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: + Card adds a card (front text, back text — both support basic Markdown — and an optional image). 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, and a mistake badge once it's been marked Hard more than it's been marked Good/Easy. On public decks, unapproved cards also show a "Pending approval" badge.

Reviewing & Practice

• During a review, flip the card to see the answer, then grade it: Hard resets its interval to 1 day; Good doubles the previous interval (minimum 2 days); Easy quadruples it (minimum 4 days). That interval decides when the card becomes due again.
• Every grade also nudges a hidden "mistake score": Hard raises 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. Practice never changes a card's due date or mistake score — it's just extra repetition.

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.

Import / Export

Open from the small icon next to "+ New" in the sidebar (no deck chosen yet) or next to "+ Card" 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, 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 or password.
• Log out ends your session. ? reopens this help, and About gives a short overview of the app.
