Cookie and Local Storage Policy

Effective: September 5, 2026

FutariShiru uses cookies, browser local storage, and similar technologies needed to run the game, maintain anonymous authentication, restore purchased reports, and provide secure checkout.

1. Essential technologies

local storage that restores in-progress game data and results on your device;
Firebase storage used to maintain anonymous authentication;
a signed cookie used to restore access to a purchased report; and
hosting technologies needed for security, routing, load balancing, and abuse prevention.

These technologies are necessary for requested functionality and are not used by us for behavioral advertising.

2. Stripe and Link

When you open checkout, Stripe and Link may use cookies or similar technologies for payment, authentication, fraud prevention, localization, and transaction management. Their use is governed by their applicable privacy and cookie notices.

3. Analytics and advertising

We do not currently place optional analytics cookies or behavioral advertising cookies. If we introduce them, we will update this Policy and request consent where required before they are used.

4. Duration and control

Local game data remains until replaced or cleared. A purchased-report recovery cookie expires with the associated access period. Provider security and authentication technologies may have their own durations. You can delete cookies and site data through your browser, but doing so may remove in-progress game data or access saved on that device. Keep your PDF and recovery code secure.
