I do not think T's are allowed to record without client consent except perhaps forensic T's. I would be ok with my T recording, but if she did, I would also record. I'd also need to know how the recordings were to be stored - I would require a strong security setup if they were to be stored digitally on a computer or hard drive, rather than on separate physical tapes. I also would not consent to anything that involved them being stored or backed up to the cloud. Ideally, they would be stored on a separate drive (HDD or USB drive) and encrypted.
