Summary of Significant Accounting Policies [Abstract]  
Basis of presentation

A. Basis of presentation

The accompanying consolidated financial statements are expressed in U.S. Dollars and have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).
Principles of consolidation

B. Principles of consolidation

The consolidated financial statements include the accounts of Longduoduo and its subsidiaries. All significant inter-company accounts and transactions have been eliminated. The consolidated financial statements include 100% of assets, liabilities, and net income or loss of these subsidiaries.

LDD Technology Limited was established on March 18, 2024 under the laws of British Virgin Islands. LDD is a holding company with no business operations of its own. On February 19, 2025, Longduoduo issued 10,020 shares of its common stock to the original shareholders of LDD and assumed all the original shareholders' capital contribution obligations to LDD, in exchange for 100% of the outstanding shares of LDD. This transaction is treated in the Company’s financial statements as a corporate restructuring (reorganization) of entities under common control, as LDD and Longduoduo have at all times been under the control of Mr. Zhang Liang. Therefore, this transaction is accounted for by the carry-over basis method (also referred to as the pooling-of-interests method or historical-cost method). The assets and liabilities transferred are recorded by the receiving entity at their historical carrying amounts in the consolidated financial statements of the controlling parent, not at fair value. No new goodwill is recognized, and no gain or loss is recorded. In accordance with ASC 805-50-45-5, the current capital structure has been retroactively presented in prior periods as if such structure existed at that time, and the entities under common control are presented on a combined basis for all periods. Since LDD and Longduoduo were under common control for all periods presented, the results of LDD are included in the Company’s financial statements for all periods presented.

Longduoduo’s subsidiaries as of December 31, 2025 are listed as follows:

Use of estimates

C. Use of estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. Management makes these estimates using the best information available at the time the estimates are made; however, actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the inventory valuation allowance and the treatment of the shares issued. These estimates are often based on complex judgments and assumptions that management believes to be reasonable but are inherently uncertain and unpredictable. Actual results could differ from these estimates.
Functional currency and foreign currency translation

D. Functional currency and foreign currency translation

An entity’s functional currency is the currency of the primary economic environment in which it operates, normally that is the currency of the environment in which the entity primarily generates and expends cash. Management’s judgment is essential to determine the functional currency by assessing various indicators, such as cash flows, sales price and market, expenses, financing and inter-company transactions and arrangements. The functional currency of the Company is the Chinese Renminbi (“RMB’), except the functional currency of Longduoduo HK and LDDJK is the Hong Kong Dollar and the functional currency of Longduoduo and LDD is the United States Dollar (“US Dollars” or “$”). The reporting currency of these consolidated financial statements is in US Dollars.

The financial statements of Longduoduo’s subsidiaries, which are prepared using the RMB and HKD, are translated into the Company’s reporting currency, the US Dollar. Assets and liabilities are translated using the exchange rate at each reporting period end date. Revenue and expenses are translated using weighted average rates prevailing during each reporting period, and stockholders’ equity (deficit) is translated at historical exchange rates. Adjustments resulting from the translation are recorded as a separate component of accumulated other comprehensive income or expense.

Transactions denominated in currencies other than the functional currency are translated into the functional currency at the exchange rates prevailing at the dates of the transactions. Foreign currency exchange gains and losses resulting from these transactions are included in operations.

The exchange rates used for foreign currency translation are as follows:

      For the Six Months Ended
December 31,		 
      2025   2024 
      (USD to RMB/USD to HKD)   (USD to RMB/USD to HKD) 
Assets and liabilities  period end exchange rate   6.9956/7.7833    7.2985/7.7658 
Revenue and expenses  period weighted average   7.1238/7.7992    7.1772/7.7868 
Concentration of credit risk

E. Concentration of credit risk

The Company maintains cash in state-owned banks in China. In China, the insurance coverage per account of each bank is RMB500,000 (approximately USD$71,000). As of December 31, 2025 and June 30, 2025, the Company had $967,851 and $1,130,547 cash in excess of the insured amount, respectively.

For each of the six months ended December 31, 2025 and 2024, one customer accounted for 99.0% and 96.5% of revenue.

For the six months ended December 31, 2025 and 2024, the Company had one and three major suppliers that each accounted for over 10% of its total cost of revenue.

Cash and cash equivalents

F. Cash and cash equivalents

Cash consists of cash on hand and bank deposits, which are unrestricted as to withdrawal and use. All highly liquid investments with original stated maturity of three months or less are classified as cash and cash equivalents. Cash equivalents approximate or equal fair value due to their short-term nature. The Company’s cash and cash equivalents consist of cash on hand and cash in bank as of December 31, 2025 and June 30, 2025.
Property and equipment

G. Property and equipment

Property and equipment are stated at cost. Expenditures for maintenance and repairs are charged to operations when incurred, while additions and betterments are capitalized. Depreciation is recorded on a straight-line basis over the useful lives of the assets. When assets are retired or disposed, the asset’s original cost and related accumulated depreciation are eliminated from those accounts and any gain or loss is reflected in income.

The Company capitalizes certain costs associated with the acquisition of software. Once the software is ready for its intended use, these costs are amortized on a straight-line basis over the software’s expected useful life.

The estimated useful lives for property and equipment categories are as follows:

Office equipment and furniture     3 years  
Leasehold Improvements     1-5 years  
Intangible Assets

H. Intangible Assets

Intangible assets consist of software. Intangible assets are initially recognized at their respective acquisition costs. All of the Company’s intangible assets have been determined to have finite useful lives and are, therefore, amortized using the straight-line method over their estimated useful lives:

Software     3 years  
Fair value measurements

I. Fair value measurements

The Company applies the provisions of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Section 820, Fair Value Measurements (“ASC 820”), for fair value measurements of financial assets and financial liabilities and for fair value measurements of nonfinancial items that are recognized or disclosed at fair value in the financial statements. ASC 820 also establishes a framework for measuring fair value and expands disclosures about fair value measurements.

Fair value is defined as the price that would be received when selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining the fair value for the assets and liabilities required or permitted to be recorded, the Company considers the principal or most advantageous market in which it would transact, and it considers assumptions that market participants would use when pricing the asset or liability.

ASC 820 establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 establishes three levels of inputs that may be used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2: Quoted prices, other than those in Level 1, in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability,

Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity).

There were no transfers between level 1, level 2 or level 3 measurements for six months ended December 31, 2025 and 2024.

Financial assets and liabilities of the Company are primarily comprised of cash and cash equivalents, other receivables, due from related parties, accounts payable, due to related parties and other payables. As of December 31, 2025 and June 30, 2025, the carrying values of these financial instruments approximated their fair values due to the short-term maturity of these instruments.
Segment information and geographic data

J. Segment information and geographic data

The Company is operating in one segment in accordance with the accounting guidance in FASB ASC Topic 280, Segment Reporting. The Company’s revenues are from customers in the People’s Republic of China (“PRC”). Substantially all assets of the Company are located in the PRC.
Revenue recognition

K. Revenue recognition

The Company adopted FASB ASC Section 606 — Revenue from Contracts with Customers. Under ASC 606, the Company recognizes revenue from the sales of products and services by applying the following steps: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to each performance obligation in the contract; and (5) recognize revenue when each performance obligation is satisfied.

The Company recognizes revenue when the amount of revenue can be reliably measured, it is probable that economic benefits will flow to the entity, and specific criteria have been met for each of the Company’s activities as described below.

Service Revenue

The Company sells healthcare service packages to customers, which represent the rights to services purchased by the Company. The delivery of a healthcare service package to a customer represents a separate performance obligation. The Company’s policy is to recognize service revenue at that time when delivery of the healthcare service package has been contracted for, ownership and risk of loss have been transferred to the customer, and the service has been provided. Accordingly, revenue is recognized at the point in time when the service is provided. Service revenue is recognized when the healthcare service package has been delivered to the customer and there are no remaining performance obligations.

Management regularly reviews the sales returns and allowances based on historical experience. Any subsequent sales returns and cancellations are recognized upon notification from the customers. The liability for sales returns and allowances relating to the sale of healthcare service packages amounted to $161 and $208 as of December 31, 2025 and June 30, 2025, respectively. Management’s provision for sales returns and allowances was 1.66% and 1.4%, respectively, of the total service revenue for the six months ended December 31, 2025 and 2024.

The Company typically collects fees before delivery of healthcare packages. Amounts received from a customer before the delivery of the healthcare package are recorded as deferred revenue on the Consolidated Balance Sheets.

Commission Revenue

Commencing in the three months ended June 30, 2023, the Company started offering in a sales agent capacity healthcare service and product packages of a third-party provider. The third party is responsible for fulfillment of the services to the customer and the Company has no performance commitment or liability to the customer. The Company receives deposits from the customers, which are recorded as deferred revenue on the Consolidated Balance Sheets. The Company then remits to the third-party provider the provider’s contracted amounts, and retains the remaining amounts as commission revenue. The commission revenue is recognized upon acceptance of the customer contract by the third-party provider and is presented on a net basis in the Statement of Operations and Comprehensive Income (Loss).

Cost of Revenues

Cost of service revenue consists primarily of the cost of healthcare service packages purchased from third party healthcare service providers to fulfill contracts with customers.

Cost of product revenue consists primarily of the cost of healthcare products purchased from suppliers. Cost of product revenue is recognized when the product has been delivered to the customer.
Income taxes

L. Income taxes

The Company follows FASB ASC Section 740, Income Taxes, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred income taxes are recognized for the tax consequences in future years of differences between the tax bases of assets and liabilities and their financial reporting amounts at each period end based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

ASC 740-10-30 requires income tax positions to meet a more-likely-than-not recognition threshold to be recognized in the financial statements. Under ASC 740-10-30, tax positions that previously failed to meet the more-likely-than-not threshold should be recognized in the first subsequent financial reporting period in which that threshold is met.

The application of tax laws and regulations is subject to legal and factual interpretation, judgment and uncertainty. Tax laws and regulations themselves are subject to change as a result of changes in fiscal policy, changes in legislation, the evolution of regulations and court rulings. Therefore, the actual liability may be materially different from our estimates, which could result in the need to record additional tax liabilities or potentially reverse previously recorded tax liabilities or the deferred tax asset valuation allowance.

As a result of the implementation of ASC 740-10, the Company made a comprehensive review of its portfolio of tax positions in accordance with recognition standards established by ASC 740-10. The Company recognized no material adjustments to liabilities or shareholder’s equity as a result of the implementation.
Earnings (loss) per share

M. Earnings (loss) per share

The Company computes earnings (loss) per share (“EPS”) in accordance with ASC 260, Earnings Per Share. ASC 260 requires companies with complex capital structures to present basic and diluted EPS. Basic EPS is measured as net income (loss) divided by the weighted average common shares outstanding during the period.

Diluted EPS is similar to basic EPS but presents the dilutive effect on a per share basis of contracts to issue common shares (e.g., convertible securities, options and warrants) as if they had been converted at the beginning of the periods presented, or issuance date, if later. The computation of diluted EPS includes the estimated impact of the exercise of contracts to purchase common stock using the treasury stock method and the potential shares of converted common stock associated with the convertible debt using the if-converted method. Potential common shares that have an anti-dilutive effect (i.e., those that increase earnings per share or decrease loss per share) are excluded from the calculation of diluted EPS. 
Recently adopted accounting pronouncements

N. Recently adopted accounting pronouncements

We do not believe that any recently issued but not yet effective accounting standards, if currently adopted, would have a material effect on the Company’s consolidated financial position, statements of operations and cash flows.
