Cookie Policy
Link-Win uses cookies and similar technologies, including local storage and session storage, to improve convenience, manage sessions, ensure security, and prevent fraudulent use.
1. Purposes of Use
- Maintaining LINE or Web member login, store administrator login, and session status
- Managing language, screen state, in-progress reservation display, and security checks
- Detecting unauthorized access, excessive registration or login attempts, and system failures
2. Third-Party Services
The Service uses Vercel, Supabase, LINE, Stripe, Cloudflare, Resend, Upstash, and other external services for hosting, authentication, data storage, payments, email and LINE notices, scheduled processing, and security checks. These external services may use cookies or similar technologies.
3. Disabling Cookies
Users may disable cookies in browser settings. Doing so may prevent login, point checks, reservations, store administration, payments, security checks, and other core functions from working properly.
The public homepage, practical guides, and product demo use sessionStorage for measurement. The random session ID, acquisition context, and internal-review display classification are kept only for one use in the same browser tab and are not used to identify visitors across sessions or devices. They are removed when the tab is closed or browser storage is cleared. After a new store is registered, its store ID, classification, and milestone records are managed by the service; the link to acquisition-source details is deleted after no more than 90 days.
