Common complaints we solve
"Same fingerprint on different devices"
Corporate/school environments with identical hardware produce identical hashes. Neoprint's weighted ID prioritizes high-entropy signals, reducing collisions.
"Different fingerprint after browser update"
A single signal change produces a completely new hash. Neoprint's stable ID uses only update-resistant signals (math, GPU, fonts).
"Different fingerprint in incognito"
Storage quotas and permissions change in private browsing. Neoprint's incognito-resistant mode excludes volatile signals.
"HTTP and HTTPS give different results"
Some APIs require secure context. Neoprint automatically filters collectors by protocol.
"No way to detect spoofing"
Anti-detect browsers spoof individual signals but create inconsistencies. Neoprint cross-references signals to detect tampering.
"I lose users after browser updates"
Neoprint's lifecycle module auto-links old and new fingerprints with a probability score.
