SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
Dec. 31, 2021
Accounting Policies [Abstract]
asis of presentation	*Basis of presentation* The accompanying financial statements have been prepared in accordance with GAAP. The Company’s year-end is December 31.
Use of Estimates	*Use of Estimates* The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash and Cash Equivalents	*Cash and Cash Equivalents* The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents.
ncome Taxes	*Income Taxes* Income taxes are computed using the asset and liability method. Under the asset and liability method, deferred income tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities and are measured using the currently enacted tax rates and laws. A valuation allowance is provided for the amount of deferred tax assets that, based on available evidence, are not expected to be realized.
Revenue Recognition	*Revenue Recognition* The Company recognizes revenue in accordance with Accounting Standards Codification (“ASC”) 606, “Revenue from Contracts with Customers”. The core principle of ASC 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. An entity recognizes revenue in accordance with that core principle by applying the following steps: Step 1: Identify the contract(s) with a customer. Step 2: Identify the performance obligations in the contract. Step 3: Determine the transaction price. Step 4: Allocate the transaction price to the performance obligations in the contract. Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation. An entity must also disclose sufficient information to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers, including qualitative and quantitative information about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. 15 Crona Corp. NOTES TO THE FINANCIAL STATEMENTS December 31, 2021 and 2020 The contract between the Company and the customer is signed without specific quantity of service to be used from the date of signing. The revenue depends on the hours spent on the recording services. The rates of the specific services are set out in the contract. The Company’s revenues are recognized at a point-in-time as ownership of track, mix or master (when it is approved by the customer) is transferred at a distinct point in time per the terms of a contract. The Company shall not be liable for any failure to perform its obligations if such failure is due to circumstances beyond its reasonable control. Any liability of the Company shall be limited to the total of all amounts paid by the customer for services under the contract.
Basic Income (Loss) Per Share	*Basic Income (Loss) Per Share* The Company computes income (loss) per share in accordance with ASC 260. Basic loss per share is computed by dividing net income (loss) available to common shareholders by the weighted average number of outstanding common shares during the period. Diluted income (loss) per share gives effect to all dilutive potential common shares outstanding during the period. Dilutive loss per share excludes all potential common shares if their effect is anti-dilutive. As of December 31, 2021, there were no potentially dilutive debt or equity instruments issued or outstanding.
Software Development Costs	*Software Development Costs* In accordance with ASC 985-20 "Costs of software to be sold, leased, or marketed" the Company capitalizes software development costs once the preliminary project stage is complete and it is probable that the project will be completed and the software will be used to perform the function intended. Capitalized software represents development costs for external-use software. External-use software is defined as software to be sold, leased or marketed. The Company amortizes these costs over the estimated life of software. The software is still in development and no amortization expense being recognized yet. Amortization will begin once development is complete.
Impairment of Long-Lived Assets	*Impairment of Long-Lived Assets* The Company reviews long-lived assets, including tangible assets and other intangible assets with definitive lives, for impairment whenever events or changes in circumstances indicate that the asset’s carrying amount may not be recoverable. The Company conducts its long-lived asset impairment analyses in accordance with ASC 985-20. ASC 985-20 requires the unamortized capitalized software costs be compared to the net realizable value of that product. The amount by which the unamortized capitalized software costs exceed the net realizable value of that asset shall be written off. There were no impairments recognized during the years ended December 31, 2021 and 2022.
Leases	*Leases* The Company accounts for leases in accordance with ASU No. 2016-02, “Leases”. Under this guidance, lessees (including lessees under leases classified as finance leases, which are to be classified based on criteria similar to that applicable to capital leases under current guidance, and leases classified as operating leases) will recognize a right-to-use asset and a lease liability on the balance sheet, initially measured as the present value of lease payments under the lease. The guidance permits companies to make an accounting policy election not to apply the recognition provisions of the guidance to short term leases (leases with a lease term of 12 months or less that do not include an option to purchase the underlying asset that the lessee is reasonably certain to exercise). If this election is made, lease payments under short term leases will be recognized on a straight-line basis over the lease term. The Company has elected not to apply the standard to short-term leases.
