DuplicateFinder Mini FAQ
Is DuplicateFinder Mini really 100% offline?
Yes. MD5 + perceptual hash (pHash). Finds duplicate photos & large files in seconds, fully offline. Supporter key verification uses embedded RSA public-key crypto — no network needed.
Can I use it without paying?
Yes. All features are permanently free — no trial, no watermarks, no limits. A $2.99 supporter key only removes the occasional pop-up reminder and adds a supporter badge.
How does the supporter key work?
After your $2.99 support, Lemon Squeezy instantly emails you a key like
DPFD-xxx-yyy.
Paste it into the app to verify offline in 0.001 seconds, or use the "Launch & Apply Key" deep-link.
