Permanent Data Deletion With No Confirmation or Undo
3.3.4 — Error Prevention (Legal, Financial, Data)
Scenario
Setting
A grocery delivery app's shopping cart
What’s wrong
Deleting user-controllable data permanently with no confirmation and no recovery.
Example
A grocery delivery app's shopping cart shows the problem clearly: deleting user-controllable data permanently with no confirmation and no recovery.
Why it matters
Everyone in legal, financial, or data-changing flows — especially people prone to input mistakes. In this case (a grocery delivery app's shopping cart), they have to guess at the correct format.
How to test
Delete user-controllable data: if there's no confirmation prompt and no way to recover afterward, it fails.
How to fix
The submission must be reversible, checked with a chance to correct, or confirmed through an editable review step.
Outcome
Once corrected, a grocery delivery app's shopping cart lets them complete the form without guessing.
Who is affected
Everyone in legal, financial, or data-changing flows — especially people prone to input mistakes.
