Source: https://quantumines.com/privacy Published: 2026-11-02 ยท Last updated: 2026-11-03 Publisher: Quantumines (https://quantumines.com/), founded by Muhammad Ali Raza (Ali Arbi) Quantumines collects only what it needs to run accounts, answer messages and understand how the site is used. We do not sell personal data, show ads, or use third-party trackers. This policy covers quantumines.com. Each Quantumines product (Hunt4Coin, ChessMess, CryptoMerchant, TwapTrade, ProxyFall, VerifDoc) has its own website and its own privacy policy. ## Who we are Quantumines is a technology and product studio based in Lahore, Pakistan, founded by Muhammad Ali Raza. Contact us about privacy at hello@quantumines.com. ## What we collect and why | Data | Why | Kept | | Account: name, email address, a one-way hash of your password, sign-up and last log-in dates, and how you found us when you signed up (for example "Google" or "ChatGPT", the referring page and the first page you visited), your country and city at sign-up, and your device type | To give you an account, keep it secure and let you reset your password | Until you ask us to delete your account | | Projects and messages you write in your account | To discuss and deliver your project | Until you ask us to delete them, unless we must keep them for an agreement or the law | | Contact form: name, email, company and message, plus your country and how you found us | To reply to you | Up to 2 years after our last exchange | | Emails you send to any @quantumines.com address | To read and answer them | Like any business inbox, until no longer needed | | Visit statistics: page visited, referring site, country and city (from our network provider), device type, browser, operating system, screen width, language, time on page, and whether your browser has visited before (with how many days ago and on how many days) | To see which pages help people and fix what doesn't | 25 months | ## How our visit statistics work We count visits with our own analytics, built into this site. It uses no cookies and no third-party service. To count unique visitors, the server combines your IP address and browser details with a secret that changes every day and keeps only the resulting code. Your IP address is never stored, and the code cannot be linked to you or to your visits on other days. If your browser sends a "Do Not Track" signal, no statistics are recorded at all. When you create an account or send the contact form, we look up how you arrived on the site during the previous 24 hours in these statistics (for example from Google, an AI assistant such as ChatGPT, or a link on another site) and save that with your account or message, so we know which channels bring people who want to work with us. We also log visits from search engines and AI crawlers (such as Googlebot or GPTBot) by their published name, so we can see how our pages are indexed. ## Cookies and browser storage - Session cookie (qm_session): set only when you log in, so you stay logged in for up to 30 days. It is required for the account to work. - Visit counter (quantumines-visits in your browser's local storage): the date of your last visit and how many days you have visited, so our statistics can tell new visitors from returning ones. It holds no ID, is never readable by other sites, and only the yes/no "visited before", the days since the last visit and the number of days are sent with each page view. It is not created if your browser sends Do Not Track. You can clear it by clearing this site's data. - Theme preference: if you switch between light and dark mode, your browser remembers the choice locally. It is never sent to us. ## Who processes data for us - Railway hosts the website and its database. - Cloudflare delivers and protects the website and tells our server which country a visit comes from. - Postmark sends account emails (confirmations, password resets, project updates) and receives email sent to @quantumines.com. They process data only to provide these services to us. ## Your choices and rights You can update your name and password in your account at any time. To get a copy of your data, correct it, or delete your account and everything linked to it, email hello@quantumines.com from the address on your account. We reply within 30 days. ## Security Passwords are stored only as salted one-way hashes. Connections to the site are encrypted, log-in attempts are rate-limited, and the master panel is restricted to one verified account. ## Changes If this policy changes, we update the date at the top of this page. Significant changes are also announced to account holders by email.
