Flurry Analytics is a free mobile app analytics platform owned by Yahoo in the United States. It measures sessions, events and audiences and relies on mobile advertising identifiers such as Apple IDFA and Google GAID, plus Yahoo advertising cookies on the web. Because the data can feed advertising, it triggers consent obligations and raises notable transfer concerns for European publishers.
Flurry Analytics is a free mobile app analytics platform owned by Yahoo, a company based in the United States. It helps app publishers measure sessions, screen views, custom events, retention and audience segments across iOS and Android. Because it is offered at no cost, its business model is closely tied to advertising and audience monetisation across Yahoo properties. For European publishers this dual nature, analytics plus advertising, is the central compliance issue to understand before adoption.
On mobile, Flurry relies on device advertising identifiers such as the Apple IDFA and the Google advertising ID, alongside event and session data describing in app behaviour. On Yahoo web properties it can also read advertising cookies that contribute to profiling. The combination of a persistent identifier with detailed behavioural events allows individual devices to be tracked over time and linked to broader Yahoo audiences. This makes the processing far more intrusive than a simple visitor counter.
Advertising identifiers and advertising cookies are personal data and are subject to article 5(3) of the ePrivacy Directive, which requires informed consent before storing or reading information on a user device. The GDPR then governs the subsequent processing, and the advertising purpose means legitimate interest is not a safe basis here. Publishers must provide clear information about Yahoo as a recipient and about the advertising use. Failure to obtain valid consent before the SDK activates is a common and high risk compliance gap.

Valid consent must be freely given, specific, informed and unambiguous, and it must be collected before any identifier is read. In practice this means integrating Flurry behind a consent management platform and only initialising the SDK once the user has agreed. On Apple devices the App Tracking Transparency prompt must also be respected before the IDFA is used. Consent must be as easy to withdraw as to give, and withdrawal should stop the SDK and prevent further collection.
Flurry data flows to Yahoo infrastructure in the United States, so a valid transfer mechanism is required. Yahoo relies on the EU US Data Privacy Framework and on EU Standard Contractual Clauses as a fallback. Because the data can feed advertising, you should carry out a transfer impact assessment and consider supplementary measures rather than assuming the framework alone is sufficient. Document the recipients, the retention periods and the safeguards in your records of processing.
Block the Flurry SDK until consent is recorded, and wire it to your consent management platform so that opt out is honoured immediately. Complete a data protection impact assessment, given the ad funded model and the United States transfers, and keep it under review. Update your privacy notice to name Yahoo and to explain the advertising use, the identifiers and the transfers. Finally, consider whether a privacy first analytics tool would meet your measurement needs with far lower risk.
Websites using Flurry Analytics must obtain user consent under GDPR regulations.
DPIA considerations
A data protection impact assessment is strongly advised. Flurry is free and ad funded, combines mobile advertising identifiers with Yahoo audiences, and sends data to the United States, so it involves large scale behavioural processing and international transfers. Assess the lawfulness of consent, the transfer impact assessment for the EU US Data Privacy Framework and Standard Contractual Clauses, and the risk of further advertising use.
Sample consent text
We use Flurry Analytics, a Yahoo service, to understand how our app is used and to support advertising. This involves your device advertising identifier and may transfer data to the United States. Do you consent to Flurry Analytics?

Flurry Analytics collects user analytics data — you legally need a consent banner. Try FlowConsent free.
On mobile, Flurry primarily uses device advertising identifiers such as the Apple IDFA and the Google advertising ID rather than browser cookies. On Yahoo web properties it can also read advertising cookies such as A1, A3 and B. These identifiers persist over time and can link app activity to broader Yahoo advertising audiences.
Yes. Because Flurry reads advertising identifiers and cookies and may use the data for advertising, you must obtain prior consent under article 5(3) ePrivacy and article 6(1)(a) GDPR. The SDK should stay inactive until the user agrees, and on Apple devices the App Tracking Transparency prompt must also be honoured.
The appropriate legal basis is consent, both for storing or reading the identifiers under ePrivacy and for the subsequent processing under the GDPR. Legitimate interest is not suitable here because the data can feed advertising and profiling. Consent must be freely given, specific, informed and easy to withdraw.
Yes. Flurry is owned by Yahoo and processes data on infrastructure in the United States. Transfers rely on the EU US Data Privacy Framework and on EU Standard Contractual Clauses as a fallback. Given the advertising use, you should complete a transfer impact assessment and consider supplementary measures.
A data protection impact assessment is strongly advisable. Flurry is free and ad funded, combines persistent identifiers with behavioural events at scale, and transfers data internationally. These factors point to likely high risk processing that should be assessed and documented before launch.
Integrate the SDK behind a consent management platform so it only initialises after the user agrees, and respect App Tracking Transparency on iOS. Honour withdrawal immediately by stopping collection. Update your privacy notice to name Yahoo, describe the identifiers and advertising use, and document the United States transfers.
Publishers seeking lower risk often choose privacy first or self hosted analytics that avoid advertising identifiers and keep data in the European Union. Tools that offer aggregated, cookieless measurement can reduce or remove the need for consent. The right choice depends on whether you need advertising features or only product measurement.
List Flurry and Yahoo as recipients, describe the advertising identifiers and cookies, and state the consent legal basis and retention periods. Explain the United States transfers and the safeguards used. Keep the policy aligned with your consent banner so that the categories and vendors match.
