At Only Once you are not the product.
We restore online trust.


Privacy violations and data protection are daily news items. Our online privacy and personal data  are often not taken very seriously. Your data is highly valuable, we know. You know. Our data is traded without the data owners being asked. Internet fraud is rapidly increasing. We do not have certainty about internet users ID’s. Only Once’s intention is to stay a ‘advertising free’ platform. Online trust should be restored. That’s our ambition and mission.

Anywhere, anytime, anyplace and from any device

Our Life Management Platform can be used on any device and is developed crossplatform, scalable and lightweight.
Share you data where ever you are.
