ZendSMS app privacy
This policy explains how Diana Host Limited, operating the ZendSMS brand, handles merchant and recipient information when a business installs or uses the ZendSMS app for an online store.
Effective: September 11, 2026
Merchant and customer data is not sold.
App data is used to send, report, support and secure requested SMS.
Platform privacy requests for customer and shop data are supported.
ZendSMS is a brand operated by Diana Host Limited. This policy applies to the ZendSMS online-store app, including an installation obtained through the Shopify App Store, and works together with the general ZendSMS Privacy Policy.
When a merchant installs or uses the App, we may process the minimum data needed to authenticate the store and provide the selected functions.
To send a notification selected by the merchant, the App may receive order and customer fields from authorised platform events.
We use App data only to operate the merchant’s requested messaging workflow and meet security, support, platform, telecom and legal obligations.
Destination numbers and message content are transmitted to the ZendSMS API, mobile-network and approved routing or technology providers only as needed to deliver, secure and report the requested message. We do not sell merchant or recipient information for independent marketing.
We retain App settings, logs and related records only for the period reasonably needed for service operation, billing, support, fraud prevention, dispute handling and applicable platform, operator or legal requirements.
The merchant decides which customers receive messages and remains responsible for lawful authority, recipient consent where required, approved sender identities and templates, accurate destination numbers, promotional opt-out handling and compliance with BTRC, operator and applicable legal requirements.
We use access controls, logging and reasonable technical and organisational safeguards designed to protect App data. Merchants must protect store accounts, ZendSMS credentials and administrator access, rotate exposed credentials and notify us promptly of suspected misuse.
The App is free to install unless the listing states otherwise. SMS use is charged against the merchant’s ZendSMS account under the applicable quotation, rate and ZendSMS Terms of Service. The ZendSMS no-refund rules apply to SMS credits and paid services.
Merchants or authorised data subjects may contact admin@zendsms.com about App data. We may verify identity and authority before acting. We will revise the effective date when this policy is materially updated.
