FAQ
Do I need to contact you before ordering?
Yes, please! Every project is unique. Message me first, describe your idea and I will tell you if I can do it, the exact timeline and price. This avoids any misunderstandings.
Will I receive the source code?
Yes, full source code is included in every package. You will own 100% of the code.
What if there are bugs after delivery?
I fix all bugs that are related to my work for free. If something doesn't work as we agreed, just message me and I will solve it as soon as possible. I don't disappear after delivery — your satisfaction is my priority.
What do you need from me to start?
A description of your app idea, any designs or references you have (not required), and your Firebase project access if you already have one set up. We can discuss everything in chat.
Can you publish the app to Google Play Store?
Yes! I handle the full submission process — store listing, app signing, screenshots and policy compliance. Note that you need a Google Play developer account ($25 one-time fee paid to Google).
What if I need changes after delivery?
Each package includes revisions. If you need more, you can purchase additional revisions as an extra. I want you to be 100% satisfied with the result.
