Introduction
Two promises define AppScreenshotsKit: your data never leaves your browser, and your exports never carry a watermark. These aren't features - they're principles. And they're delivered without requiring an account, a payment, or a reason.
This blog walks through both promises in concrete, technical detail - and explains why they matter more than most developers realize.
The Privacy Promise: Technical Reality
When you upload a screenshot to AppScreenshotsKit, the file is read by the browser's FileReader API and loaded into an HTML5 Canvas element. The canvas compositing - device frame overlay, background application, text rendering - all happen using JavaScript executed on your device.
At no point is any network request made that includes your image data. You can verify this yourself: open DevTools > Network tab, upload a screenshot, and observe that no image data is transmitted to any server.
- FileReader API - local file access only
- Canvas API - GPU-accelerated local rendering
- No fetch() or XHR requests - your images never leave the browser
- No WebSocket - no real-time server connection
- No localStorage persistence - nothing stored after tab close
- No telemetry on screenshot content - ever
The Watermark Promise: Why It's Unconditional
Most free screenshot tools use watermarks as a paywall mechanism. Remove the watermark by upgrading to Pro. This is rational product design - but it creates a two-tier system where free-tier exports are literally branded with inferiority.
AppScreenshotsKit doesn't have a Pro tier. There is no upgrade path that watermarks are designed to push you toward. The tool is free, the exports are clean, and that's the complete business model.
No Freemium Manipulation
AppScreenshotsKit will never add watermarks to free exports. The tool exists to help developers - not to extract money from them through frustration mechanics. That's a design decision, not a temporary promotional state.
