This policy explains how Sync BV uses cookies and similar technologies (such as browser local storage) on heysync.co. For how we handle personal data more broadly, see our Privacy Policy.
Cookies are small files stored on your device that let a website remember your actions and preferences. Similar technologies, such as local storage, work the same way.
We keep this simple. Our site currently sets only strictly-necessary and functional cookies and storage. We do not use advertising cookies, and we do not share your data with advertisers.
| Name | Type | Purpose | Duration |
|---|---|---|---|
| sync_lang | Functional | Remembers your language (English or French). Stored in local storage. | Until you clear it |
| __stripe_mid, __stripe_sid | Strictly necessary | Set by Stripe to process payments securely and prevent fraud at checkout. | Session / up to 1 year |
We do not currently use analytics or marketing cookies. If we introduce any in the future, we will update this policy and ask for your consent first, through a banner where declining is as easy as accepting.
Because we set only strictly-necessary and functional cookies, no consent banner is required today. You can still block or delete cookies and local storage in your browser settings; if you clear sync_lang, the site will simply default to its standard language until you choose again.
The only third-party cookies we currently rely on are Stripe’s, used to process payments. Stripe’s use of data is governed by its own privacy notice.
We may update this policy; the “last updated” date above reflects the current version.
