Privacy
Samurai Sums is designed to be playable without an account. We do not collect names, email addresses, school details or payment information.
Game preferences, recent games and local best scores are stored only in this browser using localStorage. This lets the games remember useful settings without sending that information to us.
The site keeps one anonymous aggregate counter of completed games, plus per-game totals. Starting, abandoning or exiting a game is not counted. Completion retries reuse a random duplicate-prevention key whose opaque hash expires within 24 hours. We do not attach names, accounts, schools, IP addresses, device details or gameplay histories to these totals.
Samurai Sums does not use Google Analytics or another third-party analytics service. Library searches, page visits, game results and outbound-link clicks are not sent to an analytics provider.
Outbound links to Numeracy Ninjas open the main Numeracy Ninjas website, which has its own policies.
Clear local game data
This removes Samurai Sums preferences, recent games and local best scores from this browser only.
