Deyn

Deyn is a debt book for Somali shopkeepers and for anyone who lends and borrows among family and friends. Instead of a paper notebook that can be lost, argued over, or read by anyone who picks it up, you keep every debt on your phone, where it is written down the moment it happens. WORKS THE WAY A SHOP WORKS Add a customer, record what they took on credit, and record each payment as it comes in. Deyn shows what is left against each person and what your shop is owed in total. Searching by name, phone number or amount finds the right account in seconds, even with hundreds of customers. TWO LEDGERS, KEPT APART Switch between business and personal at the top of the home screen. Your shop's credit and your own lending never mix: separate balances, separate search, separate reports. In personal mode you track both directions - what people owe you, and what you owe them - with an optional due date and a clear mark when an account is late. NOTHING IS QUIETLY REWRITTEN A debt book is only worth something if nobody can change yesterday's figure. In Deyn every entry is permanent. A mistake is fixed by posting a correction that sits in the history next to the original, showing what changed and when. Nothing disappears, so the record can settle an argument. YOUR EMPLOYEES, WITH LIMITS YOU SET Give a cashier access to record sales and take payments without letting them see your totals, change your settings, or remove anyone. Eleven separate permissions, each one on or off. Every entry carries the name of whoever recorded it, so you always know who wrote what. Removing an employee ends their access and leaves their entries in place. SEE WHERE THE MONEY IS Reports for today, this week and this month: what you collected, what went out on credit, which accounts carry the biggest balances, and which are overdue. Any customer's full history can be exported as a PDF statement and sent to them. INVESTMENTS Track money put into a shop, a vehicle, or land. Money in, money out, and what remains invested - kept separate from debt, because nobody owes anybody anything. YOUR RECORDS STAY YOURS Deyn works entirely offline. Your customers, your balances and your history are stored on your phone and are never uploaded to us. We cannot read them, and we do not keep a copy. A PIN protects the app, and you choose whether it is asked for every time you open it. If you want a safety net against a lost or broken phone, you can turn on backup to your own Google Drive, in a private folder only Deyn can open - not your Drive files, and not visible to anyone else. If you lose the phone, signing in to the same Google account brings your ledger back and lets you set a new PIN. You can delete your account and everything in it from inside the app at any time.
