Sidrenko, a Shopify app by Klikoteka. Last updated 22 September 2026.

What Sidrenko stores

Your shop domain and the access token Shopify issues at install.
Product and variant identifiers, their prices, and the collections or product category they belong to.
A daily record of each product's price, kept for 100 days plus the reference days the Croatian decision sets. This record is what backs the lowest price in 30 days and the anchor price.
Your app settings: reference days, category rules, and the outlet details that go into the price list file name.

No customer data. The app does not request the read_customers or read_orders scopes, so it never receives names, addresses, e-mail addresses or order contents.
No payment details. Billing runs entirely through Shopify App Pricing; we never see a card.

Croatian law (NN 101/2026) requires a merchant to show an anchor price and the lowest price in the previous 30 days, and to publish a daily price list. Shopify does not keep a history of displayed prices, so the app has to record one. Without that record the merchant cannot substantiate either figure.

Nobody. The data is not sold, rented or passed to third parties for their own purposes. The generated price list is published on your own domain because the law requires you to publish it.

Price history is trimmed to 100 days on a rolling basis, except the reference days the decision names, which are kept because the anchor price is read from them.
When you uninstall the app, the session is deleted immediately. Price history is kept until Shopify sends the shop/redact request, which arrives 48 hours after uninstall, and is then deleted in full. It is not deleted at uninstall because a merchant who removes the app for a week and reinstalls it would otherwise lose the record for exactly the period someone may ask about.

Uninstalling the app stops all processing. To have the data removed sooner, or to ask what is held, write to info@klikoteka.hr.
