How this game handles your data. Last updated June 2026.
Playtest buildPortal to Pluto is a game that runs entirely in your browser. There are no accounts and no logins. We don't sell your data, we don't run ad or analytics trackers, and we don't set tracking cookies. The only information that ever leaves your device is what you choose to send us (feedback) and anonymous records — a game record at the end of a match against the computer, and a small anonymous summary of how you're getting on (for example, how far you reached in the tutorial). Neither identifies you.
When you send feedback (the Feedback button — entirely optional), the form sends us:
At the end of a game against the computer, the app sends an anonymous game record (the difficulty, the setup faced, who won, and the sequence of moves) so we can study how players beat the AI. It contains no name, email, or anything that identifies you.
As you play, the app also sends a small anonymous usage summary — things like how far you got in the tutorial, how many games you started and won, and rough timings — so we can see where new players get stuck and make the game easier to learn. It carries a random, non-identifying id so one device's visits group together, and no name, email, or anything that identifies you.
Stored on your device only (never sent anywhere): a randomly-generated callsign, your daily puzzle scores, your saved game so you can resume, and your display preferences. Clearing your browser storage removes all of it.
We don't share your information with anyone else.
Feedback is always optional — don't send it and we receive nothing from you. To ask what we hold about you, or to have it deleted, email brucereed99@gmail.com. This is an early playtest, so this policy may change as the game grows; the date above tracks updates.
