Only what each staff member needs to do their job. On Shopify we use the official access Shopify provides, such as a staff or collaborator account or an approved app connection, and we never ask for your personal password.
On Etsy you choose how we work. By default we don't need any access: your staff work from the order, listing and payment files you download from Etsy and the review and message emails you forward, and you post the drafts you like.
If you'd rather we make approved changes inside your shop, you can choose hands-on help in writing. Etsy discourages sharing logins and its terms restrict bots and automated tools, so this choice carries some risk to your shop, and you carry that risk. We act in your shop only on tasks you've said yes to, and where Etsy allows it we recommend adding us as a separate team member instead of sharing your own login.
You can remove our access at any time from your store settings, and if you cancel, we stop working on your store at the end of the month you've paid for, or sooner if you ask. We don't sell your data. Details are in our privacy policy.
