The WordPress Plugin Security Checker is provided to help WordPress users evaluate WordPress Plugins before they install on their website. By using this facility you agree to the these terms:
The results displayed provide the information we think that you will need to make your own conclusions. We do not provide an exhaustive investigation. There may be problems that our research has not uncovered. You should therefore not rely on our results but use your own judgment as to whether a plugin is appropriate. We hope that our assessments will help you in that process.
Accordingly, we make absolutely no guarantees. If we are wrong in our assessment you accept that you are not able to sue us for that reason.
If you object to any of our assessments, for example if you are a developer of a plugin we have listed then please contact us. We do not guarantee to change or remove anything merely on request.
