The legally required disclosures for ZER0ONE and the full privacy statement under GDPR and Serbian personal-data protection law.
Note
ZER0ONE OÜ (Estonia) is currently being incorporated via the Estonian e-Residency programme. Mandatory identifiers that are issued only upon entry into the Estonian Business Register (Äriregister) — Registry Code, VAT number and board member's name — are explicitly flagged as pending here and will be filled in immediately after registration. Until then, I, Michael Jajagin, act personally as an independent software engineer based in Bogojevo, Republic of Serbia.

Until registration completes, Michael Jajagin acts as a natural person (see service-provider section above), based in Bogojevo (Republic of Serbia), and bears personal responsibility. Estonian Registry Code, VAT number and board member will be added once registration completes.
