Privacy Policy

Last updated October 28, 2026

Chocks Logbook ("Chocks") is made by CrisJet Aviation. This policy explains what the app does with your information.

Your logbook stays with you. Flights, aircraft, certificates, medical, documents, photos, PDFs, signatures, duty records and settings are stored on your iPhone, encrypted by iOS while the phone is locked. CrisJet Aviation does not run servers that receive your logbook and cannot see it.

iCloud backup and sync. Your logbook is backed up to, and synced between your devices through, your own private iCloud database using Apple's CloudKit. Only your Apple ID can read it. Backup files you create are saved wherever you choose.

Pilot profile (optional). If you turn on your Chocks Profile, the fields you choose — such as your name, photo, base, certificates and type ratings (without numbers), flight hours, currency status and availability — are stored on CrisJet Aviation's server and shown on a public page at crisjet.com/p/your-name. Certificate, medical and document numbers, your date of birth, address, email and phone are never published. Messages sent to you through your profile are delivered in the app without revealing your email. Turning the profile off or deleting your account removes it from the server.

Sign in with Apple. Used to identify your account. Apple shares a user identifier and, if you allow it, your name and email (which can be a private relay address).

Subscription. Purchases are handled by Apple through the App Store. We do not receive your payment details.

Camera and photos. Used only when you take or choose a picture of the FMS or a document. FMS text is read on your iPhone; images are not uploaded.

Location (optional). Used only when you start or end a duty or tap the location button, to find the nearest airport. Only the airport code is saved; your position is not stored or shared.

Logbook digitization (optional). If you ask CrisJet Aviation to type your paper logbook, the scans you choose are sent by email to digitize@crisjet.com. They are used only to create your logbook CSV — transcribed with the help of AI (Anthropic's Claude) and checked against each page's totals — and are deleted after delivery. Nothing is sent unless you request it.

Notifications. Reminders are scheduled on your iPhone.

No tracking. Chocks has no advertising and does not track you across apps or websites. We do not sell or share personal data.

Anonymous usage data. To improve the app, Chocks counts which features are used — for example "a flight was saved", "a report was opened" or "the free trial started" — using TelemetryDeck, a privacy-focused analytics service. These signals never include your name, email, flights, aircraft, airports, times, documents or location, and they are not linked to your identity: TelemetryDeck receives only a one-way hashed identifier that cannot be reversed. You can turn this off at any time in Chocks › Settings › Privacy › Share anonymous usage data.

App statistics and crash reports. CrisJet Aviation sees only the anonymous, aggregated statistics Apple provides through the App Store (downloads, active devices, subscriptions) and crash reports — and only if you chose to share analytics with app developers in your iPhone's Settings › Privacy & Security › Analytics & Improvements. These never include your logbook, documents or location.

Deleting your data. Deleting your account in Pilot › Settings › Account erases the logbook on this iPhone and the iCloud backup. Deleting the app also removes local data.
