STL Player – Privacy Policy

App: STL Player: 3D File Manager (Android, package com.bharat.stlplayer)
Effective date: 7 October 2026

In short: STL Player works entirely on your phone. It sends nothing over the internet and has no ads, no analytics and no accounts. We do not collect, store on any server, sell or share any personal data or files. The optional STL Player Pro subscription is paid through Google Play.

1. What the app accesses on your phone

Files and folders. To find 3D model files (STL, OBJ and ZIP files that contain them) and to let you browse, open, copy, move, rename, delete and share files, the app reads your phone’s shared storage. On Android 11 and later this uses the “All files access” permission, which you grant yourself in Android Settings after an explanation in the app; you can decline and choose individual folders instead, and you can turn the permission off at any time. On Android 8–10 the standard storage permission is used.
Photos and videos you create. When you tap Photo or Video in the 3D player, the picture or video is saved to your phone’s Pictures or Movies folder.

All of this happens on your device. Files are never uploaded by the app.

2. What the app stores

Only inside the app’s private storage on your phone:

a library index of the 3D files found (file name, folder, size, date, favourites, recently opened);
small preview pictures (thumbnails) of those models;
your settings (for example sort order, printer, material and metal choices, prices you typed).

This data never leaves your phone. It is deleted when you uninstall the app or clear its storage in Android Settings.

3. Sharing

A file, photo, video or details card is sent to another app (for example email or a messaging app) only when you tap Share and choose that app. What happens next is covered by that app’s own privacy policy.

4. No collection, no third parties

The app does not send any data over the internet.
No advertising, no advertising ID, no analytics or tracking libraries, no crash-reporting services.
No sign-in or accounts.
STL Player Pro (optional subscription that removes the STL Player watermark) is sold through Google Play’s billing system. Google Play handles the payment under Google’s privacy policy; STL Player never sees your card or other payment details. The app only asks Google Play on your phone whether your subscription is active and remembers that answer on the phone. You can cancel at any time in Google Play › Payments & subscriptions.
No data is sold or shared with anyone.

5. Children

STL Player is intended for adults (18+) and is not directed at children.

6. Security

Because the app keeps everything on your device and never transmits it, your data stays under your control and is protected by your phone’s own security (screen lock and Android’s app sandbox).

7. Changes to this policy

If a future version changes how data is handled (for example by adding an online feature), this page and the Google Play “Data safety” section will be updated before that version is released, and the effective date above will change.
