GR Tools is an independent project. Ricoh does not sponsor, endorse, or support it.
Copyright (C) 2026 BangBOOM and GR Tools contributors. Studio uses AGPL-3.0-only. Firmware uses GPL-2.0-only for its combination with Unicorn, under the alternative grant for original Firmware components. Both licenses require corresponding source for distribution. Modified Studio versions with remote network interaction must also offer source to those users.
Your original LUTs, Style configurations, and photos remain yours. Using the tools does not require you to publish them or license them under AGPL. Third-party components, reference styles, and firmware-derived assets keep separate terms.
The software is provided as is. Its license grants no rights to Ricoh firmware and does not guarantee protection from legal claims. Firmware updates can damage a camera or affect saved settings and old DNG rendering. Offline checks do not establish camera safety; every new candidate requires device acceptance.
