Local Web Crypto random selection. The calculation or transformation is deterministic for the same supported input, and the worked example below shows the intended scope.

Example

Coin Flip worked example

Input: one requested flip.

Expected output: the browser produces either heads or tails from secure random values.

Limits

Assumptions and limits

  • Inputs and files stay in this browser and are excluded from analytics.
  • The worked example assumes one requested flip.
  • Units, dates, rates, selections and source-file quality are taken exactly as entered unless the workspace labels a default.
  • Coin Flip implements the stated bounded method, not every possible interpretation of the task.
  • Check important output against the original data or an independent method before relying on it.

Privacy

Local processing

Values and files are processed locally in this browser unless the workspace explicitly identifies an optional network feature. Great Future does not intentionally collect tool inputs.
