If you only read the HacDC webpages (anything ending in hacdc.org), no more information is collected than is typically collected in server logs by web sites in general.
If you contribute to the HacDC Wiki or Blog, you are publishing every word you post publicly. If you write something, assume that it will be retained forever. This includes articles, blog posts, user pages and talk pages. Some limited exceptions are described below.
Photography and Security Cameras
No person shall be photographed at HacDC or at a HacDC event without their permission. Photographers shall explicitly state they intend to photograph before taking any pictures and gain the permission of those being photographed.
Cameras used for security purposes shall be avoided by HacDC whenever possible. No camera under HacDC control for security purposes shall store any image. Cameras may only be used for security purposes to allow physical access.
Publishing on the wiki and public data
Simply visiting the web site does not expose your identity publicly (but see private logging below).
When you edit any page in the wiki, you are publishing a document. This is a public act, and you are identified publicly with that edit as its author.
When you publish a page in the wiki, you may be logged in or not.
If you are logged in, you will be identified by your user name. This may be your real name if you so choose, or you may choose to publish under a pseudonym, whatever user name you selected when you created your account.
If you have not logged in, you will be identified by your network IP address. This is a series of four numbers which identifies the Internet address from which you are contacting the wiki. Depending on your connection, this number may be traceable only to a large Internet service provider, or specifically to your school, place of business, or home. It may be possible that the origin of this IP address could be used in conjunction with any interests you express implicitly or explicitly by editing articles to identify you even by private individuals.
It may be either difficult or easy for a motivated individual to connect your network IP address with your real-life identity. Therefore if you are very concerned about privacy, you may wish to log in and publish under a pseudonym.
When using a pseudonym, your IP address will not be available to the public except in cases of abuse, including vandalism of a wiki page by you or by another user with the same IP address. In all cases, your IP address will be stored on HacDC servers and can be seen by HacDC's server administrators. Your IP address, and its connection to any usernames that share it may be released under certain circumstances (see below).
If you use a company mail server from home or telecommute and use a DSL or cable Internet connection, it is likely to be very easy for your employer to identify your IP address and find all of your IP based HacDC project contributions. Using a user name is a better way of preserving your privacy in this situation. However, remember to log out or disconnect yourself after each session using a pseudonym on a shared computer, to avoid allowing others to use your identity.
The wiki will set a temporary session cookie (PHPSESSID) whenever you visit the site. If you do not intend to ever log in, you may deny this cookie, but you cannot log in without it. It will be deleted when you close your browser session.
More cookies may be set when you log in, to avoid typing in your user name (or optionally password) on your next visit. These last up to 30 days. You may clear these cookies after use if you are using a public machine and don't wish to expose your username to future users of the machine. (If so, clear the browser cache as well.)
User passwords are the only assurance of the integrity of a user's edit history. All users are encouraged to select strong passwords, never share them and to change them frequently. No one shall knowingly expose the password of another user to public release either directly or indirectly.
Every time you visit a web page, you send a lot of information to the web server. Most web servers routinely maintain access logs with a portion of this information, which can be used to get an overall picture of what pages are popular, what other sites link to this one, and what web browsers people are using. It is not the intention of HacDC to use this information to keep track of legitimate users.
These logs are used to produce site statistics; the raw log data is not made public, and is normally discarded after about two months.
Log data may be examined by developers in the course of solving technical problems and in tracking down badly-behaved web spiders that overwhelm the site. IP addresses of users, derived either from those logs or from records in the database are frequently used to correlate usernames and network addresses of edits in investigating abuse of the wiki, including the suspected use of malicious "sockpuppets" (duplicate accounts), vandalism, harassment of other users, or disruption of the wiki.
Policy on release of data derived from page logs
HacDC will generally only release log data:
- In response to a valid subpoena or other compulsory request from law enforcement
- With permission of the affected user
- Where the information pertains to page views generated by a spider or bot and its dissemination is necessary to illustrate or resolve technical issues.
- Where the user has been vandalising articles or persistently behaving in a disruptive way, data may be released to assist in the targeting of IP blocks, or to assist in the formulation of a complaint to relevant Internet Service Providers
- Where it is reasonably necessary to protect the rights, property or safety of HacDC, its users, members or the public.
HacDC policy should not permit public distribution of such information under any circumstances, except as described above.
Sharing information with third parties
See our Licensing Policy for how created content is handled by HacDC.
HacDC will not sell or share private information, such as email addresses, with third parties, unless you agree to release this information, or it is required by law to release the information.
Security of information
HacDC makes no guarantee against unauthorized access to any information you provide. This information may be available to anyone with access to the servers.
E-mail, mailing lists and IRC
You may provide your e-mail address in your Preferences and enable other logged-in users to send email to you through the wiki. Your address will not be revealed to them unless you respond, or possibly if the email bounces. The email address may be used by HacDC to communicate with users on a wider scale.
If you do not provide an email address, you will not be able to reset your password if you forget it. However, you may contact one of the Wikimedia server administrators to enter a new mail address in your preferences.
You can remove your email address from your preferences at any time to prevent it being used.
If you subscribe to one of HacDC's mailing lists, your address may be exposed to any other subscriber. The list archives of most of HacDC's lists are public, and your address may find itself quoted in messages. The list archives are also archived by Gmane and other services. Mails are usually not deleted or modified, but it may be done in extreme cases.
Information email addresses
Mail sent to HacDC is not publicly visible, but may be visible to a group of HacDC members. By sending a mail to a @hacdc.org address, your address may become public within the relevant group.
We have an IRC channel. By participating in this or any IRC channel, your IP address may be exposed to other participants.
HacDC reserves the right to keep logs of conversations within any IRC channels it designates. Different channels have different policies on whether logs may be published.
Data on users, such as the times at which they edited and the number of edits they have made are publicly available via "user contributions" lists, and in aggregated forms published by other users.
Removal of user accounts
Once created, user accounts will not be removed. It may be possible for a username to be changed (depending on the policies of your local wiki). HacDC does not guarantee that a name will be changed on request.
Whether specific user information is deleted is dependant on the deletion policies of the project that contains the information.
Deletion of content
Removing text from HacDC's wiki or blog does not permanently delete it. In normal articles, anyone can look at a previous version and see what was there. If an article is "deleted", any user with "administrator" access on the wiki, meaning almost anyone trusted not to abuse the deletion capability, can see what was deleted. Information can be permanently deleted by those people with access to the servers, but there is no guarantee this will happen except in response to legal action.
