VaccineChecking is committed to protecting your privacy. This policy explains how we collect, use, and safeguard your personal information when you use our travel health advisory service.

We collect information to provide and improve our service:

• Account Information: Email address, name, and authentication credentials
• Travel Information: Saved trips, destinations, and travel dates (for premium users)
• Health Records: Vaccination records you choose to store (encrypted, premium users)
• Usage Data: Pages visited, features used, and general app interactions
• Payment Information: Processed securely through Stripe (we do not store card details)

We use your information to:

• Provide travel health recommendations and vaccine information
• Send alerts about destination requirement changes (if you enable notifications)
• Process payments for premium subscriptions
• Improve our service through anonymized usage analytics
• Ensure security and prevent fraud
• Comply with legal obligations
• Provide customer support and troubleshooting

We only share your information with trusted service providers who help us operate:

• Payment Processing: Stripe (for billing and subscriptions)
• Email Delivery: Postmark (for notifications and alerts)
• SMS Delivery: Twilio (for SMS alerts, if enabled)
• Hosting & Infrastructure: Cloud service providers for secure data storage
• Analytics: Anonymized usage data for service improvement

All service providers are contractually obligated to protect your data and use it only for the services we request. We may also disclose information when required by law, court order, or to protect our rights and safety.

VaccineChecking may display affiliate links to travel-related services such as travel insurance, health clinics, and travel health products. When you click these links and make a purchase, we may earn a commission at no additional cost to you.

Important clarifications:

• We do NOT sell your personal information. Earning affiliate commissions does not mean we sell, rent, or share your personal data with partners.
• No Personal Data Sharing: We do NOT share your personal information with affiliate partners
• No Advertising Profiles: We do NOT build user profiles for targeted advertising
• Aggregate Metrics Only: We track click/impression counts at the ad level for performance measurement. We do not intentionally store ad-click PII (like name/email) for this purpose.
• Security Logs: Like most services, our infrastructure may temporarily process IP/device info in security logs to prevent fraud/abuse; we do not use this for advertising profiles.
• Third-Party Privacy Policies: Once you click an affiliate link and leave VaccineChecking, the partner site's privacy policy applies. We are not responsible for their data practices.

Affiliate partner sites may use their own cookies/trackers under their privacy policies once you leave VaccineChecking.

All affiliate links are clearly disclosed with FTC-compliant notices. You are never required to use affiliate links, and using them does not affect the quality of service you receive from VaccineChecking.

We implement industry-standard security measures:

• Encryption of sensitive data at rest and in transit (HTTPS/TLS)
• Encrypted storage for vaccine records and sensitive health information
• Access controls and least-privilege principles for our team
• Regular security audits and monitoring
• Secure authentication with optional two-factor authentication (2FA)

While we take reasonable precautions, no system is 100% secure. We encourage you to use strong passwords and enable 2FA for additional protection.

We retain your data while your account is active and for a reasonable period afterward to comply with legal obligations and resolve disputes. You may request account deletion at any time, and we will remove your personal information typically within 30 days (backups may be retained briefly for disaster recovery).

Our AI Travel Health Assistant uses third-party AI technology to answer your travel health questions. When you use this feature:

• No PII Sent: We do not send your email, name, or other personally identifiable information to AI providers
• Anonymized Context: Premium users may have trip destinations included for personalization, but without personal identifiers
• Data Processing: AI providers process queries to generate responses. We minimize what is sent and do not include direct identifiers. Data retention (if any) is governed by provider policies and our configuration; we do not use your AI queries to build advertising profiles.
• Optional Feature: Use of the AI assistant is entirely optional; you can browse manually without it

The AI assistant is for informational purposes only and is not a substitute for professional medical advice.

We use minimal necessary cookies to maintain your login session and remember your preferences. We collect anonymized usage analytics to improve our service, but we do not use tracking cookies for advertising purposes.

You have the right to:

• Access: View and download your personal data
• Update: Correct inaccurate information through your profile settings
• Delete: Request account and data deletion
• Export: Receive a copy of your data in a portable format
• Unsubscribe: Opt out of alerts and promotional emails at any time
• Withdraw Consent: Stop using our service and delete your account

To exercise these rights, please contact us using the information below or use the account settings in the app.

VaccineChecking is an informational service and does not provide medical advice. All health decisions should be made in consultation with qualified healthcare professionals.
