For optimal security, it is important to have a private user login to your Mac (that you do not share with others) if you are sharing a computer. Read <a href=\"https:\/\/support.apple.com\/kb\/PH25796?locale=en_US\" target=\"_blank\" rel=\"noreferrer noopener\">macOS<em>: Setting Up User Accounts<\/em><\/a> for more information on setting up individual accounts on your Mac.<\/p>\n\n\n\n<p>Day One currently offers <a href=\"https:\/\/dayoneapp.com\/guides\/settings\/how-to-set-up-end-to-end-encryption\/\">end-to-end encryption <\/a>for data synced with Day One Sync. If you would like to encrypt your data today, you can use Apple&#8217;s <a href=\"http:\/\/support.apple.com\/kb\/ht4790\" target=\"_blank\" rel=\"noreferrer noopener\">FileVault<\/a> service.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-day-one-ios\">Day One iOS<\/h2>\n\n\n\n<p>Like the Mac version, you can enable a Day One passcode to restrict usage to yourself or those with whom you share the passcode. Follow these steps:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Open Day One.<\/li>\n\n\n\n<li>Tap Settings, then tap the Passcode\/Touch ID.<\/li>\n\n\n\n<li>Enter and verify your passcode.<\/li>\n\n\n\n<li>By default, your passcode will be required whenever you leave Day One or your device goes to sleep. Tap &#8220;Immediately&#8221; to choose other frequency options for your passcode.<\/li>\n<\/ol>\n\n\n\n<p>To encrypt your data on your iOS device, you can enable a passcode <em>for your device<\/em> (this is different from the preceding Day One passcode). To do this, follow these steps:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Go to Settings.<\/li>\n\n\n\n<li>Tap &#8220;Touch ID &amp; Passcode&#8221;.<\/li>\n\n\n\n<li>Tap &#8220;Turn Passcode On&#8221;.<\/li>\n<\/ol>\n\n\n\n<p>For more information, read Apple&#8217;s support article, <em><a href=\"https:\/\/support.apple.com\/guide\/security\/data-protection-overview-secf6276da8a\/web\" target=\"_blank\" rel=\"noreferrer noopener\">Understanding Data Protection<\/a><\/em>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-day-one-android\">Day One Android<\/h2>\n\n\n\n<p>Day One Android has the option to enable a passcode or use a fingerprint sensor to unlock the app. To set this up:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Tap <strong>Settings<\/strong> &gt; <strong>Passcode<\/strong><\/li>\n\n\n\n<li>Enable <strong>Passcode<\/strong><\/li>\n\n\n\n<li>Create a new 4-digit passcode<\/li>\n<\/ol>\n\n\n\n<p>If your device supports fingerprint authentication, you\u2019ll have the option to use it instead of typing your passcode.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-day-one-web-app-and-windows-app\">Day One Web App and Windows App<\/h2>\n\n\n\n<p>The Day One web app supports end-to-end encryption for all your journals and journal entries. However, to set up encryption for your account, you must first use the Day One mobile app or Mac app. Once encryption is set up on one of those platforms, it will also apply to your journals and journal entries in the web app.<\/p>\n\n\n\n<p>Like most web apps, the Day One web app stores your personal data and journal content in your browser. If you&#8217;re concerned about leaving data behind in the browser&#8217;s storage, we recommend using the Day One web app in <strong>Incognito<\/strong> or <strong>Private<\/strong> mode. Closing the tab will remove the data from your browser.<\/p>\n\n\n\n<p>If you&#8217;re using a shared or public computer, always use a private browsing session and <strong>log out<\/strong> after each session. This will remove all Day One web app data from the computer.<\/p>\n\n\n\n<p>Day One for Windows shares many of the core features of the Day One web app. If you&#8217;re using Day One for Windows on a shared or public computer, always log out after each session. This will remove all Day One data from the app.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-syncing\">Syncing<\/h2>\n\n\n\n<p>If you are using Day One Sync, see our privacy policy and FAQ for <a href=\"https:\/\/dayoneapp.com\/guides\/day-one-sync\/end-to-end-encryption-faq\/\">end-to-end encryption<\/a> for more information.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-active-devices\">Active Devices<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-can-i-check-which-devices-are-signed-into-my-day-one-account\">Can I check which devices are signed into my Day One account?<\/h3>\n\n\n\n<p>There is currently no way for you to check which devices have logged in to your Day One account, but you can <a href=\"https:\/\/dayoneapp.com\/guides\/contact-support\/\">contact support<\/a> if you have any security concerns, and we&#8217;ll be happy to advise.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>            Data
