✈ Logbird

1. Overview

Logbird ("the app") is a personal aviation logbook application for iOS. It is designed for commercial and private pilots to record flight hours, track regulatory currency, monitor fatigue time limits, and manage licence documents.

This Privacy Policy explains what information the app accesses, how it is handled, and your rights regarding that information.

2. Data we do not collect

Logbird does not collect, transmit, or store on any external server:

• Your name, email address, or any contact information
• Flight records, routes, times, or logbook entries
• Licence numbers, document expiry dates, or medical certificates
• Device identifiers (IDFA, IDFV, or similar)
• Location data
• Usage behaviour, session length, or screen analytics
• Crash reports or diagnostic data
• Any data that could be used to identify you personally

3. Data stored on your device

The app stores the following data locally on your device only, using WebKit's IndexedDB and localStorage APIs within the WKWebView sandbox:

Flight logbook data

• Flight records: dates, routes, times, aircraft registrations, crew names you enter, remarks
• Simulator session records
• Duty period logs

Crew member information

When you log flights, you may enter the names of other crew members (captain, first officer, relief pilots, cabin crew) and personal notes about them. This information is stored only on your device and is never transmitted to us.

Crew names and notes may be included in exports (JSON, CSV, XLSX) unless you enable the "Exclude crew names & notes" option when exporting. You are responsible for handling exported files that contain other people's personal information in accordance with applicable data protection regulations.

App settings and preferences

• Pilot profile (name and licence number you type in)
• Airline/operator selection and fleet configuration
• Currency rules, FTL limits, and display preferences

Document tracker

• Licence and document names and expiry dates you enter manually

All of this data is contained within the app's private sandboxed storage. It cannot be read by other apps and is deleted when you delete Logbird from your device.

4. Network requests

Logbird bundles all JavaScript libraries (Chart.js, SheetJS, jsPDF, Leaflet) locally within the app. The only network requests the app makes are:

Web fonts

The app uses system fonts only — San Francisco (SF Pro Text), the iOS default UI font, with SF Mono for monospaced text and New York for serif text. These fonts ship with iOS and are never fetched from a third party. No font requests are made to any external service, including Google Fonts.

Map imagery

The Map and Route Analytics pages make no network requests at all. The world map is drawn by the app from coastline geometry bundled inside it (Natural Earth, public domain), not fetched from a tile server. Earlier versions loaded tile images from a third party, which disclosed your device's IP address to that provider; that is no longer the case, and any tiles those versions cached on your device are deleted the first time you open the map.

If you do not use Roster Sync, and iCloud backup is unavailable or disabled on your device, the app makes no outbound network requests at all and operates fully offline.

iCloud sync (optional)

If you choose to back up your logbook via iCloud, data is transmitted to Apple's iCloud servers under your Apple ID. This is governed by Apple's Privacy Policy. Logbird does not operate any intermediate servers — the sync is directly between your device and Apple's infrastructure.

Roster auto-sync (optional)

If you paste your airline crew portal's ICS subscription link into Roster Sync, the app fetches that URL directly — each time you open the app, and when you tap "Refresh now" — to pull new roster entries into your logbook. This is an opt-in feature: nothing is fetched unless you provide a URL yourself.

That URL typically contains an access token issued by your airline, which grants read access to your roster. Because of that:

• The URL is sent, as pasted, to your airline's own server on every sync — Logbird does not proxy or log this request through any server of its own.
• The URL is stored locally in the app's settings, and is included in your iCloud backup and in any full JSON export you create — treat those backups and exports with the same care as the URL itself, since anyone who obtains it can read your roster until the token is revoked or expires.

Disabling Roster Sync or deleting the URL from Settings stops all future fetches and removes it from any backup taken afterward, but does not retroactively remove it from backups already made.

5. Data export and sharing

The app provides export functionality so you can back up and move your logbook data:

• JSON export — logbook backup in open format; People-page photos are stored only on this device and are not included
• CSV export — spreadsheet-compatible format
• XLSX export — multi-sheet Excel workbook with stats
• EASA/FAA PDF logbook — formatted print-ready logbook

Exports are delivered directly to your device through the iOS Share Sheet (Files app, AirDrop, email, etc.). Logbird does not transmit export files to any server. You choose where your exports go.

Exports may contain crew member names from your flight records. You can enable "Exclude crew names & notes" in the export screen to strip all third-party personal data before sharing.

6. Roster import

The app can import roster data from ICS calendar files or pasted roster text. This data is processed entirely on-device and stored in local app storage. Roster files are not uploaded to any external service.

7. Children's privacy

Logbird is intended for use by licensed pilots and aviation professionals. It is not directed at children under 13. We do not knowingly collect personal information from children. Because no data is collected by us from any user, this policy applies equally to all age groups.

8. Your data, your control

Because all data is stored locally on your device, you are in complete control at all times:

• Delete all data — use the "Clear All Data" option in Settings → Data Management, or delete the app from your device
• Export your data — use the Export page at any time to get a full copy
• Import data — restore from a previous export on any device with Logbird installed

There is no account to delete and no server-side data for us to erase — because we never had it.

9. Changes to this policy

If we ever update this Privacy Policy, the revised version will be published at this URL and the "Last updated" date at the top of this page will change. For material changes, we will notify users through an in-app notice on the next app launch.

Given the fundamental nature of Logbird (no server-side data collection, only the limited outbound traffic disclosed in Section 4), any changes to data practices would require explicit user consent and an app update reviewed by Apple.
