Privacy Policy

Last updated: April 21, 2026

This Privacy Policy describes how TailNumber ("TailNumber," "we," "us") collects, uses, and shares information when you use our mobile application (the "App").

Information we collect

• Email address — only if you choose to sign in. We use email one-time codes for authentication; we never store or see your password.
• Search history and saved aircraft (watchlist) — stored on our servers and associated with your account so you can access them across devices. Stored locally on-device if you don't sign in.
• Push notification token — if you enable alerts, the device token your phone uses to receive push notifications is stored so we can send you alerts about your saved aircraft.
• Purchase receipts — managed by Apple and our subscription provider (RevenueCat) when you subscribe. We receive a confirmation that you have an active subscription; we do not see or store your payment details.
• Aircraft registration data shown in the App comes from public FAA and NTSB sources. These lookups are queries against a public dataset; we do not tie them to personally identifying information unless you are signed in and saving them to your watchlist.

Information we do NOT collect

• We do not collect names, phone numbers, addresses, or location.
• We do not use third-party analytics trackers, ad SDKs, or advertising IDs.
• We do not track your activity across other apps or websites.
• We do not sell your data. Ever.

How we use your information

• To authenticate you (email OTP).
• To sync your watchlist across your devices.
• To send push notifications you've explicitly enabled.
• To verify your active subscription status.
• To detect abuse (e.g. rate-limit automated scraping of the App).

Third parties

We use the following service providers. Each of them has its own privacy policy governing data we share with them:

• Supabase — hosts our database (watchlist, email, push tokens).
• RevenueCat — manages subscription entitlements.
• Apple — processes payments and delivers push notifications.
• Expo / EAS — delivers over-the-air updates to the App (JavaScript bundles only, no user data is sent).

Public FAA and NTSB data

The aircraft registration, airman certificate, NTSB accident, and FAA Service Difficulty Report data surfaced in the App are published by the U.S. Federal Aviation Administration and the National Transportation Safety Board as part of the public record. We ingest these bulk datasets on a periodic schedule and serve them read-only through the App.

If you are an airman or aircraft owner and your record appears in these public datasets, you have the option to opt out of the FAA's Releasable database directly through the FAA — see FAA Releasable Airmen Database. Once you opt out at the FAA, your record will fall out of TailNumber the next time we re-ingest their files (usually within 30 days).

Your rights

• Access — email support@tailnumberapp.com and we'll send you a copy of everything associated with your account.
• Deletion — you can delete your account and all associated data from Settings → Account → Delete account in the App, or by emailing support. Deletion removes your email, watchlist, and push tokens from our systems within 30 days.
• Correction — email us and we'll update or correct any account information.

Children

TailNumber is not directed at children under 13, and we do not knowingly collect personal information from children under 13.

Changes

If we change this policy, we'll update the date at the top and, for material changes, notify signed-in users in the App. Continued use of the App after changes constitutes acceptance of the updated policy.
