Cloud torrenting services are an ideal tool to download content swiftly. They also help to hide your IP-address from the public at large. However, are they really anonymous? We asked the leading cloud torrenting services what their policies are.

Every day, millions of people download files through BitTorrent. This works well but there is one major drawback; everything you download can be tracked.
To bypass this privacy concern many people have started to use VPNs, many of which provide good anonymity. Others prefer cloud torrenting tools, which also help to hide users’ IP-addresses.
Over the past few years we’ve regularly asked VPN providers how anonymous they really are. However, little is known about the privacy policies and logging practices of cloud torrenting services. Today, we hope to fill this gap.
At the start of the week we reached out to several of the leading cloud torrenting services to ask some detailed questions. In particular, we wanted to know what information they store and if that can expose users.
The list of all questions, including the answers from providers, is listed below. At the bottom of the article we provide a summary, as well as a list of those who failed to respond at all.
1. Does your service collect any temporary or permanent data that can link a timestamp and IP-address to a specific user on your service? If so, what information do you collect and how long is that stored?
2. Does your service store any personally identifiable information of users (including IP-addresses)? If so, what information do you store, and for how long?
3. Does your service store the names/hashes or other identifying information of downloaded content (stored on your servers) that can be connected with a specific user? If so, for how long?
4. Does your service store the names/hashes or other identifying information of previously downloaded content (after being removed from the user’s account) that can be connected with a specific user? If so, for how long?
5. How does your service respond to DMCA notices or similar takedown requests?
6. Do you have a repeat infringer policy? If so, what does it entail?
1. No, we don’t log any IP access data. Our whole service is built to have minimal logging and is very light on the database level. That keeps things simple.
2. The most unique userkey is the user’s email address. We keep that for obvious reasons – to secure the account and reach the user. We keep it until the account is deleted. Apart from that we don’t store anything, but other information might be stored by our payment gateways. Nothing really can be done there except moving to Bitcoin – which we support and love.
3. There are two parts to our service. One is for fetching (eg a transfer job for importing the files into cloud storage) and then there’s the actual cloud storage. There is obviously a database that links the files to the user’s account but that connection is gone once the user deletes(removes) the file from their cloud. We cannot restore files and cannot backtrack who added/transferred what.
4.No, we do not.
5. Luckily we don’t have this problem since our business model does not contain any sort of sharing or publishing. Generated filelinks are locked to the user’s account and cannot be accessed externally.
6. We do not and it would be pretty hard since we do not have the logs. For now, we are content with the current legal situation.
TorrentFreak summary: There are no logs that can connect a person’s IP-address to an account. Premiumize can link files to user accounts and information
1. The last IP address is registered when the user logs on and it is cleared when the user logs out. This IP is only used to permit access to their downloaded files, and it is correlated with the login cookie. This is temporary and the privacy of the user is assured when they logout. The email is used to register and as an account recovery mechanism.
2. Each account is associated with an email address. Even though we frown on ‘temporary’ or ‘disposable’ emails, we make no effort in collecting the real name. In fact, if the user logs in with a Facebook account and refuses to share their email address, we don’t store any address at all. Email is only used to ensure the ownership of the account and allow users to ‘recover’ their own account and not be available for anyone else.
At any point, users can change their email address or delete it. Also, at any point any user can ask for account deletion and all information will be purged on request. We are working on adding an automatic mechanism for this.
Now, if the user upgrades their account, our payment processor asks for PII to ensure the identity of the user to protect against credit card fraud. This information STAYS on their servers and is not available from ours. We don’t use that information at all, we just receive the activation for a specific account.
3. See the next answer.
4. On all active or previous transfers the original request is stored as long as the user leaves them on their ‘downloaded’ list. As soon as they clear this list, that information is purged and can no longer be connected with the user.
5. We respond as soon as the request is received. We delete the referred content and comply, informing the user why it was deleted and suggesting they do not try downloading any copyrighted content.
6. We have not had to enforce any “repeat infringer” policies, but we do not disclose the limits we would consider as abuse to avoid users trying to “pass below the radar”. To be clear, although we do have a “fair use” policy for bandwidth usage, we have not had to impose any limits, as we try to permit the users to use the service to their maximum potential, and instead, we are really happy to see users enjoy it that much.
TorrentFreak summary: There are temporary logs that can connect a person’s IP-address to an account. TransferCloud can link non-deleted files and download histories to user accounts and information
1. Since we are a Turkish company we are required to abide by Turkish laws, which are more concerned about curtailing free speech than privacy. And since there is no speech at put.io we’re not keeping a list of [‘all’] used IP addresses.
We do keep the last used IP address to generate a download token that invalidates download links when requested from other IP addresses. We keep this last IP address as long as the user is logged in. It is erased when the user logs out or is inactive for 7 days. This is a precaution against abuse. We are currently working on a solution that will make it unnecessary to keep the last IP address.
2. We keep the username, reported email address and the last IP address for the purpose explained above. We have no access to users’ payment information. These are stored by our payment providers
3. There is an association with the account and the transfer jobs as long as they are displayed on the transfers page, and there is an association between the account and the files as long as they are stored under that account. There is also a history page that lists the latest transfer jobs, but it can be turned off.
These associations disappear the moment the transfers page is cleared, the files are deleted or the history page is cleared (or disabled). We wouldn’t be able to answer the question “What has this user downloaded?” after that.
Also, if the user ever destroys their account, we destroy everything related to the account. The only record we keep is a log entry that states that an account with that username was destroyed on that date. We had to add this to solve some mysteries with unintended account deletions.
4. No. If it’s not visible in the user interface we don’t keep it.
5. After 10 years in operation we have received only one DMCA request and that was meant for another service called Putlocker. The copyright holder had mixed up the services. We don’t receive DMCA requests, but if we ever did, we would comply and remove the content from our servers. That would be the end of it.
6. We have never had to develop a policy to deal with this.

Summary: How Anonymous Are Cloud Torrenting Services
Cloud torrenting services help people to hide their IP-addresses from the public. By doing so, they add an extra privacy layer. Outsiders can’t see what people download. However, true anonymity is a different matter.
The services can link stored files – and in some cases non-deleted download histories – to the personal information they store in their database. In that regard, they are similar to cloud hosting services. This is worth keeping in mind, as services can be compromised or legally required to share information.

From the outer reaches of space to the inner workings of regional language.
In some ways, podcasts are among the most quarantine-proof forms of entertainment right now. Maybe some bigger hosts have been forced to move their microphones and wall padding to a home office, or they're now hiding in closets for better sound quality (but not as an anxious reaction to terrifying and confusing news headlines).
But that doesn't mean all podcasts currently in production are a perfect fit for a nerd's listening diet, whether because they're too flippant or too doom-and-gloom. In my case, at least, I seek a mix of emotional support, comfort, and normalcy in my regular podcast library. Hence, I'm recommending the five podcasts below as my favorites if you're looking for that much-needed connection to the outside world. (These are in addition to other podcasts I've previously recommended at Ars.)
My latest selections tell uplifting stories; they feature friends talking about things they love; and while they've had to adapt to keep their hosts safe from COVID-19, they've held onto the joy and optimism that drew me to them in the first place. All of these podcasts have new, regularly updated episodes in common, and all of them revolve around research and science.
New study shows how to expand and manage a grid to limit fossil fuel use.
There's been a lot of discussion about how areas that are seeing explosive renewable growth can manage the large amount of intermittent electricity sources. But these mostly focus on regions with mature electric grids and a relatively static growth in demand. What would happen if you tried to grow renewables at the same time you're trying to grow a grid?
A EU-US team of researchers decided to find out what a good renewable policy might look like in West Africa, an area similar in size to the 48 contiguous US states but comprised of 16 different countries. Some of these nations already get a sizable chunk of their power from renewables in the form of hydropower, but they are expected to see demand roughly double in the next decade. Although renewables like solar and wind are likely to play a role purely based on their price, the researchers' analysis suggests that a smart, international grid can balance hydro, wind, and solar to produce a far greener grid.
Hydro as a giant battery
The new work has a mix of focuses. It's run against the backdrop of the expectation that West Africa's demand for electricity will explode over the next decade. Right now, the region has nearly 400 million inhabitants who consume a bit over 100 terawatt-hours a year (compared to the United States' 4,000TW-hr). By 2030, that demand is expected to be more than 200TW-hr—a fourfold increase from where demand was in 2015.

Legal comment launches as constellation companies scramble to satisfy astronomers’ concerns.
As much of the world has slowed down amid COVID-19, the same cannot be said for the burgeoning small satellite broadband industry. In recent weeks, SpaceX CEO Elon Musk announced he hopes to move the company’s Starlink broadband service to public beta in about six months. And that very same day, the Federal Communications Commission unanimously approved new rules for preventing orbital debris and collisions in space (those rules have been revised so as to not hamper NASA, but they still require more analysis, tracking, and disclosure from satellite companies). It's a small snapshot of what's been an ongoing debate: astronomy advocates say we are running out of time to preserve pristine views in the night sky, companies sending satellite constellations into space say they are mitigating the threat their satellites could pose to skywatchers.
The fleets of low-cost satellites will certainly be beneficial for telecommunications and Earth observation customers, particularly those living in remote areas. Crowds of satellites decrease the "revisit time" between satellite passes and make it easier to stay in touch, or to get frequent images during natural disasters.
Yet astronomers warn that without care, the satellites could ruin science observations and also make it difficult for groups like Native Americans who see the sky as part of their culture. Space organizations in Europe and the United States are already sounding alarm bells in reports and press releases. The European Southern Observatory (which operates the Very Large Telescope in Chile, among others) recently warned their observatories would be "moderately affected" if constellations launch at current rates. The National Science Foundation's Vera C. Rubin Observatory in northern Chile said nearly every image obtained during twilight "would be affected by at least one satellite trail."
