If you are a California resident — or covered by a comparable law elsewhere — you can opt out of the "sale" or "sharing" of your personal information as those terms are defined by the CCPA/CPRA.
How to opt out
Email info@ohatech.net from the address associated with your account, with the subject line "Do Not Sell or Share My Personal Information". Mention the application it relates to if you know it.
You can also opt out at the level of the individual application — check the privacy policy of the application you use.
Exercising this right does not affect your subscription, and you do not need an account to make the request.
