PRIVACY & LOCAL SAVES.

Last updated October 19, 2026

What the game stores

This game does not ask you to create an account, enter an email address, or provide a name. It uses your browser's local storage to remember the current daily and practice drives, replay action logs and comparisons, coach and sound preferences, up to 200 completed results, and first/best daily results for up to 90 challenge dates. Real game endings also keep their current daily and practice sessions and up to 90 first daily attempts in a separate local save. Continuation analysis runs in a browser worker, without uploading your actions. Guided lessons and shared historical/training challenges use separate local saves. Each shared mode keeps one current challenge; starting a different link replaces only that mode’s shared save. Historical replays can also retain the original action branch for comparison. This data stays in that browser; the game does not upload it to a player database.

What happens when you share

The Share result button creates a text summary of your game score, decision review or training grade, challenge, and first-attempt or replay label. Your browser may offer its system share sheet. Challenge links include the original scene, rules version, scene-pack version, seed and origin date, so someone else can start the same practice situation. They do not include your action log or saved progress. The game does not send the result to another person unless you choose a destination and complete that action. If the share sheet is unavailable, the game tries to copy the result or displays selectable text.

Hosting and technical requests

The site runs on Cloudflare. The hosting service processes requests needed to deliver the game, including technical information such as IP addresses, requested URLs, and browser information. The source enables Cloudflare operational logging for reliability. Access and retention depend on the site operator's Cloudflare configuration. This version includes no advertising or third-party font requests.

Site analytics

We use Plausible analytics, served from tj.chaozi.work, to measure page visits, outbound link clicks, and file downloads for 2mindrillgame.org. Your browser sends analytics requests to that service. Local game saves and replay logs are not included in these events.

Deleting or losing progress

Open My progress, expand Manage local saves, and choose which groups to remove: regular real-game endings, regular original drills, the guided lesson, the shared historical challenge, or the shared original challenge. Review the selection and confirm. Only the selected groups are cleared; a game that is already open starts fresh for the cleared mode. Removing all site data in your browser settings clears all groups together. Private browsing, blocked storage, a different browser or device, and clearing browsing data may prevent saves or remove progress. There is no account-based backup or sync.

My progress derives statistics from the records still retained in this browser. Daily firsts, recent records and first/best summaries are counted without duplicating the same result. Historical practice that has already been overwritten cannot be reconstructed, and the totals are not lifetime statistics. Original-drill teaching grades are kept separate from real-game decision reviews.

About this simulation

Historical starting situations and recorded endings come from nflverse play-by-play data. Original drills are fictional. All continuations are simulated, and decision reviews and legacy scores describe the game model, not real NFL win probabilities. This is an independent project with no affiliation with or endorsement from the National Football League or its teams.
