Fix a typo or rename your studio from Settings → Account → Studio name. Your booking link stays the same unless you choose to change it.
Go to Settings → Account. The Studio name card is at the top. Type the new name (up to 120 characters) and press Save.
Everywhere at once: your dashboard, the booking page and widget, Klasly search, and every email sent from then on. Emails already sent keep the old name.
Your link (/b/your-studio) is not changed by a rename, so QR codes and links you have already printed or shared keep working. If you want a link that matches the new name, tick "Change it to /b/…" under the name before saving — the old link then stops working.
