Privacy in online shopping

Privacy in online shopping: simple rules for buyers and shops

Clear and practical: data minimisation, account options, consent, cookies and understandable notices for online shopping — without legal advice.

Data minimisation as a basic rule

Data minimisation means collecting only the information needed for the task. For many orders, name, shipping address and one contact method are enough. Fields such as birthdate or occupation are usually optional and should not be mandatory. Forms should be designed to keep required fields minimal and mark optional fields clearly. Technically, separating sensitive data — for example keeping payment details in specialised systems — reduces risk compared with storing everything in a single database.

  • Limit required fields to essentials
  • Mark optional fields clearly
  • Store sensitive data separately and securely

Accounts, guest checkout and fewer stored: Guest checkout lowers barriers for first-time buyers and reduces stored customer data. Shops should offer both options: an account for repeat buyers and a guest flow for one-off purchases. Account registration should request only basic information and keep extra profile details optional. When creating an account, let users choose which extra features to enable, such as wish lists or marketing emails.

  • Offer guest checkout as an option
  • Keep account registration minimal
  • Make extra features opt-in

Consent, cookies and clear notices: Consent must be voluntary and informed. That means plain language, clear buttons and separate choices for different purposes (for example essential cookies vs tracking). Cookie banners should offer simple options like «essential cookies only» and «allow personalization». Detailed information about cookies, processing purposes and retention should be easy to find, for example in a privacy notice that explains in everyday language what data is used and why.

  • Provide separate consent choices by purpose
  • Offer a clear «essential cookies only» option
  • Keep the privacy notice simple and accessible

Personalisation without overreach: Personalised offers can improve relevance but must respect privacy. Shops can implement recommendations so data is processed locally or pseudonymised. Another approach is to ask users to opt in to personalised content. Transparency is key: explain which data is used for recommendations and how long it is retained.

  • Make personalised offers opt-in
  • Process data locally or pseudonymously where possible
  • State retention periods and purposes clearly

Discover and shop

Shop for products simply and safely online

At OpenDeal, you can find products for many everyday needs and review the key information in one place. Clear images, visible prices and concise details help you compare an offer before you make a decision. Open the product details when you want more information about condition, stock, delivery or pickup. Compare suitable offers with your needs and budget, then review your cart before you complete the purchase.

Everything clear at a glance

Each product page brings together the price, condition, availability and other useful details for your decision. Read the details carefully and check which parts, options or services are included with the offer. Compare similar products with your needs, budget and the way you expect to use them. This makes it easier to choose an offer that is suitable for you.

Images help you choose

Review the product images carefully and look at the shape, colour, surface and other visible details. Several views can make the size, condition and important features easier to understand before you decide. Then read the description and check whether the written details match what you can see. This gives you a clearer picture of the product before purchase.

Your favourite in the cart

If you like a product, add it to your cart and review the price and quantity there. You can change the quantity, remove an item or continue shopping before you move to checkout. Before the next step, check the selected variant, condition and the available shipping or pickup method. Continue to checkout only when the full selection is correct for you.

Buying is this easy

Choose a product, review the information and add the item to your cart when it suits you. At checkout, enter the required details and review the full order before you confirm anything. Check the price, quantity, address and the available shipping or pickup option one final time. Confirm the purchase only when the details and total cost are correct.

Shipping or pickup

Each offer explains how the product will reach you and which conditions apply to the handover. Many products can be shipped, while other offers may be available for pickup at a stated location. Before you buy, review the location, possible costs and any important notes from the seller. This helps you choose the option that works best for your schedule and location.

Shop with confidence

OpenDeal presents offers clearly so that you can compare products and understand the key information before buying. Fixed prices support your planning, while images and concise descriptions make different products easier to assess. Take enough time and complete the purchase only when the offer matches your expectations. This keeps the process clear from the first search through to the final order.

Browse at your own pace and discover useful products for daily life, your home or a suitable gift. Open the offers that interest you and review the price, condition, stock and handover information. Before you buy, check the important details once more and give yourself enough time to decide. This helps you make a careful choice and understand what happens next.
