Delete old data automatically

> Another option that I would love is the ability for umami to auto-clear data after a week/month/other timeframe and only keep the recent amount of time. I primarily use umami for its real-time/short-term analytics and have no need for anything longer than that, therefore, would like to save space/database overhead in the long run with something like this.

As this request got buried in another issue that was already merged I'd like to come back to this and open a separate issue for this.

I too am only interested in data from the last 2 month.

I'd appreciate a possibility to automatically truncate all data that's older than a specified time range. This could be a simple cronjob that deletes old data once a day.
