# What happens to messages outside my data retention period?

Your **date picker is limited** to the end of your data retention window. By default, that’s **24 months**, meaning you can select any date up to 24 months in the past.

Messages beyond that period are **not deleted** — they remain stored in SEINō and can be accessed again if you **extend your data retention**.
