What Purser collects, why, where it is stored, how long it is kept, and how to get it deleted.
Last updated 15 July 2026
This policy explains what Purser ("we", "us") does with data when you install the Purser app into your Shopify store. It is written to be read, not to be survived. If anything here is unclear, email support@gopurser.com and we will explain it in plainer words and then fix the wording.
What we collect through Shopify's APIs
- Shop details: your myshopify.com domain, shop name, currency, and the locations you hold stock at.
- Products and variants: titles, SKUs, barcodes, unit cost and price.
- Inventory levels: how much of each variant is on hand, per location.
- Your app subscription status, so we know which plan you are on.
We request no access to your orders, your customers, your marketing data, your themes or your storefront, and we cannot read them.
What we collect directly from you
- Suppliers you create: business name, and optionally a contact name, email address, phone number, lead time and payment terms.
- Purchase orders, receipts, bills, payments, credit notes and the costs you enter against them.
- Any CSV file you upload to the importer, and its contents.
- Anything you write to us in a support email.
A supplier contact is personal data about a real person at your supplier. We hold it only so we can put it on a purchase order and, if you ask us to, email that purchase order to them. We never contact your suppliers for our own purposes.
What we collect from your customers
Nothing. Purser is a buying and accounts-payable app. It has no access to your customer records, your orders, or your storefront, and it collects no personal data about the people who shop with you. We answer this question explicitly because Shopify requires us to, and the honest answer is: none of it.
How we use it
- To run the app you installed: build purchase orders, receive stock, calculate weighted-average cost, and track what you owe.
- To write inventory quantities, unit cost and retail price back to Shopify when you receive stock — which is the whole point of the app.
- To email a purchase order to a supplier, when you ask it to.
- To answer your support emails.
- To keep the app working: error logs, which may incidentally contain a shop domain or an order number.
We do not sell your data. We do not share it with advertisers. We do not use it to train machine-learning models. We do not build a profile of your business to sell to anybody, including your competitors.
Where it is stored, and who else touches it
Purser is operated from the United States, and your data is stored and processed there. We are not established in Europe. If you are in the UK or the European Economic Area, installing Purser means your data is transferred to and processed in the United States.
We use three subprocessors, and only three:
- Shopify — the platform the app runs inside, and the source of the product and inventory data. Shopify also handles all billing.
- Fly.io — hosts the application and its PostgreSQL database, in their Ashburn, Virginia region in the United States.
- Resend — sends purchase-order emails to the suppliers you choose to email. They receive the supplier's email address and the purchase order itself.
When Purser emails a purchase order, it is sent from our domain but the reply-to address is yours, so your supplier's reply reaches you and not us. We do not read or store your correspondence with your suppliers.
Payment information
Purser never sees a card number. Your subscription is charged by Shopify and appears on your Shopify invoice. We are told only which plan you are on, and whether the subscription is active.
How long we keep it
For as long as the app is installed. Your ledger is the reason you installed a ledger, and we are not going to quietly expire it.
When you uninstall Purser, Shopify notifies us and we delete your shop's data. We also honour Shopify's mandatory data-deletion requests. If you want your data deleted sooner, or want written confirmation that it is gone, email us and ask.
Your rights
Depending on where you are, you may have the right to access the personal data we hold, to have it corrected, to have it erased, and to object to or restrict how we process it. Purser implements Shopify's three mandatory compliance webhooks, so a data request or deletion request made through Shopify reaches us and is acted on rather than merely acknowledged.
You can also just email us at support@gopurser.com. That is not a worse route than the formal one; it is usually a faster one.
Cookies and tracking on this website
This marketing website sets no advertising cookies and runs no third-party trackers. The app itself sets only the session cookie Shopify requires to keep you logged in. If we ever add analytics or advertising tags, this section will be updated before they go live, not after.
Changes to this policy
If we change how we handle your data in any way that matters, we will update this page and the date at the top of it. If the change is significant, we will email the shop's contact address rather than hoping you re-read a web page.
Contact
Email support@gopurser.com. A person reads it.
