Privacy Policy

Who we are

Eurostar Snap Checker (“we”, “us”, “our”) is an independent availability monitoring service. We are not affiliated with, endorsed by, or connected to Eurostar International Limited in any way.

What data we collect

When you create an account or sign up for alerts, we collect:

• Email address — to authenticate your account and send availability notifications
• Name — if provided during registration or via Google sign-in (optional)
• Google account ID — if you sign in with Google, to link your account
• Password — if you create an account with email and password (stored securely hashed, never in plain text)
• Route preference — your selected origin and destination
• Date range — the travel dates you want to monitor
• Weekday preferences — which days of the week you prefer (Pro plan only)
• Passenger count — number of travellers

Payments

If you subscribe to the Pro plan, payment is processed entirely by Stripe. We do not store your card number, bank details, or any payment credentials on our servers. We only store a Stripe customer ID and subscription ID to manage your account tier.

Stripe’s privacy policy applies to all payment data: stripe.com/privacy.

How we use your data

Your data is used to:

• Authenticate and manage your account
• Check Eurostar Snap availability for your selected routes and dates
• Send you email alerts when matching dates become available
• Send you a confirmation email when you set up an alert
• Manage your subscription tier (Free or Pro)

We do not sell, share, or transfer your personal data to any third parties for marketing purposes.

Third-party services

• Stripe — payment processing for Pro subscriptions

Each service has its own privacy policy and processes data in accordance with GDPR.

Data storage and security

Your data is stored in a PostgreSQL database hosted by Neon in the London (UK) region. Passwords are hashed using bcrypt and never stored in plain text. All data is encrypted in transit via HTTPS. Authentication sessions are managed using secure, signed JSON Web Tokens (JWT).

Data retention

Your account and alert data is retained for as long as your account is active. When you unsubscribe from an alert, it is deactivated. You can request complete deletion of your account and all associated data by contacting us.

If you cancel a Pro subscription, your account reverts to the Free plan. No data is deleted upon cancellation.

• Access the personal data we hold about you
