RowCheck privacy policy

Last updated 21 October 2026. Publisher: MAW2IN (ceo@maw2in.com).

In short

RowCheck reads and checks your file inside the extension page. Nothing is uploaded to us or anyone else. RowCheck has no account system, shows no ads, and uses no analytics or tracking. MAW2IN does not sell, rent or share any data, and has no server that receives your browsing data.

Details

What is stored

Your column mappings and licence key, in local extension storage.

The only network call

The Pro key check with Gumroad (api.gumroad.com): the key and product ID only, when you activate it and about once a week after.

File never uploaded

Checked in the browser, exported back to your Downloads folder.

No tracking

No account, no ads, no analytics, no server of ours.

Payments

The Pro key is sold through Gumroad. Gumroad processes the payment and your e-mail address under its own privacy policy; MAW2IN receives the order details Gumroad provides to sellers (such as your e-mail address) to deliver the key and handle refunds.

Removing your data

Everything the extension stores lives in your browser profile. Removing the extension removes it. For anything related to a purchase, write to ceo@maw2in.com.
