Frequently asked questions
Cleon1 focuses on direct phone enrichment for B2B prospecting teams. You can run single-contact searches, bulk CSV enrichment, or API requests depending on your workflow.
You can add more verified phone credits anytime with our top-up options. Your plan continues working normally — you just won't be able to reveal new verified phone numbers until you add credits or your next billing cycle begins.
Unlike most competitors who expire credits at month end, Cleon1 credits roll over. Verified phone credits are valid for 2 months on monthly subscriptions and 12 months on annual subscriptions. No 'use it or lose it' pressure. If you cancel, credits reset to 0 at the end of your billing period.
Yes. Upgrade instantly and get immediate access to your new plan's features. Downgrades take effect at your next billing cycle. No penalties either way.
We offer a 14-day money-back guarantee on your first paid month. If Cleon1 isn't right for you, email support for a full refund — no questions asked.
Yes. Cleon1 is GDPR and CCPA aligned. We only surface publicly available business contact information and maintain strict data handling practices.
