Review algorithm

Missed days

Nothing is lost. Word progress is not reset; your streak is the only thing that genuinely breaks. In fact, if you recall a word correctly after a break, Tomyo credits all the time that actually passed: since the word survived longer than planned, the next gap grows even wider.

Being overdue is information, not a penalty

When a word arrives late and you still recall it, that is proof it holds in memory longer than Tomyo assumed. Such an answer is worth more than a review done on time, and the gap to the next encounter grows based on the time that really passed rather than the time that was scheduled.

If the word would not come, it simply returns more often. That is the ordinary stage drop — the same one that happens after a mistake with no break involved.

What the first session after a pause looks like

After a break, accumulated reviews take priority. A long absence with a substantial backlog may trigger Welcome back: a short session with a small amount of new material. This temporary mode helps you return to regular study.

You do not need to clear it all at once, and it does not help. A few sessions in a row handle a queue better than one very long session you never want to repeat.

After a long break

The break itself does not lower word stages. If you forget a word during a review, your answer updates its state and it returns more often. Words you recall confidently keep their progress.

When Welcome back ends

The mode appears only when the break and workload qualify. It ends as the backlog shrinks or the return period expires. If you do not see the badge, your data has not disappeared; Tomyo may have chosen a regular session.
