Privacy Policy

1. Information We Collect

Data	Source	Purpose
Apple ID email & name	Apple Sign In	Account creation & identification
Crew category, aircraft type, base	You (profile setup)	Filtering patterns to your eligibility
ARMS pattern book PDF	You (upload)	Parsing trip patterns for bid optimization
Bid briefs	You (free-text input)	AI-powered bid sheet generation
Bid sheets	Generated by the service	Optimization results for your review
Subscription status	Apple App Store	Access control and billing
Buddy link data	You (invite/accept)	Connecting you with another pilot for joint bid optimization

2. How We Use Your Information

• Bid optimization: Your bid brief and parsed pattern data are sent to Anthropic's Claude API to generate optimized bid sheets. No other purpose.
• Account management: Your Apple ID information is used solely for authentication and account identification.
• Subscription management: Subscription transactions are handled entirely by Apple via StoreKit 2. We store only your subscription status, not payment details.
• Buddy Bidding: When you link with another pilot, your name and crew category are shared with your buddy. During Buddy Sync, the backend reads both pilots' bid briefs server-side to generate buddy-aware bid sheets. Your buddy never sees your bid brief text, raw preferences, personal dates, email, or subscription status — only the resulting schedule overlap (matched patterns, shared slip days).

3. Third-Party Services

• Anthropic (Claude API): Bid briefs and parsed pattern data are sent to Anthropic's servers in the United States for AI-powered optimization. Anthropic's use of this data is governed by their privacy policy. Anthropic does not use API inputs to train their models.
• Apple: Authentication via Apple Sign In and payments via StoreKit 2. Governed by Apple's privacy policy.

We do not sell, rent, or share your personal information with any third parties. When you use Buddy Bidding, your name and crew category are shared with pilots you explicitly link with. You can remove a buddy link at any time from Settings, which immediately stops all data sharing with that pilot. We do not use analytics, tracking cookies, or third-party advertising services.

4. Data Retention

• Account data (email, name, profile): retained until you delete your account.
• Bid sheets: retained for 12 months, then automatically deleted.
• Uploaded PDFs: parsed server-side and not retained after parsing is complete. We do not store your pattern book files.
• Buddy links: retained until either pilot removes the link. Removed links are soft-deleted (status set to “removed”) and purged after 90 days.

5. Data Security

We protect your data using:

• TLS encryption for all data in transit
• JWT-based authentication with HS256 signing
• Server-side API key management (your device never holds AI service credentials)
• PostgreSQL with connection encryption
• Rate limiting and request size controls

6. Your Rights

• Access: You can view your profile data and bid sheets within the app at any time.
• Deletion: You can delete your account at any time from the app's Settings screen. This permanently removes all your data, including profile information, bid sheets, and optimization history. Account deletion is immediate and irreversible.
• Portability: Bid sheets can be viewed and copied from within the app.

7. Children's Privacy

BidCheck is designed for professional airline pilots. We do not knowingly collect information from anyone under the age of 18. If you believe a child has provided us with personal information, please contact us and we will delete it.

8. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of material changes through the app or by updating the "Last updated" date above. Continued use of BidCheck after changes constitutes acceptance of the updated policy.
