By downloading or using Derrick ("the App"), you agree to these Terms of Use. If you do not agree, do not use the App.
Evelaina grants you a personal, non-exclusive, non-transferable, revocable license to use the App on Apple devices you own or control, for your own personal use, subject to these Terms and the Apple Media Services Terms and Conditions.
Derrick is a personal planning tool that takes the rotation schedule you enter and shows you your hitch status, countdowns, upcoming crew-change dates, and pay estimates. It is a convenience aid for organizing your own schedule.
⚠️ Estimates only — confirm with your employer. Derrick's schedules, countdowns, dates, and pay figures are planning estimates generated from the rotation you enter. They are not an authoritative schedule or a paystub. You are responsible for confirming your actual work schedule, crew-change dates, and pay with your employer. Derrick is not liable for missed shifts, missed travel, or pay discrepancies arising from reliance on its estimates. Do not rely on the App as your sole source of truth for when you are on or off — always verify against your employer's official schedule.
Derrick Pro is an optional one-time, non-consumable in-app purchase (approximately $29.99 USD; prices may vary by region and current pricing is shown in the App). It permanently unlocks the Pro features on your Apple Account. It is not a subscription — there is no recurring charge and nothing to cancel.
You agree not to:
You retain ownership of the data you enter (rotation, dates, pay settings, My Crew imports). That data remains stored on your device. Beginning with version 1.4.0, Derrick sends limited app-activation, product-interaction, and verified-purchase event data to Meta for advertising attribution and analytics, while Apple processes App Store purchases. Apple's App Tracking Transparency setting controls advertiser tracking. The Privacy Policy explains the data categories, purposes, controls, retention, and deletion options and forms part of these Terms.
The App's design, code, and implementation are owned by Evelaina. You may not copy, modify, or distribute the App itself without written permission.
The App is provided "as is" and "as available" without warranties of any kind, express or implied, including but not limited to merchantability, fitness for a particular purpose, and non-infringement. We do not guarantee that the App will be error-free or uninterrupted, or that any schedule, date, countdown, or pay estimate it produces will be accurate or match your employer's records.
To the maximum extent permitted by law, Evelaina shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of the App, including but not limited to missed shifts, missed travel, lost wages or pay discrepancies, scheduling errors, or loss of data due to device failure or App deletion.
We may update these Terms from time to time. Continued use of the App after changes constitutes acceptance of the updated Terms. The revised version will be posted at this URL with a new "Last updated" date.
These Terms are governed by the laws of the jurisdiction in which Evelaina operates, without regard to conflict-of-law principles.
