Who runs UDB, the licences it ships under, and whose names and images it shows.
Who runs UDB
UDB is made and run by Lorenz “Lanz” Malabanan, an independent developer in Batangas City, Philippines, as a personal open-source project. It isn't a company and sells nothing. More of my work is on lorenzmalabanan.com, including UDB's project page.
Questions, bugs and takedown requests go through the Contact page.
Licence
UDB is free software under the GNU General Public License, version 3 or later. Some protocol code is ported from projects under the GNU Affero General Public License 3.0, so the app hosted here is offered under AGPL-3.0 terms: the exact source of this build is linked from the foot of every page.
Third-party work
- OpenMouse (AGPL-3.0): ported device protocols and the ATK, Razer, SteelSeries and Logitech catalogues.
- libratbag (MIT, © Red Hat, Inc.): Logitech device list.
- HeadsetControl (GPL-3.0): Logitech headset product IDs and names.
- Fredoka (SIL Open Font License 1.1): the display typeface, served from this site.
Each one's licence and source are kept with the code, in the repository's third_party/ folder.
Names, trademarks and images
Product names, trademarks and product images belong to their makers. UDB isn't affiliated with, endorsed by or sponsored by any of them; a name or picture only identifies a product and never means it is supported. Each image's source is recorded in the repository. If you own an image and want it removed, ask through the Contact page and it will be taken down.
The UDB name, Dee the mascot and the app icon belong to their author.
Privacy and use
UDB collects nothing and uploads nothing; the Terms of use say what is kept in your browser, what the host may log, and what you accept when you write to a device.
