Consent is the feature
Nobody gets surprised who didn't sign up for it. Every ring starts with a yes.
Permission-first ringtones
Hijack your friends' ringtones. With their blessing.
Pick the exact sound that plays when you call someone — your best mate, your partner, even your mum — the second they say yes. A tiny, consensual surprise that turns every call into an inside joke.

How it works
Three taps. One golden rule:
they say yes first.
-
01
Add someone
A friend, a partner, a parent — anyone with a phone and a sense of humour.
-
02
They give the nod
They tap Allow. No yes, no shenanigans — that's the whole deal, and it's the whole point.
-
03
Pick their tune
Choose the sound that plays when you ring them. Cheesy, chaotic, or weirdly sweet — your call.
Small. Consensual. Extremely satisfying.
Reversible in a tap
Change it, mute it, or pull the plug whenever the joke runs its course.
The good kind of petty
A three-second bit that lands every single time they see your name light up.
Fair questions, straight answers.
Do they actually have to agree?
Always. Zimzam does nothing until they tap Allow — and they can pull that permission back any time, no explanation needed.
Is it just for friends?
Nope. Partners, family, your group chat — anyone who says yes. It runs on permission, not relationship status.
What do you do with my data?
As little as possible — just enough for your account and connections to work. We don't sell it. The full breakdown lives in our Privacy Policy.
Can I delete everything?
Anytime, no guilt-trip. Wipe your account and data from the Delete Account page or from inside the app.
