You asked Meta to delete the data Halka received from your Instagram account. This page shows where that request stands.
Everything Halka received from that Instagram account: the account connection, the username and profile picture, the access tokens, and the records of the posts published to that account. Videos you uploaded to Halka yourself are not Instagram data and stay in your Halka account until you delete them or close it.
To close your whole Halka account, sign in and use "Close your account" on the Settings screen. You can also write to us.
