Is Opal safe?

It leans heavily on third-party trackers.

Our take. Opal is built with more third-party tracking code than 79% of the apps we have scanned, including an analytics SDK from Germany.

What it collects about you

Opal links 5 categories of your data to you.

From the developer's own App Store privacy label. These are the kinds of data Opal ties to your identity, and it also declares it shares data to track you across other apps.

How it compares

Where it sits among apps.

Every one of these apps we have scanned, on the two measures above: third-party trackers it carries (across) and data it links to you on its own label (up). Toward the top right is more invasive.

Each dot is one app app. Opal sits to the right, carrying more third-party tracking than most.

Other signals

Two more flags.

Each is a fact read straight from the app. The same checks run on every app we scan. Only the ones that apply here are shown.

!

It declares cross-app tracking

Its own App Store label says it tracks you across other companies apps and websites using your advertising identifier.

!

It sends analytics to a company in Germany

Adjust is a Germany company. Its analytics SDK is built into the app.

The evidence

What it's built from.

All 19 SDKs in the app, grouped by what they are for. 9 are third-party trackers.

9 of the 19 are third-party trackers. One is a push-notification SDK that delivers notifications, rather than tracking you across apps. The rest are the app's own code and standard open-source building blocks.

How we know this

Counterspy downloads the app from the App Store and statically analyzes its compiled binary. Embedded SDKs are matched against a signature database and resolved to the company that operates each. We also read the developer's App Store privacy label, which lists the data the app says it collects and links to you. We do not run the app or intercept its traffic, so we report capabilities present in the code and the developer's own disclosures, not proven transmission. We assess privacy and data collection, not malware, security flaws, or developer intent. Reports are automated and never edited for payment. Scan v3.152, 2026-03-28.

  1. Third-party trackers are advertising, analytics and attribution SDKs detected by static signature matching. Presence shows a capability is compiled in, not that it ran or transmitted data.
  2. "Data the app links to you" is the count of data categories the developer declares as Data Linked To You in its App Store privacy label. Labels are self-reported and not verified by Apple.
  3. Comparison across the 2020 apps in our corpus. Trackers: median 4. Data linked to you: median 4.
