Built for pilots who care
about their data.

Multi-License Management

Hold a PPL and SPL? EASA and FAA? NinerLog handles them all. Flights count toward all applicable licenses and class ratings automatically.

• Any regulatory authority worldwide
• Class ratings with expiry tracking (SEP, MEP, TMG, IR)
• No per-license flight assignment — flights count everywhere

Import

Switching from another logbook? Bring your data in. NinerLog maps your existing flights automatically — no manual re-entry.

• Import from CSV and XLS
• Automatic field mapping and validation

Cloud Backup

Send a copy of your logbook to a cloud storage location you own and control — on a schedule, automatically. Point NinerLog at any S3-compatible bucket you trust, and we’ll keep an offsite copy of your flights there for you. S3-compatible storage is the only destination today, with more providers on the way — no NinerLog-only vault, no lock-in, just your data in your storage.

• You pick the destination. Bring your own S3-compatible bucket — NinerLog never holds the only copy
• Truly user-owned. The backup files sit in your storage account under your credentials — you can read, copy, or delete them without us
• Open formats. Backups use the same CSV / JSON your export already produces — readable with or without NinerLog
• Opt-in and reversible. Off by default, switch on when you want it, disconnect any time — we keep no copy of your storage credentials beyond what’s needed to run the backup
• Scheduled, offsite, automatic. A second copy lands safely outside the app on the cadence you choose — daily, weekly, or after every flight
• Restore from your own files. Bring a backup file back into NinerLog at any time — or open it directly in a spreadsheet

Cloud backup is entirely optional — the rest of NinerLog works exactly the same with it switched off. See our privacy policy for how connection details are handled.

Login Security

Your logbook is years of flying history — we treat it that way. NinerLog protects your account with modern, phishing-resistant sign-in: add a passkey from your phone, laptop, or hardware key, or turn on two-factor authentication with the authenticator app you already use. Available on both the hosted version and any self-hosted instance.

• Passkey sign-in. Use Face ID, Touch ID, Windows Hello, or a security key — no password to phish, no password to forget
• Two-factor authentication. Pair your password with any standard TOTP app — Aegis, 1Password, Google Authenticator, you name it
• Recovery codes. Print or stash one-time backup codes so you’re never locked out of your own logbook
• Hosted or self-hosted. Strong sign-in works the same on app.ninerlog.com and on your own Docker instance — no extra services required
