Software Licenses

Major parts of RuuviTag’s firmware and mobile applications are licensed with BSD-3. For more accurate information, visit our GitHub.

With the BSD-3 clause, you will not be required to divulge your source code, nor the source code of the open source libraries. It’s a very lenient license and as such does not require you to give permission to your users to re-distribute the binaries.

You are, however, expected to display any copyright statements from the BSD libraries, and you must also display the BSD license text where it makes sense to do so. For example, if your software is an application, you may include this information in an “About this Software” section. Alternatively, software documentation is another good place where this text may be added.

Example 1

Bosch Connected Industry is using RuuviTags as part of their logistics 4.0 solution Nexeed Track and Trace. They have publicly mentioned RuuviTag on their website. The project is also covered on the Ruuvi Node press release by Nordic Semiconductor.

Example 2

Kaltio Technologies is using RuuviTags as part of their tracking product - Smart Tracker. The devices are purchased from Ruuvi, but they have custom color enclosures and the customer’s own sticker on top. The original Ruuvi certification sticker, however, remains on the bottom of the device. On their marketing material, they mention RuuviTag.

Example 4

A hypothetical company purchases original RuuviTags from Ruuvi Innovations. They download Ruuvi’s online marketing materials in order to change RuuviTag’s name to something different.

This cannot be done, because using or altering Ruuvi’s marketing materials without a written permission from Ruuvi Innovations is prohibited.
