Privacy Policy

Last Updated: July 30, 2019

Our mission is to help you create, share and play knowledge games, including crosswords, sudoku, word search and quiz. We collectively refer to these as “Amuse Labs Proprietary Technologies”. We grew out of a privacy-focused research lab at Stanford University and value your privacy greatly. We want to make sure you understand what information we collect from our users and have tried to be as clear and transparent as possible in this document. However, please do not hesitate to contact our Data Privacy Officer at if you have any questions.


If you use Amuse Labs Proprietary Technologies as an iframe embedded at another site, we at Amuse Labs provide the games as a service to that site, and that site is your primary service provider. In that case, this privacy policy does not apply to you because that site is the data controller for all interactions with you, and we are a data processor, handling data on their behalf. If you have any information requests, please contact your service provider directly. The policy below applies only if you use our website directly.

If you are currently an Amuse Labs customer and have a contract in place with Amuse Labs, the data protection terms in that contract apply; this policy is not applicable.

Subject to the aforesaid statements, when you use any of Amuse Labs Proprietary Technologies, you acknowledge that you voluntarily agree to this Privacy Policy, including the manner in which we use your personal information.  If you do not agree to any of the terms in this policy, please do not use our services.

We have two  kinds of users on our website: puzzle solvers (or players) and puzzle creators. This policy applies to both kinds of users.

The data we collect

For puzzle solvers, we may retain the following information indefinitely (unless a delete request is specifically raised by you)

  1. The state of your unsolved and solved puzzles.
  2. Browser and device information
  3. Information about your usage patterns of any Amuse Labs Proprietary Technologies, including user interface elements on the puzzles such as reveal, check, social play, etc.

We retain the following for a limited time:

  1. The IP address from where you access our service, and the sequence of requests you make to our service.

For puzzle creators, in addition to all of the above, we collect your login identifier and data files for the puzzles (including questions, answers, metadata) you create or upload into our system. 

Aggregated Information 

“Aggregated Information” is a combination and/or analysis of information from multiple sources (as well as the information that you share) that helps identify or creates trends, benchmarks, summary metrics, or predictive algorithms. When creating aggregated information we take reasonable steps to prevent a specific individual or the individual’s data from being identified. We may create Aggregated Information from information that other customers choose to share with us, along with Your Information.

We may use Aggregated Information: 

  •       to deliver, develop and improve our products
  •       to enable general marketing and advertising statements about our products
  •       for other purposes to which you expressly consent

How we collect Information

For puzzle players: In order to identify your browser, we place secure cookies on your computer when you play a puzzle. The primary purpose of this cookie is to identify your browser when you revisit a puzzle, so that we can restore the state of a partially completed puzzle, to show you which puzzles you have attempted or completed, and to retain your settings preferences.  As you solve a puzzle, your browser may send us information about the partially completed state of the puzzle, which is associated with the browser’s cookie, so that we can restore it in case you revisit the puzzle again. If you do not want to allow the use of cookies, there is a simple procedure in most browsers that allows you to delete cookies, automatically decline them or be given the choice of declining or accepting cookies from a particular site. If you do not accept cookies, you can still play puzzles, but the above-mentioned benefits will not be available to you.

For puzzle creators: in addition to the above, we may place a cookie on your computer when you login, to avoid the need for you to login at every access. If you do not accept cookies, he above-mentioned benefit will not be available to you.

We may similarly use HTML5 local storage in your web browser to store the state of partially or fully completed puzzles, or your preference settings. Most web browsers allow you to directly disable HTML5 local storage, or view and delete information contained in it.

Our log files may retain for a limited time IP addresses of accesses, for the sole purpose of tracking any malicious attacks on our servers.  The exact duration of retention may be updated from time to time.

Your information may be stored by us directly, and also provided to a third party analytics provider like Google Analytics for the sole purpose of tracking aggregate analytics. However, we do not control or make any representations on behalf of such third Party.

We occasionally use third party email list software like MailChimp ( to contact constructors who voluntarily provide us contact information by logging in to our site. With each message, we always provide a way to unsubscribe from such a list. However, we do not control or make any representations on behalf of such third Party. 

All of the above technologies are in widespread use by mainstream websites.

“Do Not Track” Obligation

Do Not Track is a voluntary program among Internet advertisers that is intended to give users the ability to opt-out of behavioral targeting and advertising. There are a few ways in which your computer may send a “do not track” signal to certain websites and online services you visit.  Please send an email to if you want us to honor these signals from third party internet providers.

How We May Use and Share Your Information

We may use Your Information for the following purposes: 

  • To save the puzzle state, and restore it when you solve the puzzle from the same device or account
  • To deliver, administer, develop and improve our products

  • To debug to identify and repair errors in our products

  • To facilitate a judicial, regulatory or legal proceeding
  •  To protect our legal rights, such as pursuing available remedies or limiting the damages that we may sustain.
  • For other purposes to which you expressly consent

For these limited purposes Your Information may be accessed at the offices or servers of Amuse Labs (or third party service providers such as Google Analytics and Mail Chimp). These offices and servers may be located in the USA, India, or any other country or jurisdiction in which we or the third party service provider may have offices or authorized representatives. Therefore, your information may have to be transferred or processed in these jurisdictions, and may be subject to locally applicable laws. In using our services, you are consenting to such transfers of the information you share.
