Overview
Tiny Kit is an Android app by Sailor Lux for artists. It brings together the tools that used to be separate apps: floating reference images and grid overlays (Reference), palette and colour tools (Color), pixel-art tools (Pixel) and sprite-sheet tools (Sprite).
Sailor Lux does not collect, sell or share personal data from the app, and the app has no accounts. The images you pick, your settings and the files you export stay on your device. Two features involve Google services and may process some device data: ads (Google AdMob) and the one-time purchase to remove ads (Google Play Billing). Both are explained below.
Images & files you choose
When you choose an image or file, Android's own system file picker opens. Tiny Kit gets access only to the files you pick. It does not get broad access to your photo library or files.
The app reads the pixels of a picked file to do its job: show a reference, build a palette, resize or batch-process an image, or cut a sprite sheet. For picked images it also reads the EXIF orientation tag so the image is shown the right way up. No other file metadata is read.
Picked files are processed in memory on your device. The app never uploads them or sends them to Sailor Lux.
What the app saves
Tiny Kit remembers your in-progress work and preferences in private storage that only the app can read. The app turns off Android's automatic cloud backup and device-to-device transfer for this data, so it does not leave your device through Android's backup system.
When you save a result, the app writes a file to your gallery or storage using Android's standard MediaStore or file-picker APIs:
| Tool | What it can save | Where |
|---|---|---|
| Color | PNG images and text palettes | Pictures or Downloads, in a Tiny Color Kit folder |
| Pixel | Processed PNG images | Pictures |
| Sprite | PNG frames and GIF files | Pictures, in a Tiny Sprite Kit folder, or a folder or file you choose |
| Reference | Nothing. It only shows overlays. | — |
Files you export follow the backup settings of your gallery app or Google Account. That is outside the control of Tiny Kit.
Advertising
Tiny Kit shows ads through Google AdMob (Google Mobile Ads SDK). The app shows a full-screen ad only when you return to the home screen from a tool, and at most once every three hours. You can remove ads with a one-time purchase (see Purchases).
Where the law requires it, the app first shows a consent form from Google's User Messaging Platform. The app requests ads only if your consent choice allows it.
To serve and measure ads, Google may collect and use data from your device, such as your advertising ID and other device identifiers, IP address (used to estimate an approximate location), device and app information, diagnostics and ad interactions. Sailor Lux does not receive this data. You can reset your advertising ID or opt out of ad personalisation in your Android settings. See Google's Privacy Policy and how AdMob uses data.
If you have removed ads, the app does not request any ads.
Purchases
Tiny Kit offers one optional in-app purchase, Remove ads, a one-time payment through Google Play Billing. Google Play processes the payment. Sailor Lux never sees or stores your card or payment details.
The app asks Google Play whether you own the purchase, and keeps a simple yes/no setting on your device so ads stay off. Your purchase is tied to your Google account and is governed by Google's terms.
Permissions we request
Tiny Kit requests only what its features need:
| Permission | Why |
|---|---|
| SYSTEM_ALERT_WINDOW | Show reference images and grids above other apps, only when you ask |
| FOREGROUND_SERVICE, FOREGROUND_SERVICE_SPECIAL_USE | Keep that overlay running while you draw |
| POST_NOTIFICATIONS | Show the persistent local notification Android requires while the overlay runs |
| WRITE_EXTERNAL_STORAGE (Android 9 and below only) | Save exported images to your gallery on older Android versions |
| INTERNET, ACCESS_NETWORK_STATE | Let the ads and Google Play purchase features work |
| BILLING | Let you buy "Remove ads" through Google Play |
On Android 10 and newer, the app needs no storage permission. Tiny Kit does not request camera, microphone, contacts, location, call log, SMS or broad photo-library access.
Internet access
Tiny Kit uses the internet only for ads and for checking and making purchases with Google Play. Your images and files are never sent over the network by the app. If you tap "Privacy Policy" in Settings, this page opens in your device's browser.
Analytics & crash reporting
Tiny Kit includes no analytics or crash-reporting SDK of its own, such as Firebase or Crashlytics. The only data collected by third-party code is what the Google Mobile Ads SDK collects, as described in Advertising.
Third-party code
- Google Mobile Ads SDK (AdMob) and Google User Messaging Platform: ads and consent. These connect to Google and may collect the data described above.
- Google Play Billing Library: the "Remove ads" purchase.
- AndroidX and Kotlin libraries (Compose UI, DataStore, lifecycle, EXIF): run on your device and do not transmit data.
- An open-source GIF encoder and decoder, included in the app, used on your device to read and write GIF files.
Children's privacy
Tiny Kit is a general-audience creative tool. It is not directed at children under 13, and Sailor Lux does not knowingly collect personal information from children.
Data retention & your controls
- Delete an exported image, palette or GIF from your gallery or file manager, like any other file.
- Remove a reference image from inside the app at any time to release its file access.
- Clear the app's storage or uninstall it in Android Settings to erase every saved preference and cached image.
- Reset your advertising ID or opt out of ad personalisation in your Android settings.
There is no account to delete and no Sailor Lux server holding your data. Data held by Google (ads and purchases) is governed by Google's policies.
