Indeed, it was this line that made me fall in love with wordleunlimited.dev: "This link opens your main site and loads the word game. Nothing is stored on a server." It is amazing how refreshing it is to find such a feature in the era when every little application collects your email, your contact list, and even your firstborn to give you an opportunity to send your personalized word to your wife. You write the word, the application creates a link and that's it.

How the Challenge Feature Works

You can see from the description above how it is incredibly simple you should just open the Unlimited tab, click on the Challenge a Friend button, type in your secret word (it should contain 4-7 letters), add your name (optional), set the timer (30 seconds, 1 minute or 2 minutes, depending on you), and click Create challenge link. That's it. Once your friend clicks on the created link, the word loads in his browser, and he starts guessing the word. No need to login on both sides. No need to "create an account in order to send a challenge". All you need is the link only.

What Does "Nothing is Stored on a Server" Mean

It seems to be the part that most people fail to understand. When it comes to other games with the challenges feature, once you create your custom puzzle, the server stores this data your IP address, puzzle ID, the word itself, and probably even your email if you created an account. All these data are stored somewhere in the database, and nobody knows what happens next. In contrast to that, in case of wordleunlimited.dev, your word and other settings are encoded into the link. It means:

• the word itself and the settings are not stored anywhere;
• your friend's gameplay is not monitored and not tracked in any way;
• there is no risk of leak because nothing is stored on the server;
• the link will work even years later since it doesn't depend on anything stored on the server.

Why It Really Matters

Okay, yes, it might seem to be an excessive concern about the privacy in the game for words, but it is the philosophy that really matters here. If even the browser game like that can implement challenges without storing any user data at all, there is no reason for larger applications to do that. The fact that wordleunlimited.dev went through the complex engineering way it encoded your word in the link instead of storing it on the server shows that developers took it into account instead of taking the standard approach of collecting the data that has become a default.

Several Practical Benefits of This Approach

• you can freely share your link through WhatsApp, Telegram, Discord, SMS, or even on a piece of paper since it works anyway;
• if you delete the chat where you shared the link, it is okay since your friend will be able to use it (provided it still works);
• your friend will never face the annoying "sign in to play" wall that stops almost all links from working;
• the link is portable you can start your puzzle on your phone and continue on your laptop;
• your puzzle will never disappear since there is no chance of the database wipeout.

Closing Words

Surely, it is a minor detail, but the minor details are the ones that show whether or not the product actually respects you. "Nothing is stored on a server" line under the challenge box at wordleunlimited.dev is the kind of detail that you will understand the importance of only once you were hurt by the opposite situation bloated applications asking for your data for something trivial. It is worth more for me than any "privacy first" brand that I have seen this year, and that is why it is my favorite challenge feature.
