We use this information solely to send you the messages you signed up for, such as appointment scheduling, confirmations and reminders, account or service notifications, responses to your inquiries, and periodic offers about our services.

You can opt out at any time by replying STOP to any message, or reply HELP for help. Message and data rates may apply and message frequency varies. For full details, see our SMS Terms & Conditions.

Google user data

Our MeridianOS platform lets business administrators connect a Google Business Profile using Google sign-in. When an administrator authorizes this connection, we access the following Google user data through Google's Business Profile APIs: the email address of the authorizing Google account, the list of business accounts and locations that account manages, and the reviews on the selected business location, including reviewer names, star ratings, review text, and existing reply text.

We use this data solely to provide the review management features the administrator has enabled: displaying reviews in their dashboard, posting replies they write or approve, posting automated replies according to rules they configure, and sending them notifications about new reviews. When AI-generated replies are enabled, the reviewer's first name, star rating, and review text are sent to our AI text provider to draft the reply. Google user data is never sold, never used for advertising, and never shared with any other third party.

Connection credentials and synced review data are stored securely and retained only while the connection is active. Administrators can disconnect their Google Business Profile at any time from their dashboard, which removes the stored credentials, or revoke access from their Google Account permissions page. To request deletion of previously synced review data, contact us at support@stackdigital.com.

Administrators can also connect a Google Ads account using Google sign-in. When an administrator authorizes this connection, we access the following Google user data through the Google Ads API: the email address of the authorizing Google account, the list of Google Ads accounts that account can access, and advertising performance data for the account the administrator selects, including impressions, clicks, cost, conversions, and campaign names and statuses.

We use this data solely to display advertising performance reports in the administrator's dashboard. We do not create, edit, pause, or delete campaigns, ads, budgets, or any other part of the connected Google Ads account, and we do not use the data for our own advertising, share it with any other third party, or sell it.

Connection credentials are stored encrypted and retained only while the connection is active. Advertising performance data is retrieved on demand when the administrator opens the report and is not stored. Administrators can disconnect their Google Ads account at any time from their dashboard, which removes the stored credentials, or revoke access from their Google Account permissions page.

MeridianOS app

MeridianOS is our business app for Apple devices. We provide it to the businesses whose websites we build and host, and to the employees those businesses invite. This section explains what the app collects and how that information is used. Everything else in this Privacy Policy also applies to the app.

Information the app collects

  • Account information. Your name or username, email address, role, and the website address of the business you sign in to. Passkeys, Face ID and Touch ID are handled by your device and Apple, and we never receive your biometric data.

  • Business records. The information you and your team enter or view in the app, such as customer names, phone numbers, email addresses and service addresses, along with jobs, schedules, estimates, invoices, payments, notes, agreements, employee hours, pay rates and earnings. These records are stored with the business's MeridianOS account on servers we operate with Amazon Web Services.

  • Text messages. Messages a business sends to and receives from its customers through its business number, including photos, are stored with the customer's record so the business can see the full conversation.

  • Photos. The app uses your camera or photo library only when you choose to take or attach a photo, such as for a job note or a message.

  • Voice and MeridianAI. When you start a MeridianAI voice session, the app uses your microphone and sends your speech to our servers and to our speech and AI service providers so it can be transcribed and answered. We keep the text of the conversation in the business's MeridianAI history. We do not store the audio.

  • Requests for access. If you send the Get MeridianOS form, we collect your name, business name, email address, phone number, website and the details you share, and we use them to respond to you and follow up about MeridianOS. Text messages from us require the consent described in the SMS / text messaging section above.

  • Device information. A push notification token so we can send the notifications you turn on. When you set up Tap to Pay on iPhone, we also store a random identifier for that iPhone and its model name, linked to your account, so the business's admins can see and remove the iPhones that take payments.

Payments and Tap to Pay on iPhone

Card payments in the app are processed by Stripe. Card numbers go directly to Stripe, and to Apple when you use Tap to Pay on iPhone, and are never stored by us. We store the payment amount, date, method, status and a Stripe reference with the invoice. Stripe also collects information about the device and how its payment screens are used, to provide the payment service and help prevent fraud, as described in Stripe's privacy policy.

Tap to Pay on iPhone requires location access while the app is open. Stripe uses your location to confirm where in-person payments are taken and to help prevent fraud. You can turn off location access at any time in your device's Settings, which also turns off Tap to Pay on iPhone.

In-app purchases

MeridianAI credits are sold through the App Store. Apple processes these purchases, and we receive only the details needed to add the credits to the business's account, such as the product and transaction identifiers. We never receive your payment card details.

Sample business

Try a sample business uses made-up data that stays on your device and is cleared when you exit. Nothing you enter in the sample business is sent to us.

How app information is shared

We share app information only with the service providers that operate MeridianOS on our behalf: Stripe for payments, Apple for Tap to Pay on iPhone, push notifications and in-app purchases, our messaging and email providers, our speech and AI providers, and Amazon Web Services for hosting. The app contains no advertising and no third-party analytics, and it does not track you across other companies' apps or websites. We never sell information from the app.

Your choices and deletion

You can change location, microphone, camera, photo and notification permissions at any time in your device's Settings. Business admins can remove employees and their access from MeridianOS. To delete your account or request deletion of information associated with it, contact us at support@stackdigital.com. Business records are kept while the business's MeridianOS account is active. When a business ends its service, we delete or return its records on request, unless we need to keep them to meet legal obligations.

MeridianOS is intended for businesses and their employees and is not directed to children under 13.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date.
