Frequently Asked Questions

How many devices can I use one license on? +

Each license allows activation on up to 2 devices. If you get a new phone or computer, contact us and we'll reset your activations for free.

Does the app work without internet? +

Yes — 100%. All your data is stored on your device. Internet is only needed to activate your license key (one time) and to use AI features like the receipt scanner.

What's the difference between the demo and a paid license? +

The demo allows 3 invoices, 3 customers, and 3 expenses, and PDF exports have a watermark. A paid license removes all limits and the watermark.

Can I use the same license on both Android and Windows? +

Yes. One license covers both platforms. You can install and activate on one Android device and one Windows PC with a single key.

How do I upgrade from monthly to lifetime? +

Email us at support@donlinestore.com and we'll credit your monthly payments toward the lifetime price.

My license key doesn't work. What do I do? +

Make sure you're copying the complete key including all dashes. Keys look like: LT-xxxxx-xxxxx. If it still fails, contact us with your purchase email and we'll look into it.

Is my business data private? +

Completely. Your invoices, customers, and expenses never leave your device. We have no access to your business data. See our Privacy Policy for full details.

Do you offer refunds? +

Yes — 30-day money-back guarantee. No questions asked. Email support@donlinestore.com with your order details.
