Terms of Use

These terms apply to GRKU and to grku.app. When you install or use GRKU, you accept these terms. If you do not accept them, do not install GRKU.

Experimental software

GRKU is free, open-source software under the MIT License. The effects have their own licenses. GRKU is experimental. Ricoh does not make, support, or endorse GRKU.

GRKU runs from the SD card. It changes the camera only until the camera turns off, and it does not write the firmware. The installation turns on the SD script setting of the camera. This setting stays on until you turn it off.

Risks

• If GRKU fails, the camera can stop during startup. The recovery guide tells you how to start the camera again. Read it before you install.
• On a camera or a firmware version that was not tested, GRKU can fail or work incorrectly.
• Ricoh may decline warranty or repair service for a camera that used third-party software.
• Before you install or update GRKU, copy your photos from the SD card.

Fast-boot firmware

• If the update stops, or if the fast-boot firmware fails, the camera may not start. The recovery guide may not help in that case.
• The fast-boot firmware was tested on a GR III only. On another camera, it can fail.
• Ricoh may decline warranty or repair service for a camera that used modified firmware.
• You install the fast-boot firmware at your own risk. The sections below apply to it as they apply to GRKU.

No warranty

GRKU and grku.app are provided "as is", without warranty of any kind. The authors do not promise that GRKU works on your camera, that it has no errors, or that photos look as the preview shows.

Limitation of liability

You use GRKU at your own risk. To the maximum extent that the applicable law permits, the authors are not liable for damage to the camera or the SD card, for lost photos or data, or for other loss that comes from the use of GRKU or grku.app. These terms do not exclude a liability that the applicable law does not permit to exclude.

Trademarks

GRKU is not affiliated with or endorsed by Ricoh, Kodak, Fujifilm, or Ilford. Some camera, film, and paper names are trademarks of their owners.

Changes

These terms can change in a later version of GRKU. The current terms are on this page. If a translation differs from the English text, the English text applies.
