Privacy Policy

Last updated: 2026-10-13Draft for review

Before publication, complete the privacy contact address and confirm service providers, cookies and retention periods.

Scope

This policy describes the handling of information associated with this website’s content, account access, collection management and security features. Third-party websites and services have their own privacy policies.

Information you provide

Account information includes your username, email address and registration invitation code. When using the collector dashboard, you may submit descriptions, images, certificate numbers, storage locations, purchase and sale records, contact details and expenses. Submit only information you are entitled to provide, and avoid including sensitive personal information in public content.

How information is used

Information supports account management, storage of submitted collection and transaction records, language preferences, login sessions, security verification and requests you initiate. Hosting and security services may process technical information associated with visits and sign-ins. The exact records depend on the services enabled.

Collections and public content

Content you choose to make public may be viewed by visitors. Collection visibility settings control public presentation on the site; they do not recall copies already saved by others, search-engine caches or directly accessible image files. Before uploading, check images for location metadata and other personal information.

Cookies and local storage

Cookies support sign-in and authentication, and a language preference cookie remembers your language choice. Browser local storage may also save interface preferences. You can clear or restrict this storage in your browser; blocking authentication cookies may prevent account features from working. Any additional cookies used by third-party plugins must be documented according to the actual configuration.

Account security and passkeys

Two-factor authentication, recovery codes and passkey features are supplied by the site’s security components. Keep recovery codes secure and do not publish authenticator secrets. With passkeys, fingerprint, face or device-unlock checks are handled by your device and credential services; the website receives the authentication result.

External links and services

Following external links or loading third-party embedded content may send your IP address, browser details and request information to the relevant service. Data handling by maps, image sources or security services depends on what is loaded. Before publication, the operator must identify the hosting, email, security, analytics and other providers actually used.

Retention and deletion

Retention periods for account and collection records, backups and security logs must reflect the site’s actual operation. Removing an image from a page may remove only its display copy; a media-library original or backup may remain. Specific retention periods and backup-deletion procedures must be completed before this policy is published.

Privacy requests

You can request access to, correction of or deletion of personal information you provided. Requests may require verification of account ownership, and applicable requirements or reasonable security needs may affect their handling. Use the privacy contact address below.
