As shoppers gear up for the holiday season, Surfshark investigated the data collection practices of the 10 most popular shopping apps in the US, finding that US-based apps tend to collect more data compared to their counterparts in China and Canada. For example, Amazon collects 25 unique data types out of 35, but among Chinese apps, Alibaba is the most data-hungry, collecting 19 unique data types.
“Scrolling through tempting deals on Temu, Shein, Amazon, and other shopping apps is a Black Friday tradition for many. However, before downloading any shopping app, people should consider whether they are truly willing to trade their privacy for a discount,” says Miguel Fornes, Information Security Manager at Surfshark. “Many shopping apps collect far more data than people realize, and this extends beyond purchase history. Some apps can even gather sensitive information such as political views, racial background, or biometric and health data.”
The Amazon shopping app is the most privacy-intrusive. It collects 25 unique data types out of 35, Walmart and Costco each collect 23, and Whatnot — another US-based app — collects 20. Among Chinese apps, Alibaba is the most data-hungry, collecting 19 unique data types, followed by Temu with 17, Aliexpress with 16, and Shein with 15. The Canadian app, Shop, collects 19 data types, which places it on par with the most data-collecting Chinese app.
All the analyzed apps collect information such as email address, name, payment information, physical address, user ID, search history, and product interaction. The majority of these apps also gather device IDs (except for Temu), phone numbers (except for Shein), photos or videos (except for Shop), and location data (except for Shein). Additionally, most of this collected data is directly linked to individual users, enabling these apps to build comprehensive user profiles, which raises privacy concerns.
Some of the data collected by these shopping apps is surprising and even bizarre. For instance, Amazon and Walmart collect sensitive information — which could include political opinions, racial or ethnic background, biometric data, genetic information, sexual orientation, disability status, or pregnancy details. Whatnot and Alibaba collect users’ contacts, such as contact lists from a user’s phone or address book. In addition, Amazon, Walmart, Whatnot, and Alibaba collect users’ voice or sound recordings.
According to Fornes, these abusive data collection practices can be very dangerous if an app is breached and information about a person is leaked. First, leaked bank account information and purchase history can lead to unauthorized charges, identity theft, and significant financial loss. Second, leaked sensitive information – especially sensitive data like political views or health data – can damage your reputation and financial standing, as health data rarely changes and may be used by insurance and healthcare companies. Finally, all this leaked data might fuel subsequent highly personalized phishing campaigns. Therefore, Fornes advises:
- Don’t download apps you don’t need. If you only shop on Amazon occasionally, accessing their website through a browser is more private than keeping the app installed. Besides, you may improve your battery or device health by offloading those.
- Grant permissions selectively. Only allow access to data essential and directly relevant to the app’s functionality.
- Revoke unnecessary permissions. Regularly review and revoke permissions you have granted. For example, go to settings, apps, app name, permissions on iOS, and change them. Remember the app will still work as intended after removing unnecessary permissions, but just triggering some informational notifications.
- Read the Privacy Policy and opt out of data sharing. Understand what data the app collects, how it’s used, and with whom it’s shared. Many apps offer options to limit data collection for advertising purposes. Look for these settings.
- Strengthen your account security. Use strong, unique passwords; enable two-factor authentication (2FA); consider having a dedicated virtual debit card or escrow payment methods (such as PayPal) for such apps or shopping at less-trusted sites.

Guest Post – AI agents, Christmas markets, and sneaky greetings: holiday scams targeting you
Posted in Commentary with tags Surfshark on December 8, 2025 by itnerdAddictive scrolling, which develops faster than you think, is not the only thing you should watch out for this holiday season. A Surfshark expert highlights the main online risks you can encounter while scrolling.
Unsupervised AI shopping agents
AI shopping agents are a booming trend, with Big Tech announcing AI updates that can buy the exact sweater you are searching for and even call the shop to ask if they have it in stock. The trend of using chatbots like ChatGPT or Gemini AI to assist you with shopping is also at its peak.
Tomas Stamulis, Chief Security Officer at Surfshark, says the risk arises when you trust AI shopping assistants entirely and without double-checking. “I sometimes use a chatbot to help me with shopping. However, I evaluate what online shops it offers because sometimes they can be scams, taking me to malicious websites. So, always review what AI suggests before purchasing, and never grant unlimited access to your financial details.”
Phone snatching in Christmas markets
Phone snatching, when street criminals take your mobile phone from your hands, usually unlocked, is a particularly common crime in crowded Christmas markets. A moment of your distraction can result in far-reaching consequences. According to Surfshark expert Tomas Stamulis, taking simple steps can help protect you from the damage caused by phone snatching. “Stay vigilant in public, especially in crowded or high-risk areas. Keep your phone out of sight when not in use. Use an anti-spying screen so people around you can’t easily see what you’re doing. Also, ensure “Stolen Device Protection” is active on iOS or “Theft Protection” on Android (depends on device) and your home and work addresses are correct.”
Sneaky links in Christmas greetings
People’s interest in creating Christmas greetings online and sharing them with loved ones does not go unnoticed by scammers. You probably receive those snappy interactive greetings via social media, email, and SMS. Thank the sender for goodwill, yet never click the links included in those greetings. If you did and were led to a strange site, we hope you didn’t provide any of your private information, such as your real name, surname, email address, telephone number, or home address.
Sorry, it’s too good to be true
Have you ever encountered a Christmas deal that seemed too good to be true? It probably was. Scammers create fake gift deals for popular and hard-to-find items to trick shoppers into falling for them. Mr. Stamulis advises being skeptical of Christmas deals that seem unrealistically good. “Always verify the offer by checking the retailer’s official website. If you spot something that seems like a ‘hot deal’, look closely at URLs and other text for typos or unusual characters, which are red flags.”
Gifting your personal data via public Wi-Fi
Free Wi-Fi is available at cafes, restaurants, train stations, hotels, and other public spaces for your convenience. It’s just that the number one rule for a privacy-conscious person is never to use free public Wi-Fi. Public networks are frequently exploited by hackers, who can intercept sensitive data, including account credentials, email addresses, passwords, and financial information. “Without an active VPN, using public Wi-Fi is insecure; it’s like gifting your personal data to total strangers,” points out Tomas Stamulis.
Christmas cleaning your private data will thank you for
Most people want to tie up loose ends before the New Year. Paying back debts, making peace with those you’ve argued with, and just finishing unfinished business. Review the apps you’ve accumulated over the year and get rid of those that just take up space. Surfshark conducted at least a few studies that revealed mobile apps to be extremely data-hungry and privacy-intrusive. Your private data will thank you for this Christmas cleaning.
