Zoom privacy risks: The video chat app could be sharing more information than you think

Zoom makes video chatting with colleagues easy, but you might be giving away more than you bargained for.

The Zoom video meeting and chat app skyrocketed in popularity as millions of people looked for new ways to work, study and socialize amid the coronavirus pandemic. With the option to customize your background and newer features such as Immersive View and a vanishing pen tool, it’s easy to see why Zoom’s popularity isn’t dwindling even as COVID-19 vaccines and booster shots roll out and offices become hybrid workplaces. But with all that popularity, comes privacy risks.

From built-in attention-tracking features (which have since been disabled) to exploitable software bugs and issues with «Zoom-bombing» (where uninvited attendees break into and disrupt meetings) — Zoom’s security practices have drawn scrutiny from users worldwide. New York’s Attorney General Letitia James sent Zoom a letter outlining privacy vulnerability concerns in March 2020. The Electronic Frontier Foundation also cautioned users working from home about the software’s onboard privacy features.

Privacy experts previously expressed concerns about Zoom in 2019, when the video-conferencing software experienced both a webcam hacking scandal, and a bug that allowed snooping users to potentially join video meetings they hadn’t been invited to, if those meetings were not protected with a password.

The issues exacerbated by widespread adoption at the start of the pandemic were just the latest chapter in the software’s rocky security history, and prompted Zoom CEO Eric Yuan to respond to concerns in April 2020, freezing feature updates to address security issues over a 90-day update rollout. Though Zoom has since added security features like end-to-end encryption, there are still a few things you should watch out for to keep your chats as private as possible.

Here are some of the privacy vulnerabilities in Zoom that you should watch out for.

Zoom’s cloud recording feature might share meeting video with people outside the call

For paid subscribers, Zoom’s cloud recording feature can either be a life-saver or a catastrophic faux pas waiting to happen. If the feature is enabled on the account, a host can record the meeting along with its text transcription and a text file of any active chats in that meeting, and save it to the cloud where it can later be accessed by other authorized users at your company, including people who may have never attended the meeting in question. Yikes.

As Mashable’s Jack Morse put it, «What that suggests, but doesn’t clarify, is that for non-webinar/standard meetings, your person-to-person chat messages would be later sent to your boss after a call recorded to the cloud.»

Zoom does allow a narrowing of the audience here, however. Administrators can limit the recording’s accessibility to only certain preapproved IP addresses, even if the recording has already been shared. Participants can also see when a meeting is being recorded.

Zoom even shared information with Facebook

By now, you’re used to hearing it from the privacy-minded: Don’t use Facebook to log in to other sites and software unless you want Facebook to have data on what you’re doing. Fair enough. But what to do when Zoom gets caught sending some of your analytics data to Facebook — whether or not you even have a Facebook account?

An analysis by Vice’s Motherboard found the iOS version of the Zoom app doing exactly that. Courtesy of Facebook’s Graph API, Zoom was telling Facebook whenever you opened the Zoom app, what phone or device you were using, and your phone carrier, location and a unique advertising identifier. Motherboard also reported that Zoom had updated its iOS app so the app would stop sending certain data to Facebook.

In a March 2020 blog post, Zoom addressed the issue, noting «our customers’ privacy is incredibly important to us, and therefore we decided to remove the Facebook SDK in our iOS client and have reconfigured the feature so that users will still be able to log in with Facebook via their browser.»

As late as March 2020, Zoom’s privacy policy contained some breezy language about its relationship to third-party data crunchers, which gives one reason to question where else — and to what extent — that data was being shared or sold that we didn’t know about.

«Zoom does use certain standard advertising tools which require Personal Data (think, for example, Google Ads and Google Analytics). We use these tools to help us improve your advertising experience (such as serving advertisements on our behalf across the Internet, serving personalized ads on our website, and providing analytics services),» the policy said at the time. «Sharing Personal Data with the third-party provider while using these tools may fall within the extremely broad definition of the ‘sale’ of Personal Data under certain state laws because those companies might use Personal Data for their own business purposes, as well as Zoom’s purposes.»

But at the end of March, Zoom updated its privacy policy. In a statement following the move, Zoom said that while it wasn’t changing any of its actual practices, it wanted to make its language clearer. Regarding its relationship to third-party data handlers described above, the company drew a line in the sand between its product and its website. «This only pertains to user activity on the zoom.us website. No data regarding user activity on the Zoom platform — including video, audio, and chat content — is ever provided to third parties for advertising purposes,» the company said.

You should probably review your Zoom and device security settings with an eye toward minimizing permissions, and make sure any anti-tracking software on your device is up to date and running.

It may not help, but it can’t hurt.

It’s also important to keep your Zoom app up to date so your privacy is always protected with the latest security patches. Luckily, Zoom recently rolled out a new automatic update feature that makes this process a whole lot more convenient.

How to Use the New Blood Pressure Tool on Your Samsung Galaxy Watch

You’ll need additional hardware to use the blood pressure monitoring tool on your Samsung Galaxy smartwatch.

After years of regional limits, Samsung is finally unlocking blood pressure monitoring for Galaxy Watch users in the U.S. Starting Tuesday, the feature is rolling out to the current Galaxy Watch 8 series as well as older models dating back to the Galaxy Watch 4. It’s a major addition for anyone tracking cardiovascular trends, but you shouldn’t expect a simple «plug and play» experience.

For starters, you’ll need to own (or buy) a traditional upper-arm blood pressure cuff to calibrate the feature on the smartwatch. And you’ll have to download a separate app, the Samsung Health Monitor app, on your smartphone. Then you’ll have to recalibrate with the cuff every 28 days to ensure accurate readings.

In other words, the blood pressure monitor requires a blood pressure monitor to function.

Samsung first introduced blood pressure monitoring on its watches in 2020, gradually rolling it out in other countries, but regulatory holdups kept it from being usable in the US.

Unlike Samsung’s ECG and sleep apnea detection features (both FDA-cleared), the blood pressure feature has not received FDA clearance and is intended for wellness purposes only. This means it is not a diagnostic tool and should not be used to identify or treat high blood pressure. Readings are also on-demand only, so you have to manually take them through the watch rather than having it happen automatically in the background.

That last part may change. Samsung’s announcement also noted that passive blood pressure trend monitoring is coming later this year.

Apple debuted FDA-cleared hypertension alerts on newer Apple Watch models in September 2025, which passively monitor and alert owners when it detects signs of high blood pressure. Oura and other wearable companies are working toward similar features through long-term data trends, though true on-demand blood pressure readings remain out of reach for most mainstream consumer smartwatches.

The blood pressure feature is compatible with Galaxy Watch 4 and will only work on watches paired with a Samsung Galaxy phone running Android 12 or higher. It will not be available on other Android phones or on Samsung’s Galaxy Fit tracker. And even if you check all those boxes, you might not get it right away. Samsung says it’s rolling out the feature in phases.

If you do have access (and a cuff handy), setup is fairly straightforward. Once your watch is connected to your phone, download the Samsung Health Monitor app, enable blood pressure tracking and follow the calibration steps while using your upper-arm cuff. Just know you’ll need that cuff nearby anytime you want to keep your readings accurate.

Google Upgrades Maps Features With More Gemini and Faster Photo Uploads

Google Maps strengthens its crowdsourcing efforts for its 500 million contributors.

Google announced three new features for Maps on Tuesday that should streamline sharing your experiences. Despite being a strong maps application itself, Google relies on everyday users to contribute their reviews, photos and videos so others doing research can make more informed decisions about places they plan to visit. With the new updates to Google Maps, you can access your photos faster to contribute to information about places you’ve been. You can also choose to have Google’s AI model, Gemini, caption your photos and more quickly check the contributions you’ve made in the past.

New photo and video recommendations

It’s not hard to share photos or videos for a location on Google Maps, but the app will now offer photo and video suggestions from your saved images — if you give it permission to do so. The new feature will appear on the Contribute tab at the bottom of the maps app. When scrolling through the view, you’ll see photo and video recommendations or the option to upload other photos.

How the specific photo and video recommendations are determined isn’t clear, but the new feature will likely use a photo’s geolocation if that setting is enabled in your camera’s settings.

A Google representative didn’t immediately respond to a request for comment.

This feature is now available globally on Android and will expand to iOS in the coming months.

Gemini will auto-caption your photos

Google’s giving your photos some Gemini power by automatically analyzing and captioning them once you’ve selected them to share. This could be helpful in situations where you have selected several photos you don’t care to caption.

If you don’t like what Gemini comes up with, you can edit or remove the caption completely before publishing your photos to Maps.

Gemini captions are available in English on iOS and will expand to other languages globally and Android in the future.

New ways to view your contributions

You can now show off your prior contributions to Google’s Local Guide community program.

When you contribute, you gain points, and the more you contribute, the more you can level up as a Local Guide. All your points and badges are now prominently displayed on your profile. Google’s also adding gold profiles for high-level contributors, so you know you’re reading reviews from experienced users.

The new contributor updates are rolling out now on Android, iOS and desktop.

This New Health-Tracking Pet Collar Is Like a Smartwatch for Dogs and Cats

Tractive announces two new smart collars armed with GPS tracking, AI-powered health monitoring and other tech tools.

Our pets can’t speak up and tell us how they’re feeling, or why and where they are hiding. Tractive, an Austria- and Seattle-based tech company that creates GPS tracking devices for pets, announced on Wednesday two new smart collars that, according to the press release, «will redefine pet care for millions of families.»

Is your pet stressed, breathing unusually or scratching too much? Much like the basic health-tracking features you can find on a smartwatch, the collars — the Cat 6 Mini ($79) and Dog 6 XL ($89) — are designed to track this behavior and communicate the issues to help maintain your dog or cat’s quality of life.

«Pets can’t tell us when something is wrong, but their bodies can,» Michael Hurnaus, CEO and founder of Tractive, said in a statement. «With cutting-edge sensors on every tracker, learnings from millions of pets and AI-powered insights, we’re turning one of the world’s largest pet data platforms into clear, simple information so pet parents can act sooner and care even better.»

When it comes to tracking collars, dogs have usually been the target pet audience for such devices. Tractive’s new Cat 6 Mini collar aims to provide the same service for your feline friend. You can use it to monitor your cat’s respiratory rate and resting heart rate and identify any health concerns early. It’s expected to ship on May 31.

The Dog 6 XL collar, an upgrade from the company’s previous dog wearable, is designed for dogs weighing over 55 pounds. It’s more durable for outdoor use and offers up to four weeks of battery life between charges. It comes equipped with a scratch-monitoring system that flags unusual scratching behavior caused by allergies, skin irritants and other stressors.

You can also use the app to access your pet’s travels and mark safe zones regarding walks, entries and exits. An AI-powered health hub displays your pet’s overall health stats and also acts as a GPS tracker in case your dog or cat goes missing.

How would a veterinarian interact with the data collected on the device?

A Tractive representative told CNET, «In our experience, veterinarians are most interested in baseline resting heart and respiratory rate, so it’s less about monitoring these vitals in real time during recovery from anesthesia/acute care and more about understanding if the baseline is changing day to day to identify the onset of new conditions or manage existing ones.»

Even though the collars use a SIM card and require a strong cellular connection to work properly, they can capture activity, sleep and health data while offline. However, without connectivity, the devices «ultimately will not provide any utility,» the representative confirmed.

You’ll need to download the accompanying app and select a separate subscription plan at an added cost. The one-year plan costs $120, the two-year plan costs $168, and the five-year plan costs $300.
