Hi Kari, I think this is probably what you are looking for
Posts and comments that users make in Chatter are retained during the entire time that a customer's applicable org remains provisioned. We reserve the right to enforce limits on:
- The number of system-generated tracked feed updates. Currently tracked feed updates that are older than 45 days and have no likes or comments are deleted automatically. - The tracked feed updates no longer appear in the feed. However, if auditing is enabled for a tracked field, the audit history for that field is still available.
The number of email notifications that can be sent per org per hour.
