Privacy policy
ZapBounce is operated by Hashlogics, a US LLC. Uploaded addresses are kept until you delete the job, and you can delete it at any time.

1. Two kinds of data
Data about you: your account, your API keys, your billing details. And data about the people on your list, which reaches us because you uploaded it. For the second kind you are the controller and we process on your instructions.
2. What a verification job stores
| Data | Why | Kept for |
|---|---|---|
| The addresses you upload | To verify them | Until you delete the job |
| The result per address | So you can download results | Until you delete the job |
| MX host and response reason | So a result is auditable | Until you delete the job |
| Job metadata: size, time, credits | Billing and your history | Life of the account |
Delete a job with DELETE /v1/jobs/{id} and its addresses and results are removed.
3. What leaves our infrastructure
Verifying an address means asking the receiving mail server about it. That server necessarily sees the address being checked and the address we connect from. We send no message, so nothing arrives in the mailbox. The check is our own, so your list never goes to a third-party verification service.
ZapBounce is hosted in the United States, and a list leaves that region only for that SMTP probe. The 5 sub-processors that host, store, resolve DNS and bill are named on the data processing terms.
4. The website
This site collects what you send through a form and basic analytics about which pages get read. None of it is sold.
5. Your rights, and your list's rights
Delete any job at once with DELETE /v1/jobs/{id}, and its addresses, results and reasons go with it. Export results at any time. If someone on a list you uploaded asks you to erase their data, delete the job that holds their address and remove it from your own copies of the list.
6. How your data is handled
Uploaded addresses are used to verify them and for nothing else. ZapBounce never sells them, never adds them to a shared database, never contacts the people on a list, and never reuses a list to improve the product.
