Inux PDF - The privacy-first PDF toolkit — no cloud, no subscription

Hi everyone! I'm Inux. I'm a solo developer, learning as I go and building apps (mainly for Android). No team, no funding, just me coding at night, haha. I've managed to create my first Android app, and I'm really happy with it because I feel like I've made something genuinely useful. I created "Inux PDF" because I was fed up with PDF apps that force you into a monthly subscription just to merge two files, or that upload your documents to a server to "process" them, or bombard you with ads. That didn't sit right with me, so I developed a tool that handles everything locally on your phone: merging, splitting, signing, OCR, compressing, filling out forms, and even reading PDFs aloud. All without needing an internet connection. Whether for studying, hobbies, or work, I feel like this will really help people or at least, that's my goal. It doesn't require an account, has no ads, and doesn't use the cloud. There are free tools available, plus some PRO features that you pay for once and own forever. Since I'm developing this entirely on my own, I personally read every comment. I'll likely include user suggestions in the next update or at least try to, since I'm still learning. I'm curious: Which PDF tool do you use most in your daily life? Is there a feature you've always wanted in a PDF app but never found? Thanks for taking a look! I'll reply to everyone as soon as I can, and if you give it a try, I'd love to hear what you think!
