Questions about AsalBook
How does AsalBook work out the interest?
Choose rupees per 100 a month, % a year or a fixed amount a month, and how months are counted (exact days, calendar month, full or half month). Payments go to interest first and then to the amount given, or as you choose.
Is AsalBook free?
Every feature is free for the first 45 days, with no card needed. After that, a plan through Google Play keeps adding entries: ₹59 a month or ₹499 a year. Without a plan the app becomes read-only and nothing is deleted.
Can I keep a record of gold and silver kept as security?
Yes. Add the item, metal, purity and weight in grams or tola, with photos. AsalBook makes a receipt when items are kept and when they go back.
Who can see my records?
Only you. The book is stored in an encrypted database on your phone and opens with your PIN or fingerprint. Duttatech Solutions has no AsalBook server; a Google Drive backup goes to your own Drive, encrypted with your PIN.
Does AsalBook lend money?
No. AsalBook only keeps your records. It does not lend money and does not offer, arrange or advertise loans.
Does it work without internet?
Yes. AsalBook works fully offline. Internet is used only to back up to your own Google Drive, restore on a new phone or buy a plan.
