EmbadonPrivacy policy
Short version: Embadon collects no data. It has no account, no analytics, no advertising, no crash reporting and no servers. Your drawings stay on your device. The one-time purchase is handled entirely by Google Play or the App Store.
What the app does with your files
- You choose a PDF or DXF file with the system file picker, or open one from another app with "Open with". Embadon reads that one file, in memory, to show and measure it. It does not copy it elsewhere, upload it, or keep a list of the files you opened.
- If you add markup, it is saved on your device in the app's private storage, encrypted with AES-256-GCM, under a name derived from a hash of your file rather than its name or location. The encryption secret is held by the operating system's secure storage: the Android Keystore on Android, and the Keychain on iOS (readable only while the device is unlocked, never synced to iCloud, never moved to another device). Your original file is never modified. When you export, the copy is written to the place you pick in the system "save" dialog.
- Markup files are excluded from cloud backup and device-to-device transfer on Android, and from iCloud and device backups on iOS. Nothing is synced.
- If a PDF is password protected, the password you type is used once to open it and is not stored.
- Besides markup, Embadon remembers one thing between runs: whether the unlock has been bought (a yes or no in the app's private settings), so everything keeps working offline.
What the app does not do
- No analytics, advertising, tracking, profiling or crash reporting, and no third-party software kits other than the platform's own purchase library.
- No network connections of its own. Embadon contains no code that opens one, and the Android app requests no network permission. Its only permission is the Google Play billing permission that comes with the purchase library. Automated build checks look for networking code in every build.
- No access to your location, contacts, camera, microphone, photos or other files. Files are reached only through the system file picker, which gives the app access to the one file you choose.
- No cloud backup or device-to-device transfer of the app's data.
Purchases
The one-time unlock is bought through Google Play on Android and the App Store on iOS, under their own terms and privacy policies (Google, Apple). They process the payment and keep the purchase record. We receive no payment details, name or email address, and never see your Google or Apple account.
Embadon itself sends nothing. It asks the Play Store app (Android) or StoreKit (iOS) on your device whether the unlock is owned, then remembers the answer on your device. On Android, the Google Play Billing Library only talks to the Play Store app on your device. The library's optional extra Google components (Play services location, Google's telemetry transport and Firebase encoders) are not included in Embadon.
This website
This site is a set of static pages with one small script of our own that runs the interactive demo in your browser. It uses no cookies, no local storage, no analytics, no tracking and no third-party scripts, fonts or embeds, and the demo sends nothing anywhere. Like any website, it is delivered through a hosting provider (Cloudflare) whose servers process the technical data needed to deliver a page, such as your IP address, under its own privacy policy. We do not collect or receive any of it.
Children
The app is not directed at children and collects nothing from anyone.
Deleting your data
Uninstall the app, or clear its storage in Android settings. This removes all markup and the encryption secret. On iOS, deleting the app removes the markup files. The random encryption secret may stay in the Keychain until the device is erased or the app is reinstalled, but it protects nothing once the files are gone and contains no personal information.
Changes
If this policy changes, the new version will be published at this address with a new effective date.
