"Who got which duty in last quarter's rotation? I need to factor it into the next one." "What were the results from last year's event?" Lottery results aren't only consumed right after the draw -- you often want to look them up again later. If they disappear after a short window, that's not an option.
In Amida-san, events are accessible via URL for a set retention period. The free plan gives you 180 days, and the Organizer Plan (Pro) extends that to 365 days. This article explains how to use long-term storage to manage recurring operations.

A lottery isn't always one-and-done. Situations that demand a usable record are everywhere.
If retention is short, the URL eventually returns an expired state. You can no longer explain past decisions or verify them, and "was that draw really fair?" becomes an unanswerable question.
Amida-san's event results stay accessible via URL for a plan-dependent availability window.
| Plan | Availability |
|---|---|
| Free plan | 180 days |
| Organizer Plan (Pro) | 365 days |
Subscribing to the Organizer Plan (Pro) extends event availability to 365 days. A full year of access supports recurring duties and annual events well.

Within the availability window you can view results and download them as CSV / Excel on demand. Records stay pullable for the full duration.
If you used re-draw, the history of those redos is also visible for the duration of the availability window. "When did it change, and how" is auditable after the fact.
For shift or duty assignments you repeat regularly, long-term storage lets you check past results for bias.
For events that happen once a year or span fiscal years, 365 days of availability means you can prepare the next one with last year's record on hand.
For situations that require fair role assignment, keeping past results around lets you verify rotation fairness after the fact.
180 days. The Organizer Plan (Pro) extends it to 365 days.
Past the availability window, the event's results can no longer be viewed. If you need to keep them longer, Pro's 365-day window is the way to go.
Yes. While the event is within its availability window, the URL is browsable and downloadable as many times as you need.
Combine long-term storage with CSV / Excel downloads and you have records that don't depend on the availability window at all.
The Organizer Plan (Pro) is $39 / month or $390 / year (annual saves about 2 months). Extended availability is bundled with re-draws, participation restrictions, unlimited result downloads, and more.
