# How to use PromoStar to set up an 18+ gate and in-app browser escape for your bio link

> Link in Bio gives fans an 18+ age gate and an open-in-browser escape from in-app browsers such as Instagram and TikTok, on an onlypromo.link address.

Open **Link in Bio**, leave **18+ age gate** and **Open in browser (in-app escape)** switched on, and publish. Fans then confirm their age before your links appear.

## Steps

1. Click **Link in Bio** in the sidebar. On the **Content** tab, find **Safety & escape**.
2. Keep **18+ age gate** on. Edit **Gate headline** and **Gate message** to change the wording.
3. Keep **Open in browser (in-app escape)** on. Click **Save**.
4. Under **Your links**, add each link. **Behind the 18+ gate** is on by default, and the added link shows an **18+** tag. Turn it off for safe-for-work links such as your Instagram.
5. Click **Publish**, then copy your page address from the top of the page.
6. Switch the preview between **Gate** and **Page** to check both views.

## What a fan sees

Your photo, name, and bio load first, without links. If any link has the **18+** tag, the gate shows your headline and message with an **I’m 18 or older — continue** button. After a fan confirms, your links appear, and that browser remembers it on your domain. Each link points to a short address on your domain that forwards to your real destination.

Inside an in-app browser, a hint shows how to open the page in a full browser. On Android, tapping a link also tries Chrome. On iPhone, the hint says to tap **•••** at the top right and choose **Open in browser**.

<Info>
  On iPhone the fan has to make that tap, because iOS gives the page no reliable way to leave the in-app browser.

## Good to know

* PromoStar assigns the domain for your page address.
* The **Insights** tab shows link clicks, **Top links**, **Sources**, and **App / browser**.

## Where the data comes from

PromoStar's public Link in Bio service serves your page. Each tap on a link stores a click record in PromoStar's database with the fan's IP address, their browser's user-agent string, the referring page, the detected app and device type, and whether they passed the gate. **Insights** shows counts, not IP addresses.
