Frequently Asked Questions
Everything you need to know about AccBook — general and technical.
General
Is AccBook free?›
Yes, completely free. No ads, no premium plans, no hidden cost.
Is my data private?›
Yes. Only you can see your data. It's never shared, sold, or accessed by anyone else — including us. Each user's data is completely isolated.
Can my family use AccBook?›
Yes. Each family member creates their own account. All accounts are independent — no one can see another person's expenses or income.
What if I forget my password?›
Click "Forgot password?" on the login page. Enter your email address and we'll send a secure reset link within a minute. The link expires in 30 minutes.
Does AccBook work on mobile?›
Yes. AccBook is fully mobile responsive. Open
accbook.in in your mobile browser (Safari on iPhone, Chrome on Android) and add it to your home screen for an app-like experience — no App Store needed.
Can I export my data?›
Yes. Go to Settings → Export Full Backup to download all your expenses, income, categories and credit cards as a JSON file. You can also export as PDF from the Reports page.
Which currencies are supported?›
AccBook supports INR (₹), USD ($), EUR (€), GBP (£) and several others. You can change your currency anytime in Settings → Preferences.
Is there a dedicated mobile app?›
Not on the App Store or Google Play Store yet. AccBook works as a Progressive Web App (PWA) — add it to your home screen from your mobile browser for a full app-like experience with offline support.
Technical
Where is my data stored?›
Your data is stored securely on servers. All data is kept in a MySQL database with user-level isolation — no cross-account data access is possible.
How are passwords stored?›
Passwords are hashed using bcrypt — an industry-standard, one-way encryption algorithm. We never store plain text passwords. Even if our database were compromised, passwords would not be readable.
Is the connection secure?›
Yes. AccBook uses HTTPS with SSL/TLS encryption for all data transferred between your device and our servers. Session cookies are HTTP-only and marked Secure.
How does email verification work?›
When you sign up, we send a 6-digit OTP to your email. You must enter this code to complete registration. The OTP expires in 10 minutes. This ensures only valid email addresses can create accounts.
Does AccBook work offline?›
Partially. AccBook requires an internet connection to sync data with the server. However, the app shell loads from cache so you can view previously loaded data while offline. Saving new expenses requires internet.
