Frequently Asked Questions

Sheldon is your AI travel companion. It automatically detects trips from your email, organizes everything into clean itineraries, manages boarding passes across all airlines, and maps everywhere you've traveled — all from one app.

When you connect your Gmail or Outlook account, Sheldon scans for travel-related emails from airlines, hotels, car rental companies, and booking platforms. It parses confirmation details and creates organized trip itineraries automatically. You can also paste confirmation text manually.

Sheldon recognizes emails from 30+ travel providers including:

• Airlines: United, Delta, American, Southwest, JetBlue, British Airways, Lufthansa, Air France, Emirates, Qatar Airways, Turkish Airlines, Singapore Airlines, Japan Airlines, EgyptAir, Ryanair, EasyJet, and more
• Hotels: Marriott, Hilton, IHG, Hyatt, Booking.com, Expedia, Airbnb
• Car Rental: Hertz, Avis, Enterprise, Budget, Sixt
• Rail: Amtrak, Eurostar

We're adding more providers regularly.

Sheldon is currently available on iOS. Android support is on our roadmap — stay tuned.

Yes. Sheldon uses a local-first architecture, meaning your trips, boarding passes, and itineraries are stored on your device — not on our servers. We never have access to your personal travel data.

No. Sheldon only searches for emails from known travel providers (airlines, hotels, booking platforms) and emails with travel-related subject lines. Non-travel emails are never read, stored, or transmitted. We use OAuth 2.0, so we never see your email password.

Go to Settings in the app, find your connected email account, and tap Disconnect. This immediately revokes Sheldon's access to your email. You can also revoke access directly from your Google or Microsoft account security settings.

Go to Settings → Delete All Data. Since everything is stored locally on your device, this permanently removes all trips, boarding passes, and account data. Uninstalling the app also removes all data.

The world map tracks every country you've visited based on your trips. You can see stats like total countries visited, share your travel map with friends, and tap countries to see your trip history there. The map is available to all users for free.

Sheldon extracts boarding pass information from your email confirmations and displays them in Apple Wallet-style cards with QR/barcode support. All your boarding passes across every airline live in one place — no more juggling between airline apps. Boarding passes are a Sheldon Plus feature.

Yes. Tap the "Add Trip" button on the home screen and paste any confirmation email text. Sheldon will parse the details and create an itinerary. You can also manually edit any field after parsing.

Yes. Open any trip and tap the Share button to send a formatted trip summary to travel companions via text, email, or any sharing method on your device.

The free tier includes up to 5 trip imports, 1 connected email account, the world travel map, trip sharing, and the full timeline view. It's everything you need to get started.

Sheldon Plus unlocks unlimited trip imports, multiple email accounts, the boarding pass hub, PDF trip pack exports, and priority support. It's designed for frequent travelers who want everything in one place.

Sheldon Plus is $4.99/month. You can subscribe from the app and cancel anytime through your Apple ID subscription settings.

Open Settings on your iPhone → tap your name → Subscriptions → Sheldon World → Cancel Subscription. Your Plus features remain active until the end of the current billing period.

Subscriptions are managed by Apple. To request a refund, visit reportaproblem.apple.com and sign in with your Apple ID.

Parsing works best with standard confirmation emails from major travel providers. Some custom-formatted or forwarded emails may not parse perfectly. You can always edit any parsed field manually by tapping on it in the trip view.

Make sure your email is connected in Settings and the sync status shows as active. Sheldon searches for emails from known travel providers — if yours isn't recognized, try pasting the confirmation text directly. If the issue persists, contact support@sheldon.world.

Force-close the app and reopen it. If the issue persists, go to Settings and tap the header 7 times to access Diagnostics. You can view error logs there and email them to our support team for investigation.
