Safety tips
How to buy and sell safely on Nimmdas
🛒 Tips for buyers
Check the listing carefully
Look closely at the photos, description and price. Too good to be true? Be careful!
Communicate via Nimmdas
Use our messaging system. That way everything stays traceable.
Meet in public
Arrange handovers in public, busy places. Never go alone to a stranger’s home.
No advance payments
Never transfer money before you have seen and checked the item.
Check the seller’s profile
Look at ratings, verification and how long the account has existed.
💰 Tips for sellers
Protect your personal data
Never reveal your IBAN, ID number or passwords in messages.
Prefer cash payment
For a handover in person, cash is the safest. Check the banknotes.
Beware of "shipping-company buyers"
If someone wants to send a shipping company and asks for shipping costs in advance — it’s a scam!
Be suspicious of links
Don’t click on links in messages. Phishing is the most common scam.
⚠️ Recognise warning signs
Report fraud
If you experience a scam attempt, report the listing or the user directly on the platform. For serious cases, contact the police (133) or report it online at bundeskriminalamt.at.
