Mercari Seller Pro FAQ

Does it post or relist for me?

No. Mercari Seller Pro fills in Mercari's own listing or edit form with a draft, comps, or a suggested price drop — you review it and click post or save yourself. It never posts, relists, or edits without that click.

Is this allowed on Mercari?

We don't automate actions or crawl Mercari on your behalf. The extension prepares drafts and suggestions on pages you already have open, and you act yourself on Mercari's own page for every post, edit, or price change. You're responsible for following Mercari's rules and terms of service.

Do I need to give you my Mercari password?

No. You log in to Mercari normally in your own browser. The extension never asks for or stores your credentials.

What happens if Mercari changes its page layout?

Every action goes through a selector registry with fallbacks. If Mercari changes something and every fallback misses, you get a selector-drift alert instead of a silent failure, and we ship a fix.
