In October, Kohler launched Dekoda, a camera that attaches to a toilet and uses AI to examine your poop. Some say you can’t put a price on good gut health, but the Dekoda costs $599 for the device, plus a subscription fee that ranges from $70 to $156 per year.

But after a blog post published this week raised questions about Kohler’s data practices for its new toilet gadget, the company was forced to explained what it means by «encrypted» data for customers, and what its policy is for training its algorithms on their… uh… waste information. And it’s not as straightforward as it initially appeared to be.

Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.

On its website, Kohler says Dekoda «analyzes gut health and hydration and detects the presence of blood in the toilet bowl, providing data for building healthy habits.»

On the same webpage, Kohler touts privacy features for the gadget. It says that the camera only ever points down into the toilet bowl, that it offers fingerprint authentication optionally via the Dekoda remote and that, «our technology is designed to keep your personal data personal. It is end-to-end encrypted.»

The blog post published by security researcher Simon Fondrie-Teitler raised questions about what that encryption entails and pointed out that Kohler would likely have access to the data and images collected by Dekoda. 

«Responses from the company make it clear that — contrary to common understanding of the term — Kohler is able to access data collected by the device and associated application,» he wrote.

Kohler responds to privacy concerns

Kohler itself appeared to confirm this notion in a statement it shared with CNET. It wrote: «The term end-to-end encryption is often used in the context of products that enable a user (sender) to communicate with another user (recipient), such as a messaging application. Kohler Health is not a messaging application. In this case, we used the term with respect to the encryption of data between our users (sender) and Kohler Health (recipient).»

The company went on to say: «We encrypt data end-to-end in transit, as it travels between users’ devices and our systems, where it is decrypted and processed to provide and improve our service. We also encrypt sensitive user data at rest, when it’s stored on a user’s mobile phone, toilet attachment and on our systems.»

In other words, the data Dekoda collects is encrypted in transit, but can be decrypted by the company on its end.

In regards to how the company uses the data for AI systems learning, Kohler said in the same statement: «If a user consents (which is optional), Kohler Health may de-identify the data and use the de-identified data to train the AI that drives our product. This consent check-box is displayed in the Kohler Health app, is optional and is not pre-checked.»

Based on Kohler’s statement, it will remove information that pairs a user’s identity with the data before it’s used for optional AI model training.

The meaning of ‘encrypted’

This may cause confusion for people who are familiar with the kind of end-to-end encryption offered by services such as Signal or even Apple. Here, the expectation that companies wouldn’t have access, or even a technological way, to decrypt data that people are transmitting through their services.

What Kohler is doing sounds different from that expectation, as Fondrie-Teitler points out in his post: «What Kohler is referring to as E2EE here is simply HTTPS encryption between the app and the server, something that has been basic security practice for two decades now, plus encryption at rest.»

Kohler did not respond directly to questions about Fondrie-Teitler’s post to CNET beyond the statement it shared.

The Nintendo Switch 2 is one of the most popular handheld gaming consoles and it continues to sell out rapidly after its launch this year. Bundles are a great way to get a game included at no extra cost and this one is a standout.

Right now, Walmart is selling the Nintendo Switch 2 + Mario Kart World bundle for $449 — a $50 discount from the regular $499 price. If you prefer Amazon, the retailer is price-matching. Note that you’ll only see the lower price once you add the bundle to your cart on both platforms. That’s a $50 savings on the standard cost, making it one of the better Switch 2 deals I’ve seen after Black Friday.

This bundle includes the Switch 2 console along with a full game download of Mario Kart World, the newest entry in Nintendo’s long-running and wildly popular kart racing series. With the Switch 2’s improvements, Mario Kart World takes advantage of higher resolution, smoother frame rates and more detailed tracks than we’ve seen in past games.

CNET’s Scott Stein reviewed the Switch 2 and gave it 8.5 out of 10, praising its design, display and notably better graphics than rivals like the Steam Deck. The Switch 2 is an excellent overall upgrade and earned an Editors’ Choice award from our team. It is worth noting, however, that, in his tests, the battery lasted a mere 2 hours before dying. He points out that storage will need upgrades as well, given that newer games are larger in size.

Why this deal matters

A $50 discount on a new console bundle is rare, especially this early in the Switch 2’s life cycle. Because Mario Kart World is a $70 title on its own, getting both the game and console for $449 is excellent value. If you’ve been waiting for a meaningful price break on the Switch 2, this is one of the best opportunities so far.

Back in the days before smartphones, it seemed like everyone had an MP3 player. The best-known device was the iPod, which debuted in 2001. It wasn’t the first portable media player, but it definitely helped popularize the idea of putting 1,000 songs in your pocket.

MP3 players continued to exist alongside smartphones for some time, and even added support for additional music file formats like WAV, AAC, WMA and FLAC. But as music streaming replaced the traditional practice of buying digital albums and tracks, it wasn’t long before having a separate music player felt redundant. iPod sales peaked in 2008 (the same year Apple launched the App Store for iPhones), and the last iPod was discontinued in 2022.

Still, just because you can keep all your music on your phone, that doesn’t mean it’s always the best idea. Let’s say you’re headed to the gym or going out for a run, and you don’t want to be tempted to check your messages. A separate portable music player gives you all your tunes without the distracting notifications.

Or say you’re somewhere with a poor signal: You’re riding the subway or driving through the woods, and you want to listen to a podcast. You can still access any episode that you’ve downloaded to your phone. But all those files take up precious storage space, which is probably already being used by your apps, photos and videos. 

One solution is a 2000s throwback: keep all your music and podcasts on a separate device. 

Before you rush out to buy a secondhand iPod or Zune, you might want to dig through that box in the back of your closet. Chances are, you already own a device that can be used as a dedicated MP3 player.

Your old smartphone is perfect for this task; it doesn’t have the classic iPod click wheel, but it can still run Spotify or hold the music files you own.

What are the requirements for turning an old phone into an MP3 player?

Your old phone probably no longer has a data plan. No problem: as long as it can still hold a charge and power up, you can play any track that you’ve saved in your digital music library. 

If you can connect your device to Wi-Fi, you can use it to stream songs or podcasts. And if you download your files while your device is connected to your home internet, then you can take them with you wherever you go.

To save your songs and podcasts, you’ll need to use the latest version of your preferred music streaming app. Even if your old phone can’t upgrade to the latest system software, there’s a decent chance that it can still run Spotify, YouTube Music or similar apps. 

Spotify can still be accessed on phones that were released eight years ago. You can download the app on any iPhone running iOS 16.1 (supported by devices as old as an iPhone 8 or iPhone X) or above. You have even more options if you use an Android phone: Spotify is supported on Android OS 7.0 (Nougat), which was released in 2016.

YouTube Music has similar requirements: you can download the app on iPhones running iOS 16 or above, and on Android phones running Android OS 8.0 or above.

SoundCloud can be downloaded on iPhones running iOS 16.4 or above, and on Android phones running Android OS 8.0 or above. 

Apple Music has the fewest restrictions. The app can be downloaded on iPhones running iOS 10.0 or above, and Android phones running Android OS 5.0 or above.

How to put your music on your old smartphone

If you’re using a streaming app like Spotify or SoundCloud, you can download tracks, playlists and albums to listen to them offline. However, you’ll need to have a premium subscription to the service. (Spotify lets free users download podcasts.)

As for how much music, audiobooks and podcasts you can download, your main limit will be the amount of storage on your device. 

Spotify lets you download up to 10,000 songs on up to five separate devices. You can keep your downloads indefinitely, as long as you maintain your Spotify Premium subscription and you access the app at least once every 30 days.

You can’t download individual songs separately on Spotify, but you can download albums or custom playlists. Tap the arrow icon to save the album or playlist to your library. Once they’re downloaded, they’ll be marked with a green arrow icon.

YouTube Music will let Premium users download an unlimited number of songs across up to 10 devices. To save a track for offline listening, tap the three-dots icon and tap Download. You’ll see a checkmark icon appear next to each saved track.

SoundCloud Go and Go Plus users can also download an unlimited number of tracks for offline listening. Tap the arrow icon next to any of your Liked songs and albums. 

Apple Music subscribers can download up to 100,000 songs. Go to your library, tap the three-dots icon next to the tracks you want to save offline, and tap Download. 

If you’ve purchased any songs or albums digitally, you can access those files from your phone’s music player app. And if you own CDs or other physical media, you might consider saving those tracks to your device with the help of an external disc drive. 

Once your old phone is set up with your favorite tunes, all you need to do is find a pair of wired headphones and party like it’s 2005.

Don’t have an old phone? Here are some great portable MP3 players

If you don’t have an old smartphone lying around or don’t feel like setting it up, you can still buy a brand-new MP3 player. These modern devices are compact and easy to use. They’re relatively affordable, with some options under $100. And they include a headphone jack — arguably one of the most important components of a dedicated music player.
