Privacy policy for Glass OS
Last updated: 1 October 2026
Glass OS is a home screen for Android keyboard phones, published by illuminati Apps, United Kingdom. This policy covers the app itself. It is short because the app does very little with your information, and everything in it can be checked against the permission list in Android's settings.
The short version
There is no account, no sign-in and no analytics of our own. Nothing you type into Glass OS, and nothing it reads from your phone, is sent to us. We do not have a server that could receive it. Two things can leave your phone by themselves: a weather lookup, and basic diagnostics from Google's ML Kit if you use your own photo as a wallpaper. The only thing that leaves at your instruction is a backup file whose location you choose.
What stays on your phone
All of it, unless a section below says otherwise.
- Your notes, to-dos and events, and anything you type into Search, are stored in a database inside the app's own private storage.
- Your contacts. Glass OS reads your contacts so that typing a name can call or message that person. It reads them when you type and does not copy them anywhere.
- Your calendars. Glass OS reads the calendars already on your phone to show your events, and writes events back to them when you create one.
- Your notifications and conversations. The Hub is fed by Android's notification access. Notifications are held in the app's own storage so you can read and search them, and are deleted on the schedule you set in Settings. Messages in a conversation, pictures that arrive in notifications and the senders' profile pictures are also saved in the app's own storage so a conversation can be shown in full, and are deleted after 30 days. You can clear them sooner in the Hub's settings. Notifications are also counted to show the number badges on your app icons; the counts are not stored.
- Your wallpaper and photos. If you choose one of your own photos as a wallpaper or as an app's icon, Glass OS keeps a copy of it, and for a wallpaper the cut-out it makes of the subject, in its own storage. The photo is chosen through Android's photo picker, so Glass OS only ever sees the one picture you pick.
- Your settings and Home Screen layout.
None of this is transmitted, sold, shared or used for advertising. There is no advertising in the app.
What can leave your phone by itself
The weather. If the weather is showing, Glass OS sends an approximate latitude and longitude to the Open-Meteo API (open-meteo.com) to get a forecast back. No account, no identifier and nothing about you is sent with it. To get that position the app asks for approximate location only, never precise location. It takes one coarse fix, uses it, and stores the resulting town name and coordinates on your phone.
Photo cut-outs. When you use your own photo as a wallpaper, Glass OS uses Google's ML Kit subject segmentation to find the subject so the clock can sit behind it. The photo is processed on your phone and is not sent anywhere. ML Kit, which is delivered through Google Play services, does send Google basic diagnostics: the device model and Android version, the app's name and version, performance figures, the image size and format, and a per-installation identifier that is not meant to identify you. Google uses this for diagnostics and usage analytics and states that it does not pass it to third parties. See Google's ML Kit data disclosure. If you only use the built-in wallpapers, ML Kit is never used.
Handing things to the apps you already use
When you write a message or an email, place a call, set an alarm or a timer, search the web or ask your assistant, Glass OS hands what you typed to the app you already use for that and steps out of the way. It has no account of its own for any of them, it never asks you for a password to any of them, and nothing passes through us on the way. What happens next is between you and that app, under that app's own privacy policy.
The thing that leaves only if you ask it to
Backup. The backup is a single file, encrypted with a passphrase you choose, written to a location you pick. It holds your notes, to-dos and settings, and any pictures you chose for your wallpaper or app icons. We have no copy and, without your passphrase, no way to read one.
The accessibility service
One optional feature, Swipe Down For Notifications, works through an Android accessibility service. You are shown what it does and asked to agree before it can be switched on.
It reads nothing. The service is declared with no accessibility event types at all and without permission to retrieve window content, so Android never sends it anything about what is on your screen, in this app or any other, and it is not able to ask. It performs exactly two actions: opening the notification shade and opening the quick settings panel. No data is collected, stored or shared through it, and nothing it does leaves your phone. You can turn it off at any time in Android's Accessibility settings.
Permissions, and why each one is there
| Permission | Why |
|---|---|
| Contacts | So typing a name can reach that person. Read when you type, never copied. |
| Calendar (read and write) | To show your events and to save events you create. |
| Notification access | To show your notifications and conversations in the Hub, to show number badges on app icons, and to control music that is playing. |
| Approximate location | One coarse fix for the weather. |
| Internet | The weather lookup, and ML Kit's diagnostics described above. |
| Network state | To show the Wi-Fi and mobile signal icons on the Home Screen. It does not see what you do online. |
| Set alarm | To hand an alarm you typed to your own clock app. |
| Set wallpaper | To set your lock screen to the same picture as your Glass OS Home Screen, so the two match. Glass OS draws its own Home Screen wallpaper. |
| Biometric | To put private notes behind your fingerprint. Handled by Android; the app never sees a fingerprint. |
| Request to delete apps | So you can uninstall an app from the Home Screen. Android always asks you to confirm. |
| Run at start-up, foreground service, wake lock | To run your daily backup, if you turn daily backups on. |
| Accessibility service (optional) | Swipe Down For Notifications. See above. |
Glass OS does not ask for your text messages, your call log, your microphone, your camera, your files, your photo library, or the full list of apps on your phone. Icon packs are found by asking Android only for apps that declare themselves as icon packs.
This website
glass-os.app uses Vercel Web Analytics to count visits. It sets no cookies and does not identify you. It records the page you visited, the site that sent you, and your rough location, browser and device type, and only ever shows us totals. Buying happens on Gumroad, which has its own privacy policy.
Children
The app is not directed at children and collects nothing from anyone, including children.
Changes
If this policy changes, the date at the top changes with it, and anything that materially affects what leaves your phone will be called out in the release notes.
