Terms of Use
LAST UPDATED · 28 AUGUST 2026
By installing or using FMC Keyboard (“the app”), developed and operated by Melih FIRAT, you agree to these terms. The current version is always available at cdu.fmckeyboard.com/terms.
Purpose
The app reproduces the alphabetical keypad layout of an aircraft Control Display Unit as an iOS keyboard for familiarisation and training. It is not a flight instrument, is not certified for any operational use, and is not affiliated with, endorsed by or connected to The Boeing Company or any airframe or avionics manufacturer. Trademarks belong to their owners.
Licence
We grant you a personal, non‑transferable, non‑exclusive licence to use the app on Apple devices you own or control, in accordance with the Apple Media Services Terms and Conditions.
Unlocking the keyboard
The keyboard is unlocked by a single in‑app purchase processed by Apple,
Unlock Forever (product identifier
fmc_keyboard_unlock_forever). It is a one‑time, non‑renewing
purchase. There is no subscription, nothing is billed again, and there is nothing to
cancel.
The price is shown in the app before you buy. Refunds are handled by Apple under its policies. The unlock can be restored on any other device signed in with the same Apple ID.
Acceptable use
You may not reverse‑engineer, resell or redistribute the app, or use it to violate any law.
Availability and changes
We may update, change or discontinue features at any time. We aim to keep the app working with current iOS versions but do not guarantee uninterrupted availability.
Disclaimer
The app is provided “as is” without warranties of any kind. To the maximum extent permitted by law we are not liable for any loss or damage arising from its use, including anything typed with the keyboard.
Governing law
These terms are governed by the laws of the Republic of Türkiye, without prejudice to mandatory consumer rights in your country of residence.
