Finx — Device Detector
Last Updated: May 23, 2026
At Finx (“App”, “we”, “our”, or “us”), protecting your privacy is a core principle. This Privacy Policy explains what information we collect, how it is used, and the choices available to you.
By using Finx, you agree to the practices described below.
Finx is designed to perform detection and analysis directly on your device.
We do not collect, store, transmit, or access:
Your name, email address, or personal profile information
Device scan results or detected device lists
Nearby Bluetooth or Wi-Fi identifiers
Signal strength data from scans
Photos or video captured during scans
Precise location information
Camera footage or environmental recordings
All detection processing happens locally on your device.
Subscription Management (RevenueCat)
If you purchase or restore a subscription, subscription processing is handled by RevenueCat.
RevenueCat may process:
Anonymous application user identifier

App version and platform information
RevenueCat does not receive your Apple ID, payment details, or personal scan data.

Finx is not intended for children under 13 years old.
We do not knowingly collect personal information from children. If you believe information has been submitted by a child, contact us and we will address the request promptly.
Because Finx does not collect scan or personal usage data, there is generally no user content retained.
Subscription-related information retained by RevenueCat follows their own retention policies.
Depending on your region, you may have rights to:
Access information associated with you
Request deletion
Correct inaccurate information
Request data portability
Object to certain processing activities
To submit a request, contact us using the support link on the App Store listing.
We do not sell personal information.
Where applicable, processing is based on:
Contract performance (subscription services)
Legitimate interest (maintaining service reliability)
We implement reasonable safeguards to protect information.
Because scan analysis remains on your device, exposure of sensitive data is minimized.
No transmission or storage system can guarantee absolute security.
Anonymous subscription information processed by service providers may be transferred internationally in accordance with applicable data protection laws.
We may update this Privacy Policy periodically.
Updates will appear under the Last Updated date. Continued use of Finx after updates indicates acceptance of the revised policy.
