1. Information We Collect

Account Information: When you create an account, we collect your email address and display name.

Trip Data: Information you provide about your trips, including destinations, dates, itineraries, activities, expenses, and group members.

1.5 Atlas AI & Third-Party AI Services

Atlas Powered by Claude AI: Stamp'd uses Atlas, an AI travel concierge powered by Claude, an AI model developed by Anthropic, Inc. Atlas generates trip suggestions, itineraries, packing lists, travel advice, and helps with group decision-making.

• What Data Is NOT Sent: Your personal data (email address, full name, payment information, phone number) is never shared with Anthropic. We only send trip planning details.
• Data Sent to Anthropic: When you use Atlas features, we send your trip data (destination, travel dates, budget, group size, interests, home airport) to Anthropic's servers for processing. This data helps Claude generate personalized recommendations.
• Anthropic's Privacy Practices: Anthropic's use of your data is governed by their privacy policy: anthropic.com/privacy. Anthropic may retain processed data according to their retention policy.
• Attribution: Atlas features are powered by Claude AI (Anthropic). Our use of Claude is subject to Anthropic's terms of service.
• Opt-Out: You can disable AI features anytime in Settings → Privacy & AI. Disabling AI features prevents your trip data from being sent to Anthropic.
• Accuracy Disclaimer: Claude-generated suggestions are for informational purposes only and may not be fully accurate. Always verify important travel details (visa requirements, entry restrictions, safety, pricing) through official government, tourism, or airline websites before making decisions.
• EU Users (GDPR): Your trip data may be transferred to and processed in the United States when using Atlas features. By using Atlas, you consent to this international data transfer under Standard Contractual Clauses with Anthropic.

3. Data Storage and Security

Your data is stored securely using Base44, our backend-as-a-service provider. We use industry-standard security measures to protect your personal information. Data is transmitted over encrypted HTTPS connections.

4. Third-Party Services

Stamp'd integrates with the following third-party services:

• Base44: Backend data storage and authentication.
• Viator: Activity and experience recommendations. Subject to Viator's own privacy policy.
• Expedia / Booking.com / Hostelworld: Accommodation and flight links. These are affiliate links that redirect to their platforms, which have their own privacy policies.

We do not share your personal data with these partners. Affiliate links redirect you to third-party sites where their own privacy policies apply.

5. Data Sharing

We do not sell, rent, or trade your personal information to third parties. Your data may be shared only in the following circumstances:

6. Data Retention and Deletion

Data Lifecycle: Your data is retained as long as your account is active. Below is a detailed breakdown of retention for specific data types:

• Stamps: Retained indefinitely until you delete the individual stamp or your account. Deleting a stamp removes the associated photos and location data immediately.
• Photos: Retained as long as the stamp, trip, or profile picture containing them exists. If you delete a stamp or trip, associated photos are deleted. Profile pictures are retained until you upload a new one or delete your account.
• Messages: Retained indefinitely within the trip group chat until you or another group member deletes the trip. Trip deletion removes all associated messages permanently.
• Trip Data: Retained until the trip is deleted. Organizer can delete trips at any time. When a trip is deleted, all associated data (itineraries, activities, expenses, member data, messages) is permanently removed.
• Account Data: Upon account deletion, all stamps, trips, photos, messages, payment history, and personal information are permanently deleted within 30 days. Data shared with group members remains in their accounts unless they delete the trip.
• Shared Trip Data: Share tokens and encrypted trip snapshots expire after 30 days. You can delete a share link anytime by removing the share in your trip.
