I also got 1 year through buying my pixel. If you login with the same account through Gemini CLI, it should work (works for me)
However, Gemini CLI is a rather bad product. There is (was?) an issue that makes the CLI fall back to flash very soon in every session. This comment explains it well: https://news.ycombinator.com/item?id=45681063
I haven't used it in a while, except for really minor things, so I can't tell if this is resolved or not
