AdGuard Temp Mail’s addresses are temporary and aren’t stored long by design:
Emails are automatically deleted 24 hours after you receive them.
A temporary mailbox is deleted after 7 days of inactivity. But if you keep the page open or come back in a couple of days, it won’t disappear.
AdGuard Temp Mail is currently in beta stage. Here’s what we’re planning to add in the future:
Zero-access encryption
TLS support on the SMTP server side
Image proxying
Security checks for links
AdGuard is a Russian company that sold ad analytics - they collected user data for ads. Then, they suddenly renamed and started all those “free and cool adblocking services!” like their DNS. Reddit loves them, and downvotes anybody that suggests actually trustworthy alternatives like NextDNS. In fact, AdGuard employees had official Reddit accounts where they answered basic questions and dodged more detailed ones, but sometimes they also used astroturfing fake accounts.
I would not use their stuff, even if it’s a temp email.
Do you still the have the link to news article where it was reported?
Earlier I was using Pi-Hole on my network then switched to AdGuard Home (not same as AdGuard DNS) as it is an open source product with in-built DOH support (yes, I can setup Pi-Hole to do the same, but that’s an extra manual configuration) and Privacy Guide seems to recommend it over Pi-hole. After reading your post, I tried to lookup more about it. Nothing on Wiki. Closest thing is this. If the allegations are true then I need to switch back to Pi-Hole.
That comment is just speculation… In fact many of the Adguard employees are from Ukraine and other not so pro Russian countries. I remember their support being almost stale when the war started.
