GDPR for Kivy App

I have an Android app (a calculator) written in kivy and converted to an SDK.

I use Google Admob (Kivmob) to provide banner ads, and I want to integrate Admob SDK's to comply with GDPR by having a privacy policy displayed in the app and obtaining consent with the user messaging platform.

I can provide the app SDK and any other related files. I don't have a finalised privacy policy document, so a placeholder can be used provided I can swap in the final policy later.

please let me know if you can do this and provide an estimate on price.
Contact me with questions if you need more technical details.
