Nothing lasts forever, and certainly not in the land of Snapchat, the app that first popularised the idea of photos, videos and messages that fade away after a certain number of seconds.
If you've had enough of this impermanence and want to switch to something a little more lasting, deleting and deactivating your Snapchat account isn't difficult to do, but you are going to open up a web browser - at the moment you can't actually delete your account from inside the apps for Android and iOS.
You also get a month between account deactivation and account deletion, in case you change your mind.
1. Visit the delete account page
The special Snapchat delete account support website will handle all of your Snapchat account deleting needs is , so fire up a web browser and type it in. You can use a browser app on your phone if you don't have access to a computer.
First of all you need to log in using your Snapchat credentials - if you've forgotten them (maybe that's why you're deleting your account) then click the 'Forgot your password?' link to get a reset link sent to your inbox.
This online login is only for deleting your account by the way, and you can't look at your trophies or snaps on the web.
2. Recover your username and password
If you've forgotten your username or the email address you registered with Snapchat you can find them both from inside the app. If you tap the ghost icon at the top of the capture screen your username appears (just below your real name) and you can tap the cog icon (top right) to see your email address and other account details.
Assuming you've got all your credentials ready one way or another, enter them into the login page, tick the captcha box to prove you're a real flesh and blood human being, and click the Log In button.
3. Make up your mind about deleting the Snapchat account
Snapchat gives you another chance to change your mind so take a moment and consider whether you can really live without the app in your life.
Note too the details about how the process works - as soon as you complete these steps, your Snapchat account is deactivated, which means other people won't be able to contact you through the app. Another 30 days after that, your Snapchat account is deleted forever, which means your details vanish for good.
Presuming you're happy to proceed, enter your username and password again (your browser might have remembered them for you) and click 'Continue'.
4. Check for confirmation
You're all done - your account is deactivated. You'll get a confirmation message sent to your registered email address from Team Snapchat explaining what happens next, and reminding you that you've got 30 days if you happen to change your mind.
Because everything is handled over the web, the process is the same whether you're using Snapchat on Android or iOS, but you'll want to remove the Snapchat app from your phone as well (you don't need to log out first).
On iOS, tap and hold the Snapchat app icon then press the cross symbol. On recent versions of Android, tap and hold the app icon and drag it up to the Uninstall button.
5. Changed your mind? Reactivate your Snapchat account
You can bring your Snapchat account back from digital death at any point over the 30-day window by logging back into the app. Your friends list should still be there too.
Launch Snapchat again and you'll notice you've been logged out, even if you didn't uninstall the app in the meantime. Tap Log In, enter your original details (your username might have been remembered for you), and then tap Log In again.
A message appears asking if you want to reactivate your account so tap Yes. Snapchat puts the wheels in motion and if you wait a few minutes then log in again you should be back in Snapchat business (you also get an email when your account is ready to use again).
