Account Deletion

Deleting or anonymizing a user across every table and system.

Also known as: account deletion, delete account, account removal

Account deletion is a user’s request to remove their account and data — a common feature and, under privacy rules like GDPR, often a legal right. The mechanics are more involved than a DELETE: you must decide what’s removed, what’s retained, and how to handle data spread across many tables and systems.

request → grace period (reversible?) → delete/anonymize data → confirm

The design questions:

• Immediate or delayed? A grace period (or “deactivate then delete”) lets users recover from an accidental request and gives you time to cancel subscriptions, stop billing, etc.
• Hard delete or anonymize? Some data must actually go; other data (order history for tax, financial records) must be retained but can be anonymized.
• Cascade and references. The account’s data spans many tables and services; deletion must cover all of them (or orphaned data and broken references remain).
• Legal retention. Financial, legal and fraud-prevention obligations may require keeping some records for a period, even after “deletion”.

The classic mistakes:

• Deleting the user row and stopping there. Related records across tables/services are left behind, breaking referential integrity or leaving personal data. Map everything tied to the account.
• Deleting data you’re legally required to keep. Financial and legal records often must be retained; a blanket delete violates obligations. Distinguish erasable personal data from retainable records.
• No grace period or confirmation. An accidental click permanently destroys an account; a grace period and confirmation prevent that.
• Forgetting billing and subscriptions. Deleting an account without cancelling its subscription keeps charging the user. Cancel billing as part of deletion.
• Ignoring backups. Backups retain deleted data until they expire; your privacy handling must account for that (and say so).
• Missing third parties. Data sent to analytics, CRM, email providers, etc., must also be deleted/requested for deletion (see third-party integration).
• No audit of the deletion. Keep a record that deletion happened and when (without the deleted data) for compliance and support.
• Breaking referential integrity. A hard delete of a parent row can cascade-fail or orphan children; use soft delete or anonymization where references must survive.

How to implement it: define exactly what’s deleted vs anonymized vs retained; span every system; cancel billing; offer a grace period; run it as a robust background job; and record the deletion. It’s a routine feature with real legal weight — treat it as a careful, audited process, not a single DELETE. See audit columns.
