FAQs

How does the privacy of my data work? Do you store my financial information on your servers?

Your calculations stay on your device. dab.tools does not send your financial inputs to our servers for storage — there is no account and no cloud copy of what you enter.

The flexible start date feature is interesting. How does it work for planning my Zakat?

In the Zakat calculator you can choose when your Zakat year starts so planning matches your personal or lunar schedule, then track progress toward your due date.

What is the "split Zakat amount" feature and how can it help me?

This feature takes your total Zakat due and divides it into manageable monthly installments. It provides you with a payment plan, helping you budget for your Zakat obligation over up to 12 months rather than paying a large lump sum all at once.

How does the spreadsheet import/export feature work?

You can export your worksheet to a spreadsheet file for your records, and import a compatible file later to continue where you left off — still stored locally unless you choose to share the file yourself.

Can I really set a reminder for next year with a 10-day deliberation period? How?

Yes. The Zakat calculator can remind you ahead of your next due date and include a short deliberation window so you have time to review assets before confirming.
