Data collected by Bibliogram

Bibliogram logs all incoming request URLs and the time of the request to the console but does not log headers, IP addresses, or other information. These logs are not stored on disk.

Bibliogram has a database that stores the usernames and IDs of viewed users, and all data about viewed posts. This data is not linked with the user that requested it.

Data collected by nginx

This server uses NGINX as a reverse proxy to Bibliogram. NGINX is configured without any logging. To fix problems or stop attacks, it may be necessary to temporarily store access or error logs. If this is the case, data such as but not limited to a timestamp, your IP, your useragent and the URL you access is stored. The collected data is kept for as long as is necessary to resolve the problem but for a maximum of 24 hours.

Sending data

Data collected by Bibliogram is not public and is never sent to any external services.
