Delete your DietLens account
In the app
Open Profile, then Delete my account, and confirm. Your account is deleted straight away and you are signed out on every phone.
What is deleted
Everything DietLens holds about you: your account, its link to your Google account (Google's id for you and your email address), and everything you saved. Encrypted backups of DietLens's database are kept for up to 90 days, so a deleted account can remain in them until they expire.
More about what DietLens collects is on the privacy page.
