🏷️ About: Ever wondered how advertisers recognize you across apps and websites? It usually comes down to fingerprinting: small, ordinary details about your device, combined until the mix is rare enough to point back to you. Loupe lets you see those details yourself.
We Investigate the app owner's website (Mysk.co), verify their legitimacy, and uncover hidden scams and complaints.
Loupe does what it says, and does it perfectly. Shining a light on all the info Apple gives away, without permission, to applications.
Provides additional details not previously consider even for someone that has created, developed, and deconstructs many apps…
Shows literally everything an app can track. Truly eye opening.
I always wondered why apps were promoting me to access things that seemed unrelated (or peripheral) to their purpose. Now I know!
Essential for fully understanding what apps can access with no permission. Great work from the devs!
Thank you for making this
