Yes. Your ISP sees a lot.
What they see:
- Every website you visit (even in incognito)
- When you’re online
- Which apps and services you use
What they can’t see:
With HTTPS, they know you visited a site but not what you did there.
Why it matters:
In many countries, ISPs can sell browsing data. They keep logs that can be handed to authorities or leaked.
Solution:
A VPN encrypts everything. Your ISP sees you’re using a VPN, nothing else.
