Cookie Policy
Last updated: 4 October 2026
1. What cookies are
Cookies are small files a website stores on your device. Local storage works much the same way, inside your browser. This policy covers both, and we call them all "cookies" below.
2. Cookies SyncWave needs
These make the service you ask for work: being in a room, staying signed in, remembering your choices and applying an invitation you followed. They do not need your consent. SyncWave uses no other cookies of its own.
| Name | What it does | How long |
|---|---|---|
| sb-…-auth-token | Keeps your session, with or without an account, so you stay in your rooms and signed in. Local storage, and a cookie once you sign in. | Until you sign out |
| NEXT_LOCALE | Remembers the language you picked. | Session |
| sw_ref | The invitation code of the link you opened, so the friend who invited you and you get the invitation reward. Only our server can read it. | 90 days |
| sw_ref_seen | Lets the join screen say you were invited. It holds no code. | 90 days |
| syncwave-after-confirm | Where to take you back after you confirm your email. Local storage. | Until used |
| announcement:referrals, referrals:seen-qualified, banner:… | Remembers notices you have closed or already seen. Local storage. | Until you clear your browser |
Earlier versions of SyncWave also stored syncwave-cookie-consent and syncwave-analytics-consent, your answer to a cookie banner we no longer show. They are no longer read and you can delete them.
3. Visit statistics, without cookies
We use Vercel Web Analytics to count visits and pages, so we know what to improve. It sets no cookies and stores nothing on your device. Each visit is counted with a code computed from the request, which Vercel discards after 24 hours, and we only see totals: pages, where visits come from, country, browser and device type. Invitation codes are removed from the addresses before they are counted. The statistics cannot be linked to you; more in the Privacy Policy.
4. Third-party cookies
Some services we rely on set their own cookies, under their own policies:
- YouTube, when the player loads in a room. See Google's Privacy Policy.
- Google, only if you sign in with Google.
- Stripe, only when you pay, to process the payment and prevent fraud. See Stripe's Privacy Policy.
We cannot read or delete these cookies; your browser settings can.
5. How to control cookies
You can block or delete cookies in your browser settings. Blocking the necessary ones will stop SyncWave from working properly.
6. Changes to this policy
If we start using new cookies we will update this page and its date. If they need your consent, we will ask for it before using them.
