Your deck stays in this tab.
The package is read inside this browser tab. You don’t need an account, and your deck isn’t uploaded anywhere.
Questions
Is my deck uploaded anywhere?
No. Parsing happens in your browser; the page makes no network requests with your data.
Which files work?
.apkg deck exports and .colpkg collection exports, including the latest Anki format (zstd-compressed) and legacy formats.
Why don't I see retention or forecast?
Your export has no review history. In Anki, export with "Include scheduling information" checked (shared decks usually have it stripped).
Can I convert my deck to CSV?
Yes, free: all notes or just problem cards.
