You can delete your biogr.id account at any time, directly from the biogr.id dashboard in WordPress. Deleting your account removes everything biogr.id holds for you:
This affects only the data cached on biogr.id — your Instagram account and the posts on it are untouched. If you only want to stop syncing without deleting anything, disconnect your Instagram account from Settings instead.
Only what’s needed to build and display your bio page:
To keep your bio page loading reliably, biogr.id caches your post images and your profile picture — the image links Instagram provides expire after a few days, which would otherwise leave your bio page showing broken images. biogr.id never accesses your direct messages, your password, or your Instagram login credentials.
