Guest Data Stays on Your
Property's Machines.
Front desk agents, event coordinators, and revenue managers are using ChatGPT, Claude, and Copilot every day, pasting guest reservations, credit card numbers, loyalty profiles, and event contracts into prompts. Transmute sits on your hotel's workstations and stops guest data from ever reaching an external AI model. No cloud. No vendor access. Just a local proxy that redacts sensitive data before it leaves your property network.
Transmute for Hospitality is a local desktop application that stops guest PII, credit card data, loyalty program records, and event contracts from ever leaving your hotel's computers, before that data reaches ChatGPT, Claude, Copilot, or any AI model. It runs on your existing property workstations, requires no cloud infrastructure, and helps hotels meet PCI DSS, GDPR, and CCPA requirements without changing how staff use AI tools for guest communications, loyalty analysis, or event planning.
The Payment Card Industry Data Security Standard (PCI DSS) applies to any organization that stores, processes, or transmits cardholder data. When a front desk agent pastes a guest's credit card number into an AI prompt, that data leaves the hotel's cardholder data environment, potentially violating PCI DSS Requirement 3 (protect stored cardholder data) and Requirement 4 (encrypt transmission across open networks).
Hotels routinely process data from guests across dozens of countries and U.S. states, each with its own privacy and breach notification requirements. GDPR applies to any EU resident's data regardless of where the hotel is located. California's CCPA/CPRA gives guests the right to know what personal data is collected and shared. All 50 U.S. states have data breach notification laws. When guest data enters an AI provider's systems through employee prompts, it may trigger notification obligations the hotel never planned for.
Transmute runs locally on your hotel staff's machines, no cloud processing, no vendor data access. Guest PII, credit card numbers, loyalty profiles, and event contracts never reach external AI providers. The redaction mapping stays on your machine, inside your property's network boundary.
Guest data exposure through AI is a PCI DSS and GDPR compliance risk
When a front desk agent pastes a guest's reservation, credit card number, or passport details into an AI prompt, that data leaves your property's controlled cardholder data environment and arrives at an external provider's servers. Under PCI DSS, hotels must protect cardholder data wherever it is stored, processed, or transmitted. Under GDPR, international guest data requires cross-border transfer safeguards. Transmute eliminates this vector entirely: sensitive guest information never leaves your network, so it never creates a PCI DSS, GDPR, or CCPA compliance exposure.

How Transmute Protects Guest Data at Your Property
From front desk to AI provider, every piece of guest data that would leave your property network is caught, redacted, and only the clean prompt makes it to the internet.
Compliance Frameworks That Apply to Hospitality AI Use
Hotels operate under multiple overlapping data protection frameworks, from payment card security to international privacy laws. Here is how Transmute maps to the requirements that matter when your staff use AI tools with guest data.
Protect stored cardholder data (Req 3); encrypt transmission across open, public networks (Req 4); restrict access to cardholder data by business need-to-know (Req 7)
Redacts PANs, cardholder names, and payment data before prompts leave the hotel's cardholder data environment. The AI provider never sees payment card information, satisfying the transmission encryption and data protection requirements for this vector.
Lawful basis for processing; data minimization; purpose limitation; cross-border transfer safeguards; 72-hour breach notification
Prevents cross-border data transfers of EU guest PII by redacting personal data before it leaves the local machine. Since the data never reaches external AI servers, there is no GDPR-regulated transfer, no processing by a third party, and no breach notification trigger.
Right to know what personal information is collected and shared; right to delete; right to opt-out of sale/sharing; data minimization and purpose limitation under CPRA
Prevents unauthorized sharing of California guest data with AI providers. Because Transmute redacts PII before it leaves the hotel's systems, the data is never 'shared' or 'sold' to a third party under CCPA definitions, satisfying the opt-out and data minimization requirements for the AI use case.
Notify affected residents (and often state AGs) within specified timeframes when unencrypted personal information is acquired by an unauthorized party; triggers vary by state for what constitutes PII and what qualifies as a breach
Transmute prevents the data exposure from occurring in the first place, guest PII is redacted before it can reach an AI provider's systems. No data leaves the hotel's control, so there is no unauthorized acquisition, no breach, and no notification obligation for this vector.
