Frequently asked questions
Will my lead contact details be exposed?+
No. Lead names, emails, and phone numbers stay in your browser. JAD Apps never receives the file.
How are duplicate leads detected?+
Two rows are considered duplicates when all columns match after whitespace trimming. To dedupe by email or phone only, pre-trim the export to those columns first.
Can I clean a lead list larger than 2 MB?+
The free tier handles files up to 2 MB. Pro removes the limit and is suited to multi-thousand-row lead lists.
