I created a tool named Logo Spark(https://logospark.starta.trade) for logo design inspiration and launched it on Hacker News a week ago.

As a programmer, this is my first independently developed product. I've learned a lot in the process, including understanding user needs, defining products, and marketing. Of course, I'm still a novice in these areas.

I'd like to share what I consider to be the most important lessons, as they will help me in future product development:

1. Using unfamiliar technology for the sake of coolness led to bugs: My product's core functionality has undergone extensive testing before and after launch, so there haven't been any major issues this week. The main problem was with the product landing page; in pursuit of a cool effect, I used a technology I wasn't very familiar with. Users immediately reported that the page scrolling behavior was strange and the experience was poor. I realized where the problem was and immediately removed the odd scrolling effect. In fact, I thought the cool effect would add points to my website, but it failed; using unfamiliar technology carries risks.

2. Users will object to my use of arrogant marketing terms: I claimed on my website that my product would be better than traditional logo design methods, but in reality, I had no data or evidence to prove this. Users also pointed out this issue. In fact, my product, like other traditional tools, is an auxiliary process in logo design.

3. The product requires login and payment to use, but lacks clear instructions, which annoys users: My product design requires login and payment to use, but there was no clear indication anywhere on the website, leading users to feel deceived. In response, I urgently added a notice at key points stating that login and payment are required to use the product and added 10 free usages as compensation for all registered users. New registrants receive 5 free usages to improve their experience.

4. Privacy policy and terms of service are controversial: Users expressed dissatisfaction with certain clauses in the privacy policy and terms of service, especially regarding the product's use of personal information and copyright issues with generated logos. I don't understand legal and compliance issues, and for now, I can only modify them based on other products' statements. I think this is something most products will encounter. I thought users wouldn't care about these terms (I never read them), but in fact, agreements are important, users do care, and developers need to balance the rights of users and the product well.

Thank you to all the friends who have given me feedback, and I hope my lessons can be helpful to everyone as well.
