Common questions

Which marketplaces does ShopLens support?

Etsy, eBay (including the UK site), Amazon (.com and .co.uk), and Walmart. Each marketplace gets its own search-page overlay and listing quality scorecard tuned to that site's page layout.

Does ShopLens estimate sales or revenue?

No — it never invents modeled sales numbers. Demand signals such as eBay sold counts or Amazon's "bought in past month" badge are read only when the marketplace itself prints them on the page, and every heuristic is labeled as an estimate.

Do I need an account to use ShopLens?

No. The free tier needs no signup at all, unlike leading marketplace research tools in this space, which typically charge a steep monthly fee and still require an account for their limited free tier.

What does Pro add?

Page-stated demand signals, a 0-100 competition estimate, CSV export of visible results, deeper keyword analysis (top 25 keywords plus phrases), and saved research history you can revisit later.

How does the Aegis Pro Pack unlock ShopLens?

Sign in to aegisfirma.com from any installed Aegis extension popup. The cookie-auth flow detects your active Pro Pack and unlocks Pro features instantly — no license key to copy or paste.

Where is my ShopLens data stored?

ShopLens stores everything in chrome.storage on your device. Your subscription record lives in our payment provider's account; we do not aggregate browsing or activity data.

Can I cancel ShopLens Pro anytime?

Yes — billing stops at the end of the current period. Pro features remain active until the period ends, then drop back to the free tier.

Why should I trust an extension I just heard of?

Aegis extensions never change ownership and never sell user data. We publish security audit results and ship MV3-native code so Chrome itself enforces the permissions we claim.
