Privacy

01 / Overview

Who we are and what this policy covers.

LineVerify (“we”, “us”, “our”) operates lineverification.com and the LineVerify API. This policy explains what data we collect, how we use it, and what rights you have. We collect only what is necessary to provide the service.

By using LineVerify you agree to this policy. If you use our API on behalf of a business, this policy applies to your use and you are responsible for making sure your end users know how their data may be processed.

02 / What we collect

Only what we need to run the service.

Your email address and name
For creating your account and billing.
Payment information
Processed by Stripe. We never store card numbers.
API usage logs
Request counts and timestamps for each API key.
Lists you check
The phone numbers and email addresses you upload, paste or send through the API, the list and file name, and the results of every check. We store them with your account so you can come back to your lists and download them.
Feedback you send
Your message and your email address, so we can reply.

03 / What we don't do

No selling, no marketing, no profiles.

We do not sell your data or the phone numbers you submit to anyone
We do not use submitted phone numbers for marketing
We do not share your lists with anyone except the providers that run each check
We do not build profiles
We keep nothing about the people on your lists beyond the results shown to you, and only until you delete the list.

04 / Who we share with

The processors that make each check work.

Each phone number you check is sent to Twilio, Trestle, Telnyx, RealValidito and IPQualityScore. Each email address is sent to Kickbox. They receive the numbers and addresses only, never your name, email or list name.

05 / Do-not-call and lawsuit risk

Information to help you decide, not legal advice.

LineVerify shows do-not-call status and lawsuit risk (TCPA risk) as information to help you make compliant outreach decisions. This data comes from RealValidito and reflects the federal Do Not Call registry, state do-not-call lists and known TCPA litigators at the time of the check.

LineVerify does not guarantee legal compliance. You are solely responsible for complying with the Telephone Consumer Protection Act (TCPA), the FTC Do Not Call rules and any state telemarketing laws.

06 / How long we keep data

Until you delete it.

Lists and results
Until you delete the list or your account. Deleting a list removes its numbers, emails and results immediately.
Account data
Until you delete your account. Deleting it immediately removes your lists, results, API keys, API logs, balance and feedback.
API request logs
Until you delete your account.
Billing records
Payment records are kept for as long as financial regulations require, up to 7 years.

07 / Security

How your data is protected.

All data is sent over TLS 1.2 or later. Your lists and results are encrypted at rest and only your account can see them. API keys are hashed at rest. Payment data is tokenized by Stripe and never touches our servers.

08 / Your rights

See, correct or delete what we hold.

Depending on where you live, you may have the right to access, correct or delete personal data we hold about you. You can delete your data yourself at any time. For anything else, email privacy@lineverification.com.
