BEFORE YOU BEGIN

Matching is a suggestion. Review the details before treating two contacts as the same person.

Your file stays local: The checker processes your CSV in your browser and runs without analytics. Privacy details
Keep a record of your decisions: The audit includes original values from candidate rows. The reviewed CSV keeps the selected row; it does not combine fields.
Your CRM stays unchanged: DedupeSafe does not connect to HubSpot. Reimporting a smaller CSV does not merge or delete existing CRM records.
