Frequently asked questions
General
Do I need to install anything on my computer?
No. Recipe Calculator is a web app. You need a browser and internet.
Does it work on mobile?
Yes. Fully responsive — phone, tablet, laptop, desktop.
Can I use it offline?
No, it needs a server. But you can run it on your own local network using a small always-on machine.
How accurate is it?
As accurate as the data you enter. The math is exact: 4·carbs + 4·protein + 9·fat + 2·fiber. The macros come from your ingredient data — verified against your suppliers' labels or USDA.
Can I export my data?
Yes. Every user can export recipes as PDF. Admin can dump the entire database via cPanel or phpMyAdmin.
Pricing
Is there a free trial?
Yes — email us for a 7-day demo login.
Can I pay by credit card?
Currently bKash only. Credit card support is on the roadmap.
Do I have to subscribe, or can I buy once?
Both. The Single-Site Script is a one-time purchase for ৳150,000, licensed for 3 years. SaaS subscriptions start at ৳1,000 for 3 months (5 recipes).
How does renewal work?
SaaS plans renew at 75% of the package price. For example, a Business plan (৳5,000) renews for ৳3,750.
Technical
Can I host this myself?
Yes — that's the Single-Site product. You own the data on your server.
What if I want to move from SaaS to self-hosted?
We'll export your data as SQL, and you can install the Single-Site version to import it.
Does it work without HTTPS?
Technically yes, but we strongly recommend HTTPS. bKash and email sending work best with it.
Can I modify the code?
The Single-Site license allows you to modify the code for your own use. You cannot redistribute or resell the modified version.
What if I get an error?
Enable debug mode: open app/config.php and set APP_DEBUG to
true. Reload — you'll see the exact error. Turn it back off once fixed.
Can other users see my recipes?
No. Each user sees only their own recipes. Every query is filtered by user ID, both for reads and writes. Isolation is enforced at the database layer.
