Cookie Policy
Last updated: 9 November 2026
1. What cookies are
Cookies are small text files a website stores on your device. Websites also use similar tools, such as local storage and session storage in your browser. In this policy, "cookies" covers all of them.
This policy explains which cookies synona.app uses, why, and how you can control them. Synona is a product of AI CTRL Ltd.
2. Kinds of cookies we use
Strictly necessary (always on)
These make the site work and keep it safe: they remember your cookie choice, protect the request form from spam and, when the dashboard opens, keep you signed in. The site cannot work properly without them, so they do not need your consent.
Analytics (only with your consent)
These help us understand how visitors use synona.app, so we can improve it. We use PostHog, hosted in the European Union. When you send the request form, we link your analytics events to the email address and website you entered. If you do not consent, these cookies are not set.
We do not use functional or preference cookies.

4. Managing your cookies
Cookie banner
On your first visit, a banner asks whether you accept analytics cookies. To change your choice later, use the "Cookie settings" link in the footer of any page.
Your browser
Most browsers let you block or delete cookies and site storage in their settings. If you block strictly necessary cookies, the request form or sign-in may not work.
5. No advertising or social media tracking
synona.app does not use advertising cookies or social media tracking pixels. We read advertising click identifiers from the address you arrive on only to know which campaign brought you; we do not send them back to advertising networks.
We do not sell your data to advertisers.
6. Changes to this policy
We may update this policy when the cookies we use change, or when the law changes. When we do:
- we update the "Last updated" date at the top of this page;
- if we add a new kind of cookie that needs consent, we ask you again through the banner.
For more on how we handle personal data, see our Privacy Policy.
