Data Usage FAQ

Does Google use the image I send to the Vision API?
Google does not use any of your content (such as images and labels) for any purpose except to provide you with the Vision API service.
Will Google share the image I send to the Vision API?
We will not make the image that you send available to the public, or share it with anyone else, except as necessary to provide the Vision API service. For example, sometimes, we may need to use a third-party vendor to help us provide some aspect of our services, such as storage or transmission of data, who will be under appropriate security and confidentiality contractual obligations. We will not share the image that you send with any other parties, or make it public, for any other purpose.
Will the image I send to the Vision API, the results or other information about the request itself, be stored on Google servers? If so, how long and where is the information kept, and do I have access to it?
When you send an image to Vision API, we must store that image for a short period of time in order to perform the analysis and return the results to you. For asynchronous offline batch operations, the stored image is typically deleted right after the processing is done, with a failsafe Time to live (TTL) of a few hours. For online (immediate response) operations, the image data is processed in memory and not persisted to disk. Google also temporarily logs some metadata about your Vision API requests (such as the time the request was received and the size of the request) to improve our service and combat abuse.
How does Google protect and ensure the security of the data I send to Vision API?
Please refer to the Google Cloud Platform Security page which describes the security measures in place for Google's Cloud Services.
Does Google use my data for improving Cloud Vision?
Currently, Google does not use the content you send to train and improve our Cloud Vision features such as its machine perception model.
Does Google claim ownership of the content I send in the request to Vision API?
Google does not claim any ownership in any of the content (including images and labels) that you transmit to the Vision API.
Can I resell the Vision API?
No, you are not permitted to resell the Vision API service. You can still integrate Vision API into applications of independent value.
