Checksum detectors on every plan. Names need Starter or above.
Free validates every deterministic detector. Starter, Pro and Business add language-model detection of names, organisations and locations — then team size, upload size and session key grow.
Need more than Business gives you?
Dedicated deployment, custom limits and compliance support for regulated organizations — priced around your actual usage, not a seat count.
- Dedicated deployment options, including on-premise
- Custom session retention and upload limits
- SOC 2 Type II (in progress), ISO 27001 & HIPAA/BAA (planned)
- Dedicated onboarding and support
Common questions.
Plans, detectors, storage and deployment — the things people ask before they sign up.
Can I switch plans later?
Yes. Start on Free and move up to Starter, Pro, Business or Enterprise whenever your team needs it — nothing about a masked session changes when you do.
What counts as a "detector"?
A detector recognizes one kind of sensitive value and validates it — checksum, format — before masking it, so a random string is never flagged by mistake.
What's the actual difference between Starter, Pro and Business?
The same detectors and NLP-powered name/org/location detection run on all three — what scales is team size, upload size and how long a session key stays valid, plus faster support as you go up.
What does a team share?
One workspace and one invoice. Every member gets their own login, sessions and API keys; the plan's limits — upload size, session length — apply to everyone. Invite colleagues from the app; seats are billed monthly per user.
Is my data ever stored?
The mapping between a token and your real value lives only in memory for the length of a session, then it's gone. We never see or keep your underlying data.
Do you support on-premise deployment?
That's part of the Enterprise plan. Reach out and we'll walk through what a dedicated deployment looks like for your infrastructure.
Do you offer a discount for annual billing?
Not yet — pricing today is monthly only. If that changes we'll list it here first.
