Privacy Policy


BIOMETRID, SA., NIPC 513 560 270, headquarters at Rua Paulo Gama 629, 4050-589 Porto, herein as “Biometrid”.


Introduction This privacy policy governs the User’s (“User”, “Biometrid User”, “You”) use of this website [ ] (“Biometrid App”, “Application”), created by Biometrid (“Biometrid”, “We”, “Us”) for the website [ ] and served by Biometrid and governs the privacy of the users who choose to use it.

Biometrid may change this Policy at any time and without notice, effective upon the posting of the revised Policy. Your continued use of the website and store shall be considered your acceptance of the revised Policy.


When we provide authentication and identification solutions to our clients, we are acting on their behalf as their service provider and processor. 

Our clients, and not us, are the controllers of the data you submit when interacting with our Authentication and Identification Services. 

For additional information about how your specific data is being collected and used, please review the privacy policy of our client who is using our Services with you.

In order to verify identity, Biometrid needs to collect information about our client’s users. The information collected is determined by the check and process that is being performed: (1) for online authentication, Biometrid requires an id/username and a picture or video of the user’s face. The information collected is used to verify that the person from the photo or video is the same as the one in the id/username; (2) to verify an ID document/Passport, we need to receive a photo of the document verified and a live photo of the person that is being verified. Biometrid will assess if the person from the live photo is the same as the one in the document; (3) for online 1:1 identity verification (face, liveness and id document/passport) will need to record a video conference between the client’s agent and user.

The case (1) explained above, it is done by storing an id/username of the user, and a generated ecrypted version of the biometric template from the image provided. We are using deep learning models that create a biometric template that cannot be reversed to the original image. The original image of the user is deleted after the biometric template is generated. After the first time use (the registration/enrollment process), every new authentication request, will require a new photo of the user, that will generate a new biometric template. The new biometric template is then compared with the original template to asses if it is a match. A match between the two templates means the user is the person it claims to be.

For the case (2) described above, our proprietary machine learning algorithm is verifying the autheticity of the ID document/Passport photographed. This is done by verifying the security elements present on the document (document size, presence of holograms, data corespondence between MRZ data and non-MRZ data, etc.).  After the authenticity is established, the ownership is being verified. In order to verify ownership of the document, Biometrid is assesing if the person from the live photo is the same as the person in the document photographed. When both the autheticity and document ownership are confimed, the photos collected are deleted.

In the case (3) mentioned above, the user is invited in a videoconference call with our client’s agents. The call is being recorded and has the purpose of attesting the user’s identity and contentment.

We do not store any user photos. 

If the user explicitly submits additional information, we may collect it at the request of our clients (name, email address etc.).

Biometrid limits its requests for information to what is required to ensure accurate service. When you install our app, to register you face and voice biometrics for strong identification, validation and authentication, your personal information will be encrypted and minimised by default and shared via secure (encrypted) means with third-party engines that helps our technology function. This allows us to process and fulfil your data safely. It also helps us in maintaining your account. Examples of user information that may be collected may include, but are not limited to, your name, address, e-mail address, data through the user’s IP address and face and voice biometrics. Polygon app was built for research and development of biometric solutions and its use requires the users consent, if you don’t accept the terms and conditions you should abstain off downloading our app.

Biometrid will share your personal information internally with those staff members who need it to carry out the research program. We will not disclose your personal information to any third party without your written consent unless required to do so by law.


Biometrid performs services on behalf of our clients for different reasons. The reasons are set by our clients, and we depend on them to inform us when they do not need to store the information we collected on their behalf. We delete the information we have collected about our users, when our clients instructs us to do so, thorough an agreement or an ad-hoc request.

If a user would like to have his information deleted, he is instructed to make a request directly to the client that carried out the related check. In the case the user registered directly with Biometrid, the request is made then with us. For more instructions about how to do this , please see below under “Your Rights”.

In cases we have a legitimate legal reason, we may store information for longer than described above – for example, where we are under a binding legal order not to destroy information.
