When this is turned on, MnemoDeck shows a confirmation dialog every time you close the app. This prevents accidental closes — you must click Yes to confirm you want to quit.

When turned off, the app closes immediately without asking.

How to change: Toggle the switch to the right of “Confirm on quit”.

When turned on, MnemoDeck automatically selects the last deck you were using when you open the app next time. This saves you from having to navigate to it manually.

When turned off, no deck is pre-selected on startup.

How to change: Toggle the switch to the right of “Remember last selected deck”.

Choose between three visual themes:

• System — Matches your Windows theme. If your Windows is set to dark mode, MnemoDeck uses dark mode automatically.
• Light — Always uses a light background with dark text, regardless of your Windows setting.
• Dark — Always uses a dark background with light text.

How to change: Select the desired theme from the dropdown.

Sets the default font size for rich text fields (Description, Example, Note) when you create new content. This applies to new text you type into the rich text editors. Existing content that already has explicit formatting is not affected.

Range: 8 to 72 points.

How to change: Use the number box to type a size or click the up/down arrows.

Controls the size of the card’s Key (title) heading when you view cards in the Display View. A larger value makes the heading more prominent.

Range: 12 to 72 points.

How to change: Use the number box to set the size.

Controls the size of the question prompt text shown during quizzes. If you find quiz questions hard to read, increase this value.

Range: 12 to 72 points.

How to change: Use the number box to set the size.

Controls the size of the answer option text in multiple-choice quizzes. Useful if your card content is long and you need it to fit on screen without excessive scrolling.

Range: 8 to 36 points.

How to change: Use the number box to set the size.

When turned on, MnemoDeck periodically checks when you last made a backup. If it has been too long (see Reminder threshold below), a reminder popup appears near the gear icon in the title bar.

When turned off, no reminders are shown. You are responsible for remembering to back up on your own.

How to change: Toggle the switch.

The number of days since your last backup before MnemoDeck starts reminding you. For example, if set to 7, the app will remind you if you have not backed up in the last 7 days.

Range: 1 to 90 days.

How to change: Use the number box to set the number of days.

After you dismiss a backup reminder (by clicking “Got it”), this setting controls how many days pass before the reminder appears again (assuming you still have not backed up).

Range: 1 to 30 days.

How to change: Use the number box to set the frequency.

Displays the current size of the database file on disk. This is shown as a read-only label above the maintenance buttons so you can see the impact of compaction at a glance.

Runs a thorough verification of every table, index, and search index in your database. This checks that all data is consistent and no corruption has occurred. The check is read-only — it never modifies your data.

What you see: An indeterminate progress ring while the check runs (typically under one second). On success, a green “Database is healthy” message with the time taken. On failure, a warning with specific error details and a recommendation to restore from a recent backup.

When to use: After a suspicious crash or power loss, before creating an important backup, or any time you want peace of mind that your data is intact.

Rebuilds and compresses the database file, reclaiming space from deleted decks and cards. Over time, deleting content leaves unused space in the file. Compacting removes that overhead and can significantly reduce the file size.

What you see: The current database size is shown above the button. During compaction, a progress ring is displayed and database access is temporarily paused. Afterward, the before and after sizes are shown (e.g., “2.4 MB → 1.1 MB”).

When to use: After deleting a large deck or many cards, or if you notice the database file is much larger than expected. You do not need to run this regularly — MnemoDeck enables automatic incremental compaction after the first manual compact.

Note about first run: The first time you compact, MnemoDeck enables automatic incremental compaction. From that point on, small amounts of unused space are reclaimed automatically each time you close the app. A “✓ Auto-compaction enabled” indicator appears once this is active.

When you insert an image into a card using the rich text editor, it is resized to this percentage of its original dimensions by default. The resize dialog still appears, letting you change it each time.
