Terms of Service

Last updated: 2026-10-18

Who we are

Before You Buy — our browser extension and besidesguide.com — is operated by BesidesGuide LLC, a United States limited liability company (“we” or “us”). By installing the extension or using the site you agree to these terms.

What the extension does

On Sephora and Ulta product pages, the extension shows alternative products, what reviewers rate each one best for, and a link to our website comparison. Page matching and referral checks happen locally; the extension downloads a product index periodically and requests comparisons when the panel is open. Full details can open our website. Its first-party pause controls and the extension’s own-site helper retain referral protection across navigation and recheck it before opening a store link. We grant you a personal, non-transferable, revocable license to use it for your own shopping. Don’t reverse-engineer it to extract our data, resell it, or use it to build a competing dataset.

Information, not advice

What reviewers rate a product best for is a summary of public retailer reviews, presented in good faith. It is not a guarantee of how a product will work for you, and it is not medical or dermatological advice. Check ingredients and consult a professional if you have skin conditions or allergies.

Prices and availability

This version provides analysis without purchase links or affiliate attribution. Current prices and discounts are not quoted by Before You Buy in this version. Listing checks are point-in-time snapshots; store links do not guarantee that an item is in stock. Check the retailer’s page for current details. The price on the retailer’s own page at checkout is the one that applies.

Purchases happen at the retailer

When you click through, you leave Before You Buy. Your purchase, payment, shipping, returns and account are between you and the retailer, under the retailer’s terms. We are not a seller and are not affiliated with, sponsored by, or endorsed by Sephora or Ulta Beauty.

Affiliate links

In a future approved commercial version, if affiliate links are enabled and you buy after clicking, the retailer may pay us a commission, at no cost to you. Commission never changes which products we show or what we say about them. Affiliate links are only ever activated by your click; the extension does not apply coupons, rewrite links on retailer pages, or act in the background to generate affiliate attribution. If it recognizes another publisher’s referral parameters, it pauses recommendations on that store and suppresses links to it for the session and at least 30 minutes. See how we make money.

YouTube content

The comparison view shows publicly posted YouTube comments through the YouTube API Services. By using Before You Buy you agree to be bound by the YouTube Terms of Service. See our Privacy Policy and Google’s Privacy Policy.

Trademarks

Product, brand and retailer names are trademarks of their respective owners. We use them only to identify the products being compared; this does not imply endorsement, sponsorship, or affiliation.

Copyright

If you believe something we show infringes your rights, follow our DMCA process or email takedown@besidesguide.com.

Changes and termination

We may change or discontinue the extension or the site, or update these terms; the date above shows the latest version. You can stop using Before You Buy at any time by uninstalling the extension.

Disclaimer and limitation of liability

Before You Buy is provided “as is” without warranties of any kind. To the maximum extent permitted by law, BesidesGuide LLC is not liable for any direct, indirect, incidental, or consequential damages arising from your use of Before You Buy or from purchases made at a retailer.

Governing law and venue

These terms are governed by the laws of the State of California, United States, without regard to its conflict of law provisions. Any dispute arising out of these terms or your use of Before You Buy shall be brought exclusively in the state or federal courts located in California, and you consent to their personal jurisdiction.
