== About this site ==
 * This site is a combined help and bug tracking system for JOSM and JOSM plugins.
 * No login is required to use this site (either to read or edit the Wiki or the bug tracker).
 * But logging in has advantages:
  * You will receive notifications of changes to your bug tracker tickets. This is also possible by entering an e-mail as a username in the tickets, but be aware that the address will be publicly visible and you will not be able to change it later.
  * Page settings will be remembered (e.g. input field size and a lot of other stuff).
 * Registrations without an e-mail address and unused registrations are automatically deleted.
 * Accounts for editing the OpenStreetMap database are separate from the accounts on this server.
 * The copyright (CC-BY-SA and LGPL since April 2014) of this site is stated in the footer.
 * Personal data, such as e-mail address, is used only for contact purposes related to the JOSM software. There is no user tracking or advertising.
 * Data about the usage of this website is stored for statistical purposes (including usage initiated by JOSM). Raw logs including IP addresses are deleted after a few weeks when no longer required.

 * JOSM wiki page uses a Let's Encrypt certificate which is constantly renewed ([/certs/josm.openstreetmap.de.crt]).
 * JOSM JAR release files are signed with a private certificate ([/certs/josm.openstreetmap.de_code.crt]) from a private CA ([/certs/stoecker2023.pem]). **You'll may have to accept a warning at least once.**
 * JOSM GitHub files and Windows version are signed with a private certificate ([/certs/josm.openstreetmap.de_code_github.crt]) from the same CA.  **You'll may have to accept a warning at least once.**
