Privacy notice · Updated August 16, 2026

Your collection stays yours.

Coin photos

CoinWow uploads the obverse and reverse only when remote analysis is needed. Raw server-side photos expire within 24 hours and should be deleted sooner when analysis no longer needs them. Photo metadata is removed before upload.

Your collection

Saved coins and collection details stay on your device. CoinWow does not offer account sync in this version.

Product improvement

Raw scan photos are not kept for training unless you later choose a separate, plain-language opt-in. Identification details, quality signals, and corrections may improve the service when they do not include the raw photos.

CoinWow counts a small set of app actions, such as starting or finishing a scan, saving a result, and viewing or choosing a plan. These counts include the app version, language, outcome, and day. They do not include photos, coin details, collection notes, searches, purchase records, account IDs, or device IDs. CoinWow does not use them for ads or tracking.

Listings and referrals

Current listings open on the seller’s site. A clearly marked link may earn CoinWow a commission after that partner approves the placement. Scan photos, collection records, and device or account identifiers are not added to affiliate links.
