If the opportunity for the input of personal or business data (email addresses, name, addresses) is given, the input of these data takes place voluntarily. The use of all offered services are permitted - if and so far technically possible and reasonable - without specification of any personal data or under specification of anonymized data or an alias. The use of published postal addresses, telephone or fax numbers and email addresses for marketing purposes is strictly prohibited, offenders sending unwanted spam messages will be punished.
The public and collaborative nature of this project
This project is collaboratively developed by its members using the MediaWiki software. Anyone with Internet access (and not otherwise restricted from doing so) may edit the publicly editable pages (if available) of these sites with or without logging in as a registered user (preferably with logging on). By doing this, editors create a published document, and a public record of every word added, subtracted, or changed. This is a public act, and editors are identified publicly as the author of such changes. All contributions made to this project, and all publicly available information about those contributions, are irrevocably licensed and may be quoted and adapted by third parties with limitations.
User accounts and authorship
This project requires editors to register with it. Anyone can edit pages with a username, in which case they will be identified by network IP address and by their chosen user name. Users select a password, which is confidential and used to verify the integrity of their account. Except insofar as it may be required by law, no person should disclose, or knowingly expose, either user passwords and/or cookies generated to identify a user. Once created, user accounts will not be removed without explicit reason.
When a page is edited by a logged-in editor, the server confidentially stores related IP information for a limited period of time. This information is automatically deleted after a set period. No more information on users and other visitors reading pages is collected than is typically collected in server logs by web sites. Aside from the above raw log data collected for general purposes, page visits do not expose a visitor's identity publicly. Sampled raw log data may include the IP address of any user, but are not reproduced publicly.
The sites set a temporary session cookie on a visitor's computer whenever a page is visited. Readers who do not intend to log in or edit may deny this cookie; it will be deleted at the end of the browser's session. More cookies may be set when one logs in to maintain logged-in status. If one saves a user name or password in one's browser, that information will be saved for up to 30 days, and this information will be resent to the server on every visit to the same Project. Contributors using a public machine who do not wish to show their username to future users of the machine should clear these cookies after use.
Edits or other contributions to an article, user pages and talk pages are generally retained forever. Removing text from a project does not permanently delete it. Normally, in projects, anyone can look at a previous version of an article and see what was there. Even if an article is "deleted", a user entrusted with higher level of access may still see what was removed from public view.
User contributions are also aggregated and publicly available. User contributions are aggregated according to their registration and login status. Data on user contributions, such as the times at which users edited and the number of edits they have made, are publicly available via user contributions lists, and in aggregated forms published by other users.
