Safety and Transparency

97 Lottery is an independent, education-first site. We do not sell tickets or accept wagers. The predictor is deterministic and intended for study and record-keeping. Outcomes are uncertain; short-term variance is expected.

“Deterministic” means the same inputs always produce the same outputs. It does not imply guaranteed results.

Data & Privacy

  • No ticketing or wagering data is collected by this page.
  • Limited operational analytics may be used to improve usability and stability.
  • PWA caching stores recent assets on your device for faster loads; you can clear site data at any time.

Compliance & Disclaimers

  • This site does not operate or promote gambling products.
  • No guarantees of profit or “sure-win” strategies are made or implied.
  • Content is intended for adults (18+). Use strict session limits and pause when tired.
