# Message retention policy
{!owner-only.md!}
By default, Zulip stores messages indefinitely, allowing full-text
search of your complete history.
Zulip supports configuring both a global organization-level message
retention policy, as well as retention policies for individual
streams. These policies control how many days a message is stored
before being automatically deleted (the default being forever).
Zulip's system supports:
* Setting an organization-level retention policy, which applies to
all private messages and all streams without a specific policy.
* Setting a retention policy for individual streams, which overrides
the organization-level policy for that stream. This can be used to
just delete messages on specific streams, to only retain messages
forever on specific streams, or just to have a different retention
period.
In Zulip Cloud, message retention policies are available on the Zulip
Cloud Standard and Zulip Cloud Plus [plans](https://zulip.com/plans),
as well as for the hundreds of communities with sponsored Cloud
Standard hosting.

## Important details
* Retention policies are processed in a daily job; so changes in the
policy won't have any effect until the next time the daily job runs.
* Deleted messages are preserved temporarily in a special archive. So
if you discover a misconfiguration accidentally deleted content you
meant to preserve, contact Zulip support promptly for assistance with
restoration. See the [deletion
documentation](/help/edit-or-delete-a-message#how-deletion-works) for
more details on precisely how message deletion works in Zulip.
