# Profile and studio details

> Your personal details, your timezone, and the studio identity on your invoices.

Two settings pages hold who you are: **Settings → Profile** (you) and **Settings → Studio** (your business). The studio details feed your invoice header, so they're worth filling in before you bill anyone.

## Profile

| Field                   | Notes                                                                                              |
| ----------------------- | -------------------------------------------------------------------------------------------------- |
| **Profile picture**     | JPG, PNG, or WEBP, up to 2MB, at least 400 × 400.                                                  |
| **First and last name** | Required.                                                                                          |
| **Email**               | Shown for reference; it's your sign-in email and isn't edited here.                                |
| **Phone**               | Optional.                                                                                          |
| **Timezone**            | Required. Detected from your browser the first time; every calendar time follows it (see below).   |
| **Sending address**     | The `@instructor.harnesscalendar.com` address your studio's emails come from. Shown for reference. |

### Your timezone drives every calendar time

Harness shows all times in your **studio timezone**, never your device's clock. That keeps your calendar and your students' emails consistent when you travel or a device is set wrong. If times ever look shifted by an hour or a few, this setting is the first thing to check.

## Studio

| Field              | Notes                                          |
| ------------------ | ---------------------------------------------- |
| **Studio name**    | Required. Appears on your invoices and emails. |
| **Website**        | Optional. Can appear in your invoice header.   |
| **Studio address** | Optional. Can appear in your invoice header.   |

Which of these actually print on an invoice is up to you: the header toggles live in [your invoicing defaults](/settings/invoicing-defaults).

## Make it yours

A few personal touches live in the account menu (your avatar in the sidebar):

* **Theme** cycles Light → Dark → System.
* **Give Feedback** sends a bug report or an idea straight to the Harness team.
* **Help & Support** collects the docs, the [keyboard shortcuts](/getting-started/keyboard-shortcuts), feedback, and a demo-call link in one place (also at **Settings → Help & Support**).
