Cyber security

Stay safe online

As security is paramount to everything we do, we’ve put together an overview of key warning signs — and how to respond quickly if something doesn’t seem right.

Quick tips to keep you safe:

Be wary of suspicious links

Cybercriminals often hide malicious links in text messages, emails, and social media posts. These links may lead to fake websites that look like real online stores, often promoting too-good-to-be-true deals to lure you in. These sites are run by fraudsters aiming to steal your money, personal information, or login credentials. If something feels off — whether it’s a message, post, or website — trust your instincts and follow NCSC guidance (https://www.ncsc.gov.uk/collection/phishing-scams) on handling suspicious messages.

Unexpected emails

If you get an email asking for payment or personal details that you weren't expecting, it’s likely a scam.

Check the sender's email

Scammers often use fake email addresses that look close to the real thing. Always double-check!

Too good to be true

If an offer seems too good to be true, it probably is.

Urgency

Fraudsters create a sense of urgency, but don’t fall for it – take your time to verify.

Avoid suspicious links and downloads

Never click on links, open attachments, or download files from unknown or untrusted sources. Harmful software often disguises itself as legitimate content.

Watch for spelling and grammar mistakes:

Scam messages can come from anywhere. Typos and awkward phrasing are often red flags that something isn’t right.

Use secure websites

Before entering personal or payment information, check that the website is secure. Look for “https://” and a padlock symbol in the browser’s address bar.

Keep your software up to date

Regularly update your operating system, browser, and antivirus software to stay protected against the latest threats and vulnerabilities.

I received an email from sunday asking me for my contact information

I received an email pretending to be a restaurant where I paid with sunday asking me for information or payment.

If you haven’t requested anything that involves payment from a restaurant (such as a booking, special request, or private event), the email you received is likely not from the restaurant, but from someone impersonating them. Neither sunday nor any restaurant you’ve paid through sunday will never ask you to pay via email, SMS, or request any personal information (email addresses, names, bank and card details, etc.) outside of our App or platform that you access through our QR codes in your favorite restaurants.
