The legal stuff, in plain English

Terms of service.

Last updated: May 2026
TL;DR
DUPED. is free to use. Don't break it. We point you to products but don't sell them — what happens after you click is between you and the seller. AI helps generate dupe suggestions; it's smart but not perfect. We're not liable if a "dupe" doesn't dupe.

01By using DUPED.

By visiting or using this site, you agree to these Terms. If you don't agree, please don't use the site. These Terms can change — we'll update the "Last updated" date at the top when they do. Continuing to use the site means accepting the new Terms.

These Terms work together with our Privacy Policy.

02What DUPED. is (and isn't)

DUPED. is a free affiliate-supported site that helps you find cheaper alternatives ("dupes") to popular branded products. We use AI to suggest similar items from Amazon and other retailers.

We are not:

03AI-generated content disclaimer

Some of the content on DUPED. is generated by AI — specifically the "why it works" reasoning for each dupe and the suggested product matches. AI is smart but not perfect. It can:

Always read the actual product page, reviews, and specs before buying. Don't rely on our AI summary alone. If something seems off, trust the source over us.

04Affiliate links & commissions

DUPED. is a participant in the Amazon Associates Program and may join other affiliate networks in the future. When you click certain links and make a purchase, we may earn a small commission at no extra cost to you. This is how we keep the site free.

This doesn't affect what we show you — the AI ranks dupes by actual fit, not by commission rate. But you should know the financial relationship exists. Full disclosure in our Privacy Policy.

05Brand names & trademarks

Brand names like Stanley, Apple, Dyson, Lululemon, and so on are used on this site solely for reference — to identify the original product you're looking for a dupe of. All trademarks remain the property of their respective owners.

Products we suggest as "dupes" are independent items made and sold by third parties. They are not affiliated with, endorsed by, or made by the original brand. We make no claim that they are equivalent in quality, durability, or performance.

06Rules for using the site

You agree not to:

We reserve the right to block access (by IP or other means) to anyone clearly abusing the site.

07Your Vault & saved data

The Vault is stored locally in your browser. We don't have a copy. We can't restore it if you clear your browser, switch devices, or lose access. It's a feature for you, by you, on your device.

Save important dupes elsewhere too (screenshot, bookmark, whatever) if they really matter.

08Third-party services

DUPED. relies on several third parties: Amazon, Google (Analytics, Firebase), Groq, and various product data APIs. Their services come with their own terms and outages. If Amazon's affiliate API has a bad day, our search won't return results. We can't be responsible for third-party downtime or policy changes that affect what the site can do.

09Disclaimers

DUPED. is provided "as is" and "as available." We don't guarantee:

10Limitation of liability

To the maximum extent allowed by law, DUPED. and anyone running it aren't liable for any indirect, incidental, or consequential damages arising from using (or not being able to use) the site. This includes — but isn't limited to — buying a "dupe" that disappointed you, having a third-party seller scam you, or your Vault data getting cleared.

If you buy a product and it's a dud, that's a refund issue with the seller (usually Amazon), not us.

Our total liability for anything connected to this site is capped at $0, since the site is free.

11Changes to these Terms

We can update these Terms at any time. Material changes will be reflected in the "Last updated" date at the top. For significant changes, we'll show a notice on the site. Continued use means you accept the new Terms.

12Governing law

These Terms are governed by the laws of the United States. Any disputes will be handled in US courts, with the specific jurisdiction determined by where DUPED. is operated from at the time of the dispute.

13Contact

This is a small project — there's no support team. For privacy questions, see the Privacy Policy. For other issues, a contact method will be added once the project is bigger.
