Privacy policy
BtcMix provides privacy-preserving services. To deliver these services, we may collect and temporarily store limited information when a user visits the website, uses the service, or contacts our help desk. We minimize data collection and retain data only as long as necessary to provide the requested service.
If needed to resolve a support request, a user may voluntarily provide a name, email address, or information related to the Bitcoin addresses they used. This information is optional and is collected only when voluntarily submitted via our help center.
How we use information (NO-LOGS policy)
BtcMix may process limited user data solely to operate and improve the service, prevent abuse, and respond to support inquiries. We do not create user profiles and we do not monetize personal data.
Transaction data retention: all transaction-related details are automatically deleted 24 hours after the mixing transaction is completed. At a user’s explicit request, this window may be extended only as necessary to resolve a specific issue, after which the data is deleted.
Non-personal information
BtcMix does not collect analytics or behavioral tracking data about visitors. We may, however, detect basic technical characteristics needed to render the site and enhance privacy-related UX (for example, detecting the Tor Browser to suggest our .onion mirror). Examples of technical characteristics include:
- browser and device type,
- operating system,
- generic connection information (e.g., ISP or mobile carrier).
Third-party services
To protect your privacy, we do not use third-party analytics (e.g., Google Analytics) or advertising trackers. For additional privacy, you may access the Tor mirror of BtcMix using the Tor Browser; the core functionality is preserved there.
Cookies
BtcMix uses a short-lived wh_session cookie to maintain essential session state. This cookie is automatically deleted when you close your browser.
How we protect data
We apply administrative, technical, and organizational measures to protect data during collection, storage, and processing, and to prevent unauthorized access, alteration, disclosure, or destruction.
All data exchanges occur over encrypted channels (TLS/SSL on the clearnet or the encrypted Tor network). Where applicable, we use cryptographic signatures for additional integrity protection.
Sharing
We do not sell, rent, or trade personal information. Please note that Bitcoin transactions are recorded on a public blockchain. We cannot remove transactions from the blockchain or prevent third-party blockchain observers from analyzing on-chain activity.
Changes to this policy
BtcMix may update this Privacy Policy from time to time. We encourage users to review this page periodically to stay informed. Your continued use of the site or services after changes are posted constitutes acceptance of the updated policy.
Your acceptance
By using BtcMix (including its Tor mirror) and related services, you agree to this Privacy Policy. If you do not agree, please do not use the website or services.
