Cookie policy
Zenvorika sets no tracking cookies; this page lists the session cookie that keeps you signed in, the two small items kept in your browser, and the third-party requests made for fonts and live market data.
Last updated: 30 September 2026
1. Introduction
This Cookie Policy explains what information the Zenvorika website at zenvorika.com (the "Website") stores in, or reads from, your browser, and how you can control it. It should be read together with our Privacy Policy.
In short: the Website sets no cookies for analytics, advertising or tracking, and we do not ask any third party to set cookies. It uses one strictly necessary session cookie to keep you signed in, and your browser's localStorage for two small functional items. Your browser also contacts Google Fonts and Binance's public market-data service directly, as explained in section 4.
2. Cookies and similar technologies
Cookies are small text files that a website places on your device and that your browser sends back to that website with each request. Similar technologies include localStorage, which lets a website save small pieces of data in your browser. Unlike cookies, localStorage items are not automatically sent to the website's server; they stay on your device unless the page's own code reads them. In this policy we use "cookies" as a general term covering both, because the same consent rules often apply to them.
3. What the Website stores
The table below lists every item the Website stores in your browser.
| Name | Type | Category | Purpose | Duration |
|---|---|---|---|---|
| ZVSESS | First-party cookie | Strictly necessary | Holds a random session identifier that keeps you signed in to your Zenvorika account as you move between pages. The matching session on our server also carries a security token that protects forms against cross-site request forgery. Set with the HttpOnly and SameSite=Lax attributes, and Secure on HTTPS connections, so page scripts cannot read it and other websites cannot use it. | Until you sign out or close your browser |
| zv-cookie-consent | localStorage | Strictly necessary | Remembers whether you chose "Accept" or "Reject non-essential" on the cookie banner, so the banner is not shown on every page and your choice is respected. | Until you clear your browser storage |
| zv-favs | localStorage | Functional | Stores the list of markets you mark as favourites on the markets page, so they stay highlighted when you return. | Until you remove favourites or clear your browser storage |
The ZVSESS cookie contains only a random identifier, not your email address or password. Because it is strictly necessary for signing in, it is set regardless of your cookie banner choice; without it you cannot stay signed in.
The two localStorage items are not transmitted to Zenvorika and are not shared with anyone. The favourites list is created only when you use the favourites feature; it contains market identifiers and nothing that identifies you.
The Website does not use sessionStorage. If you are signed in, your practice-account balances and orders are saved to your account on our server, not in your browser. If you use the trading terminal without signing in, practice activity is kept only in the page's memory and is reset when you reload the page.
4. Third-party requests: fonts and market data
Google Fonts
To display its typefaces, the Website loads font files from Google Fonts, which are delivered from Google's servers. When your browser requests these files, your IP address, together with standard request information such as your browser type and the referring page, is disclosed to Google as the font provider.
The Website does not instruct Google Fonts to set cookies, and we do not receive any information from Google about your request. Google's processing of this data is governed by Google's own privacy policy. If you prefer to avoid this request, you can use a browser extension or setting that blocks third-party fonts; the Website will then use your device's fallback fonts and will remain fully usable.
Live market data from Binance
Prices, charts, 24-hour statistics, the order book and recent trades on the Website are loaded by your browser directly from Binance's public market-data API, at data-api.binance.vision, api.binance.com and, over a WebSocket connection, data-stream.binance.vision. Zenvorika does not operate this service. When your browser connects to these hosts, your IP address and standard request information, such as your browser's user-agent string, are visible to the data provider, which handles them under its own privacy terms.
These requests do not set any cookies of ours. Our server also fetches public prices from Binance to fill orders in signed-in practice accounts; those requests carry no information about you. If you block the Binance hosts in your browser, the Website will still load, but live prices and charts will not appear.
5. Analytics and advertising
We do not use analytics tools, advertising cookies, tracking pixels, social media plugins or session recording on the Website. Your visit is not measured or profiled for marketing.
If we decide to introduce analytics or other non-essential categories in the future, we will update this policy and the cookie banner first, and such items would only be activated if you have given your consent by choosing "Accept". If you have chosen "Reject non-essential", they would not be set.
6. Your choices
When you first visit the Website, a banner offers two options:
- Accept — allows non-essential categories if and when we introduce them.
- Reject non-essential — limits the Website to strictly necessary and functional storage.
Because no non-essential items are used today, both choices currently produce the same result on your device, apart from how your preference is recorded. Your choice is saved in zv-cookie-consent so we can respect it in future.
To change your choice, clear the Website's stored data in your browser; the banner will then appear again on your next visit. You can also:
- remove individual cookies, localStorage items or all site data through your browser's privacy or site settings;
- use private or incognito browsing, in which stored items are usually deleted when the window is closed; and
- block third-party requests, such as font downloads or market-data connections, using browser settings or extensions.
Deleting the ZVSESS cookie will sign you out. Clearing localStorage will remove your saved favourites and reset your banner choice. Neither affects the data saved in your account.
7. Changes to this policy
We will update this policy whenever we change what the Website stores, including before introducing any new category of cookie. The "Last updated" date at the top of the page shows when it was last revised.
