OnlyCaly is a scheduling tool aimed directly at mental-health clinicians, marketed as free and HIPAA-friendly with privacy-first defaults (no calendar exposure, discreet event naming, therapy-specific intake forms). Built in Europe with a focus on reducing no-shows, it is a newer, narrower alternative to Acuity for therapists who want booking that respects the sensitivity of mental-health appointments. Confirm a signed BAA directly with the vendor before transmitting client PHI.
