    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Calculate how much each of 6 Czech banks will lend (or whether a requested amount gets approved) from household income, expenses, debts and property, using each bank's own credit methodology (DSTI, DTI, LTV, living costs, recognition of self-employed, pension, rental and other income). No personal data needed: ages and amounts only.

  • compare_mortgagesCompare the monthly payment, interest rate, RPSN (APRC), total cost and interest of a given mortgage amount across 6 Czech banks, sorted from cheapest.No findings

    Why it is in this group

    • The name "compare_mortgages" says "compare": a word for reading.
    Description, as the server wrote it
    Compare the monthly payment, interest rate, RPSN (APRC), total cost and interest of a given mortgage amount across 6 Czech banks, sorted from cheapest. Applies each bank's LTV and small-loan surcharges and product limits (not creditworthiness). Above 80 % LTV banks lend only if all applicants are under 36 (set all_applicants_under_36). Use for 'which bank is cheapest for X CZK'.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
