Dayglass – Privacy Policy
App: Dayglass (com.dayglass)
Developer: Hitesh Patel
Effective Date: October 22, 2026
This Privacy Policy explains how the Dayglass app handles your information. Dayglass has no internet access: it does not request Android’s Internet permission, so it cannot send anything off your device. Your wallpaper settings and, if you allow Usage access, your screen time are processed and stored only on your device. There is no account, no server, no analytics, no crash reporting and no ads.
1. Introduction
Hitesh Patel (“we”, “our”, or “us”) built the Dayglass app (the “App”) as a free Android application. By using the App, you agree to the terms described in this Privacy Policy. If you disagree with any part of this policy, please discontinue use of the App.
2. About the App
Dayglass sets wallpapers for your lock screen and home screen that show your day, month and year passing, such as a dot calendar, a day bar or a race track, and keeps them up to date through the day. If you allow it, it can also show your screen time on them. The App does not require an account or login, and it has no server.
The App does not:
- Connect to the internet (it does not have the Internet permission)
- Ask for your name, email address or phone number
- Access your contacts, messages, photos, camera, microphone or location
- Read what you do inside other apps, or their content
- Use analytics, crash reporting or advertising services
- Sell your data or share it with anyone
3. Information Stored on Your Device
3.1 Your Settings
The wallpapers you choose and their settings (for example, the style, colours, which screen they go on and the hour your day starts) are stored on your device and used only to draw your wallpapers. The App also keeps the wallpaper images it draws in its own private storage.
3.2 Screen Time (Optional, Usage Access)
Dayglass can show your screen time on your wallpapers and in the App. This is off until you turn it on: the App explains it first, and you then allow Dayglass in Android’s Settings → Usage access. Everything else in the App works without it.
With Usage access, Dayglass reads Android’s own usage records, on your device, to work out for each day:
- Your total screen time, and the time spent in social apps
- How many times you unlocked your phone, and when you first unlocked it
- For each app you used: how long it was open and how many times you opened it
- When your screen was on, and which apps were used in each of those stretches
Android’s usage records contain only which app was in use and when. They do not contain anything you see, type or do inside an app.
To name the apps in your usage list, the App looks up the names of apps that appear in your launcher. It does not list or read any other installed apps.
These daily summaries are saved in the App’s private storage on your device and kept for up to 400 days, so the App can show your screen time over time. Older days are deleted automatically.
3.3 Android Device Backup
If you have turned on Android’s backup to your Google Account (Settings → Google → Backup), Android may include the App’s data (your settings and the screen-time summaries in Section 3.2) in that backup, so it can be restored on a new phone. That backup is made and stored by Google under your Google Account, not sent to us, and you control it in your Google Account and Android settings.
4. Permissions We Use
| Permission | Why |
|---|---|
Set wallpaper (SET_WALLPAPER) | Sets the wallpapers you choose on your lock screen and home screen. |
Usage access (PACKAGE_USAGE_STATS) | Optional. Reads your screen time on your device, as described in Section 3.2. You turn it on yourself in Android settings. |
Run at startup (RECEIVE_BOOT_COMPLETED) | Keeps your wallpapers updating after your phone restarts. |
Background work (WAKE_LOCK, FOREGROUND_SERVICE, ACCESS_NETWORK_STATE, POST_NOTIFICATIONS) | Requested by Android’s background task library (WorkManager), which the App uses to update your wallpapers through the day. The App has no internet access and does not use these to send anything. |
You can turn off Usage access at any time in Android settings (Settings → Apps → Special app access → Usage access → Dayglass).
5. Third-Party Services
None. Dayglass contains no analytics, crash reporting, advertising or other third-party services that collect data, and it cannot connect to the internet.
6. Data Retention
- Your settings and wallpaper images stay on your device until you change them, clear the App’s data, or uninstall the App.
- Screen-time summaries (Section 3.2) are kept on your device for up to 400 days, then deleted automatically. They are also deleted when you clear the App’s data or uninstall the App.
- Android device backups (Section 3.3) are kept by Google under your Google Account settings.
We do not hold any of your data, so there is nothing for us to retain.
7. Children’s Privacy
The App is not directed at children under the age of 13. It does not collect personal information from anyone, children included, because nothing leaves the device.
8. Data Security
Your data never leaves your device through the App, so its security depends on the security of your device. We recommend using a screen lock. The App’s data is kept in its private storage, which other apps cannot read.
9. Your Rights & Choices
- Turn off screen time at any time by removing Dayglass from Usage access in Android settings. Summaries already saved stay until you clear the App’s data or they pass 400 days.
- Remove a wallpaper by choosing another wallpaper in Android settings.
- Clear app data through your Android device settings (Settings → Apps → Dayglass → Storage → Clear Data).
- Uninstall the App to permanently remove all of its data from your device.
- Delete Android backups of the App’s data in your Google Account (Google Drive → Storage → Backups).
10. Changes to This Privacy Policy
We may update this Privacy Policy from time to time, for example if a future version of the App adds a feature that needs the internet. We will update the “Effective Date” at the top of this policy and, where appropriate, tell you in the App.
We encourage you to review this Privacy Policy periodically. Continued use of the App after any changes constitutes your acceptance of the updated policy.
