Is key-rotation allowed during the active development phase of an app?

Hi team,

I am currently in the development phase of an application. I frequently hit the Free Tier rate limits (RPM) while running tests and building features.

I own a second personal Google account. Is it permitted to write a script that rotates between my two personal API keys to keep developing without interruption?

I want to ensure this isn’t considered “quota circumvention” or abuse.

Thanks for your help!
