In short: INCY is a free client app for connecting over modern protocols (VLESS, Hysteria2, Shadowsocks and others). It has no servers of its own — to make INCY work you add a subscription from a service: by link, by QR code, or with a single button. Tainet uses the third option: when you sign up, the subscription is added to INCY with a button in the connection instructions, and the whole path from registration to a working connection takes about 30 seconds. Below: setup on every platform, fixes for the common problems, and a comparison with Happ.
The practical steps are below; if you'd rather skip the setup, Tainet connects in a couple of minutes - through the Telegram bot or in your account on this site.
What INCY is, and why the screen is empty after installing
The most common beginner mistake is installing INCY and expecting it to work on its own. INCY is a client, a shell: it knows how to establish a secure connection, but the servers come from a service subscription. So the order is always the same: app + subscription.
The client’s strong points: it runs on iOS, Android, Windows, macOS, Linux, Android TV and — rare among clients — on Apple TV; it sends the subscription from your phone to your TV in one tap; it integrates deeply with the system (widgets, Live Activity, control through Siri and Google Assistant); and it lets you pick which apps go through the connection. All of that in a minimalist interface with one big button.
A Tainet subscription — with a free first week — is set up in the Telegram bot or in your personal account on this site, and lands in INCY with a button from the connection instructions.
Where to download it: official sources only
An important warning: a lot of unofficial sites have grown up around INCY, selling “keys” and handing out their own builds of the app. Downloading modified builds from third-party sites is dangerous — all of your traffic goes through the client. The official sources are these:
- iPhone, iPad, Apple TV — the App Store; the app is available in a Russian account, no region change needed
- Android and Android TV — Google Play (check the publisher: llc.itdev.incy) or the APK from the developers’ page on GitHub (INCY-DEV)
- Windows, macOS, Linux — builds from the developers’ GitHub Releases or from the official site incy.cc
If a site offers to “sell you a key for INCY”, those are resellers: keys are not bought separately, your service issues them together with the subscription.
Setup on iPhone and iPad
- Install INCY from the App Store.
- Add the subscription. With Tainet it takes a button: in the connection instructions (in the bot or your personal account on this site) tap the add button for INCY — the app opens with the subscription already loaded. Manually: copy the subscription link → tap ”+” in INCY → “Add subscription” / “Import from URL” → paste.
- Allow the VPN profile to be installed — the system asks once.
- Pick a server and press the connect button.
Setup on Android and Android TV
- Install INCY from Google Play.
- Add the subscription: with the button from the Tainet instructions (bot / personal account), or manually — ”+” → “Add subscription” → paste the link or scan the QR code.
- Allow the VPN connection when the system asks, pick a server, connect.
For a TV, INCY has its own path: if the app is on your phone as well, the subscription is sent from phone to TV in one tap, with nothing to type or scan. The classic QR route works too: open the subscription QR on your phone and scan it off the screen. Other ways to connect a TV are in the TV guide.
Setup on Windows and macOS
- Download the build for your system from the developers’ GitHub or incy.cc.
- Launch the app and add the subscription by link (the ”+” button → import from clipboard).
- Pick a server and switch the connection on. If you have proxy extensions in your browser, turn them off: they conflict with the client.
INCY or Happ: which to pick
A frequent question, and an honest answer: both clients work with the same subscriptions and the same protocols; the difference is in character. INCY is on Apple TV, is more deeply wired into the system (widgets, Siri/Google Assistant, one-tap subscription hand-off to a TV) and is more minimalist; Happ has been around longer and feels familiar to more people. Practical advice: the subscription is one and the same — try both and keep whichever suits you personally. Our guides: Happ, a comparison of all the clients.
Moving a subscription from Happ to INCY takes a minute: copy the subscription link (in the Tainet bot or account — the “My subscription” button, it is the very same link) and add it to INCY following the instructions above. Nothing has to be re-created, and both installs can live side by side.
INCY isn’t working: the common problems
Connected, but no internet. Switch to another server in the subscription list — Tainet has several, and switching takes seconds. Then refresh the subscription: pull the server list down (pull-to-refresh) and the client will fetch the current configurations.
Error 403 or “subscription expired”. The key is stale: refresh the subscription with the same gesture, and if the term really has run out, renew it in the bot or your personal account on this site and refresh the list.
The subscription won’t add. Turn off other VPN clients and extensions on the device and try adding it again. Check that the link was copied in full.
Doesn’t connect on mobile data, but works on Wi-Fi. Change the server and the protocol in the profile settings — a Tainet subscription carries configurations for different network conditions.
Stopped working after a system update. Reinstall the app and add the subscription again — a minute’s work, the link is unchanged.
Still stuck — write to support: at Tainet real people answer, and they will help with your specific device.
Tainet - no config files, no manual fiddling: the app link and a guide for your device show up the moment you sign up. Sign up through the Telegram bot or in your account on this site, from $0.10 a day.
