OurFamilyWizard (OFW) Headquartered in Minneapolis, MN, does not provide a way for you to delete your data and protect you and your families privacy.
After I reviewed OFW's policies and procedures on their website, I emailed their support directly as I have done in the past for other companies, to request them to delete my account and the data within. I informed them that I do not have any pending legal reason that they would need to hold onto the data and offered to sign a legal affidavit stating such as well. They refused to comply with my request. Didn't ask to verify my identity, or anything of reasonable path of confirming my identity either.
Also, their tool does not offer Multifactor Authentication, Passwordless auth tokens, or SMS push, email push tokens, etc to validate your account. This is a big problem if your coparent is allowing other people to sign in as them and send you responses (Which happened to me.). My coparent's account had 4x the number of usual logins.
As an individual that works in the cyber world; a company that won't comply with a deletion request that doesn't have a legal reason to resist is very alarming and concerning for me.
If you live in a state that provides data deletion protections, you may need to seek legal assistance and take them to court.
