Erase This Confidential Information from Your iPhone Without Delay
As we approach the end of 2024, we've saved the most intriguing data privacy and security warnings for last. There's a secret data vault that you might not even realize exists on your device and should never fall into the wrong hands. Yes, the digital world is filled with threats, and some users are advised to take "extreme measures" to protect their data. But even the most careless individuals can still slip up.
So, what is this goldmine of data that caused one iPhone user to warn others "I'd rather he went through my internet history," after her boyfriend stumbled upon it with a single tap? Surprisingly, it's not location tracking or hidden photos—it's the often-overlooked history in iPhone's calculator app.
"Didn't know this was a thing," commented one user under a popular TikTok video that has now amassed over 600,000 views and bears the caption "3+8??????". Other calculations that were concealed in this data vault, according to the video's comments, include "3+3" and "1x10—it was a challenging day," and "as a math major, having 100x2 in my calculator is just embarrassing."
Regardless of its accuracy, there's a significant takeaway here.

Our phones now store an astounding volume and variety of our personal data. In fact, it's hard to think of any kind of personal data that isn't stored on our devices—devices that are prone to theft, accidental pick-up, and constant attack from phishing, smishing, and other crafty schemes aimed at stealing our data for financial gain.
There was a more concerning iPhone privacy issue reported this week—a new Apple Intelligence feature that shares hashed and anonymized user photo details to match with landmarks. The blog post that sparked media attention warned that "this morning while browsing the settings of various apps on my iPhone, I discovered a new setting for Photos that was enabled by default: Enhanced Visual Search."
Apple explains that "Enhanced Visual Search in Photos allows you to search for photos using landmarks or points of interest. Your device privately matches places in your photos to a global index Apple maintains on our servers. We apply homomorphic encryption and differential privacy, and use an OHTTP relay that conceals IP address. This prevents Apple from learning about the contents of your photos."

While this might be complex—as the original blogger noted, "I don't fully understand the technical details in Apple's blog post. I have no way to independently judge the reliability of Apple's implementation of Enhanced Visual Search"—simply put, the photo itself is never shared but analyzed on-device to identify the point of interest, which is then encrypted and masked before being matched centrally and returned. If it functions as advertised, there is no privacy risk for users consistent with Apple's focus on privacy-based cloud computing. But for most users, this is a leap of faith.
"From my own perspective," the blogger commented, "computing privacy is straightforward: if something happens entirely on my computer, then it's private, whereas if my computer sends data to the manufacturer of the computer, then it's not private, or at least not entirely private. Therefore, the only way to ensure computing privacy is to never send data off the device."
Apple advises that "you can disable Enhanced Visual Search at any time on your iOS or iPadOS device by going to Settings > Apps > Photos. On Mac, open Photos and go to Settings > General." As for deleting your potentially even more sensitive calculator history, it's a breeze. Simply tap the menu hamburger on the top left of the calculator app and then choose 'clear - clear history.'
- Despite Apple's focus on data privacy and their implementation of homomorphic encryption and differential privacy, some users remain skeptical and prefer to keep their data entirely on their device to ensure full privacy.
- With the rise of phishing, smishing, and other malicious schemes, it's crucial for iPhone users to take extreme measures to protect sensitive data, such as the history in the calculator app that can hold personal information.
- The recent report of a new Apple Intelligence feature sharing hashed and anonymized user photo details for visual search has sparked concerns about iPhone privacy, leading some users to disable the feature out of caution.
- An iPhone user caught their partner snooping through their calculator app's history, warning others about the unexpected and often overlooked goldmine of personal data in this seemingly innocuous app, highlighting the need to be aware of potential privacy breaches and take necessary security measures.
