Free trial abuse prevention for SaaS
A free trial or a free tier is a growth tool until the same person keeps restarting it. FingerPrint Checker ties each trial to the device, normalised email and household, and can cap how often an anonymous visitor uses a free tool.
Abuse patterns we see in this industry
- Serial trials with throwaway or plus-tag email addresses.
- Free-tier limits reset by creating another account.
- Pre-login forms that send verification messages you pay for.
- Scripted sign-ups that burn compute credits.
How FingerPrint Checker maps to them
- Free trial abuse: one trial per device, email and household.
- SMS and OTP fraud: a per-device quota before you send a message.
- New account fraud: human checks for new devices.
What it does not do
FingerPrint Checker is a device and household signal that decides whether one device may claim one thing. It is not identity verification, and it does not replace the checks your regulator or payment provider requires.
Frequently asked questions
Can I still let genuine returning users start again?
Yes. Release a claim when you decide a trial should be given back, for example after a refund, within the bound that stops a claim and release loop.
