You’re not the only one.
Most people here aren’t leaving anyone. They’re looking for the part of themselves that got put away.
“Fourteen years in. Loved, but not looked at.”
Sage, 41
“We're good parents. We stopped being anything else.”
Atlas, 44
“Separated in every way except the paperwork.”

“Nothing's wrong at home. Something's missing in me.”

Illustrative. ALTER never shows real members on this page.
Most dating apps assume you're single. ALTER assumes you're not. It assumes you have a life you're not leaving, and a part of yourself you're not ready to give up either. So it keeps the two apart: blurred faces, borrowed names, and messages that don't last the night.
Nobody finds out. Not by accident, not on purpose.
Your partner won't find it.
ALTER sits behind your PIN or fingerprint and locks itself the moment you switch apps.
Your friends won't recognise you.
Every photo starts blurred. You choose who sees the clear version, and for how long. Your name is an alias.
Your chats won't outlive the night.
End-to-end encrypted, screenshot-blocked, and gone within the hour.
Nobody sees you looking.
Invisible Mode takes you out of everyone's search while you browse. Look around without being looked at.
Try it
Grant Atlas an hour.
This is the real approval sheet from the app. Your photo starts out of focus. Someone asks. You choose how long they get. When the time runs out, you’re blurred again without lifting a finger.

The conversation that never happened.
End-to-end encrypted, and gone within the hour. Every message carries its own timer. When it runs out, there’s nothing left to find.

Yes. ALTER is built for people who are married or in a relationship, and for singles who are open to dating them. Everyone knows the situation going in.
Not by browsing: you appear under an alias, blurred, and Invisible Mode keeps you out of search while you look around. Not on your phone: the app sits behind your PIN or fingerprint and locks the moment you switch away.
No. They see your alias and a blurred photo. The clear version is shown only to people you approve, for a period you choose, and it blurs again when the time runs out.
They're end-to-end encrypted, can't be screenshotted, and vanish within an hour. When the timer runs out there's nothing left to find.
Every profile passes a live selfie check and a human review before it appears. ALTER doesn't run bots or paid profiles, and only verified members can message anyone.
Free to download. Plans for messaging are offered inside the app.
Using a dating app isn't a crime anywhere we operate. Whether a relationship outside your marriage has legal consequences depends on where you live, so know your local law.
Yes. Request deletion any time from Settings and your profile, photos, matches and messages are removed. You can ask us to email you a copy of your data first.
