The calculator produces an estimate based on the inputs you provide, it is not a guaranteed figure. The actual revenue impact in your app depends on your specific ad network configuration, your real traffic share, your mediation setup, and the CPM (cost per mille) your networks actually pay. The result is designed to show the scale of potential revenue at risk, not to predict an exact number.

A consent management platform (CMP) is a tool that collects, stores, and communicates user consent choices to your ad networks and analytics tools. In mobile applications, it handles the GDPR consent flow for EEA and UK users, which ad networks require to serve personalized ads. A CMP sits between your users and your ad stack, making sure consent is collected correctly, stored legally, and passed automatically to every network you monetize with.

Without a CMP, your ad networks either serve contextual-only ads or no personalized ads at all to users whose consent hasn’t been collected. This means lower CPMs and reduced fill from those users. A CMP fixes this in two ways. First, it ensures every network in your mediation stack receives a valid consent signal, so personalized ads can serve again. Second, an optimized consent flow increases the share of users who actually say yes, and every percentage point of additional opt-in translates directly into higher CPMs across your entire ad stack.

Yes. Even a small share of EEA or UK users is enough to trigger compliance obligations across every ad network in your stack. Without a CMP passing consent signals, those networks serve contextual-only ads to those users, which means lower CPMs and reduced fill. Beyond Europe, the US has a growing number of state-level privacy laws — including California, Colorado, Virginia, and others. That requires publishers to provide opt-out mechanisms for data sharing. Operating without a CMP in these regions creates real legal exposure. The direction across all major markets is toward stricter consent requirements.

Usercentrics App CMP covers GDPR and ePrivacy (EEA and UK), Google Consent Mode v2, TCF v2.3. It also supports CCPA opt-out for US users. For a full breakdown of supported regulations and how each one applies to your app, visit the regulations section on our website.

For most publishers, implementation is completed within one day. Usercentrics App CMP is available as a native SDK for both iOS and Android, with a setup wizard that handles TCF v2.3 compliance, Google Consent Mode v2, and Additional Consent for non-TCF networks in a single configuration session.

Not if it is done well. A well-optimized consent flow is designed to fit naturally into the user experience, appearing at the right moment, with clear and straightforward messaging. When implemented correctly, it does not disrupt gameplay or damage retention, and it ensures your ad networks can serve personalized ads to users who consent. The quality of the implementation determines the outcome far more than the presence of the prompt itself.
