Privacy policy
Effective: 20 July 2026 · Last updated: 20 July 2026
Who we are
lunalink.ai operates Sentira, a cross-channel customer engagement platform connected to your Shopify store. This policy explains what data Sentira accesses — including data about your customers — why, and how it's handled. Questions: hello@lunalink.ai.
What Sentira accesses (Shopify permissions)
- Read customers — to build the unified customer profiles Sentira segments and messages run on.
- Read orders — purchase history, used for segmentation (for example, past-purchaser or win-back segments) and for measuring what a campaign or flow drove.
- Read checkouts — to power behaviour-based flows such as abandoned-checkout messaging.
- Read products — catalogue context (titles, images, prices) for referencing products in campaigns and segments.
- Write pixels — to register an on-site tracking pixel that reports storefront behaviour back into a customer's profile.
Sentira does not request access to your store's financial or payment data beyond order records.
Data we hold about your customers
Sentira is a customer data platform — unlike a tool that only touches your product catalogue, its job is to unify your customers' data so you can message them. Concretely, we hold: name, email address, and phone number (when provided); order and checkout history; on-site behavioural events from the tracking pixel; and consent status for email and SMS, recorded as a full history of changes — not just a current yes/no. Where the same person appears more than once across your data (for example, a guest checkout and a later account), Sentira resolves these onto one profile.
Consent-gated messaging
Sentira checks consent before every send: a customer who hasn't opted in to email or SMS, or who has opted out, is excluded automatically, not just flagged for you to catch. SMS messages include opt-out instructions (reply STOP) as standard, and an opt-out is honoured immediately.
AI processing
Sentira's in-dashboard assistant (Luna) uses OpenAI to help you draft segments, message templates, and campaigns or flows, based on a summary of your account's data and the questions you ask it. Luna can only draft — it has no ability to send a message or activate a flow; a person always takes that step. OpenAI does not use this data to train its models (standard API terms).
Sub-processors
Sentira shares data with these providers only as needed to operate:
| Provider | Purpose |
|---|---|
| Render | Application hosting and background workers (US). |
| Supabase | Managed PostgreSQL database (US). |
| Resend | Email sending and delivery/engagement tracking (opens, clicks, bounces). |
| Twilio | SMS sending, delivery status, and inbound STOP/HELP handling. |
| OpenAI | Luna, the in-dashboard drafting assistant. |
| PostHog | Product analytics (shop domain only, no customer data), if enabled. |
| Sentry | Error monitoring (no customer data), if enabled. |
| Shopify | The platform your store runs on; source of the order, checkout, and customer data above. |
Data retention
We retain customer profiles, event history, and consent history for as long as your store is connected, so segments and flows stay accurate. If you disconnect your store, we stop collecting new data; existing data is deleted on request (see below) or after a reasonable period of inactivity.
Your rights and data deletion
You, or one of your customers, can request access to or deletion of the data described above at any time by emailing hello@lunalink.ai. We'll act on a deletion request by removing the identified customer's profile, event history, and message history from Sentira.
Data location and security
Sentira's data is stored in the United States on Render and Supabase infrastructure, encrypted at rest and in transit, on a database dedicated to Sentira — not shared with other lunalink.ai apps. Access is limited to the running application and the maintainers who operate it.
Billing
Sentira does not have published pricing yet. This policy will be updated to describe payment processing once billing is live.
Changes
We'll post any changes to this policy on this page and update the date above.
