My Decks

• + New (sidebar) creates a deck — name, optional description, optional tags, and a Public/Private toggle. Public decks can be found by other users in Explore; private decks are only visible to you.
• Tag chips under "Your decks" filter the deck list down to decks carrying that tag. Click a chip again to clear the filter.
• Review all due reviews every card that's due for review, across all of your decks, in one session.
• Clicking a deck opens its panel: the Add card icon (a square with a plus) adds a card (front text, back text — both support basic Markdown — and an optional image). Card text is sized automatically to fill the card; the Text size slider under each preview makes that side's text bigger or smaller for just that card (100% = Auto). Edit deck / Delete deck change or remove the deck (deleting a deck deletes all its cards too). Review due reviews just this deck's due cards; Practice runs a random practice session (see "Reviewing & Practice" below).
• If a deck is public, a Reports button shows any mistakes other users have flagged on its cards (see "Reports" below).
• Each card in the grid shows when it's next due, a "Learning"/"Relearning" badge while it's still in its short steps, a mistake badge once it's racked up a mistake score, and a "Leech" badge if it's lapsed too many times. On public decks, unapproved cards also show a "Pending approval" badge.

Reviewing & Practice

• New and lapsed cards start (or restart) in short learning steps (minutes, not days) — Again or Hard repeats the current step, Good moves to the next one, and Easy skips straight to a full review interval. A card only enters day-based scheduling once it graduates out of its steps.
• Once a card is on day-based intervals, each grade recomputes its interval from its personal ease factor (starts at 250%): Again is a lapse — it drops the ease, sends the card back through a short relearning step, and the interval it lands on afterward is a small fraction of what it had; Hard grows the interval a little and nudges ease down; Good grows it by the ease factor; Easy grows it by the ease factor plus a bonus and nudges ease up. Intervals are jittered a few percent so cards graded together don't all come due on the same day, and a card that lapses repeatedly (8+ times) gets a "Leech" badge as a hint it might be worth rewriting or splitting.
• Every grade also nudges a separate, decaying "mistake score" that never affects scheduling: Again/Hard raise it, Good lowers it a little, Easy lowers it more — it never drops below 0.
• Practice sessions pick a set number of cards at random from a deck (cards can repeat), weighted so cards with a higher mistake score come up more often. Grading a card during Practice only updates its mistake score (Again/Hard raise it, Good/Easy lower it, by amounts you can set under "Study mistake weights" in your profile) — it never changes the card's due date, interval, ease, lapses, or learning state.

Explore

• Browse public decks made by other users. Opening one shows its cards — click to flip, or select cards with the checkbox.
• With cards selected, Create deck from selection copies just those cards into a new private deck of yours, or adds them to one you already have.
• Add whole deck to My Decks copies every card in that deck into a new private deck for you in one step.
• Each card has a report mistake button — it sends a message straight to the deck's owner about a problem with that card.
• Cards in public decks need to be approved before anyone but the deck's owner and admins can see them — unapproved cards show a small "Pending approval" badge (only admins actually see this, since unapproved cards from other people's decks are otherwise hidden). A deck with no approved cards yet won't show up in Explore at all.

Reports

• My reports lists mistakes you've reported on other people's cards, and their current status.
• Reports on my decks lists mistakes other people have reported on your public decks' cards. You can Resolve or Dismiss a report, optionally leaving a short response for the reporter.
• Status colors: Open (needs a look), Resolved, Dismissed.

Moderation (admins only)

• Lists every not-yet-approved card from any public deck, with a flip preview, the deck and owner, and any existing mistake reports (and the owner's responses) on that card.
• View card opens the full flip-card popup. Report mistake messages the deck owner about a problem, same as in Explore. Approve makes the card visible to everyone in Explore; Delete removes it entirely.
• Cards created in a public deck by an admin are approved automatically; everyone else's need this review step first.

Statistics (admins only)

• Study usage by time charts how many answers were revealed (cards flipped to the back) per hour, day, week or month over the chosen dates.
• Study usage by user ranks every user who studied in the chosen dates by their number of flips, most first.
• Both can be narrowed to admins or non-admins, and to Study or Anki mode. Hover a bar for exact numbers, or switch to the table view.

Import / Export

Open from the small icon next to "+ New" in the sidebar (no deck chosen yet) or next to the "Add card" icon on an open deck (that deck preselected).

• Export a deck downloads a .zip containing a JSON file (deck info and every card's fields) plus an "images" folder. A toggle controls whether studying status (due date, interval, ease factor, lapses, learning state, mistake score) is included or left blank.
• Import a deck reads a folder or a .zip in the same format, checks it thoroughly (deck name present, every card valid, every referenced image file actually there) before creating anything, then creates a new private deck. You can rename the deck on the way in, and choose to ignore the file's studying status and start every card fresh instead.
• Batch upload images turns a batch of image files into cards in one go — each image becomes a card with the image on the front and the filename (cleaned up) as the back text. Choose an existing deck, or create a new one on the spot.

Account & toolbar

• The theme switch toggles light/dark mode. Your email/name in the header opens your profile, where you can change your display name, password, or Study mistake weights.
• Log out ends your session. ? reopens this help, and About gives a short overview of the app.
