Technology class is a public Telegram group — anyone can join without invitation. Your phone number is never visible to other members unless you've made it public in your Telegram privacy settings. You can leave at any time with a single tap.

No. Telegram never notifies your contacts when you join or leave a group. Other members inside Technology class can see your username only if you post — your membership is not visible to anyone outside the group.

Technology class is a Telegram group for anyone interested in technology and tutorials. Members can expect regular discussions on news and apps, along with security to research.

We verify every listing is publicly accessible, has a minimum member count, and exclude groups Telegram has marked as harmful. If you've joined Technology class and noticed something suspicious — a review on this page helps others stay safe.
