Should I finish N5 first?

Yes; N4 assumes the 60 high-frequency N5 characters.

Do I need all readings?

Learn readings in common words first; add the rest through vocabulary.

Where is progress stored?

Only in local localStorage, never uploaded; full backup/restore is available.

Can I customize levels?

Yes; change cards per level (5-20) and daily limits in the plan.
