SMS Privacy Policy

Holstein Inc. DBA “Zerva” · New York · Last updated September 22, 2026

This policy explains how Zerva handles mobile phone numbers and text-messaging consent for the messages Zerva sends to its own customers: the owners, managers and staff of the businesses that subscribe to Zerva software. It does not cover messages a Zerva customer sends to its own guests; those are sent under that business’s own carrier registration, and that business’s own privacy policy governs them.

Who is responsible for these messages

Zerva — Holstein Inc. DBA Zerva, a New York corporation — is the sender. Every message in this program begins with “Zerva:” so you always know who is texting you. Zerva decides when these messages are sent and is responsible for their content.

What we collect

• Your mobile number, and the name and business you gave when you signed up.
• Your consent record: the date and time you checked the consent box, the IP address it came from, and the exact disclosure text shown to you at that moment.
• Your account status: whether your setup form is finished and whether your account is live, which is what the reminders are based on.
• Message delivery data: timestamps, delivery status, and any replies you send us, including STOP, HELP and support messages.

How we use it

Only to send you the messages described in our SMS Terms — setup reminders, notice that your account is live, and replies to support requests you send us — and to keep a record that you consented. We do not send marketing or promotional text messages through this program, and we do not use your number for advertising.

Who we share it with

We share your number only with the telecommunications providers that deliver the message: our messaging provider, Telnyx, and the mobile networks. We do not sell personal information, and we do not share mobile information with third parties or affiliates for marketing or promotional purposes.

Opting out

You can cancel at any time by replying STOP to any message. We will send one final message confirming that you have been unsubscribed, and you will receive no further texts from us unless you opt in again. For help, reply HELP or email inquiries@getzerva.com.

Message frequency and cost

Message frequency varies and depends on your own account activity — typically a few messages while your account is being set up, then only replies to support requests you start. Message and data rates may apply. Carriers are not liable for delayed or undelivered messages.

Retention

We keep your number and consent record for as long as you subscribe to Zerva and as long as needed to prove consent and meet legal obligations, then delete or anonymize it. Opt-out records are retained so we can continue honoring your request.

Security

Data is encrypted in transit, access is restricted to authorized staff, and credentials are stored encrypted at rest. No method of transmission or storage is completely secure.
