# Kuuko · Less tracking. Fewer ads. No log. Blocking you can test.

Kuuko is an app for iPhone and Mac by SF4L S.R.L. (Bucharest, Romania). Kuuko 1.0 is coming soon to the App Store.

## One app, three tools

- **Blocking: trackers, ads and scams.** Across your apps and browsers. Plain switches for Meta, device makers, fake shops, pop-up ads, social networks, gambling and more.
- **VPN: your VPN, blocking inside.** Add your provider's WireGuard config, for example from Proton VPN. Kuuko runs no VPN servers. [Which VPNs work](https://kuuko.app/vpn/)
- **Aliases: one address per shop.** @kuuko.me aliases, forwarded to your inbox. They live in your vault: no name, no password, no email address to sign in. Your passkey or your 12 words open it.

## What our servers keep about you

No log of your lookups. No access logs.

Your IP address is held in memory only, never written to disk: Kuuko DNS forgets it within about 6 minutes of your last lookup, the app server within an hour. This website counts visits without it. With a vault, we keep only what the features you use need. Details: [privacy notice](https://kuuko.app/privacy/).

## What Kuuko is not

- **Not a VPN company.** Kuuko runs no VPN servers. Bring a provider you trust that offers WireGuard configs, for example Proton VPN. Kuuko keeps blocking inside the tunnel.
- **Not a data company.** Blocking and the VPN need no vault at all. No ads, no analytics, no tracking. We never sell your data, and keep only what the features you use need.
- **Not a black box.** Three independent tests, run by others, show what reaches your browser. Every article in the app and in [Learn](https://kuuko.app/learn/) names its sources. Our goal: anyone could build Kuuko themselves. [We'll publish the how-to here](https://kuuko.app/build/).

## Same phone, different answers

| Without Kuuko | With Kuuko |
| --- | --- |
| The names you look up usually go to your internet provider | Encrypted to Kuuko; no record of who asked for what |
| Trackers load in your apps | Trackers on your block lists get "doesn't exist" |
| One email address, everywhere | One address per shop, leak warnings if you switch them on |
| You take the app's word for it | You test the blocking yourself, in the app and in your browser |

The protection test in the app asks Kuuko DNS about 13 known trackers: with the recommended lists, 12 are blocked; the 13th, Google Tag Manager, is blocked only with Google extras or Stricter protection switched on, because some websites break without it.
