We implement a number of mechanisms to make sure that data we collect remains secure. We use industry standard TLS encryption to secure data transfers from our browser extension and mobile apps to our servers. The computers that store collected data are housed in a secure datacenter that is only accessible to staff that hold special key cards. The computers that store collected data are hardened against common cybersecurity threats using industry standard software like firewalls. Access to collected data is limited to Observatory staff and approved researchers, and they may only access data after logging in with strong authentication credentials. Individual-level data will never leave our secure computers; researchers will only ever download aggregated data that has been de-identified. All accesses to our computers are securely logged.
