ABOUT MASTR. AND MASTRpass.
MASTR creates security information, onchain research, learning content and practical tools for crypto users.
MASTRpass is the offline vault app from MASTR. It does not need a MASTR account and does not connect to the $MASTR App services.
The $MASTR App uses accounts, wallet connections and messaging. MASTRpass stores its encrypted vault locally on the device.
KNOW THE LIMITS.
MASTRpass reduces specific risks. It does not remove your responsibility for backups, device security and careful verification.
Pre-release software
Security Beta/Alpha without an independent audit. Bugs, data loss and platform issues remain possible despite local testing.
Not your only backup
Keep multiple verified encrypted backups and store the recovery key separately and safely.
No financial advice
MASTRpass and linked MASTR content are not investment, legal or tax advice and do not guarantee protection from scams or loss.
Limits of local inspection
Offline tools inspect structure and cryptography, not current blockchain state, revocation lists, malware databases or reputation.
Your responsibility
Verify the domain, filename, SHA-256 and signature where available. Do not open a mismatched or unofficial file.
