Cookie Policy
Last updated: April 12, 2025
This Cookie Policy explains what cookies are, which ones Synchro uses, and why. Synchro is operated from Lithuania and complies with EU GDPR and the ePrivacy Directive.
What are cookies?
Cookies are small text files stored in your browser when you visit a website. They allow the site to remember information about your visit — for example, that you are logged in — so you do not have to re-enter it on every page.
Cookies we use
Synchro only uses strictly necessary cookies. These are required for the site to function and cannot be disabled without breaking core features. No tracking, advertising, or profiling cookies are used.
| Cookie name | Purpose | Duration | Type |
|---|---|---|---|
__session, __client_uat | Set by Clerk (our authentication provider) to keep you signed in and verify your session securely. | Session / up to 1 year | Necessary |
cookie_consent | Stores your response to this cookie banner so we do not show it again. | 1 year | Necessary |
twitter_oauth_* | Temporary cookie used only during the Twitter/X account connection flow to prevent CSRF attacks. Deleted immediately after the OAuth callback completes. | Session (minutes) | Necessary |
Third-party analytics
Synchro uses Vercel Analytics and Vercel Speed Insights to understand site traffic and performance. These services are cookieless — they do not set any cookies or store personal identifiers in your browser. Aggregate, anonymised data is collected in accordance with Vercel's privacy policy.
Managing cookies
Because all cookies we set are strictly necessary, declining cookies via our banner does not affect their placement — it only records your preference. You can delete or block cookies at any time through your browser settings. Note that blocking authentication cookies will prevent you from signing in.

Changes to this policy
We may update this Cookie Policy if we add new features that use cookies. The "Last updated" date at the top of this page will reflect any changes.
