Essential metrics
All important statistics that help you to improve your service.
Filter collected data by URL, Location, Referrer, UTM parameters, as well as Landing Pages and Exit Pages.
Objectives
Privacy friendly
Collection of usage data is opt in, users that do not actively opt in will never leave a trace.
After opt in, Offen collects the minimal amount of data needed to generate meaningful statistics for operators.
No IPs, User-Agent strings or similar are being collected or even looked at.
Secure
Data in Offen is encrypted End-To-End.
Clients encrypt usage data before it leaves the browser and there is no way for the server storing this data to decrypt it.
Attackers have no means to compromise an instance, accidental data leaks cannot expose user data.
Self hosted and lightweight
You can run Offen on-premises, or in any other deployment scenario that fits your need.
All you need to do is download a single binary file or pull a Docker image, and run it on your server.
Offen will automatically install and renew SSL certificates for you if you want it to.
If you do not want to deploy a dedicated database, you can use SQLite to store data directly on the server.
Transparent and fair
Offen treats the user as a party of equal importance in the collection of usage data.
Users have access to the same set of tools for analyzing their own data and they can delete their data at any time.
Localize
Offen is currently available in English, German, French, Spanish and Portuguese. Our consent banner and the Auditorium for operators as well as users can be displayed in the respective locale.
