# 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](/docs/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](/docs/getting-started/keyboard-shortcuts), feedback, and a demo-call link in one place (also at **Settings → Help & Support**).
