54 | ## Advanced Features
55 |
56 | ### Presets System
57 | Canta's preset system allows you to create, manage, and share collections of apps for removal. This feature enables:
58 |
59 | * **Device Consistency**: Apply the same bloatware removal across multiple devices
60 | * **Community Sharing**: Share your carefully curated removal lists with others
61 | * **Quick Setup**: Rapidly configure new devices with proven app configurations
62 | * **Backup & Restore**: Save your uninstall preferences before major changes
63 |
64 | Presets are stored locally and can be exported as JSON for easy sharing. When importing presets, Canta automatically validates app availability on your device and filters out incompatible entries.
65 |
66 | [Learn more about Presets →](/presets)
67 |
68 | ## Privacy & Security
69 |
70 | ### Privacy-Focused
71 | Canta can operate without internet connection and collects no data whatsoever.
72 | There's no analytics or tracking built into the app.
73 |
74 | ::: warning NOTE
75 | Badges information and app descriptions are fetched from GitHub repository if connected to the internet.
76 | No data is uploaded whatsoever.
77 | :::
78 |
79 | ### Open Source
80 | Canta is licensed under LGPL-3.0, with its complete source code available on [GitHub](https://github.com/samolego/Canta). This transparency ensures you can verify the app's functionality and contribute to its development if you wish.

18 | ### Auto-update Bloat List
19 |
20 | **Description:** When enabled, Canta automatically checks for and downloads the latest app classification data from the [Universal Debloater Alliance](https://github.com/Universal-Debloater-Alliance/universal-android-preinstalled-lists) repository.
21 |
22 | - **Enabled (Default):** Ensures you have the most up-to-date information about apps, including newly identified bloatware and revised safety recommendations.
23 | - **Disabled:** Canta will use only the locally stored bloat list data without checking for updates.
24 |
25 | ::: tip
26 | Enable this setting to ensure you have the most accurate information about which apps are safe to remove.
27 | :::
28 |
29 | ### Confirm Before Uninstall
30 |
31 | **Description:** Shows a confirmation dialog before uninstalling selected apps.
32 |
33 | - **Enabled (Default):** Displays a confirmation dialog showing the number of apps you're about to uninstall, helping prevent accidental removals.
34 | - **Disabled:** Immediately proceeds with uninstallation when you tap the trash icon, without asking for confirmation.
35 |
36 | ::: warning
37 | We recommend keeping this enabled to avoid accidentally uninstalling important apps.
38 | :::
39 |
40 | ## Advanced Settings
41 |
42 | Canta includes advanced settings for power users who need more control over the app's behavior.
43 |
44 | ### Allow Unsafe Selections
45 |
46 | **Description:** Controls whether you can select apps that are marked with the 🟣 **Unsafe** badge for uninstallation.
47 | You can bypass this restriction by using presets, too.
48 |
49 | - **Disabled (Default):** Apps marked as unsafe cannot be selected for uninstallation, protecting you from accidentally removing critical system components.
50 | - **Enabled:** Allows selection of unsafe apps, giving experienced users full control over what they can uninstall.
51 |
52 | ::: danger IMPORTANT
53 | Enabling this setting allows you to select apps that could break vital system functionality. Only enable this if you understand the risks and know exactly what you're doing. There's a high chance you'll experience bootlooping!
54 | :::
55 |
56 | ### Bloat List URL
57 |
58 | **Description:** Specifies the source URL where Canta downloads app classification data, badges, and descriptions.
59 |
60 | - **Default:** Points to the Universal Debloater Alliance repository
61 | - **Custom:** You can specify an alternative source that follows the same data format
62 |
63 | This setting allows organizations or advanced users to maintain their own app classification databases.
64 |
65 | ### Commits URL
66 |
67 | **Description:** Defines where Canta checks for updates to the bloat list data.
68 |
69 | - **Default:** Points to the commits API of the Universal Debloater Alliance repository
70 | - **Custom:** Can be changed to track updates from alternative sources
71 |
72 | This works in conjunction with the "Auto-update Bloat List" setting to determine when new data is available.
73 |
74 | ::: tip ADVANCED USAGE
75 | The Bloat List URL and Commits URL settings are primarily intended for developers testing custom app databases.
76 | :::
77 |
78 | ## Hidden Features
79 |
80 | ### Select All
81 |
82 | For advanced users, Canta includes a hidden "Select All" feature that can be enabled by tapping the version number in Settings multiple times. This feature adds a "Select All" option when having "recommended" filter applied.
83 |
84 | ::: warning CAUTION
85 | Use this feature carefully, as mass uninstallation could affect device functionality.

32 | ## 📖 About
33 |
34 | Canta allows you to **uninstall pre-installed or user apps without root**, by leveraging [Shizuku](https://shizuku.rikka.app/).
35 | It integrates with the [Universal Debloat List](https://github.com/Universal-Debloater-Alliance/universal-android-debloater-next-generation/) to provide safe recommendations.
36 |
37 | - ✅ No root required
38 | - ✅ Detects previously uninstalled apps (even across reinstalls)
39 | - ✅ Works on Android **9.0+ (SDK 28+)**
40 | - ⚠️ No *permanent* bricking (If you uninstall **critical apps**, you can experience bootloop and have to **factory reset**!)
