If you unlock free membership or request the guide, we store your email to send it and occasional related updates. We never sell your data, and you can unsubscribe anytime.
Access, correct or delete your data at any time by emailing info@b-systems.ee.
We use only functional storage needed to run the tracker. No advertising or cross-site tracking.
