Deck Management

Active and Inactive Decks

Every deck has an Active or Inactive flag. This controls whether the deck's cards appear in your global study queue.

Active (default): Cards are included in the study queue. Due cards surface normally during Study sessions.

Inactive: Cards are silently excluded from the study queue without touching any card data. The deck is dimmed in your deck list and shows — for due and new card counts.

This behavior can be managed in your Settings section (found under your profile dropdown in the upper right of the Decks page).

When to use Inactive

  • You imported a deck to browse it but are not ready to study it yet
  • A course has ended and you want to park the deck without deleting it
  • You are taking a break from a topic but want to keep the scheduling state intact

Toggling a deck back to Active immediately restores all cards to the queue with their full FSRS state — intervals, stability, and due dates are preserved exactly.

How to toggle

  • Single deck: Open the ⋯ menu next to a deck, choose Deck Details, then under Study Status click Deactivate or Set Active.
  • Top-level deck: The ⋯ menu also includes Deactivate All, which deactivates the deck and all of its sub-decks at once.
  • Multiple decks: Use the MultiSelect button to select several decks, then choose Set Active or Deactivate from the bulk action bar.

Suspending and Burying Cards

Individual cards can be suspended or buried. Both states exclude the card from all study queues while keeping it in the deck.

You can suspend or bury a card during a Study or Review session using the Suspend and Bury buttons.

  • Suspended — the card is paused indefinitely until you manually resume it.
  • Buried — similar to suspended, but typically used for a temporary hold. A buried card stays buried until you manually unbury it.

To change a card's status, open the deck's ⋯ and go to Deck Details > Inspect Cards, then go to the Scheduling tab. Each card has a Status dropdown — set it to Suspended, Buried, or Active. To edit a card's content, see Editing Cards.

Suspended and buried cards are counted separately in deck stats and can be returned to Active at any time from the Inspect Cards page.

Suspending is useful when a specific card is not worth reviewing right now — a topic you already know perfectly, a card with bad content you plan to fix later, or a card that is temporarily out of scope. Use Bury when you want to skip a card for now but intend to return to it soon.

Sub-Decks

Flipnem supports Anki-style hierarchical decks using :: as a separator. For example:

Japanese
Japanese::Vocabulary
Japanese::Grammar
Japanese::Kanji

Sub-decks appear nested under their parent in the deck list. You can study a parent deck and its cards, or open a specific sub-deck to study just that branch.

When you import an .apkg that contains sub-decks, the hierarchy is preserved automatically.

Deleting a Deck

To delete a deck, open its ⋯ menu and choose Delete. The deck moves to the Deleted Decks page rather than being removed immediately (soft delete), so you have time to recover it if you change your mind.

Deleting a parent deck also moves all of its sub-decks to Deleted Decks together.

Deleted Decks

The Deleted Decks page is accessible from the Profile Menu under your email address. From there you can:

  • Restore — returns the deck (and all its cards and scheduling state) exactly as it was.
  • Delete permanently — frees up the storage immediately. This cannot be undone.

Decks that are not permanently deleted or restored will be purged automatically after 30 days.

Favorites

You can mark any deck as a favorite using the star icon. Favorites appear at the top of your deck list for quick access. The star is a visual convenience — it does not affect scheduling or export.
