It is important to learn the effects of deleting your Instagram account before actually doing it. With your account deleted, your profile and content will cease to exist. Other people on the platform will not be able to find your account or look for your pictures.
Additionally, other account data will be deleted as well. These include all the likes and comments you have made with that account. As mentioned above, Instagram will still hold on to your data after you have deleted your account, but only up to 30 days. After the 30-day mark, Instagram will begin to delete your data, resulting in the permanent loss of some of your data.
Aside from the 30-day threshold, Instagram also notes that it can take up to 90 full days for the total deletion of a profile account. This means that retrieving an account after 30 days may still be possible, but it would likely have permanently lost some of its content.
It is important for you to consider these effects because you might want to simply deactivate your account instead if you still want to hold on to your personal data. Deactivating an account is almost like a temporary deletion, as the effects of deactivation are the same as deleting it, with the main difference of being able to reactivate the account at any time.
