Frequently Asked Questions
FAQ
Conectum is a Web3 privacy portal offering secure services like VPN licenses, eSIMs, one-time numbers, and flashing of Castrum OS.
We support Castrum OS, a hardened and encrypted Android operating system without Google services, trackers, or analytics — fully privacy- and security-oriented.
You connect your crypto wallet (e.g., MetaMask). No email, no password, no personal data.
Instead of storing your wallet address like:
0x98aF3E43bBcC9a11eE49FfA0Dd0F5A0a34EbdC92
We store a persistent anonymous token, e.g.:
user_id: 13fa97e9a43cd85e13e26aeff3d1d9fcb4a2d9ce9b…
This lets you access your purchases later — without ever revealing your identity.
No.
We never store, process, or log your actual address — only a one-way anonymized hash used to show your own data.
Authentication is done by signing a message from your wallet.
This generates a persistent anonymous token (derived from your wallet) that links to your data — without revealing your identity or allowing any tracking.
No.
Not even we can. The system uses anonymous cryptographic identifiers that cannot be reversed into wallet addresses or real-world identities.
Yes.
You can use any Web3 wallet that supports message signing.
All credits are added exclusively through cryptocurrency. We do not accept cards, bank transfers, or anything requiring KYC — to protect user anonymity.
You can buy:
- VPN licenses (6 or 12 months)
- Global eSIM data packages
- One-time phone numbers
- Castrum OS flashing for Pixel devices
It’s a virtual phone number that can receive one SMS verification code — ideal for registering on apps like Signal, Telegram, and similar platforms.
We offer 6-month and 12-month VPN licenses. They’re activated manually on your device and are not linked to any account.
