Main rule: share as little as possible

Only give the information a shop needs to complete your order. For delivery that usually means name, address and contact. Other details such as birthdate or interests are often optional. Use a separate email for subscriptions if you want to avoid promotional messages in your regular inbox. Check which fields are labelled as mandatory. When in doubt, ask customer support which data are strictly required.

Fill only mandatory fields
Use separate email for newsletters
Skip unnecessary profile fields

Account or guest checkout: An account speeds up repeat purchases and stores receipts. It also makes returns and order tracking easier. The downside is ongoing data storage and possible profiling. Guest checkout requires fewer long‑term details and reduces stored data. It is convenient for one‑off buys but can make tracking orders harder. Decide based on how often you shop and how much convenience versus privacy you want.

Account: convenient, more data stored
Guest: fewer data, fewer features
Review account settings regularly

Consent and personalization explained: Shops often ask you to consent to newsletters, personalized offers or tracking before checkout. These options are usually optional; you can uncheck marketing consents without blocking the purchase. Personalization uses past orders and browsing behaviour to suggest items. It can be useful but reduces privacy. If you prefer generic offers, turn off personalization options or remove interest tags from your profile.

You can limit personalization anytime
Keep records of consents or use unsubscribe links

Cookies, notices and your rights: Cookie banners explain tools that track behaviour or store settings. Necessary cookies often keep your cart and checkout working. Analytics and advertising cookies are optional. Use the cookie manager to select only the categories you accept. Read the privacy and cookie notices to see how long data are stored. You have rights to access data and to withdraw certain processing; contact details for this are typically listed in the privacy policy.
