Privacy Policy

Data Collection

COINDEX does not collect personal information without your consent. We use anonymous analytics solely to improve the platform.

Photo Uploads

When you upload photos, all EXIF metadata is automatically stripped client-side in your browser before the image ever leaves your device. This includes GPS coordinates, device info, timestamps, camera settings, and owner information. We use a canvas redraw approach that guarantees complete metadata removal while preserving correct photo orientation.

We do not store IP addresses associated with uploads. Learn more about photo privacy.

Seller Storefronts

Sellers with a COINDEX storefront give us a notification email address during setup, and we store it in plain text on their seller record. This is the one place we hold an email address we can read: your account email is stored only as a one-way hash, which is why a storefront needs its address typed in separately. It is used only to tell a seller that a cart arrived, and it is deleted if seller access is removed.

Buyers need no account and give us nothing. A submitted cart stores the items, the total, and an optional note to the seller — no name, no contact details, and no payment information. We store a one-way hash of the submitting device's IP address, which we use only to rate-limit cart submissions and cannot reverse into an address.

COINDEX never handles payment for these sales. Buyers and sellers settle directly, in whatever channel they already use.

AI Training Data

Your photos are never used for AI training unless you explicitly opt in via your profile settings. All training data is anonymized and never linked to personal information.

Third Parties

We do not sell, trade, or transfer your data to third parties. Affiliate links may be used to support the platform.

Advertising

COINDEX no longer displays Google AdSense ads, and sets no Google advertising cookie. The site is funded by donations. Some outbound product links are affiliate links, including the eBay Partner Network, which may earn COINDEX a commission at no additional cost to you.
