JK Codes is an independent studio making small, fast, private software for Android, Windows and the web. Every app runs on your device, asks for no account, shows no ads and sends nothing home.
On Android, Windows and the web. Each one solves a single annoying problem well, without handing your data to a cloud you never asked for.
Sticky notes that float on top of any app.
Write a note, tap Float, and it stays visible above your browser, chat or trading app. Checklists, voice memos, drawings, handwriting scan, reminders that read aloud. 100% offline, 15 languages.
The heavy-sleeper alarm that will not stop until you are actually up.
Walk 100 metres, scan a QR code in another room or solve a puzzle to switch it off. 20 sensor-verified challenges with anti-cheat, rationed snooze, and zero data collected.
Your whole PC, at a glance. An always-on-top system monitor and mini Task Manager.
Live CPU, RAM, GPU, disk, network and temperature in one compact card that stays above your other windows. Grouped processes you can end in one click. Under 1 MB, native C++.
Offline voice dictation. Hold a key, speak, and the words land at your cursor.
Whisper and NVIDIA Parakeet speech models running entirely on your CPU. Works in any app, no internet, no account. Your audio never leaves the PC.
30 PDF tools that run in your browser. Nothing is ever uploaded.
Merge, split, compress, convert, OCR, sign, edit, protect. Files stay on your device because there is no server. The Android app adds a camera document scanner and carries no ads.
A video and music player that plays almost anything and sends us nothing.
MKV, HDR, AV1 and styled subtitles, on-device AI subtitles and translation, SMB and DLNA shares, Cast, and a 10-foot Android TV interface. No ads, no account.
These are not marketing lines. They are constraints every JK Codes app is checked against before it ships.
No ad network, no crash reporter, no advertising ID. If an app needs the network at all, the reason is written down in its privacy policy in plain English, along with any third-party component that reports anywhere on its own.
Kotlin and Jetpack Compose on Android. C++ and .NET on Windows. AllPDF.tools is a web app on purpose, so the same code runs in your browser and in its Android app, still entirely on your device.
Every app does one job and does it completely. Small downloads, fast starts, no background services you did not ask for, and every release is tested on real hardware before it ships.
Every JK Codes app is published under the same developer name in the official store for its platform, so updates arrive the safe way.
StickyHover, NeuroAlarm and Lanelo today, AllPDF.tools next, published by JK Codes.
MiniMon and Curlew, published by JK Codes.
Planned. New platforms follow the same rules as the first two.
AllPDF.tools runs in any modern browser. Nothing to install, nothing uploaded.
Bug reports, feature requests, refund questions, privacy requests. A human reads every message, and you will never be asked to create an account to get help.
