An orderly personal archive for owned and watched instruments, entirely within your browser.
PRIVATE COLLECTOR’S CATALOG
Document your instruments, not just their prices
Keep a local record of instruments you own or watch. Entries remain in this browser unless you export them. No account, tracking upload or server synchronization.
Browser data can be lost if you clear site storage or change devices. Export a backup. Imported files are read locally. Do not store sensitive personal information in notes.
