Privacy

sold4 (sold4.online) helps you photograph books and estimate used resale prices.

Photos

Book photos are sent to Google Gemini so we can read titles and covers. We do not keep original photos on our servers. After identification, the full-size image is deleted from your device; a small thumbnail can remain in your browser until you clear scans or site data.

Account

Sign-in is handled by Clerk. We receive your account id and email. Usage counts (photos and sold-price checks) are stored so we can enforce plan limits.

Book data

Titles, authors, ISBNs, and price ranges may be cached briefly to avoid repeat lookups. Your scan list lives in your browser unless you export CSV.
