Modern internet spaces are broken. Countless educational websites subsist by cluttering screens with intrusive advertisements or locking their best features away behind aggressive paywalls. We fundamentally refuse to follow this pattern. Our project is built on the belief that premium learning tools should never be restricted by financial status.
Imagine arriving at a restaurant, only to be told you must pay a premium cover charge just to open the menu and look at the list of available items. Does that feel right? Or imagine buying an educational textbook, only to find every other page blacked out with a lock icon demanding a monthly subscription. Education shouldn't be hidden in the shadows.
We believe that clarity, accessibility, and focus are the absolute prerequisites for mastering complex mental skills like rapid calculation. True learning platforms should exist to elevate their students, not exploit their attention spans.
We proudly draw inspiration from open systems like Lichess.org. On our platform, every user—regardless of background, location, or financial standing—will always have total, unrestricted access to every single feature we build. No tiers, no hidden premiums, and no systemic biases.
As our active student directory grows, running real-time global rankings, persistent leaderboard systems, secure user databases, and reliable computational servers will incur ongoing infrastructure costs. To handle this sustainably, we intend to implement an optional donation module in the future once the user base scales significantly.
However, let us make one promise absolute: Donors will receive the exact same application experience and feature access as everyone else. Financial contributions will strictly serve to support background server upkeep, ensuring the ecosystem stays alive and robust for the community. We are here to create value, and we intend to remain exactly like this forever.
