Data Retention Policy
What does data retention policy mean?
A data retention policy is an organization's documented set of rules for how long it keeps different types of data and what happens to that data, deletion, anonymization, or archiving, once the retention period ends. It applies to personal data, financial records, employee files, logs, and other business information.
How does a data retention policy work?
A data retention policy typically assigns a retention period to each category of data based on legal requirements, business needs, and risk tolerance. Once that period expires, the data is deleted, anonymized to remove identifying details, or moved to archival storage if there is a valid reason to keep it longer, such as a legal hold.
Most privacy laws do not set a single fixed retention period for all data. Instead, frameworks like GDPR and CCPA expect organizations to retain personal data only as long as necessary for the purpose it was originally collected, and to be able to explain that reasoning if asked. For the full framework, including a step-by-step process and standard retention periods by regulation, see Clym's guide to what a data retention policy is and how to build one.

Data retention policy vs. related terms
A data retention policy is often confused with a couple of closely related terms:
Data retention is the broader practice the policy governs: keeping data for a defined period before disposing of it.
Retention period is the specific length of time assigned to one category of data within the policy. See Clym's retention period glossary entry.
Data minimization is a separate principle about limiting what you collect in the first place, not how long you keep it. See data minimization.
Commonly asked questions
It is a written set of rules that says what data an organization keeps, for how long, and what happens to it once that time is up, whether that means deleting it, anonymizing it, or archiving it.
Requirements vary by law and industry. Many privacy regulations require organizations to disclose retention periods or the criteria used to set them, most commonly through a privacy policy, even where a fixed retention timeline is not mandated.
A retention period is one input inside a data retention policy: the specific length of time assigned to a single category of data. The policy is the full document that sets out retention periods, storage rules, and disposal procedures for every category an organization holds.
Responsibility is usually shared across legal, IT, and privacy or compliance teams, with one owner accountable for keeping the policy current and reviewed on a regular basis.
