Utilize Personal Sensor and Wearable Data Without Sharing


​How is that possible?

Personal data is organized in the user's personal data cloud. 
​
Prifina builds the personal data layer and engine for developers to create new applications by combining data sources and types.

Applications run on the user's side. Data stays in the user's personal cloud and generates value for the user. Neither Prifina nor developers can access user data in any way.

No servers, no logs. Applications do not communicate externally.

To build apps, Open Source Dynamic Data Generators data available on Github and more tools and utilities are available on Prifina's GitHub. - Learn more...

​You can use our tools locally with your data, and you can sign up for more free tools on the Prifina platform.

Prifina's platform is gradually opening. Get involved on Slack.
