## What you need to know

### How long should ecommerce customer data be retained?

Retain each data category only as long as its documented purpose, applicable legal duty, dispute need and security requirement justify. There is no universal ecommerce period.

### Should all customer data have the same retention period?

No. Orders, marketing choices, support tickets, security logs and inactive profiles serve different purposes and need separate schedules.

### What is a data-retention policy?

A data-retention policy defines categories, purposes, start triggers, periods, exceptions, deletion or anonymization methods, owners, and review evidence.

### How should merchants decide retention periods?

Start with purpose and legal or contractual requirements, assess customer and security risk, document the period and review it when practices or rules change.

### Should inactive customer accounts be retained forever?

Usually not without a continuing documented need. Set inactivity review and deletion or anonymization rules while preserving required transaction records separately.

### How should legal/accounting requirements affect retention?

Validated tax, accounting, fraud, dispute, and other obligations may require selected records for defined periods. Keep only necessary fields and restrict their use.

### What happens when retention requirements conflict with deletion requests?

Identify which records are legally required, restrict and retain only that portion, delete other eligible data, and explain the outcome and basis through the request process.

### A quick store check

Assign a retention period, trigger, deletion method, exception, and owner to every customer-data category.

## Frequently asked questions

### When does a retention period begin?

Define a trigger for each category, such as order completion, account closure, consent withdrawal or case resolution.

### Can backups use a different deletion schedule?

Yes, when justified and protected, but document expiry and prevent restored data from returning to active use improperly.
