Policy layer that decides what may be tossed and when, and what the person must acknowledge first. It never gives legal advice; it ships a DRAFT_UNREVIEWED retention table until a Peruvian lawyer or contador reviews it
Each tax-relevant table declares a retention kind (books or tax support) and the column that dates a record; the app computes the earliest toss date from the record's own date, never from a typed-in setting
The clock runs from 1 January of the year after the annual declaration is due (Codigo Tributario art. 87.7 and 44); uncertain points are listed for the lawyer
Default 6 years, 10 years when the business is a retention or perception agent, never shorter than the floors compiled into the code; UNVERIFIED defaults a lawyer must confirm
A longer floor so records that prove a contract are not tossed before civil actions prescribe (Codigo Civil art. 2001: 10 years for personal actions); UNVERIFIED
Books retention while the business lasts and after liquidation
LEGAL-0006○ PlannedLite and ProCore
Accounting books are kept for as long as the business lasts and for 5 years after the recorded liquidation (Codigo de Comercio art. 49); until a liquidation is recorded the books can only be kept (archived)
The business records its liquidation once; the 5-year clock counts from the later of the claimed date and the day it was recorded, and a claim earlier than the newest book entry is refused
A toss of tax-relevant data is refused by the app before the retention period ends and the earliest date is shown; keep (archive) is the only option until then
Data that is not tax-relevant (for example delivery addresses) can be tossed at any time with the acknowledgement; tax-relevant tables are separated from personal data by design
Offline there is no trusted time source: a person who sets the clock forward can unlock a toss. The gates protect against accidental and uninformed deletion and leave a trail; they are not a control against the owner
Archived data and exports stay in open formats and the app can still open them for the whole period (Codigo Tributario art. 87.8: systems in operating condition)
A screen explains that loss or destruction of books must be reported to SUNATPeru’s national tax authority. Simca’s first fiscal pack targets its electronic documents (planned, not built). Glossary within 15 business days and that SUNAT sets the period to redo them; the app does not file anything
