Quick answers
When are credits consumed?
Credits are consumed only when you download a list. Searching, previewing, and filtering are always free. For Tech Lookup, re-downloading the same report within the same billing cycle does not consume additional credits.
What is a lead list?
A lead list is a saved, downloadable report built from one search with every website and its enriched company data matching your chosen technology, keyword, country, or filter combination. Each lead list can hold up to 1 million sites and be rebuilt against fresh data for a month.
Can I cancel my subscription anytime?
Yes, there are no contracts on any plan and you can cancel anytime from your dashboard. You will retain access through the end of your current billing cycle.
Do all plans include the same data?
Yes, every plan searches the same full index of 425 million websites and 70,000+ technologies. Plans differ only in volume: how many lead lists you can build, how many bulk enrichment credits you get, and how many user seats you have.
What is your refund policy?
StackScan offers a 14-day money-back guarantee on every paid plan. You can submit a refund request from the Billing section and they will respond within 24 hours.
