Safe Doc Configuration

This article is written for Google Workspace for Education (GWFE) Admins. Note Safe Doc configuration is not supported for personal gmail accounts.

At out of the box without any policies setups except the license key, Safe Doc eliminates these kids-inappropriate features in GWFE,

the image searching feature (in Docs, Slides etc.)
the video searching feature (in Slides, Forms etc.)
the Explore feature (in Docs, Slides etc.)
the Dictionary feature (in Docs, Slides etc.)
the link preview feature (in Docs, Drawing etc.)
the middle finger emoji (in Docs, Gmail, Hangouts etc.)
games in google search, e.g. Snake, PacMan (in Google Search)
the Poop sticker in Hangouts (in Hangouts etc.)

But every chef has their own taste. With that in mind, Safe Doc supports policy configurations to customize which Google Workspace features to block. To get a better understanding how policy works, take a look at Google's article Chrome Policy Management.

Policy Configuration Format

This article focuses on the Chrome profile based policy configuration via Google Admin Console. This policy management approach supports all managed Chrome browsers on Chrome OS / Windows / Mac / Linux.

In a nutshell, the policy configuration is a human-readable JSON file. The JSON includes a group of policies. A sample policy for Safe Doc is like

{
  "SafeDocLicenseKey": {
    "Value": "12345678-9012-3456-7890-1234567890"
  },
  "EnableExplore": {
    "Value": true
  },
  "EnableDictionary": {
    "Value": false
  },
  "EnableVideoSearch": {
    "Value": true
  },
  "EnableImageSearch": {
    "Value": false
  },
  "BlockAddVideo": {
    "Value": false
  },
  "BlockEmojis": {
    "Value": ["🖕"]
  },
  "BlockDocLinkPreview": {
    "Value": true
  },
  "BlockDriveSharedLinks": {
    "Value": {
      "Blacklist": [
        "1TTdYiQ_TgOlpNr-zyT8OpFLbwPmz0-g9XymYql5l1ZA",
        "*@*",
        "/*/*"
      ],
      "BlacklistExceptions": [
        "114xLJiJZ8OwXJ41sYyKdycT8Hy0ccbIgPVPG-n_6tew",
        "*@school.us"
      ],
      "DelegateAdminEmail": "[email protected]"
    }
  },
  "BlockWebPublish": {
    "Value": true
  },
  "BlockGoogleSearchGames": {
    "Value": true
  }
}

Each policy comes with a format of "PolicyName": { "Value": <the value> }. The "Value" property is a must. Missing it would invalidate the entire configuration and the changes won't be delivered to your students' Chrome browsers.

The policy value depends on its data type.

If it's a Boolean, the value is either true or false.
If it's a String, the value is a text like "this is a text".
If it's a Number, type a number.
If it's an Array (or List), then the value is like ["a", "b", "c"].
If it's an Object (or Group), then enclose policy elements with a pair of braces { property1: true, property2: false }. An Object is like a folder in your computer containing more files.

The definition of each policy can be found in Safe Doc Policy List below. Most Safe Doc policies are of Boolean type.

Be ware of typos. A redundant comma or missing curly bracket will break the policy configuration.

Edit Policy Configuration

First of all, We recommend you test your policy configuration in an isolated Organizational Unit (OU) to find a sweet spot of your blocking strategy. When you're ready, you can copy and paste the policy configuration to the production student OU(s).

To edit the policy configuration for an OU, follow these steps.

Log into Admin Console.
Go to Devices > Chrome management > Apps & extensions.
Select the OU with Safe Doc installed.
Click the Safe Doc app.
In the Policy for extensions of right panel, edit your policy configuration JSON.
If everything is correct, click Save to take effect. Then the Safe Doc extension in your test student accounts under this selected OU will be automatically receive the changes and block features as you configured.

Best Practices on Configuring Safe Doc Policies

Only enable the policies you needed. If you don't need to block the features in Google Workspace for Education, it's recommended to explicitly turn off the policy. Enabling too many policies may impact your students' Google apps performance and experiences.
Watch out for the default values when the policies are unset. For example, the EnableImageSearch with default value of false, that means the image searching feature is blocked if this policy does not appear in your policy configuration.
Side note: we're designing the naming convention towards Block<GWFE-feature> with the default value of false to make configuration more consistent.

Blacklist

This is a subsidiary property of BlockDriveSharedLinks policy.

Description	The blacklist of Drive file sources. Safe Doc can block Drive shared files in 3 forms. 1) A specific Drive file ID. Safe Doc blocks specific Drive files if their file IDs are in this blacklist. 2) All shared Drive files from specific owners. Input an email or emails of file owners. Safe Doc detects the owner of file link and block it if the owner's email address falls into the blacklist. Support the * wildcard. 3) All shared Drive files from owners from specific organizational units (OU). Specify the Organizational Unit Path. The OU path is a different representation of OU separated by a forward-slash '/'. For example, /Students/Elementary School/Grade 1 equals to District Domain > Students > Elementary School > Grade 1. Safe Doc looks up the OU of file owner and blocks the file link if the OU is in the blacklist.
Data type	List of Strings
Default	`[]`
Examples	`"Blacklist": [ "1TTdYiJ_TgOlpNr-zYT8OpELbwPmz0-g1XymYql5l1ZA", "1b4xLJiWZ8OwXJ45kYyOdycT8Hs0cabIgPVKG-n_6tew" ]` Block 2 drive files by their file IDs `"Blacklist": ["@gmail.com"]` Block all shared files from @gmail.com accounts `"Blacklist": [ "[email protected]", "[email protected]" ]` Block all shared files from 2 specific owners `"Blacklist": ["@"]` Block all shared files from anyone, including users in your domain.

Description	This policy configures the BlockUnnicknamedMeeting policy to wait for a given amount of time before the policy BlockUnnicknamedMeeting decides to block or not block a meeting. It does not block any Google Workspace features per se. Why use this policy? Because the default 5 seconds wait time may not be enough to students' Chrome browsers to load a meeting (slow devices or network), so that the policy BlockUnnicknamedMeeting may make a wrong decision. If this is the case, experiment to extend the wait time up to 15 seconds. The unit of wait time is seconds. Do not put the unit into the value. If this policy is not configured, the wait time is by default 5 seconds.
Data type	Number
Valid data	[5, 15] The value should be between 5 and 15, both inclusive. Any other numbers out of this range are ignored.
Default	5
