This Cookie Policy explains how Eudaimonia Universe JAPAN uses cookies and similar technologies (local storage, SDKs, pixels) on omusubiquest.com and in the OMUSUBI QUEST app (the "Service"). It supplements our Privacy Policy.
1. What Are Cookies?
Cookies are small text files placed on your device when you visit a website. Similar technologies (such as local storage and mobile SDKs) perform comparable functions in apps. We use the term "cookies" to cover all of these.
2. Categories We Use
2.1 Strictly necessary (always active)
Required for the Service to function — authentication and session management, security (fraud prevention, CSRF protection), load balancing, remembering your cookie choices. These cannot be switched off. Legal basis: our legitimate interests / necessity to provide the service you request.
| Cookie/Technology | Provider | Purpose | Duration |
|---|---|---|---|
| sb-*-auth-token (Supabase Auth) | Eudaimonia Universe JAPAN | Login session | Up to 400 days, refreshed while you use the Service |
| __stripe_mid / __stripe_sid | Stripe | Payment fraud prevention | 1 year / 30 min |
2.2 Functional (consent where required)
Remember your preferences — language, theme, display settings.
| Cookie/Technology | Provider | Purpose | Duration |
|---|---|---|---|
| homo3_* (local storage) | Eudaimonia Universe JAPAN | Language and display preferences | Until deleted by you |
2.3 Analytics (consent where required)
We do not currently use third-party analytics cookies. If we introduce analytics in the future, we will update this Policy first, configure the tool to minimize data collected (e.g., IP truncation), ask for consent where required, and never apply analytics to the content of your journal entries.
2.4 Advertising
We do not use advertising or cross-site tracking cookies. If this ever changes, we will update this Policy and ask for your consent first.
3. Your Choices
- Consent banner: where required by law (e.g., EEA, UK), non-essential cookies are set only after you consent via our banner. You can change or withdraw your consent at any time via Cookie Settings in the footer or app settings.
- Browser controls: most browsers let you block or delete cookies. Blocking strictly necessary cookies may break the Service.
- Global Privacy Control: we honor GPC signals where legally required.
- Mobile settings: your device OS provides controls for app-level identifiers.
4. Third-Party Cookies
Some cookies are set by third parties (e.g., Stripe for payment security). We do not control these cookies; see the third party's own privacy and cookie policies for details.
5. Changes
We may update this Policy as our use of cookies changes. Material changes will be notified via the Service. The table above is reviewed at least annually.
