11 Embed Privacy prevents the loading of embedded external content and allows your site visitors to opt-in.
12
13 == Description ==
14
15 Content embedded from external sites such as YouTube or Twitter is loaded immediately when visitors access your site. Embed Privacy addresses this issue and prevents the loading of these contents until the visitor decides to allow loading of external content.
16 But Embed Privacy not only protects your visitor's privacy but also makes your site load faster.
17
18 All embeds will be replaced by placeholders, ready for you to apply style as you wish. With only a couple of lines of CSS.
19
20 By clicking on the placeholder the respective content will then be loaded.
21
22 **Note: This plugins requires the PHP extension ["Document Object Model" (php-dom)](https://www.php.net/manual/en/book.dom.php).**
23
24 == Installation ==
25
26 1. Upload the plugin files to the `/wp-content/plugins/embed-privacy` directory, or install the plugin through the WordPress plugins screen directly.
27 1. Activate the plugin through the 'Plugins' screen in WordPress.
28 1. Embedded content will automatically be replaced by a placeholder and can be loaded on demand by your visitors. There are no additional settings.
29 1. To allow users to opt-out of embed providers that they set to always active, place the shortcode `[embed_privacy_opt_out]` into your privacy policy.

31
32 == Frequently Asked Questions ==
33
34 = Can Embed Privacy keep external services from tracking me/my visitors? =
35
36 Yes. As long as you don't opt in to load external content, you/your visitors can't be tracked by these services.
37
38 = Does Embed Privacy make embedding content privacy-friendly? =
39
40 The embedding process itself will be privacy-friendly with Embed Privacy. That means, that no third-party embed provider can track users without their explicit consent by clicking on the overlay to allow the embed to be loaded. However, to make sure everything is fine you need to expand your privacy policy for each embed provider you’re using or you want to use because you need to specify, where data will be sent to and what happens to them.
41
42 = Does Embed Privacy use cookies? =
43
44 If you use the opt-out functionality with the shortcode or the functionality to allow the user to always display content of certain embed providers, Embed Privacy creates a single cookie called `embed-privacy` with an expiration of 1 year to store the user’s choice.
45
46 = Does Embed Privacy support the block editor? =
47
48 Sure thing! We enjoy playing with the block editor and developed Embed Privacy with Gutenberg in mind, the plugin will work no matter the editor you use.
49

93
94 = Can Embed Privacy automatically download thumbnails of the embedded content? =
95
96 Yes! Since version 1.5.0, Embed Privacy supports downloading and displaying thumbnails in posts for SlideShare, Vimeo and YouTube as background of Embed Privacy’s overlay.
97
98 = Can users opt-out of already opted in embed providers? =
99
100 Yes! You can use the shortcode `[embed_privacy_opt_out]` to add a list of embed providers anywhere you want (recommendation: add it to your privacy policy) to allow your users to opt-out.
101
102 = What parameters can be used in the shortcode? =
103
104 The shortcode `[embed_privacy_opt_out]` can be used to let users opt-out of embed providers that have been set to be always active by the user. It can have the following attributes:
105
106 <code>headline</code> – Add a custom headline (default: Embed providers)
107
108 `
109 [embed_privacy_opt_out headline="My custom headline"]
110 `
111
112 <code>subline</code> – Add a custom subline (default: Enable or disable embed providers globally. By enabling a provider, its embedded content will be displayed directly on every page without asking you anymore.)
113
114 `
115 [embed_privacy_opt_out subline="My custom subline"]
116 `
117
118 <code>show_all</code> – Whether to show all available embed providers or just the ones the user opted in (default: false)
119
120 `
121 [embed_privacy_opt_out show_all="1"]

128 `
129
130 = Is this plugin compatible with my caching plugin? =
131
132 If you’re using a caching plugin, make sure you enable the "JavaScript detection for active providers" in **Settings > Embed Privacy > JavaScript detection**. Then, the plugin is fully compatible with your caching plugin.
133
