Privacy Policy.

1. Who is responsible for your data

Open Mine is operated by Everminer, LLC, a Delaware (USA) company — “the Operator”, “we” — which is responsible for the personal data described here. The roles of the Operator, the Providers, and you are explained in our Terms & Conditions. Contact details are in section 9.

2. What we collect

• Account data — your name and email address, and optionally a phone number or display name. If you sign in with a third-party account, we receive the basic profile and verified email it returns.
• Marketplace and ledger data — the miners you buy, sell, or hold, your Balance, deposits, refunds, hosting charges, and the mining-pool payout details you enter.
• Technical data — IP address, browser and device information, and timestamps, collected automatically so the Platform works and stays secure.
• Support data — the content of messages you send us.

We never take custody of your Bitcoin, and we do not ask for full bank-account or card numbers — payments are handled by the payment companies described in section 4.

3. How we use it

We use personal data only to:

• create and operate your account and sign you in;
• arrange the purchase and hosting of your miners with the relevant Provider;
• run the ledger — process deposits, bill hosting, and handle refunds;
• send service messages (sign-in links, verification, billing and balance notices);
• keep the Platform secure, prevent fraud, and meet our legal obligations.

We process this data to perform our contract with you, to operate and secure the Platform, and to comply with law. We do not use it for advertising.

4. Who we share it with

We do not sell personal data. We share it only where it is needed to run the service:

• Providers — the Provider hosting a miner you own receives what it needs to host it and support you.
• Companies that run parts of the Platform for us — hosting infrastructure, email delivery, error and performance monitoring, and payment processing. This includes Cyberian Mine GmbH (Berlin, Germany), which receives EUR bank transfers as the Operator’s payment-collection agent. They may process data only on our instructions.
• Sign-in providers — only if you choose to sign in through one.
• Google Fonts — our pages load fonts from Google’s CDN, so your browser connects to Google directly and Google receives your IP address. That is a technical necessity of displaying the site, not tracking.
• Authorities — where the law requires us to disclose data.

Some of these companies are located outside your country, including in the United States and the European Union, so your data may be processed there.

5. Cookies

We use essential cookies — they keep you signed in and let core features work — and one first-party campaign cookie: when you arrive through a tagged link or from another site, we remember that source for up to 90 days so that, if you create an account, we know which campaign or site brought you. It holds no identity and is deleted at sign-up. We do not use advertising cookies or third-party tracking. You can clear or block cookies in your browser, but blocking the essential ones will stop you from staying signed in.

6. How long we keep it

We keep account, marketplace, and ledger data for as long as your account is open, and afterwards only as long as we need it to meet accounting, tax, and other legal obligations — then we delete or anonymise it. Technical logs are kept for a shorter period, for security.

7. Your rights

You can access the personal data we hold about you, correct it, export it, or ask us to delete it, and you can object to or restrict some processing. Much of this you can do in your account settings; for anything else, contact us. Depending on where you live you may also have the right to complain to your local data-protection authority. Note that we may need to keep some records even after you close your account, where the law requires it.

8. Children

Open Mine is not for anyone under 18. We do not knowingly collect data from children; if we learn that we have, we delete it.

9. Changes and contact

We may update this policy; material changes are posted on this page, and where a change is significant we notify account holders. For any privacy question, or to exercise your rights, contact us at max@openmine.io.
