    Why you can trust the result

    A program calculates; no AI guesses. The deadline comes from fixed rules we checked against the text of the law – every rule is documented with the date we read it and secured by thousands of automatic tests.

    The safe side. Where two readings are possible, we show the earlier end and say why it may be later. A day too early costs nothing – a day too late can cost you your objection.

    Your data stays with you. The calculators run entirely in your browser. Nothing is sent, nothing stored, no cookies, no access logs.

    irot Brief gives general information and calculates deadlines under the statutory rules. It does not check whether a decision is correct and is not legal advice. Every letter page names who can advise you.

    Do you advise people with official letters?

    Migration counselling, social and debt advice, integration courses: irot Brief calculates deadlines reliably and explains letters in the language of the people you help.
