<div lang="en" dir="ltr" class="mw-content-ltr">
CheckUser is an interface for users with the ''checkuser'' permission. A user with the ''checkuser'' permission on a wiki can, in particular, check if a user is a [[w:sockpuppet (Internet)|sockpuppet]] of another user on that wiki (not on all wikis). By using it, users are able to:
</div>
* <span lang="en" dir="ltr" class="mw-content-ltr">Determine from which IP addresses an account has performed edits, logged actions, or password resets on the Wikimedia wiki;</span>
* <span lang="en" dir="ltr" class="mw-content-ltr">Determine all edits, logged actions, login attempts, and password resets that were performed on the Wikimedia wiki from a specific IP address (including users who were logged in with an account);</span>
* <span lang="en" dir="ltr" class="mw-content-ltr">Determine whether the account being checked has sent an email using the MediaWiki interface to any other user. The time of the event is logged; the destination email address and destination account is obscured.</span>
<div lang="en" dir="ltr" class="mw-content-ltr">
This information is only stored for a short period ([[phab:diffusion/ECHU/browse/master/CheckUser.php;5e62fbeb7ee86d5de5e8237978fa7180c0e422f4$30|currently 90 days]]), so edits made prior to that will not be shown via the CheckUser tool. A log is kept of who has made queries using the tool. This log is available to those with the ''checkuser-log'' permission:
</div>
<div lang="en" dir="ltr" style="{{quote style}}" class="plainlinks mw-content-ltr">
* {{#time:H:i, d F Y}}  [[user:Example|CheckUser]] got IP addresses for [[User:Example|Example]] ([[User talk:Example|talk]] | [[Special:Contributions/Example|contribs]] | [[Special:Block/Example|block]]) (a very good reason for looking at their IPs)
* {{#time:H:i, d F Y}}  [[user:Example|CheckUser]] got users for 127.0.0.1 (another good reason)
</div>
<div lang="en" dir="ltr" class="mw-content-ltr">
See [[Help:CheckUser]] for the user manual.

<div class="mw-translate-fuzzy">
==ഉപകരണത്തിന്റെ ഉപയോഗം==
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
The tool is to be used to fight vandalism, spamming, to check for sockpuppet abuse, and to limit disruption of the project. It must be used only to prevent damage to any of the Wikimedia projects.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
The tool should not be used for political control, to apply pressure on editors, or as a threat against another editor in a content dispute. There must be a valid reason to use the CheckUser tools to investigate a user. Note that alternative accounts are not forbidden, so long as they are not used in violation of the policies (examples of violations include double-voting, increasing the apparent support for any given position, or to evade blocks or bans).
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Notification to the account that is checked is permitted but is not mandatory. Similarly, notification of the check to the community is not mandatory, but may be done subject to the provisions of the privacy policy.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Some wikis allow an editor's IPs to be checked upon their request if, for example, there is a need to provide evidence of innocence against a sockpuppet allegation; note, however, that requesting a CheckUser in these circumstances is sometimes part of the attempt to disrupt.
</div>

<span id="Privacy_policy"></span>
== സ്വകാര്യതാനയം ==
{{main|1=Special:MyLanguage/Privacy policy{{!}}<span lang="en" dir="ltr" class="mw-content-ltr">Privacy policy</span>|2=Special:MyLanguage/Access to nonpublic personal data policy{{!}}<span lang="en" dir="ltr" class="mw-content-ltr">Access to nonpublic personal data policy</span>}}
<div lang="en" dir="ltr" class="mw-content-ltr">
On [[Special:MyLanguage/Wikimedia movement|Wikimedia]] projects, [[Special:MyLanguage/Privacy policy|privacy policy]] considerations are of tremendous importance. Unless someone is violating policy with their actions (''e.g.'' massive bot vandalism or spam) and revealing information about them is necessary to stop the disruption, it is a violation of the privacy policy to reveal their IP, whereabouts, or other information sufficient to identify them, unless they have already revealed this information themselves on the project.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Information release ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Even if the user is committing abuse, it's best not to reveal personal information if possible.
</div>

* <span lang="en" dir="ltr" class="mw-content-ltr">Generally, do not reveal IPs. Only give information such as same network/not same network or similar. If detailed information is provided, make sure the person you are giving it to is a trusted person and will not reveal it himself/herself.</span>
* <span lang="en" dir="ltr" class="mw-content-ltr">If the user has said they're from somewhere and the IP confirms it, it's not releasing private information to confirm it if needed.</span>
* <span lang="en" dir="ltr" class="mw-content-ltr">If you're in any doubt, give no detail.</span>

<div lang="en" dir="ltr" class="mw-content-ltr">
== Access to CheckUser ==
</div>
{{ambox|text=<span lang="en" dir="ltr" class="mw-content-ltr">Approved candidates for CheckUser permissions must sign, before being granted such permissions, a [[Special:MyLanguage/Confidentiality agreement for nonpublic information|confidentiality agreement for nonpublic information]] pursuant the [[Special:MyLanguage/Access to nonpublic personal data policy|access to nonpublic personal data policy]].</span>}}
<div lang="en" dir="ltr" class="mw-content-ltr">
Only [[Special:MyLanguage/Stewards|stewards]], [[Special:MyLanguage/Ombuds|ombuds]], some Wikimedia Foundation staff, and a very small number of other users are allowed to have CheckUser access. Users can only have CheckUser status locally (except for the ombuds and those staff members with access).
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
If local CheckUsers exist in a project, checks should generally be handled by those. In emergencies, or for multi-project CheckUser checks (as in the case of cross-wiki vandalism), stewards may perform local checks. Stewards should remove their own CheckUser access on the projects upon completion of the checks and notify the local CheckUsers or the CheckUser e-mail list.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
If no local CheckUsers exist for a project, requests will need to be made to the stewards to perform checks (such as "is UserX a sockpuppet of UserY"). To do so, simply add the request to [[Steward requests/Checkuser]] listing these users and explain the need for the check (with links). Depending on the nature of the request, the steward may deny it, may ask for more information, or may answer about the likelihood of the users in question having the same IP, same proxy, same network, same country, or being completely unrelated (''see discussion for what the steward should more precisely say to the editor'').
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Appointing local CheckUsers ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
On any wiki, there must be at least two users with CheckUser status, or none at all. This is so that they can mutually control and confirm their actions. In the case where only one CheckUser is left on a wiki (when the only other one retires, or is removed), the community must appoint a new CheckUser immediately (so that the number of CheckUsers is at least two).
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
On wikis with an Arbitration Committee (ArbCom) whose members have been elected with the support of at least 25–30 members of the local community, CheckUsers may be directly appointed by the Arbitrators. After agreement, a member of the Committee should simply list the candidate on [[Steward requests/Permissions]].
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
On a wiki without an Arbitration Committee that meets the criterion above, or in a project where there is a preference for independent elections, the community may approve local CheckUsers (stewards not counting as local CheckUsers) per consensus. The candidate must request the CheckUser status within the local community and advertise this request properly (village pump, mailing list when available, special request page, etc.). The candidate must be familiar with the [[Special:MyLanguage/Privacy policy|privacy policy]]. After gaining consensus (at least 70%–80% in pro/con voting or the highest number of votes in multiple choice elections) in the local community, and with at least 25–30 editors' approval, the successful candidate should request access at [[Steward requests/Permissions]] with a link to the page with the community's decision. If there are an insufficient number of votes for at least two CheckUsers on a wiki, there will be no CheckUsers on that wiki.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Mailing list ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
There is a closed mailing list ([[mail:checkuser-l|CheckUser-l]]) to which all stewards and CheckUsers should have access. Email the list moderators to gain access. Use this mailing list to ask for help, ideas and second opinions if you're not sure what the data means.
</div>

<span id="IRC_channel"></span>
===ഐ.ആർ.സി. ചാനൽ===

<div lang="en" dir="ltr" class="mw-content-ltr">
There is a private IRC channel ({{Channel|wikimedia-checkuser}}) to which all stewards and CheckUsers who use [[Special:MyLanguage/IRC|IRC]] should have access. This channel serves the same purpose as the [[#Mailing list|mailing list]], but in real-time. Contact any channel member to gain access; a channel manager will grant permanent access. Ask a steward if you need help gaining access.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Removal of access ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Any user account with CheckUser status that is inactive for more than one year will have their CheckUser access removed.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
In case of abusive use of the tool, the steward or the editor with the CheckUser privilege will immediately have their access removed. This will in particular happen if checks are done routinely on editors without a serious motive to do so (links and proofs of bad behavior should be provided).
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Suspicion of abuses of CheckUser should be discussed by each local wiki. On wikis with an approved ArbCom, the ArbCom can decide on the removal of access. On wikis without an approved ArbCom, the community can vote removal of access.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Complaints of infringement of CheckUser, Access to Nonpublic Information Policy or Privacy Policy breaches are handled by the [[Special:MyLanguage/Ombuds commission|Ombuds commission]] for all Wikimedia projects.
