If you decide that you don't want your Snapchat account anymore, you can always delete your account. To do so, however, you'll need to use the desktop version of the app, which means you'll need to know your login information.
Keep in mind that once you complete these steps, your Snapchat account won't be deleted right away; it'll be deactivated for 30 days, during which time you'll have the option to reactivate your account before it's permanently deleted. So, in case you change your mind, it's a good idea to have your password and username handy.
And if you want to grab your data from the app in addition to deleting your Snapchat account, be sure that you've that done before going through this process. Otherwise you may lose your pictures and videos.
How to delete your Snapchat account
When you're ready to delete your account, here's what you'll need to do:
1. Go to the Snapchat accounts portal and enter the username, or email address, and password associated with your account.
2. Click "Delete My Account."
3. Confirm your choice by selecting "Continue" (you may also have to re-enter your username and password if they aren't saved to autofill).
Your friends on Snapchat won't be able to contact you through your account once you've completed the deletion process. You'll have to make sure that you have some other contact information saved for them if you want to keep in touch.
If you decide to reactivate your account before 30 days have passed, you can do so by logging back into your account using your username and password. It may take up to 24 hours for your account to reactivate.
