Credit cards management app

No app required...you cannot trust any app in this world...simple solution is to save credit card details as contact and encrypt cvv & expiry date

Example
I saved Cc detail in following format
Expiry + cvv + cc no

I have encrypted expiry and cvv by subtracting from 9

Say cvv is 826 then it becomes 173...to decrypt, i again subtract from 9 in my mind and 173 become 826

Expiry of 11/30 become 8869 and decrypt it by subtracting from 9 and 8869 become 11/30

I have not encrypted cc no as it become very tedious...no one will be able to decode random 23 or 24 digit no

The app doesn't take the full card number or CVV. It's just an expense tracker.
 
Good work, I would suggest, you also compare and make improvements with existing apps such as:
After they grow beyond a point, many of these apps venture into 2 main directions:
- BBPS based bill payment system
- Gift voucher selling.

Because these two are the areas where they get more commissions and profits.
We really need a comprehensive tool that can do: card tracking, reward point tracking, comparison, transfers etc.

Thanks for your feedback. I will check them out and try to improve the app.
