2. What this is about

The app helps Shopify merchants show the unit price (§ 4 German Price Indication Ordinance) and, for price reductions, the lowest price of the last 30 days (§ 11 of that ordinance). It is installed through Shopify, runs in the merchant’s Shopify admin and works with the store’s products and prices, not with customers, orders or payments.

3. Data processed

Store access. On installation, Shopify transmits the store address (myshopify domain) and an access token that lets the app access the merchant’s products on their behalf. Where Shopify provides it at sign-in, the app also stores the ID, first and last name, email address and locale of the signed-in staff member.

Product data. The app reads products through Shopify’s API. Only for stores with more than 1,000 products does it keep a copy of the product data (ID, title, handle, vendor, product type, tags, status, image URL and, per variant, title, SKU, barcode, price, compare-at price and unit price details) in its database, so that its pages load quickly.

Price history. For the 30-day lowest price, the app stores, from first use, each variant’s price and compare-at price with the time of every change (with the product and variant ID), as well as lowest prices the merchant enters and the app’s settings.

What the app writes to the store. At the merchant’s request it sets Shopify’s unit price field on variants and stores the lowest price of each discounted variant in a metafield (preisklar.tiefstpreis), which the app’s block shows on the product page.

Subscription. Whether a store has already used the free trial is stored as a non-reversible key (HMAC) of the store address with the date.

Server logs. When pages are requested, the server processes the IP address, time, requested URL and user agent.

4. Purposes and legal bases

Providing the app to the merchant: Art. 6(1)(b) GDPR (contract). Trial note and server logs: Art. 6(1)(f) GDPR (preventing abuse, secure operation). Emails to us: Art. 6(1)(b) or (f) GDPR.

5. Recipients

• Shopify (Shopify International Limited, Victoria Buildings, 1–2 Haddington Road, Dublin 4, Ireland): the platform through which the app is installed, billed and used.

The app and its data stay in the EU. Only emails to us may also be processed by Google in the USA; Google LLC is certified under the EU-U.S. Data Privacy Framework (EU Commission adequacy decision, Art. 45 GDPR).

6. Retention

• On uninstall, the app immediately deletes the access tokens and the copy of the product data.
• Price history and lowest prices entered: while the app is installed, at most until deletion after uninstall.
• Unit price fields and metafields remain in the store after uninstall and can be changed or deleted there.
• 48 hours after uninstall, Shopify requests deletion of all store data; the app then deletes everything for that store except the trial note.
• Trial note: 180 days, also after uninstall.
• Server logs: 7 days.
• Backups: deleted data disappears when the backup expires, at the latest after 12 months.

7. Your rights

An email to info@syncventura.de is sufficient. You may also lodge a complaint with a supervisory authority (Art. 77 GDPR); the competent authority is the Data Protection Commissioner of Lower Saxony, Prinzenstraße 5, 30159 Hannover, Germany.
