox at sign-up) and every email has an unsubscribe link.
