The GDPR Compliance Checklist for Mobile Apps

The obligations are the same but the implementation is separate. Apps rely on SDKs rather than browser scripts, use their own device identifiers, and need a consent framework the ad networks recognize. A compliant website tells you nothing about your app, and the two need building independently.

Every SDK installed, what data each one accesses, why it needs it, and whether it can actually respect a consent decision. That last point is the one that catches teams out. An SDK with no mechanism for handling consent cannot be made compliant through configuration, so it has to be replaced or removed.

Before any SDK fires, on first launch. If an analytics or advertising SDK initializes while the prompt is on screen, data has already been collected without permission. This is the app equivalent of scripts running behind a website banner, and it is just as common.

It has to be explicit, informed, documented and straightforward to withdraw. Bundling also invalidates it: users need to accept or decline each purpose separately rather than agreeing to everything at once. A single accept button covering analytics, advertising and personalization together does not meet the standard.

Not for anything beyond what genuinely requires the data. The app has to work without non-essential technologies, so gating core features behind consent turns a choice into a condition. Making opt-out harder than opt-in through extra steps or buried settings falls into the same category.

Collection stops immediately and forwarding stops with it. Ceasing to collect while continuing to send previously gathered data to partners is a frequent gap, because the two are handled by different parts of the stack. The withdrawal has to propagate through both.

Records showing what each user consented to, when, and under which version of your notice, retained so you can produce them on request. Documentation is the part teams postpone because nothing depends on it day to day, and the part that determines the outcome if a regulator does make contact.

Yes, through data quality and trust. Valid consent produces signals your ad partners can actually use, which improves match rates and measurement. Apps that handle privacy well also give users a reason to keep permissions granted, and a retained permission is worth more than one extracted through a confusing prompt.
