Privacy Policy

Summary

• No account, email, or social login is required.
• A nickname is required before Timed, Continuous, or Equation starts. That nickname is the public name on the leaderboards.
• The phone keeps an install id, the nickname, sound, haptics, auto-submit, personal bests, and the last leaderboard it loaded.
• A submitted score is stored on our server: install id, nickname, mode, UTC day, score, misses, duration, time added, band counts, and the problems and answers from that run. The server recomputes the score instead of trusting the phone.
• An Equation attempt stores the install id, nickname, UTC day, duration, wrong-answer count, whether the player finished or left, and that day’s three problems and answers. The phone receives a problem only after that day’s attempt has started.
• Daily boards keep the best submitted score per player, per mode, for that UTC day. All-time boards keep the best score per player per mode.
• We do not sell this information. We do not ask for your name, contacts, or location for the leaderboards. Nicknames are 3–16 letters or numbers. Don’t use your real name if you don’t want it on the board.
• On iPhone the app signs in to Game Center. On Android it can sign in to Google Play Games once that project id is set. Friends can see that you’re playing. Scores are not posted to either service. Declining sign-in does not block play.
• A finished game can show one full-screen ad from Google AdMob. The ad is rated G and requested as non-personalized. The ad request does not include the nickname or the score. The app does not ask for tracking permission. Leaving a game does not show an ad.
• AdMob can still receive an IP address, a device advertising identifier, ad interactions, and diagnostics, and it may use the device identifier for advertising. Non-personalized ads do not make that “data not collected.”
• Premium is a one-time in-app purchase sold by Apple or Google. The store handles the payment. We do not receive a card number, and we do not send the receipt to the score server. Premium turns ads off and unlocks every Extra Difficulty level. Restore is in Settings.
• Email to contact@stealthlaunch.com includes your address and the message, so we can reply.
• Visits to stealthlaunch.com may be recorded in ordinary host logs (IP address, browser, pages). We do not add a marketing pixel on these pages.
