Information We Collect

When you interact with us through the Application, we may collect Personal Data and other information from you, as further described below:

Personal Data That You Provide Through the Application: We collect Personal Data from you when you voluntarily provide such information, such as when you contact us with inquiries, register for access to the Application or use certain Services.

The application requests access of the following sensors:

  • GPS: This is used to track your location and decide whether you are near (or in) a supported site. The GPS coordinates are not stored in your phone, nor in any external infrastructure, since they are used real-time.
  • Camera: The camera is used to on-demand scan for visual markers, in order to identify your location. No image is captured or stored in the device, and no image is being sent to any external infrastructure, since they are used real-time.
  • Each time you request a new navigation route, your coordinates, along with the coordinates of the target are sent to our cloud infrastructure, where the path is generated. This information is stored for statistical reasons, and under no circumstances it contains personal information that can correlate the navigation route, or the location with the physical device.

By voluntarily providing us with Personal Data, you are consenting to us using them in the context of the “Services” and in accordance with this Privacy Policy.

We may store such information in our infrastructure or such in databases owned and maintained by R4A’s affiliates, agents or service providers, located in the European Union. The Services may use such information and pool it with other information on an anonymized and generalized basis to track, for example, the total number of users of our Services.

Our Use of Your Personal Data and Other Information

By providing us with the information about you discussed above, you consent for us to use that information in the following ways:

  • to include your anonymized data in publicly available aggregated statistics
  • to use your anonymized data for scientific purposes (in research projects, scientific publications etc.)

Our Disclosure of Your Personal Data and Other Information

R4A is a research group and data capturing and processing is done for scientific purposes.

Legal Requirements: R4A may disclose your Personal Data if required to do so by law or in the good faith belief that such action is necessary to (i) comply with a legal obligation, (ii) protect and defend the rights or property of R4A, (iii) act in urgent circumstances to protect the personal safety of users of the Services or the public, or (iv) protect against legal liability.

Your Choices

You can visit the Services without providing any Personal Data. If you choose not to provide any Personal Data, you may not be able to use certain NavPin Services.

Where and how we store your personal information

The information that we collect from you will be held in servers in the European Union.


R4A does not knowingly collect Personal Data from children under the age of 16 without written parental consent. If you are under the age of 16, please do not submit any Personal Data through the Services, unless written parental consent has been provided. We encourage parents and legal guardians to monitor their children’s Internet usage and to help enforce our Privacy Policy by instructing their children never to provide Personal Data on the Services without their permission. If you have reason to believe that a child under the age of 16 has provided Personal Data to ISSEL through the Services without a submitted parental consent, please contact us, and we will endeavor to delete that information from our databases.

Links to Other Web Sites

This Privacy Policy applies only to the Services. The Services may contain links to other web sites not operated or controlled by R4A (the “Third Party Sites”). The policies and procedures we described here do not apply to the Third-Party Sites. The links from the Services do not imply that R4A endorses or has reviewed the Third-Party Sites. We suggest contacting those sites directly for information on their privacy policies.


R4A takes reasonable steps to protect the Personal Data provided via the Services from loss, misuse, and unauthorized access, disclosure, alteration, or destruction. However, no Internet or e-mail transmission is ever fully secure or error free; any transmission is at your own risk. In particular, e-mail sent to or from the Services may not be secure. Therefore, you should take special care in deciding what information you send to us via e-mail. Please keep this in mind when disclosing any Personal Data to R4A via the Internet. Once we have received your information, we will use strict procedures and security features to try to prevent unauthorized access.
