Apple’s latest iOS 18.4 update includes a small but mighty addition you might not have noticed: a new setting that gives you more control over your location data.
It’s called “Improve Location Accuracy,” and it’s hidden deep in your iPhone’s settings, but it’s worth checking out.
Here’s what it does: when you turn this feature on, your iPhone will anonymously and securely send Apple the geo-tagged locations of nearby Wi-Fi hotspots and cell towers.
This data helps improve the overall accuracy of location services, making your GPS even more precise when you need it.
It’s all anonymous and encrypted, so there’s no reason to worry about privacy. Apple’s commitment to user security remains as strong as ever.
You don’t have to contribute to this crowd-sourced database if you don’t want to. If you’re someone who values total control over your data, you can toggle off the “Improve Location Accuracy” setting at any time.
This new option essentially allows you to decide how much you want to participate in Apple’s location service enhancements.

It’s not a flashy new feature but a perfect example of Apple’s ongoing push for user privacy and control.
For those of us who like to fine-tune every little setting on our devices, this gives us another layer of personalization without compromising the performance we rely on every day.

To find this new setting, follow these steps:
- Head over to Settings
- Tap Privacy & Security
- Select Location Services, and select System Services at the bottom.
- Then, scroll down to the “Product Improvement” section. There, you’ll find the toggle for “Improve Location Accuracy.”
It’s a small update but a significant step in giving you more transparency and control.
Whether you want your location data to help make your device smarter or you prefer to keep it locked down, iOS 18.4 gives you the choice. That’s a win in our book.
