Terms of service
Use BitReach as transparent practice
Free educational game
BitReach provides a free single-player browser quiz about binary finger counting. No account, subscription, purchase, or camera is required. By using the site, you agree to use it lawfully and avoid interfering with its availability, attempting to bypass security controls, impersonating the operator, or presenting the game as an accredited assessment.
No grade, certification, or guaranteed outcome
Scores and adaptive review counters are casual practice feedback. They are not a course grade, diagnostic result, professional certification, accessibility evaluation, or promise that a learner has mastered binary arithmetic. Teachers may use the game as a discussion prompt but remain responsible for instruction, context, supervision, and any formal assessment.
Accuracy and availability
The operator aims to display correct place values and stable controls, but the site is provided on an “as available” basis. Browsers, devices, storage settings, and hosting infrastructure can behave differently. The service may change or be temporarily unavailable. Verify important educational decisions with an instructor or an independent reference. Report a reproducible arithmetic or accessibility error so it can be reviewed.
Original content and permitted use
BitReach's name, visual identity, writing, generated questions, feedback language, implementation, and generated production illustration are original project materials. Underlying binary arithmetic facts remain free to use. You may link to and play the public site. Do not copy substantial project assets or source presentation in a way that suggests endorsement, ownership, or affiliation. Runtime libraries retain their respective licenses as identified in THIRD_PARTY_NOTICES.
Local data and external links
Local progress belongs to the browser profile where it was created and can disappear when storage is cleared. The operator cannot restore it. Optional analytics is governed by the Privacy Policy. External support links open third-party services with separate terms and privacy practices.
Liability and contact
To the maximum extent permitted by applicable law, the operator is not liable for indirect loss arising from reliance on a casual game, temporary unavailability, or deletion of local progress. Nothing here excludes rights that cannot legally be excluded. Questions about these terms or a rights concern can be sent through the Contact page. Continued use after a posted update means the revised terms apply from their effective date.
