Cookie Policy
1. What cookies are
Cookies are small text files that a website stores on the user's device (computer, smartphone, tablet) during a visit. They let the site “remember” the user's actions and settings for a certain period of time.
2. Cookies we use
| Cookie | Purpose | Duration | Type |
|---|---|---|---|
studio_session | Session of an authenticated user. Stores the session token as httpOnly + Secure + SameSite=Lax. | 30 days | Strictly necessary |
studio_ref | Referral link attribution. Remembers the referral code so the reward can be credited to the person who sent the invitation. | 30 days | Functional |
pz_login | Sign-in protection: a one-time state code that confirms the response from Polyzon belongs to the sign-in attempt you started. | 10 minutes | Strictly necessary |
pz_sidebar, pz_panels, pz_chats | Studio interface settings: whether the sidebar is collapsed, the panel widths, and whether the assistant's chat list is shown. Contains no personal data. | 1 year | Functional |
2.1. In addition to cookies, the site uses the browser's local storage (localStorage and sessionStorage) for settings that never leave your device: a mark that you have read this notice, drafts of descriptions and OpenSCAD code, favorite tools, collapsed sections, hints shown once, and the paused animation on the home page. These entries are deleted together with site data in your browser settings. A signed-in user's favorite tools are also saved in their account.
2.2. The site has no analytics, advertising, or third-party cookies: it does not use visitor counters or ad networks. The YooKassa payment page opens on YooKassa's own domain and uses cookies under YooKassa's rules.
3. Legal basis
3.1. Strictly necessary cookies are required to sign in and to protect the account, and they are processed to perform the contract with the user (Article 6(1)(5) of Federal Law No. 152-FZ “On Personal Data”).
3.2. Functional cookies remember interface settings and the referral link the visitor came from. They contain no information that could identify the visitor. You can delete them in your browser settings, and the Service will keep working.
3.3. If analytics or advertising cookies are ever added to the site, they will be set only after the visitor gives separate consent, and this policy will be updated.
4. Managing cookies
4.1. The user can:
- disable all cookies in the browser settings;
- delete cookies that have already been set, using the browser settings;
- set up a notification when specific sites set cookies.
4.2. Disabling strictly necessary cookies will make the Service unusable: signing in to the account will not be possible.
4.3. Instructions for managing cookies in popular browsers: Chrome, Firefox, Safari, Edge.

The Operator reserves the right to update this policy. The current version is always available at https://studio.polyzon.org/en/legal/cookies.
