Sanitation-day checklist. A sanitation day is held once a month: a deep clean while the establishment is closed. The checklist records completion of each item.
A sanitation day is a scheduled production shutdown for deep cleaning. The WeSetup checklist includes all required areas and becomes a completed report for inspection.

The same file the service provides to an inspector. The data is fictional: the organization “Ромашка” and five employees.
Required fields: Sanitation day date; List of procedures marked as completed; Responsible person for each item. An empty field is equivalent to an incomplete log for an inspector, so use a dash deliberately and include an explanation.
According to the HACCP plan: the frequency is set when describing the control point and justified in the plan itself.
SanPiN 2.3/2.4.4282-26. Include the regulatory reference on the title page so the inspector can immediately see why the log is kept.
Yes. SanPiN 2.3/2.4.4282-26 does not require paper: the important points are being able to see who made an entry and when, and preventing unnoticed retrospective changes. For an inspection, print the electronic log for the required period.
Inspectors usually request records for the last 12 months, so one year is a practical minimum. Keep logs connected with a food poisoning investigation or a complaint until the proceedings are closed.
