Gemma 4 Responsibility Guidelines

PhotoLens runs Google's open-weight Gemma 4 model entirely on your device. Here is how it is used, what it is good at, and where it should not be trusted.

Gemma Responsibility Guidelines

PhotoLens is powered by Google's open-weight Gemma family of models. The three documents below — the Prohibited Use Policy, the License, and the Intended Use Statement — are reproduced here from Google's official Gemma documentation. They govern how the Gemma model and any model derivatives may be used, both inside PhotoLens and anywhere else.

          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution

      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,

      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

Users are responsible for complying with all legal and regulatory requirements applicable to their specific applications and use cases.

Product Description

Gemma empowers developers and researchers to create bespoke solutions by training and fine-tuning models with their own data, controls, and domain-specific knowledge. This allows developers and researchers to create customized AI solutions tailored to specific tasks and industries.

For example, users could potentially build products using Gemma to:

  • Tutor K-12 students in mathematics.
  • Create personalized trip planning applications.
  • Analyze, label, or caption images.
  • Generate reports based on medical data.
  • Assist with administrative tasks in healthcare settings, such as summarizing notes or scheduling appointments.
  • Develop tools for home finance management and analysis.
