Scan a mobile app for trackers

An app’s trackers are invisible on screen: they live in its traffic. Paste a Google Play link, Skanopy runs the app on a real phone and sends you the list of third parties it actually contacts. Free, within 48 hours.

What the analysis surfaces

An activity report, not a list of libraries. The free flash audit covers the first two readings; the full audit, all six.

  • The trackers actually active

    Every third party contacted while the app runs, including the ones firing in the background with nothing on screen to show for it.

  • The company behind each domain

    Every contacted host is attributed to its company and classified: advertising, audience measurement, attribution, social networks.

  • The timing against consent

    What leaves before the banner, while it waits for an answer, and after a refusal. Every reading is dated and placed in the journey.

  • The data that leaves

    The identifiers and device data transmitted, with the third party receiving them.

  • The destination

    The country of each contacted server, the host behind it, and that country’s data-protection level per the CNIL referential.

  • The gap with the banner

    The active parties the consent screen does not declare, from the IAB list or added outside it.

Why a list of SDKs is not enough

Most scanners list the SDKs they recognize inside the installer file. That is a photograph of the code, not of the activity: a kit can sit there silent, and data can leave without any known library giving it away.

95

third parties fired despite the tracking refusal, across 20 news apps.

What a CNIL inspection checks

Frequently asked questions

  • A component, most often a third-party SDK, that collects information about usage or the device and transmits it to its company: audience measurement, advertising, campaign attribution, personalization. Reading or writing information on the phone is the very act that, in France, Article 82 of the Data Protection Act governs.

  • Two approaches exist. Inspecting the installer file gives the list of embedded libraries. Running the app and observing its traffic gives the trackers actually active, when they fire and what they transmit. Skanopy practices the second, fully automated, on a real phone.

  • Yes. The flash audit analyzes your app and emails you, within 48 hours, the list of third parties it actually contacts. No commitment, no credit card.

  • Android apps: a Google Play link is enough, or an .apk file for an unpublished app. There is nothing to integrate into the app, and nothing for the publisher to prepare.

  • Compare the list with what your privacy policy, your record of processing and your consent banner declare. The gaps define the work: partners to document, consent to fix, SDKs to reconfigure. The full audit then provides every issue proven and prioritized, with the fix to make.

  • No. What the law regulates is the timing and the conditions: most trackers require prior consent, and must stay silent after a refusal. The issue is not their presence, it is their behavior.
