## Index

Tails: one task and one identity, erased at shutdown.
Qubes OS with Whonix: a continuing pseudonym isolated from personal activity.
GrapheneOS with Tor Browser: a dedicated Wi-Fi-only phone with no SIM, personal accounts, or commercial VPN.
OpenPGP with GnuPG: detached signatures for origin and integrity; public-key encryption for message confidentiality.
Monero: private digital payments with sender, recipient, and amount hidden by default.
VPNs: useful for geographic restrictions and reducing direct exposure, but not a basis for anonymity.
Messengers: encrypted content does not eliminate account, device, phone-number, provider, or legal-access risks; Signal and Matrix are presented as open-source alternatives.

## Limits

The page lists physical surveillance, hardware and local network records, Tor visibility, traffic correlation, account reuse, writing style, metadata, endpoint compromise, email metadata, private-key compromise, wallet compromise, VPN-provider trust, messenger metadata, exchange records, banking records, delivery details, and local legal restrictions.

OpenPGP signatures show that the holder of a specific private key signed the exact file. Identity still depends on checking the complete public-key fingerprint through an independent channel. OpenPGP encryption protects message contents but does not hide sender, recipient, subject, time, IP address, message size, or endpoint.

Monero is recommended as a payment tool, not an investment. Bitcoin exposes transaction amounts and address links. Monero uses ring signatures, stealth addresses, and RingCT, making XMR fungible. EU Regulation 2024/1624 applies to crypto-asset service providers from 10 July 2027.
