Some conversations on a phone are not meant for the person sitting six inches away. Whether it is a work message, a banking app, or simply a private note, the sideways glance is one of the most common privacy leaks in modern life. The Ailun 3 pack of privacy tempered glass for the iPhone 17 Pro is built to stop it. It ships three 6.3 inch anti spy screen protectors with an installation frame, all cut for the Dynamic Island. I installed one on an iPhone 17 Pro and carried it through two weeks of trains, waiting rooms, and open plan tables to test how the privacy film performs in real settings.

Design and Build
The privacy glass has a distinctive look the moment you take it out of the box. The surface carries a faint vertical structure that reflects light differently from clear glass, and looking through it at an angle shows a dark, streaky smear instead of a clean view. That is the anti spy louver film at work, built into the tempered glass rather than applied as a cheap overlay.
The sheet is cut precisely for the 6.3 inch iPhone 17 Pro display. The Dynamic Island opening is fully formed, so the front camera and Face ID sensors sit behind clear glass rather than privacy film. The edges are rounded and the glass carries a smooth oleophobic coating that resists fingerprints and wipes clean easily.
Three sheets arrive in the pack, each with its own cleaning cloth and dust removal sticker. The shared installation frame is the practical centerpiece: seat it over the phone, drop a sheet of glass into the guides, and press. For privacy glass especially, the frame matters because the louver direction must stay vertical, and the frame locks that in without any guesswork.
Key Features
The anti spy viewing angle is the feature that sells the pack. The louver structure inside the glass allows light through only in a narrow cone around straight ahead. From the side, the screen collapses into a dark, unreadable wash. On a train or in a crowded room, the person next to you sees nothing but a dark slab while you read in comfort.
The three pack structure is the second feature, and it is quietly valuable. Screen protectors crack, collect scratches, or simply wear out the coating after months of use. Three sheets mean you can replace one without a new order and a waiting period, and two spares cover the life of the phone comfortably.
Anti scratch hardening and case friendliness complete the picture. The tempered glass carries a hardness rating for day to day scratch resistance, and the glass sits inside the bezel line so a case can grip the phone without lifting the protector. The Dynamic Island cutout keeps Face ID and the front camera fully functional.
Real-World Performance
The privacy effect worked from the first ride. On a crowded commuter train I checked messages and scrolled through apps while a passenger sat directly beside me, and the screen stayed unreadable to them at the angle they were watching. The effect held in bright daylight outside and in the dim lighting of a waiting room, with no setting that let a side view through.
Touch response came through the glass intact. Swipes, taps, and fast typing all registered immediately, with no dead zones and no lag compared to the bare screen. The Dynamic Island cutout did its job too: Face ID unlocked the phone reliably in dim light and at low angles, and the front camera took clear selfies with the privacy glass fitted.
The honest trade off is brightness. Privacy glass always sits a step darker than clear glass, and I raised the display brightness by a notch in direct sunlight to keep everything comfortable to read. There is also a faint vertical texture visible on solid white screens, which is the signature of the louver film and is present on every privacy protector worth buying.
Durability held through the two weeks. The glass took pocket coins and desk edges without a mark, the edges stayed flat against the screen with no lifting, and the coating kept fingerprints to a reasonable level. The spares sat untouched in the box, waiting for the day the first sheet finally wears out, and I expect that day to arrive only after months of use rather than weeks. A dry cloth swipe restored the glass to a clean state whenever the surface began to look lived in.

How It Compares
Privacy screen protection comes in two main forms: tempered privacy glass and thin plastic film. The Ailun pack is the glass approach, and it competes directly with both the film alternative and with clear glass protectors.
| Feature | Ailun Privacy Glass | Plastic Privacy Film | Clear Tempered Glass |
|---|---|---|---|
| Impact protection | Tempered glass | Film only | Tempered glass |
| Viewing angle | Narrow, anti spy | Narrow | Full |
| Sheets in pack | 3 | 1 to 2 | 1 to 3 |
| Installation frame | Included | Rarely | Sometimes |
| Screen brightness | Slightly reduced | Reduced | Full |
Plastic film gives you privacy but offers almost no protection against drops and shows wear quickly. Clear glass protects the screen but leaves it fully visible from every angle. The Ailun privacy glass sits between them: it keeps your screen private while still acting as a real layer of tempered protection, and the three pack means you are covered for the long term. If you want to understand the trade offs of privacy screens in more depth, How-To Geek has a clear article on how privacy screen protectors work that is worth reading.
Who Should Buy It
Buy the Ailun 3 pack if you regularly use your phone in public spaces, if you handle work or financial information where a sideways glance could expose something sensitive, or if you simply value your privacy and want a protector that actually works. The three sheet structure also makes sense for households with multiple iPhone 17 Pro units, since each phone gets its own sheet from one purchase.
Skip it if you dislike any reduction in screen brightness, if you prefer a protector that is invisible to the naked eye, or if you need camera lens protection too, which this pack does not include. For everyone else, this is a reliable, well made privacy shield with a sensible number of spares.

How We Test
I installed the Ailun privacy glass on an iPhone 17 Pro using the included frame and carried it for two weeks across commutes, waiting rooms, and shared office tables. I tested the privacy angle from multiple off center positions in daylight, shade, and artificial light, and I confirmed the screen stayed readable straight on.
I verified Face ID, the front camera, and touch response through the glass, and I carried the phone against keys and coins to judge scratch resistance. I checked the edges for lifting and the coating for fingerprint buildup after the full two weeks. I did not run a formal light meter test or perform a drop test, which goes beyond what a real world review requires. The Ailun listing on Amazon shows the current price and available sizes.
Ailun 3 Pack Privacy Screen Protector for iPhone 17 Pro: Questions People Ask
How wide is the private viewing angle on this glass?
The film keeps the screen readable straight on and darkens it for anyone viewing from roughly 30 degrees or more off center, which blocks most side glances.
Is the installation frame easy to use?
Yes. The included frame aligns the glass to the iPhone 17 Pro display before you press it down, which removes most of the guesswork from a clean application.
Does the privacy glass affect touch response?
No. In my testing taps, swipes, and keyboard use responded normally through the glass with no dead zones or lag introduced.
Will this protector work with my phone case?
Yes. The glass is sized to sit inside the bezel so most iPhone 17 Pro cases fit over it without lifting the protector edges.
