<td>Whether unmuted chats that are always included or pinned in a <ahref="/api/folders">folder</a>, will be kept in the Archive chat list when they get a new message. Ignored if <code>keep_archived_unmuted</code> is set.</td>
<td>If this flag is set, the <ahref="/constructor/inputPrivacyKeyStatusTimestamp">inputPrivacyKeyStatusTimestamp</a> key will also apply to the ability to use <ahref="/method/messages.getOutboxReadDate">messages.getOutboxReadDate</a> on messages sent to us. <br>Meaning, users that cannot see <em>our</em> exact last online date due to the current value of the <ahref="/constructor/inputPrivacyKeyStatusTimestamp">inputPrivacyKeyStatusTimestamp</a> key will receive a <code>403 USER_PRIVACY_RESTRICTED</code> error when invoking <ahref="/method/messages.getOutboxReadDate">messages.getOutboxReadDate</a> to fetch the exact read date of a message they sent to us. <br>The <ahref="/constructor/userFull">userFull</a>.<code>read_dates_private</code> flag will be set for users that have this flag enabled.</td>
<td>If set, only users that have a premium account, are in our contact list, or already have a private chat with us can write to us; a <code>403 PRIVACY_PREMIUM_REQUIRED</code> error will be emitted otherwise. <br>The <ahref="/constructor/userFull">userFull</a>.<code>contact_require_premium</code> flag will be set for users that have this flag enabled. <br>To check whether we can write to a user with this flag enabled, if we haven't yet cached all the required information (for example we don't have the <ahref="/constructor/userFull">userFull</a> or history of all users while displaying the chat list in the sharing UI) the <ahref="/method/users.getIsPremiumRequiredToContact">users.getIsPremiumRequiredToContact</a> method may be invoked, passing the list of users currently visible in the UI, returning a list of booleans that directly specify whether we can or cannot write to each user. <br><ahref="/api/premium">Premium</a> users only, non-Premium users will receive a <code>PREMIUM_ACCOUNT_REQUIRED</code> error when trying to enable this flag.</td>
<p>Telegram allows placing chats into folders, based on their type, mute status, or other custom criteria, thanks to folder blacklists and whitelists.</p>
<p>Whether people will be able to see our exact last online timestamp.</p>
<p>Note that if <em>we</em> decide to hide our exact last online timestamp to someone (i.e., users A, B, C, or all users) <strong>and</strong> we do not have a <ahref="/api/premium">Premium</a> subscription, we won't be able to see the exact last online timestamp of those users (A, B, C, or all users), even if those users <em>do</em> share it with us.</p>
<p>If those users <em>do</em> share their exact online status with us, but we can't see it due to the reason mentioned above, the <code>by_me</code> flag of <ahref="/constructor/userStatusRecently">userStatusRecently</a>, <ahref="/constructor/userStatusLastWeek">userStatusLastWeek</a>, <ahref="/constructor/userStatusLastMonth">userStatusLastMonth</a> will be set.</p>
<p>Get the exact read date of one of our messages, sent to a private chat with another user.</p>
<p>Can be only done for private outgoing messages not older than <ahref="/api/config#pm-read-date-expire-period">appConfig.pm_read_date_expire_period »</a>.</p>
<p>If the <code>peer</code>'s <ahref="/constructor/userFull">userFull</a>.<code>read_dates_private</code> flag is set, we will not be able to fetch the exact read date of messages we send to them, and a <code>USER_PRIVACY_RESTRICTED</code> RPC error will be emitted.<br>
The exact read date of messages might still be unavailable for other reasons, see <ahref="/constructor/globalPrivacySettings">here »</a> for more info.<br>
To set <ahref="/constructor/userFull">userFull</a>.<code>read_dates_private</code> for ourselves invoke <ahref="/method/account.setGlobalPrivacySettings">account.setGlobalPrivacySettings</a>, setting the <code>settings.hide_read_marks</code> flag.</p>
<p>When updating the <ahref="/api/peers">local peer database »</a>, all fields from the newly received constructor take priority over the old constructor cached locally (including by removing fields that aren't set in the new constructor).</p>
<p>Check whether we can write to the specified user (this method can only be called by non-<ahref="/api/premium">Premium</a> users), see <ahref="/api/privacy#require-premium-for-new-non-contact-users">here »</a> for more info on the full flow.</p>
<p>Telegram Premium is an optional subscription service that unlocks additional exclusive client-side and API-side features, while helping support the development of the app.</p></div>
