No - client sessions are not recorded or filmed.
The only possible exception to this is if you have specifically consented for your session to be recorded to aid a therapist in meeting a training requirement, however, this would have been discussed with you in detail in advance of any recording taking place and is generally not something offered or organised via the Harley Therapy Platform.
Your therapist will usually take clinical notes during sessions - this is a standard process that helps therapists keep track of important points discussed during your sessions and the progress you make. You can request to view your clinic notes by contacting your therapist directly to request a copy.
