Standard generation is unlimited on every plan. Advanced generation: 3 per day with Free, unlimited with Pro. Free advanced generation requires a verified account and internet access; the allowance resets at midnight UTC.
Advanced features share the daily allowance in note 1.
Snapshot sharing is included on every plan. Joining cloud scenarios requires a verified account and an invitation. Hosting and syncing your own cloud scenarios requires Pro.
It means generating a schedule with advanced features: more than 50 active people, people attending only some rounds, or group-size limits that change between rounds. You can use these features 3 times per day with a free account; a Pro subscription removes that daily limit. Multi-round grouping, repeat minimization, and keep-together or keep-apart rules do not by themselves use this allowance.
Generating a schedule with one or more advanced features uses one generation, regardless of how many rounds the schedule contains. Generating another schedule with advanced features uses another generation. A free, verified account gets 3 per day, resetting at midnight UTC; unused generations do not roll over. You need an internet connection to start. Standard grouping does not use this allowance.
No account is needed for standard grouping, saving in this browser, or exporting your work. A free account gives you daily access to advanced features. Pro adds unlimited generation with those features and cloud sync.
Yes. Cancel from Pro & billing in your account. Your subscription renews monthly until cancelled, and access continues through your paid period.
Pro has no participant cap or daily generation limit. Practical limits depend on your device and scenario complexity. Cloud-storage limits still apply. A difficult or infeasible scenario may not produce a solution.
View cloud sync limitsPro is an ongoing subscription, billed automatically each month. Cancel at any time, effective at the end of your paid period. Pro has no participant cap or daily generation limit. Practical limits depend on your device and scenario complexity. Cloud-storage limits still apply.
