Give your practitioners a number to call and choose who is notified when one of them presses Emergency — including people who do not have a Klasly account.
Go to Settings → Messages and find "Therapist communication". Everything below is on that one card.
Enter the number a practitioner should reach in an emergency — usually your mobile rather than the front desk. It appears as a one-tap call on every appointment they open. If you leave it empty, they reach your studio's main number instead, and the card tells you that is what is happening.
Under "Alert recipients": you as owner are always on and cannot be removed. Each manager has a switch — turn off anyone who could not act on a safety call at night. Then add any extra email addresses: these do not need a Klasly account, so a personal inbox, a partner, or someone outside the studio all work.
When a practitioner presses Emergency, everyone on that list is emailed and pushed immediately, and a red banner appears on your dashboard. The banner stays until someone marks it resolved — see "Respond to a home-visit safety alert" for what to do when one arrives.
