How to Write Best Message On GDPR Consent for Admob Apps

Here are some tips for writing a good GDPR consent message for apps using AdMob:

Clearly state what personal data is being collected. Be explicit about the types of data (name, email, location, device ID etc.).
Explain who the data is being shared with and for what purposes. Say it's being shared with Google/AdMob to personalize ads and measure ad performance.
Give options to consent or not consent to different types of data collection/processing separately. For example, consent to ads personalization vs analytics.
Make the language simple and easy to understand for a general audience. Avoid legal jargon.
Have clear "Accept" and "Decline" buttons/options. Decline should not hinder app use.
Let users know they can withdraw consent at any time by changing settings in the app or device settings.
Provide a link to your full privacy policy for more details.
Consider adding a line about how personal data is stored/processed securely in accordance with GDPR.
Test that the message is short, clear and visible on different device screen sizes.
Get user consent upfront, like on app launch, before collecting any personal data.
Thank users for their consent. Remind periodically as a courtesy for ongoing engagement.

The key is transparency around what data is used, who it's shared with, why, and options to consent or not while still using the app. Keep it concise but cover the core GDPR bases.

Here is a sample GDPR consent message for an app using AdMob where the developer does not directly collect any personal data:

"This app uses Google AdMob to display advertisements. To improve your ad experience and personalize ad content, Google may collect data about your device, apps, general location, and browsing activity.

Google is solely responsible for the personal data it collects, and your data will be handled in accordance with Google's Privacy Policy and Terms of Service. We do not have access to or control over the data collected.

By continuing, you consent to the collection and use of this data by Google for the purposes described. You can withdraw consent or adjust your settings at any time by changing your device's ad personalization and info settings.

If you have any questions about how Google uses your personal information, please refer to their Privacy Policy at www.google.com/policies/privacy."

The key points covered are:

AdMob is used for ads only, no developer data collection

Google alone handles any personal data collection

Purposes are described as ad personalization and info for Google
