DA Smart Solution

Independent mobile app developer — Viet Nam

About the “DA Smart Solution” application

DA Smart Solution is the name of the application that requests access to the Google Ads API on this project. It is an internal command-line tool, owned and used only by DA Smart Solution, whose sole purpose is to create, manage and report on the Google Ads App campaigns that promote our own mobile apps.

The application signs in with the Google account that owns our Google Ads accounts and uses the https://www.googleapis.com/auth/adwords scope. It has no public users, no end-user interface, and it does not process personal data. See our Privacy Policy for details.

Our Business Model

In-app advertising (Google AdMob)
In-app purchases and premium subscriptions

To grow our user base, we run Google Ads App campaigns that promote our own apps on Google Play, Google Search, YouTube, and the Google Display Network.

How We Use the Google Ads API

We use the Google Ads API to build an internal command-line tool that manages the Google Ads App campaigns promoting our own apps. The tool is used only by our own team. It is not sold, distributed, or made available to any external client or to the general public.

Capabilities

Campaign Creation — create App campaigns for our apps, including campaign budgets, target CPI bidding, and geographic and language targeting.
Campaign Management — update daily budgets and target CPI bids, pause and resume campaigns, and upload creative assets (headlines, descriptions, images, videos).
Reporting — retrieve performance metrics such as impressions, clicks, cost, installs, and in-app conversions, so we can monitor results and adjust our spend.

API services used

CampaignBudgetService, CampaignService, AdGroupService, AdGroupAdService, AssetService, CampaignCriterionService, GoogleAdsService.

Data handling

The tool reads and writes only our own Google Ads account data. It does not collect or process personal data of any end user, and no data is shared with third parties.
