Privacy Policy
Last updated: August 25, 2026
Your privacy is critically important to us. It is OddsCalculator.xyz's policy to respect your privacy regarding any information we may collect while operating our website.
1. Client-Side Calculations (Zero Data Collection)
We do not see, collect, or store the data you enter into our calculators.
All simulations (Poker, Blackjack, etc.) are performed locally in your web browser (Client-Side) using JavaScript and Web Workers. Your hand data, betting patterns, and strategies never leave your device and are not transmitted to our servers.
2. Information We Collect
Log Data
Like most website operators, we collect information that your browser sends whenever you visit our Service ("Log Data"). This may include your computer's Internet Protocol ("IP") address, browser type, browser version, the pages of our Service that you visit, the time and date of your visit, and other statistics. This data is anonymized and used solely for analytics to improve the Service.
Cookies & Consent
We use a small number of cookies for basic site functionality. Analytics (Google Tag Manager / Google Analytics) loads only after you click "Accept" in our cookie banner. If you click "Decline", no analytics scripts are loaded during that visit, and your choice is stored locally in your browser until you clear it. You can change non-essential cookie behavior at any time via your browser settings or by clearing this site's local storage.
Storage Inventory
For full transparency, this is the complete list of data this site stores in your browser. All entries are strictly local and functional — none of them are transmitted to our servers:
| Key | Type | Purpose | Duration |
|---|---|---|---|
cookieConsent | localStorage | Remembers your cookie banner choice | Until you clear it |
theme | localStorage | Remembers light/dark theme preference | Until you clear it |
sidebarCollapsed | localStorage | Remembers sidebar layout state | Until you clear it |
bj_state | localStorage | Saves your Blackjack calculator table between visits (cards stay on your device) | Until you clear it |
evTiers | localStorage | Saves your Expected Value calculator payout tiers | Until you clear it |
If you click "Accept", Google Tag Manager / Google Analytics may additionally set its own
cookies (_ga, _ga_*) as described in
Google's partner sites policy.
If you click "Decline", no such cookies are set.
3. Third-Party Services & Advertising Partners
We may use third-party service providers to monitor and analyze the use of our Service, and to display advertising:
- Google Analytics: A web analytics service offering detailed statistics about website traffic and traffic sources. Loaded only with your consent.
- Advertising: We may display advertising on this site, which may include ad networks and direct partnerships. Advertising partners may use cookies or similar technologies subject to their own privacy policies.
Affiliate disclosure: Some outbound links to gambling operators may be affiliate links, meaning we may earn a commission if you sign up through them, at no additional cost to you. We link only to operators we believe to be fully licensed and authorized in the relevant geographic location. Affiliate relationships never influence our calculator results or educational content.
4. Data Controller
The data controller for OddsCalculator.xyz is the site's operator. Because this site runs almost entirely without personal data, the practical point of contact for any data matter is our email below.
5. Your Data Rights (GDPR)
In accordance with the General Data Protection Regulation (GDPR), you have the right to access, rectify, or erase any personal data we might hold (e.g., if you emailed us directly). Since we do not store calculator usage data, there is usually no personal data to export regarding your site activity.
