Concentration Risk Disclosure [Text Block] | (9) Business Risk and Credit Risk Concentration Involving Cash For the fiscal year ended June 30, 2022, the Company had two customers that substantially comprised all of the Company’s revenue. All of the Company’s revenue for the fiscal year ended June 30, 2021 was also generated by two customers. The Company maintains funds in bank accounts that may exceed the limit insured by the Federal Deposit Insurance Corporation (the “FDIC”). The risk of loss attributable to these uninsured balances is mitigated by depositing funds in what the Company believes to be high credit quality financial institutions. The Company has not experienced any losses in such accounts.
