Privacy

Collector Atlas has no accounts and collects no personal information. Your owned/missing marks are stored only in this browser, on this device. Nothing about your collection is uploaded or synced.

Because that storage lives in your browser, it can be lost if you clear site data. Exporting a backup file — and keeping it somewhere safe — is the way to protect it. Resetting your collection will always ask for explicit confirmation first.

No third-party analytics or tracking is enabled. If that ever changes, this page will say so plainly before it ships.
