Your records belong to this browser.
Finished rounds are saved as you go, so an unfinished session can resume from its last completed round. A round interrupted mid-play starts again. Completed sessions keep their seed, settings and individual feedback.
Use export to keep a JSON copy, then import it into another browser. Import checks the settings and results before merging records. Clearing site data, private-browsing restrictions or unavailable storage can prevent long-term saving; the game explains when it cannot save.
Compare the same kind of practice.
Keep normal and Friday separate, and compare matching difficulty, skills and set counts. These records are personal practice feedback, not a population percentile or official daily streak. Records from other websites do not appear here automatically.
