K3 — Privacy

Last updated: 4 October 2026

What we collect

A browser cookie (k3_sid) so K3 remembers your guest bot and progress. It is not used for advertising.
Your trader name (and later an email address, if you sign up with one).
Your bots: their names, strategy settings, paper trades and results.
Basic technical data: your IP address (to stop abuse such as mass guest bots) and when you were last active.
Game data: XP, quests, energy and streaks.

Exchange API keys, wallet private keys, seed phrases, card details or money — not on the free version.

To run your bots and the game (energy, quests, leaderboard).
To show public leaderboards (trader name, bot name, avatar and paper results only — never your email or IP).
To study which strategies work across all users and improve K3's own bots.

We don't sell your personal data. Aggregated, anonymous strategy statistics may be used by K3 and may become part of a paid feature later.

Guest data with no bot is deleted after 7 days of inactivity. You can delete your bots at any time from the site. To delete everything, contact K3.
