Chalkreel – Doodle Video Explainer
Chalkreel Privacy Policy
This Privacy Policy explains how the following Android apps published by Build CAD (“we”, “us”, “our”) handle information when you use them (each an “App”, together the “Apps”):
- Chalkreel – Doodle Video Explainer (Google Play, package
com.chalkreel)
Chalkreel works on your device. It has no accounts, no ads, no analytics and no tracking, and we run no servers that receive data from the app. The app does not have the internet permission. Your projects, recordings and videos stay on your device, or in the folder you choose to sync with. Permissions are used only for features you start, and purchases are handled entirely by Google Play.
At a glance
| Data | Where it is kept | Sent to us? |
|---|---|---|
| Projects, drawings, characters, brand kits and settings | On your device (and your sync folder if you turn sync on) | No |
| Narration, voice-over and screen recordings | Inside your project on your device | No |
| Images, videos and sounds you import | Copied into your project on your device | No |
| Videos, GIFs and subtitles you export | Where you save or share them | No |
| Pro purchase and subscription status | Google Play | No, we never see payment details |
| Usage analytics, crash reports, advertising identifiers | Not collected | No |
Information we collect
None. Chalkreel does not send your projects, recordings, usage, device identifiers or any other personal information to us, and it contains no advertising, analytics, telemetry or crash-reporting libraries. The app does not have the internet permission, so it cannot send anything anywhere by itself.
What stays on your device
Everything you make in Chalkreel is stored locally: projects, drawings, imported pictures and videos, narration and screen recordings, your character and expression library, brand kits and settings. You can delete any of it in the app.
Projects and settings are kept in the app's private storage, and uninstalling the app removes them. Android's own backup may copy Chalkreel's settings and library index (not your projects) to your Google account, encrypted by Android; you can turn this off in Android's settings.
Exported videos stay wherever you saved or shared them. Exported files contain what is in your project, so review them before sharing.
Permissions and how they are used
Chalkreel asks for a permission only when you start the feature that needs it, and works without it otherwise.
| Permission | Used for |
|---|---|
| Microphone | Recording narration, voice-overs and dialogue, and the sound of a screen recording when you turn it on. Recordings are saved inside your project. |
| Camera | The optional presenter bubble shown during a screen recording. Camera frames go only into that recording and are not stored anywhere else. |
| Screen recording | Recording your screen after you accept Android's screen-capture prompt. Android shows that recording is in progress. |
| Speech recognition | Timing captions to your narration. Chalkreel asks for on-device recognition. Where your device cannot transcribe a language offline, your device's speech-recognition service (for example Google's) processes that audio under its own privacy policy. |
Text-to-speech uses the text-to-speech engine and voices installed on your device.
Folder sync and shared projects
If you choose a sync folder with Android's folder picker (for example a Google Drive or Dropbox folder offered by its app), Chalkreel copies your projects and library into that folder, and people you share that folder with can open and edit those projects. The provider of that folder handles the copy under its own privacy terms. We cannot access it. You can stop syncing at any time.
Purchases
Chalkreel Pro is sold through Google Play Billing. Google Play processes the payment, keeps the receipt and manages renewals and cancellations; Chalkreel only asks Google Play which Pro products you own. We never receive your name, card or billing address. The Google Privacy Policy applies to purchase data.
Network access
Chalkreel does not contact any server operated by us. The app itself has no network access: purchase checks are made by the Google Play app on your device, sync is carried out by the folder's provider, and the Terms of Use and this policy open in your browser when you tap those links.
Children
Chalkreel is a general-audience creative tool. Because it does not collect personal information from anyone, it does not knowingly collect personal information from children.
Your choices
- Delete a project, recording or library item at any time in the app.
- Allow or revoke the microphone and camera permissions in Android's settings.
- Turn folder sync off at any time.
- Manage or cancel a Pro subscription in Google Play (Payments & subscriptions).
- Uninstall the app to remove its data from your device; store purchase records remain with the store.
Since we hold no personal data about you, there is nothing for us to access, correct, export or delete.
Changes to this policy
If Chalkreel ever handles data differently, this page will be updated and the effective date above will change before the new behaviour takes effect.
