Delete SNAP Post Meta

Hi,

I have thousands of posts on my WP site, and I can see that SNAP has several post meta entries on each post. Is it save to delete those post metas to clean up my database? Since I won’t use them to repost or import comments from my old posts anymore.

I really appreciate if you could add a feature to clean database from old post meta entries. Let say it has an option to clean SNAP post meta from last week, month or last year posts.

Regards,
