How this calculator works — and how we protect your privacy

This page explains, in plain language, how the calculator on this site works and why we built it the way we did. It does not make any religious ruling — it simply describes the tool.

Everything runs on your device

When you enter an estate and a list of surviving family members, the shares are worked out inside your own browser. There is no server in the loop doing the maths, because the maths does not need one. The rules of fixed-share inheritance are deterministic: the same inputs always produce the same output, so the whole engine ships to your device and runs there.

That has a direct privacy consequence. The figures you type — what your home is worth, who is in your family, what debts are outstanding — never travel across the network. They stay on the one device in front of you.

No accounts, no tracking

We deliberately collect nothing:

• No sign-up. You never create an account, so there is no profile to leak.
• No analytics or advertising on the calculator. We do not watch what you do.
• No third-party scripts reading your inputs.

The only data the app keeps is your own session, saved locally (in your browser's storage) so that a refresh or a return visit does not wipe your work. You can clear it at any time, and clearing your browser data removes it for good.

Why "privacy-first" matters here

Inheritance is among the most sensitive subjects a family deals with. It touches money, mortality, and relationships all at once. A tool that quietly uploaded those details — or built an advertising profile from them — would be doing something quite at odds with the trust the subject deserves. Computing locally is the simplest honest answer: if the data never leaves, it cannot be misused.

What the tool is — and is not

The calculator is an educational aid. It illustrates how fixed shares and the residue are distributed under the rules it implements, and it is a good way to build intuition before a real conversation. It is not a fatwa and not a legal ruling. Real estates carry details — disputed assets, blended families, cross-border property, outstanding obligations — that only a qualified person can weigh for your specific case.

When you are ready to move from "roughly how does this work" to "what exactly applies to us," that is the moment to bring a qualified scholar, and where the law of your country applies, a qualified lawyer or notary, into the conversation.
