Cookie & Storage Policy
Last updated: 25 June 2026
1. Do we use cookies?
The public Synthin website does not use tracking or analytics cookies. No consent banner is shown because none is legally required. The sections below document everything that is stored on or read from your device.
2. Browser storage we use
| Name | Type | What it stores | Duration | Purpose |
|---|---|---|---|---|
synthin-lang | localStorage | "en" or "hu" | Until cleared | Remembers your language preference so you don't have to re-select it on every visit. Strictly necessary for the localised service. |
| Session cookie (portal) | HTTP cookie | Encrypted session token | Session / logout | Keeps you logged in to the client portal. Only set after you sign in. Strictly necessary — the portal cannot function without it. |
| Admin session cookie | HTTP cookie | Encrypted session token | Session / logout | Keeps the administrator logged in to the admin panel. Only set on the /admin route. Strictly necessary. |
3. Analytics — no cookies involved
We use Vercel Web Analytics to count page views. It does not set cookies or read anything from your device. Visitor identification uses a server-side hash derived from the incoming request (IP address + User-Agent), which is reset every 24 hours and cannot identify you across days or sites. Only aggregated, anonymised statistics are stored — we cannot identify individual visitors from them.
We also run our own page-view counter (ViewPing) which stores no IP addresses, user agents, cookies, or identifiers of any kind.
Because neither tool stores or reads anything on your device, the EU ePrivacy Directive’s consent requirement does not apply to them.
4. Third-party scripts
We load fonts via Next.js (next/font/google), which downloads and self-hosts them at build time. No requests are made to Google’s servers when you visit the site. We do not load any advertising, retargeting, or social-media tracking scripts.
5. Your choices
- Language preference:clear it any time via your browser’s developer tools (Application → Local Storage → synthinai.com →
synthin-lang). The site will fall back to your browser’s language setting. - Session cookies: sign out to delete them, or clear cookies for synthinai.com in your browser settings.
- Analytics: because Vercel Analytics is server-side and cookieless, standard browser opt-outs and ad-blockers do not apply. If you do not wish to be counted, you can use a privacy-focused browser that suppresses your User-Agent header.
6. Changes
If we add any new storage or tracking we will update this page and the date above before doing so.
