Subscriptions
Users get one link, https://your-domain/sub/<token>. Their app downloads the host list from it. The same link also serves other formats (Clash, sing-box, JSON) depending on the client.

Subscription page
When a user opens the link in a browser they see a branded page with their account, app setup per platform (iOS, Android, Windows, macOS, Linux), the link, a QR code and, if enabled, their devices.
In Settings → Sub → Web page you can change the title, logo, support link, accent colour and theme, the languages offered (English, Türkçe, Türkmençe, Русский, فارسی, 中文), which sections appear, the texts per language, the app list and custom CSS. Preview shows the result as a real user.
Look, apps and JSON

Look picks the card style (Soft, Liquid glass, Clay), the theme and the accent colour of the page. Apps is the list of client apps per platform with their import links: reorder, edit and add apps.

The JSON tab controls the JSON subscription: which clients get it, sites that go direct (not through the VPN), ad blocking, and the automatic (balancer) config.

Link and domain
Domain settings sets the address, path and last part of every subscription link (for example https://sub.example.com/sub/<token>). Links already handed out keep working. Resellers can have their own domain.

Texts shown in apps
The Sub page tab holds the title and announcement apps show. Per state you can set different texts: expired, disabled, limited and near expiry. Placeholders: {username}, {used}, {limit}, {remaining}, {expiretime}, {days}, {token}.
Extra configs
External Configs adds extra links to every link-based subscription and sets the order of links and protocols.

Limits
- Update interval: how often apps are told to refresh, in hours.
- Rate limit: the shortest time between two fetches of one user. More rules per IP and per user are in Subscription statistics.
- Device (HWID) limit: a user can fetch the subscription from only a set number of devices. Over the limit, the app gets an empty list and a message.
