## What is Private Browser?

Priver is a private browser that automatically locks and protects your browsing history and bookmarks.

• On the home screen, it appears with a calculator-style icon and name, and can be used as a regular calculator at launch.

• When you enter your passcode, the app switches to browser mode, allowing secure and private internet browsing with its built-in browser. Your history and bookmarks are stored only within the app and are never accessible to other apps or devices.

• When the screen is turned off or you return to the home screen, browser mode automatically closes and reverts to calculator mode, keeping your privacy safe even after use.

• No account registration or personal information is required — you can start using it right away.

Note:
On first launch, a tutorial explains how to set and enter your passcode. If you use multiple iOS devices, please complete the tutorial on each device.

### 1/5 — app glitches deleted all of my tabs

*2026-02-14, version 3.10*

if you need to delete the app because it’s glitching don’t expect it to keep your bookmarks. they’ll disappear.

### 1/5 — New update. Now ads??

*2025-12-23, version 3.10*

Newest update brought ads. Now we have to endure a 30 second ad every few minutes. Thanksgreat downgrade I mean update.

### 1/5 — Deleting due to pop up ads

*2025-11-09, version 3.9*

Have had and used this browser for a few years now and it was mostly great. Nov 2025 brought an update and with that update now there are pop ads that you can’t bypass. Each lasting about 3 minutes.  They come on at least once every 5 minutes. This app is now useless and am deleting it.

### 1/5 — New update ruined it

*2025-10-04, version 3.6*

Latest update made it so you’re now forced to stop everything and watch an ad every 3 minutes. The aggressive ad placements on the top and bottom of the screen from before weren’t good enough apparently. You ruined this app completely with this update, I cannot comprehend what went on through your 8 inch thick skulls that you’d think this is a good idea. Your greed and ego is just that massive? Don’t bother with this app guys just use private mode on safari.

### 1/5 — Fell off

*2025-10-04, version 3.6*

They added ads that pop out at you in the middle of browsing. Not worth keeping anymore.

### 1/5 — Did you know

*2024-08-20, version 3.4*

You know there’s a private browser on safari right? 😭

### 4/5 — The Almost perfect 2 in 1 App

*2024-08-11, version 3.4*

Only wished that the ui looks a bit better and that all the ads are to be removed but besides those two complaints, everything else works great and is amazingly well executed in other aspects.  

9/10

### 5/5 — Great

*2024-07-26, version 3.4*

Perfect for when the boys take ur phone and go through ur search history

### 5/5 — One tiny problem

*2024-07-07, version 3.4*

It’s a good app for keeping things hidden but there is one problem, whenever I try to access any kind of website I get the screen that says “No Service” even with full bars and connected to Wi-Fi

### 1/5 — Virus

*2024-07-06, version 3.4*

…so I was just looking up a game I play and it said a few days later 27 viruses detected and I had to get another app to help with that I personally don’t recommend unless you want a virus
