FAQ
Since this is a single file, where is my data saved?
Your transaction data is saved directly inside your browser using LocalStorage. This means the data is secure, private, and never leaves your device. It is not saved on any external server or database, which is why there are no monthly fees!
Does this app require a website or hosting?
No. You can open the HTML file directly on your desktop or mobile browser. If you order the Premium Tier, I offer a Hosting & URL Setup extra service to give you a permanent web link, but it is not required for the app to function.
What if I lose my phone? Will I lose all my invoice history?
Yes, if you use the Basic or Standard tiers, the data is tied to the specific browser on that specific device. If you want a backup, you must purchase the Premium Tier or the Data Export Feature extra service, which allows you to download all your history to an Excel-friendly file for safekeeping.
Can I add my business logo and custom colors?
Absolutely. The Basic Tier ($80) and higher all include custom branding where I integrate your logo and adjust the app's colors to match your brand identity.
Is it truly a one-time payment?
Yes. You pay once for the custom development, and the app is yours forever. There are zero hidden monthly costs, subscriptions, or future fees from me.
