// PRYSM — APPPRYSM
Privacy scanner for apps, websites, and QR codes.
See what data they collect before you trust them. Powered by AI. Your data never leaves your device.
// WHAT IT DOES
Prysm scans anything you point it at — App Store apps, websites, QR codes, barcodes — and tells you exactly what data they collect, who they share it with, and how they track you.
Every scan runs through AI analysis. On iOS 26+, the analysis happens entirely on-device using Apple Intelligence — nothing leaves your phone. On older devices, Prysm uses Claude Haiku with the minimum data needed, then discards it.
No account. No subscription. No analytics. The app that watches the watchers.
// FEATURES
APP SCANNERPaste any App Store link. Prysm pulls the privacy labels, matches known tracker SDKs, and scores the app on a 0–100 scale.
WEBSITE SCANNEREnter a URL. Prysm fetches the page, detects tracking scripts, reads the privacy policy, and runs AI analysis on it.
QR & BARCODEScan any QR code or barcode with the camera. Prysm identifies the content type and assesses privacy implications before you open it.
AI ANALYSISOn iOS 26+, analysis runs entirely on-device via Apple Intelligence. Falls back to Claude Haiku for older devices. No data stored.
TRACKER DATABASE50+ known tracker SDKs matched by script patterns, App Store labels, and identifiers. Facebook, Google, TikTok, session recorders, and more.
PRIVACY SCORE0–100 score with letter grades. Deductions for tracking, identity linking, location access, and ad networks. Bonuses for good practices.

// PRIVACY
Prysm has no backend. Scan results are stored locally on your device using SwiftData. The scan counter lives in your Keychain, tied to your Apple ID. On iOS 26+, all AI analysis runs on-device via Apple Intelligence — nothing is transmitted. On older devices, the website's public HTML and privacy policy text (not your data) are sent to the Anthropic API for analysis and immediately discarded.
No analytics. No crash reporting. No accounts. No telemetry of any kind.
