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.) === Passwords === Many aspects of the lensowiki's community interactions depend on the reputation and respect that is built up through a history of valued contributions. User passwords are the only guarantee of the integrity of a user's edit history. All users are encouraged to select strong passwords and to never share them. No one shall knowingly expose the password of another user to public release either directly or indirectly. == Private logging == 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 the lensowiki to use this information to keep track of legitimate users. <!-- These logs are used to produce the [http://meta.wikimedia.org/wiki/Statistics site statistics pages]; the raw log data is not made public, and is normally discarded after about two weeks. -->Here's a sample of what's logged for one page view:  64.164.82.142 - - [21/Oct/2003:02:03:19 +0000] "GET /wiki/draft_privacy_policy HTTP/1.1" 200 18084 "http://en.wikipedia.org/wiki/Wikimedia_projects:Village_pump" "Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-us) AppleWebKit/85.7 (KHTML, like Gecko) Safari/85.5" 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 === It is the policy of the lensowiki that personally identifiable data collected in the server logs, or through records in the database via the CheckUser feature, may be released by the system administrators or users with CheckUser access, in the following situations: # 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 the lensowiki, its users or the public.<!-- this line borrowed from Google--> Lensowiki policy does not permit public distribution of such information under any circumstances, except as described above. == Sharing information with third parties == Except where otherwise specified, all text added to lensowiki projects is available for reuse under the terms of the GFDL. The lensowiki 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== The lensowiki 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 == 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 the lensowiki 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 lensowiki 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. == User data ==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 and on the number of edits you have). The Wikimedia Foundation 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 Wikimedia projects 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. [[Category:Policy|Privacy policy]]
