Terms of Use

Last updated October 26, 2026

These terms apply to Chocks Logbook, made by CrisJet Aviation.

A tool, not an authority. Chocks helps you keep your logbook and calculate currency, duty and flight-time limits. It does not replace the regulations, your operator's manuals, your training program or your own judgment. You are responsible for the accuracy of your records and for complying with 14 CFR and any other rules that apply to you. Always verify before you fly.

Your records. You own your data. Keep backups. CrisJet Aviation is not responsible for loss of data or for decisions made using the app.

Regulatory compliance is your responsibility. Chocks is an aid, not a substitute for your own knowledge of the rules. Its calculations and alerts (currency, recency, duty, rest and flight-time limits, experience totals, report and form values) may be incomplete, outdated or wrong, and may not reflect your operator's approved programs, exemptions or the latest regulations. You must verify every entry and result against the official regulations and your operator's manuals before you rely on it. CrisJet Aviation is not responsible for any violation, enforcement action, certificate action, fine, penalty, loss of employment, or any other consequence that results from relying on the app, in whole or in part, including errors in the app.

Subscription. Chocks Pro is an annual auto-renewing subscription sold through the App Store, with a free trial for new subscribers. It renews unless cancelled at least 24 hours before the end of the period; manage or cancel it in your Apple ID settings. If the subscription ends you can still view and export your logbook.

Acceptable use. Do not misuse the app or try to access other users' data.

No warranty. The app is provided "as is". To the extent permitted by law, CrisJet Aviation is not liable for indirect or consequential damages arising from its use.

Changes. We may update these terms; the date above shows the latest version.
