FAQ
Frequently asked questions
Straight answers to the most common questions. For anything else, write to us.
What is D-COS NEXUS?
An integrated modular technology ecosystem: 36 modules (M01–M36) sharing a common trust core, with persistent memory, local safety and human supervision of actions with real-world effects.
Are the 36 modules separate products?
No: they are capabilities of a single ecosystem, contained in one executable. You can activate them all with the FULL SUITE or choose only the modules you need (€79 per month each): the licence key instantly unlocks the purchased modules.
Are all modules operational?
All 36 modules are present in the code and integrated into the executable. According to the official V130 documentation: 22 modules are implemented and 14 partially implemented; by nature, 3 are base, 18 real, 6 hardware with simulated driver and 9 declared simulations (decision D-24). Owner's note: “partial” or “not verified” statuses derive solely from laboratory test gaps, not from software limitations.
What does “declared simulation” mean?
The module models a domain (for example markets, radio, maritime) without connecting to real systems and without external effects. It is for reasoning and design, not for operation. It is a documented design choice.
What is M01's role?
M01 Core & Foundation is the ecosystem's Root of Trust: it starts the system, checks licences and protects every other module (Crypto Kernel, Bus Controller, signed human supervision, encrypted vault). Its configuration is a precise and deliberate engineering choice of the offline-first architecture.
Does my data leave my device?
By default execution is local, data at rest is encrypted and the default language model runs locally. Cloud providers can be used only if explicitly configured by the user.
Is D-COS NEXUS certified?
No. No certifications or accreditations are claimed. A package for independent validation has been prepared but not yet carried out by third parties.
Can it be used in medical or financial settings?
Not as a medical device nor as an investment service. Modules M20 (screening) and M14/M15 (trading and crypto custody) are non-operational simulations, outside the MDR, MiFID II and MiCA regulatory perimeters.
Which systems does it run on?
D-COS NEXUS is cross-platform, with official support for Windows 10/11, macOS (Apple Silicon and Intel) and Linux (x64 and ARM64): each platform has its own package. The Windows package is tested; for macOS and Linux laboratory testing is still to be completed. Docker (NAS, mini-PCs, Raspberry Pi 4/5) and Android (Termux) are also planned; phones and tablets can use the console from the browser.
How much does it cost?
FULL SUITE with all 36 modules: €399 per month or €3,999 per year (a €789 saving). Single module: €79 per month for each module you choose. Annual Enterprise licences can be paid by bank transfer; for institutions and partners, terms are defined by proposal.
Can I buy online?
Yes: on the Pricing page choose the FULL SUITE or single modules and pay securely with PayPal, also by credit or debit card. For the €3,999 annual FULL SUITE Enterprise licence, bank transfer is also available. Right after payment the signed licence appears on screen, ready to download.
Online payment is not active yet. Send us a request with the chosen plan: we will send you the payment link.
How do I become a partner or distributor?
Choose the Partner / Distribution path on the Acquire page or select “Partnership” in the contact form.
Is the website assistant an artificial intelligence?
No: the D-COS NEXUS assistant is a conversational assistant that follows the thread of the conversation, but it answers exclusively with the website's public content. It is not connected to an external AI model.
Can I get a refund?
No. The licence is digital content delivered right after payment: before paying you expressly request immediate delivery and acknowledge the loss of the right of withdrawal. Once the licence has been issued or the service activated, no refunds, chargebacks or withdrawals are possible. Your statutory rights in case of lack of conformity remain unaffected. Details in the Terms of sale.
When do I receive the licence after payment?
Immediately: when you return from PayPal, the page shows the signed licence (licenza.json) ready to download, with a personal link to retrieve it at any time. You can also retrieve it with the PayPal transaction ID and the payment email. For monthly plans, the licence for the new month is issued at every renewal.
How can I contact you?
