Hello LoyceV! First of all, we would like to thank you for your honest and detailed feedback about your experience with UniJoin! Many of your points will help us to improve the user experience for our clients!

All responses to your feedback are in green font under a quote of you.

When possible, I choose a .onion instead of clearnet. It turns out UniJoin.io has a Tor mirror, but it's not mentioned in the ANN.

➡️ We will add the Tor mirror to our ANN thread.

User Interface
The first thing I noticed was excessive animations, which I strongly dislike (and UniJoin seems to love them). It reminds me of thousands of ICO websites that use heavy animations to impress users before running off with their money.
I prefer a website on which I scroll down and see the content instantly, instead of a website where everything slides into place every time I click PgDn. Waiting for the animations to finish is time lost that I can't use reading the content.

➡️ As you have already mentioned, we are really a big fan of a beautiful & modern user interface, including animations and so on. As for the page loading time, we will work on some improvements to increase the site performance.

At 1. Operating Details, after Transfer Delay, there's a "?". I expected a popup or clickable info, but there's nothing. The slider works and it's quite obvious what it does. I'd say remove the "?".

➡️ You are right, this popup is not working at the moment. We will remove it for now or add an explanation of what transfer delay means. Bitcoin newbies who don't know how Bitcoin Mixers work may not fully understand what transfer delay means, and why it is important to choose a random transfer delay, as it improves the privacy of a Bitcoin transaction.

After I clicked Continue, I got a Captcha. That was unexpected and a weird place.

➡️ We placed the Captcha at this point to prevent bots from creating thousands of orders.

Quote from: the Terms

I confirm that the address generated in the next step is valid for 24 hours only. Cryptocurrency funds sent to this address after 24 hours will not be accepted.

What happens if fees rise and the transaction takes 4 days to confirm? That's currently not very likely, but it has happened many times in the past.

➡️ This is not a problem as long as BTC is transferred within 24 hours. Even if the transaction has 0 confirmations, but a payment is detected, the address will be saved until it has two confirmations.

Quote from: the Terms

I confirm that I need to download the letter of guarantee after transferring coins to the generated address of Unijoin.

There it is again: what's the point of a letter of guarantee after depositing, if I don't get it before sending funds?

➡️ We have checked this matter again, and we will amend it. Letter of Guarantee will be made available for download before the transaction must be made.

Quote from: the Terms

I confirm that I have read and agree to the Terms and Conditions.

That's 9 pages of "legal language"! It's not very customer friendly to demand users to read 9 pages before continuing.

From Terms and Conditions:

Quote

The service is provided on a non-custodial basis.
~
trustless CoinJoin

I'll get back to this later.

I'd say 1.3 is unnecessary and a waste of time to read:

Quote

It is Your responsibility to keep your wallet backups, your wallet files, and your passwords secure.

I mean: it's obvious that's how Bitcoin works.

I strongly dislike point 5:

Quote

Any feedback (or similar content/document, feature suggestion) you submit is non-confidential and will become the sole property of the Service Provider. We will be entitled to the unrestricted use and dissemination of such feedback for any purpose, commercial or otherwise, without acknowledgment or compensation to You.

If I send a comment to any service, I don't expect nor appreciate it if they decide to use my email for advertising. This makes contacting the service a liability.

I'm no lawyer, but the way I read points 6 and 8 is that if UniJoin messes up and I lose my funds because of them, it's my risk and they're not liable. If that interpretation is correct, then obviously I don't like it.

➡️ We will completely revise the Terms & Conditions to make them more understandable for our users. In general, I can assure you that we fully value the privacy of our users and that only technically necessary information is stored until we no longer need it. So in terms of privacy, no one has to worry about their information. But we understand your point, so we will completely revise the T&C.

About the II. Privacy Policy: I didn't find the one thing I wanted to know: how long do you store information on my transactions, particularly linking my deposit and withdrawal addresses?

➡️ As mentioned one answer above, we only store information until it's no longer technically necessary.

Order Related Information - Is deleted right after a mixing order is completed. If nothing has been received, the information related to this order is deleted after the countdown of 24 hours has elapsed.
Support Tickets - Right after a ticket is closed, the whole chat will be completely deleted.
Affiliate Information - The commission of an order that came through an affiliate is calculated directly with the receipt of the BTC. After that, a commission is randomly generated for the affiliate and credited to the affiliate’s balance in his affiliate dashboard. After that, there is no connection between the referral and affiliate, because firstly, the commission is randomly generated, secondly, only absolute numbers is shown to the affiliate, so the affiliate cannot offset any amount. And thirdly, the affiliate is only shown the date the commissions is received, so he has no information about when the commission was credited.

I've reached 3. Send Coins:

Transfer between 0.001BTC and 250.000 BTC to the following address:

And this is where my main problem arises: UniJoin is asking to deposit anything between $50 and $12,000,000, but doesn't give me anything I can use to prove the deposit address even belongs to them! Earlier, in the Terms, I was promised a "non-custodial" and "trustless" transaction, but I don't even get a Letter of Guarantee. That means I have to trust UniJoin with anything from $50 to $12,000,000 and that doesn't make me feel very comfortable.

➡️ This is a very important question, so thank you for that! As mentioned earlier, we will now make the Letter of Guarantee available for download before a transaction needs to be performed. Experts can verify the validity of the Letter of Guarantee signature through RSA, with help of the Public Key and the signature format. It can be also checked automatically on the Restore Session page or Support page. The signature in the Letter of Guarantee is created by our server using a signature format & our private key. And the public key is displayed in the Letter of Guarantee. We will also add the public key in the footer of our website, so that our users can compare the public key in the Letter of Guarantee and on our website and verify that the Letter of Guarantee is authentic.

While we're on the subject of $12 million (and I'll remind you that I've never used CoinJoin before so I could be wrong): how are you going to CoinJoin such an amount, if there aren't several other users who deposit a similar amount around the same time?

➡️ We can guarantee that we have enough possibilities to mix such amounts via CoinJoin within 72 hours. We always recommend increasing the transfer delay for larger amounts. If the transfer delay is set too low, such large amounts may be mixed after the set transfer delay, but there will be an information for our users that the transaction is currently in a CoinJoin.

Tor settings used for testing
Security Level: Standard. I haven't tried Safer or Safest, which often breaks websites because it disables scripts.

➡️ You are right, setting the Security Level on Safest, will break the website and it won't be usable. Setting it on Safer will still make it usable.

We would like to thank you again for your detailed feedback! Many of your points have helped us to find improvements to our service and website. And it will also help many other users to read through this information to gain more clarity about the operations at UniJoin. If you have any other questions, or other feedback you would like to share with us, we would be glad to hear from you!
