Cookie policy
Every cookie and browser storage key Sioma sets, what each one does, who sets it, and how to change your mind at any time.
Last updated 3 October 2026
Introduction
This Cookie Policy describes how Sioma uses cookies on our website at sioma.ai, control.sioma.ai and any other site we operate (collectively, the "Website"). Sioma is not yet an incorporated company: it is operated by Sagi Gleizer as an individual trading as Sioma, and "we", "our" and "us" mean that operator.
Using the Website is not agreement to cookies. We ask you, once, in a banner on your first visit, and nothing loads from our analytics vendor until you have said yes — not the cookie, not the script, and no session replay. The only cookies set before you answer are the strictly necessary ones: what keeps you signed in, and what remembers your answer itself. Our fonts and scripts are served from our own site, so loading a page tells no one else you are here.
This Cookie Policy is an integral part of our privacy policy, which covers everything else we hold about you and how to ask for it or have it deleted.
1. What are cookies?
Cookies are small data files downloaded and stored on your device while you browse a website, often used to keep a record of actions taken on that site or to track related browsing activity. Some are set by the site you are visiting; others are set by third parties whose services that site loads.
Cookies are not the only thing a site can store. We also use localStorage and sessionStorage, which are not cleared by clearing your cookies — so the table below names both, rather than letting "cookie" stand in for all of them.
For more about cookies and how to control them, see your browser's help pages or aboutcookies.org.
2. What we set
| Name | Kind | What it does | Set by | Kept for |
|---|---|---|---|---|
Consent choice (sioma_consent) |
Cookie, necessary | Remembers your answer to the banner, so we stop asking. Shared across sioma.ai and its subdomains. | Us | 180 days |
Session (sioma-control.*) |
Cookie, necessary | Keeps you signed in to the application at control.sioma.ai. Without it you cannot use an account. It is not set on this website. | Us | Until you sign out, or the session ends |
Analytics (ph_<project key>_posthog) |
Cookie and localStorage, analytics | Identifies your browser across visits so visits and games played can be counted. It carries no name or email address. Only after you accept. | PostHog | 1 year |
Analytics (ph_<project key>_window_id and similar) |
sessionStorage, analytics | Groups the pages you view in one tab into a single session. Only after you accept. | PostHog | Until the tab closes |
Analytics opt-out (__ph_opt_in_out_<project key>) |
localStorage, necessary | Only if you accept and then withdraw: holds PostHog's own "stop" for the rest of that page, and is removed on the next one. | PostHog | Until your next page |
3. Opting out and changing your mind
Analytics is off until you accept it, wherever you are in the world. Rejecting is exactly as easy as accepting, and the banner never blocks the page. Your choice is stored in this browser, applies from your next page view including on future visits, and can be changed at any time:
Withdrawing consent stops capture and clears the identifier PostHog had set for this browser.
You may also opt out through your browser. Most browsers let you control cookies — whether to accept them, how to remove them, and whether to warn you before one is set — and some, such as Google Chrome, let you block cookies from one specific site while leaving others alone. Browser extensions that block analytics work on this site too. Nothing here breaks if you use any of these: this website has no cookie it needs in order to function, though blocking all of them means you cannot stay signed in to the application.
Browser privacy signals. Some browsers send a "Do Not Track" header, and some send a Global Privacy Control (GPC) signal, which asks a website not to sell or share your personal information. On this Website there is nothing for either of them to switch off. No analytics vendor runs at all unless you have accepted the banner; we run no advertising pixels; and we do not sell or share your personal information for cross-context behavioural advertising. What those signals ask for is already what we do by default, for every visitor. The banner, not the signal, is the control — and you can change your answer at any time.
4. Details: who sets what
We use services provided by others to run the Website and the product. Some of those services collect data about you independently, for their own purposes, under their own privacy policies. The sub-processors whose services place cookies or similar storage in your browser are:
| Provider | Why | Where | Their policy |
|---|---|---|---|
| PostHog | Website analytics, with your consent | United States | posthog.com/privacy |
Providers that process your information but set nothing in your browser — hosting and transactional email among them — are listed in full in section 5 of the privacy policy.
5. General
Your answer is kept for sioma.ai and its subdomains, so you are asked once.
We may change this Cookie Policy from time to time. Please check the "Last updated" date at the top of this page to see when it was last revised. If you have any question about cookies or about anything else we hold, write to privacy@sioma.ai.
