• Google sign‑in: a stable user identifier and basic profile data provided by Google (typically email and display name) for authentication.
• Analytics (Amplitude): usage events (screens, taps, feature usage), basic device/OS info, language, and performance metrics.
• Server logs: timestamps, endpoints, diagnostics and error messages; IP address may be logged for security and abuse prevention.
• Crash logs: server‑side crash diagnostics and stack traces related to requests.
• User input: flight number and date (to build requests).

• No GPS location (not collected).
• No push tokens (push notifications are not used).
• No payment details (no payment system yet).

• Provide app functionality and show results.
• Maintain reliability and performance; debug issues.
• Protect the service (rate limiting, abuse detection, security investigations).
• Improve the product based on aggregated usage patterns.

Technical logs may be retained indefinitely. We do this to investigate incidents, maintain long‑term stability, and improve security. If you request deletion or anonymization, we will evaluate it where legally and technically possible.

We may share data with service providers necessary to run the App:

• Amplitude (analytics events).
• Google (authentication).
• Infrastructure providers (hosting, monitoring, CDN) to deliver the service.

We do not sell personal data.
