We collect what the product needs and nothing more: your account details (name, email, profession), the specimens you pin to your board, and the quote requests you send to vendors. We use this to run your board, route your requests to the right vendor, and show you trade pricing where it applies.

We do not sell your data, and we do not share it with anyone beyond the vendors you explicitly request a quote from. You can ask us to export or delete your account data at any time.

Arch Array is a discovery and quoting layer, not a retailer of record — every material sold through the library is sold by its listed vendor, under that vendor's own commercial terms, delivery timelines and warranty.

Trade pricing shown to signed-in members reflects a discount off list price and is offered at the vendor's discretion. Misrepresenting your profession or verification status to obtain trade pricing may result in your account being suspended.

On the web, we use browser storage to keep you signed in, remember your board and recent searches, and remember chrome preferences like your last view mode. None of this is used for third-party advertising or cross-site tracking.
