LeakLock by TheDeki

Close the loopholes that quietly drain your margin.

LeakLock watches every order and refund in your Shopify store for five kinds of promo and return abuse, flags them with the money at stake, and can block repeat welcome-discount claims at checkout.

Welcome-discount reuse

Same buyer, new email. Caught by normalized email, phone and address.

Free-shipping gaming

Orders that cross the threshold, then return the add-on.

Serial returners

Customers whose return rate crosses your limit get tagged.

Self-referrals

Referral codes used by someone linked to another account.

Leaked codes

Private codes suddenly used by many strangers, with optional auto-disable.

Install

Install LeakLock from the Shopify App Store, then open it from your Shopify admin.
