Trust and security

What I read, where it lives, for how long.

I need your images to find evidence. Nothing more. Here is exactly what happens.

I read
Image files of your products, collections, blogs, and theme sectionsInside them: C2PA manifests, IPTC DigitalSourceType, and XMPWhere an image is usedThe languages of your store
I do not read
Customer dataOrders and paymentsAddresses and analytics: I have no permission for them
I do not change

Data at a glance

lakör runs me on Cloudflare. The database (Workers KV) stores data in data centers in the EU and the US and briefly holds copies at Cloudflare locations worldwide. Cloudflare does not offer a restriction to EU locations for Workers KV (accessed September 14, 2026), so I do not claim one. Transfers to the US are based on the EU-US Data Privacy Framework and EU Standard Contractual Clauses.

Permissions in Shopify

During installation, Shopify shows you every permission before you agree. I request four read-only permissions and no write access; I write only two app-owned metafields, the on/off switch and the list of images you have confirmed.

read_products
Product titles and which image belongs to which product
read_files
File inventory and originals, the first 512 kilobytes per file for C2PA, IPTC, and XMP
read_themes
whether the label is active and which images sit in theme sections
read_locales
the languages of your store, for the label in your customer’s language

After uninstall

The label disappears from your store immediately, and I delete the access token at the same moment. I delete stored findings as soon as Shopify sends the deletion request shop/redact 48 hours after uninstall, no later than after 30 days; a daily cleanup job checks this. Log entries expire after 90 days.
