Zero-compromise security: how Yellsy protects your data
Yellsy applies military-grade encryption at every layer: at rest, in transit, and across all provider API connections.
Data security at Yellsy is not a feature toggle — it is the foundational layer on which every other part of the platform is built. Every piece of sensitive data you share with us is protected using the most rigorous commercially available standards, from the moment it enters our system to the moment it leaves.
Data privacy framework
Yellsy LLC operates under a data minimization principle: we collect only the data strictly necessary to deliver your travel services. Our practices align with GDPR obligations for European users and CCPA requirements for California residents. No personal data is sold, rented, or shared with third parties beyond the booking partners required to fulfill your reservation.
Encryption at rest (AES-256-GCM)
All sensitive fields stored in Yellsy's databases are encrypted using AES-256-GCM before being written to disk. This includes your passport number, date of birth, payment token references, booking history, and any other personally identifiable information. Even if a database were somehow accessed without authorization, the encrypted fields would be computationally infeasible to read without the corresponding encryption keys, which are stored separately in a secure key management system.
Encryption in transit (TLS 1.3)
All data transmitted between your browser and Yellsy's servers, and between Yellsy's servers and our booking partners (Duffel, Amadeus, Hotelbeds), is encrypted using TLS 1.3 — the current strongest version of Transport Layer Security. This prevents any interception of data in motion, whether on public networks or direct server connections.
Anti-scraping and infrastructure protection
Yellsy's infrastructure is protected against automated scraping, credential stuffing, and denial-of-service attempts using rate limiting, bot detection, and web application firewall rules. Systematic attempts to extract data from Yellsy violate our Acceptable Use Policy and will result in immediate IP-level blocking and potential legal action.
