Our commitment to non-hijacking cashback

Last updated: 2026-07-26

The short version

Sift's cashback model is opt-in and non-intercepting: we never overwrite an attribution that someone else set, we never claim commissions we did not earn, and we never run our script on a page until you choose to. We built it as the direct opposite of the hijacking behavior that landed other tools in court.

We never overwrite your existing affiliate IDs

If you arrived at a retailer through another cashback link, a shopping portal, your bank's rewards page, or a loyalty program, Sift leaves that attribution exactly as you set it. Sift does not modify URL parameters, cookies, or document.referrer on the retailer's own pages.

Sift in particular will not touch:

Existing ?aff= parameters already in the URL.
Affiliate cookies set by other cashback tools, such as cj, rakuten, or impact.

We never claim commissions earned elsewhere

Sift only earns a commission when our code is the proven last touch and you actively applied it. We do not retroactively register attribution against a transaction whose affiliate was already set by another tool, by the retailer, or by your card issuer's shopping portal.

Scripts run only when you opt in

Sift's content script is dormant on install. It activates only on supported cart and checkout pages, and the "Apply Best" action is a deliberate click that re-runs Sift's own code path against the page in front of you. There is no silent injection on every site you visit and no background DOM mutation away from the checkout.

For the full details on what the extension does and does not collect, see our Privacy Policy.

Frequently asked questions

How is Sift different from Honey?

Sift detects and tests coupon codes at the checkout step and surfaces the best one — that part of the experience looks similar, and that is what the user sees. It does not overwrite existing affiliate IDs in the URL or in cookies, it does not claim commissions earned by another affiliate, and it does not inject anything into a page you have not opted into. Those four behaviors are exactly the ones at issue in the recent Honey / Capital One litigation and FTC class actions, and Sift is built to avoid every one of them.

Does Sift replace my existing cashback link?

No. Leave Rakuten, TopCashback, your bank's shopping portal, or any other cashback link in place — Sift runs alongside them and will not overwrite the attribution they set. You keep the commission they would have earned.

Will my Amazon or credit-card portal rewards still work?

Yes. Sift does not modify the URL parameters or cookies that Amazon Associates, Chase, Amex, Capital One Shopping, or any card-issuer rewards portal depend on, and it does not inject into those checkouts. If you arrived through a portal link, that portal keeps the attribution.

How do I disable Sift on a specific store?

Right-click the Sift icon in your Chrome toolbar → "This can read and change site data" → toggle the store off. Chrome's per-site extension permissions let you keep Sift on everywhere else. To uninstall entirely, use "Remove from Chrome" — the support page covers that in full.
