1. Who we are
STL Viewer ("the app") is developed and published on Google Play by VELOX APP LTD ("we", "us"), a company registered in England and Wales under company number 17186614, with its registered office at 128 City Road, London, EC1V 2NX, United Kingdom.
This policy covers the STL Viewer Android app only. Our company privacy policy covers this website and emails you send us. For any privacy question, email [email protected].
2. Summary
The app has no accounts, no sign-in and no advertising, and it does not use the advertising ID. Your 3D files are never uploaded. We do not sell or share personal data.
3. Your files and data on your device
The app opens only the files you choose with Android's system file picker, or files you send to it with Share or Open with. It does not browse your storage and needs no storage permission. Files are read and displayed on your device and are never sent to us or to anyone else. What the app keeps for itself, such as settings, stays in its private storage on your device, and uninstalling the app deletes it.
4. Permissions
The app uses internet access only for the anonymous usage statistics and crash reports described below, for app settings fetched from Google Firebase, and for checking a Google Play purchase. It does not access your contacts, location, camera, microphone or advertising ID.
5. Usage statistics and crash reports
The app uses Google Firebase Analytics, Crashlytics and Remote Config to count how features are used, to find crashes and to fetch app settings. These reports contain app events (for example, that the Pro screen was opened), device model, Android version and a random app-installation identifier. They do not contain your name, contacts, your files, file names or contents, or the advertising ID. Google processes this data on our behalf, and it is deleted after 2 months.
The app collects these usage statistics and crash reports by default. You can switch them off at any time in Settings > Privacy; turning them off stops collection from then on and does not limit any feature of the app, including Pro.
6. Purchases
The optional one-time Pro unlock is processed entirely by Google Play. We never see your payment details. The app only asks Google Play whether the unlock was purchased, and keeps that yes/no answer on your device. There is no subscription.
7. Contacting us
The WhatsApp and email buttons open your own app with a prepared message that includes the app version, phone model and Android version. Nothing is sent unless you press Send.
8. Children
The app is not directed at children under 13 and does not knowingly collect data from children.
9. Changes and contact
If this policy changes, the new version will be posted on this page with a new date. Questions: [email protected].
