A new report from Surfshark reveals top astrology apps on mobile are sharing your info with third party partners.

You may be putting your personal privacy and data at risk every time you check your daily horoscope. If you’re into astrology apps on mobile, you could be sharing your data unwittingly with a bunch of third parties. At least, that’s according to a Surfshark report, which also reveals the top ten most popular astrology apps in the United States do exactly that — share user’s data with partners.

Ultimately, all the analyzed astrology apps from the report collect some form of user data. Whether that’s your email address, purchase history, advertising data, device IDs or other personal identifiers, it depends and varies from app to app. The report reveals that exactly half of those astrology apps “track” user’s data, and that information can end up in the hands of hundreds of partners. Surfshark defines tracking as “linking user or device data collected from the app with third-party data for targeted advertising or advertising measurement purposes or sharing it with a data broker.”

But that’s just tracking or associating certain collected forms of data. That doesn’t include apps scooping up data altogether — again, all the analyzed apps do this. What’s worse, they’re also sharing that info far and wide.

If that seems alarming to you, it should.

What is this Surfshark astrology app report?

The Surfshark report is available to read online through the brand’s official site. If you don’t want to read my take on everything, head on over, or you can always fact check through there, as well.

The apps analyzed include: AstroClub, Luna, The Daily Horoscope, AstroTalk, Astra, Starcrossed, CHANI, Co-Star, TimePassages, Nebula, and more. I occasionally check a few of those myself, like The Daily Horoscope or Co-Star. It might be time to quit that.

Speaking of Co-Star, Surfshark has pegged it at the most popular app with over 151,000 monthly downloads in the US alone. And when it comes to tracking user’s data, Nebula leads the way. It tracks five data types, including email address, purchase histories, advertising data, and beyond. Comparatively, Luna tracks two data types: product interactions and advertising data. Meanwhile, AstroClub, AstroTalk, and The Daily Horoscope all track one data type, which is device ID, other usage data, and device ID, respectively.

It’s not surprising that Nebula is also the most data-hungry of the apps. It collects 12 different data types — which, I should remind you, collecting is different than “tracking.” It scoops up user contact info, location, and other personal identifiers.

But none of the apps are privacy-friendly, for that matter. Sharing your info, consent or not, is not kosher.

How was this information gathered for the report?

According to the team, they identified the top most popular astrology apps first, with the help of AppMagic. To discover them, they used a time period of 2025, with the tag “Horoscope,” and looked at the iPhone App Store. Then, they “analyzed the privacy details of these apps on the Apple App Store, […] examining whether the apps collect data for the purpose of “Third-Party Advertising”, whether they collect any data linked to the user, and checked information about the collected data types.”

What should we do with this information?

As always, the decision that needs to be made is up to you. There’s nothing wrong with using these apps or checking your astrology information every now and then. But if you’re frequently using them, you might want to reconsider your patterns. That allows them more time to track and collect personal data, which is eventually being sold to third-parties and potentially compromising your privacy that much more.

The good news is now we know and have some idea of how to proceed, even if that is stopping the use of these apps altogether. They are sharing your info, after all. It’s probably for the best, considering Moonly’s app data leak that affected over six million users last year. It’s unfortunate that so many companies across every sector are so negligent and careless with our data and information. But that’s defnitely not going to stop anytime soon. That explains why there’s a lot of skepticism and anxiety surrounding modern tech.
