> How QuickWishlist attempts to obtain linked-page product details, and what those details mean.

## 1. URL safety check

Before fetching a source page, QuickWishlist verifies that the destination uses HTTP or HTTPS and resolves only to public internet addresses.

## 2. Deterministic extraction first

The extractor checks page metadata such as JSON-LD, Open Graph, microdata, embedded application data, and visible product signals. It also contains targeted fallbacks for several common commerce platforms.

## 3. Optional AI fallback

If deterministic data is incomplete and an OpenAI API key is configured, selected page signals may be sent to OpenAI to supplement or recover product fields.

## 4. Stored snapshot

The selected name, displayed price, thumbnail, and original URL are stored with the wishlist item. They are a snapshot, not a live retailer feed.

## 5. Owner review

Owners can correct the stored name, displayed price, notes, and URL. Buyers should verify price, availability, shipping, and product details on the linked source page.

## Interpretation and caveats

- QuickWishlist does not publish customer counts, market share, extraction-accuracy percentages, ranking scores, or performance benchmarks.
- The site does not publish testimonials, awards, or comparative performance claims.
- Prices shown inside user wishlists are user-editable snapshots from linked pages, not audited market data.

- Automatic extraction can be incomplete or wrong when a source blocks access, changes markup, localizes content, or exposes conflicting metadata.
- A stored price is display text, not a verified quote or live commerce feed.
- The linked source page remains authoritative for price, availability, shipping, and the purchase.
