How do I cancel membership of Apple community

Signing up to participate in Apple Support Communities is not really a membership.

You can stop using the site, and that is the end of it. You don’t even have to say “bye”.

Anything that you have added to this site, is now part of the site’s archive, for as long as Apple wishes to keep it.

Also see the terms and conditions for using this forum site, in particular § B-10.

If you receive email communications for site activity, that you do not (or no longer) wish to receive, then you can turn off options for that in your user profile preferences.

For scrubbing more of your site presence, if needed, please email the site administrators. See § A-13 of the terms.
