Privacy & Security
No background tracking. No keystroke logging. No reading your chat history. Patkan is hardcoded strictly to and stays completely inert until you type //. What you type compiles in RAM and vanishes.
No keyloggers. No background daemons listening to keystrokes. Patkan stays completely inert in memory until you type // at the end of a sentence.
Patkan cannot see your other tabs, bank logins, emails, or browsing history. The browser sandbox strictly confines it to chatgpt.com, claude.ai, and gemini.google.com.
Your rough input compiles in RAM for 200ms and immediately replaces your text. No prompt logs, no chat databases, and zero model training on what you write.
No obfuscated binary blobs. Because you install Patkan unpacked, you can open the folder, inspect every line of plain JavaScript, and verify every network call in DevTools before you click load.
