Privacy Policy — NubloidPlus

1. Who we are

• Android app: NubloidPlus
• Windows companion app: Nubloid Desktop
• Contact: contato@nubloid.com.br

2. What Nubloid does

• Local file transfer over your local network (Wi-Fi/LAN), authorized with a temporary token and automatic expiration (TTL).
• Optional advanced mode: connects to PC/Windows via Nubloid Desktop. This mode may require advanced Android settings (e.g., developer options/debugging), enabled only by the user.

3. Data we do NOT collect

• No accounts, no login, no proprietary cloud.
• No data is collected or sent to Nubloid servers.
• No selling/sharing of data for advertising purposes.
• No ads, and no intent to include them.

4. Data processed locally (to make things work)

Nubloid may process locally and/or transmit directly between your own devices, only by your action:

• Files you select to send/receive via local transfer.
• Operational transfer metadata (e.g., progress, file count, token/TTL, offer identifier).
• Minimal technical status/diagnostic data (e.g., session state, selected profile, basic performance telemetry shown in Desktop).

Important: transmissions happen only between devices you choose (Android ↔ Windows PC) and are not sent to Nubloid servers.

5. How local transfer works (summary)

• LAN transfer is opt-in: it only happens when you tap Send/Receive.
• A temporary token is shown and expires automatically (TTL).
• You can end the offer manually at any time.
• Content is protected with per-offer/per-session encryption and keys are not reused across offers.

6. Security & privacy by design

• Surface separation: advanced mode avoids unnecessary exposure on your local network.
• Ephemeral sessions: authenticated with temporary identifiers per session, with authorization after “connect”.
• Expiry & manual control: token/TTL and explicit user action to start/stop transfers.
• Abuse mitigation: basic request limits and controls against misuse.

7. Permissions and why

• INTERNET / NETWORK STATE: local communication and required routes.
• WIFI STATE / MULTICAST: local discovery and pairing/transfer facilitation.
• FOREGROUND SERVICE / DATA SYNC: keep transfer/session active with notification.
• POST NOTIFICATIONS (Android 13+): show notifications while an offer/transfer is active.

8. Local storage (Nubloid Files / sandbox)

Received files may be stored in a local Nubloid area (“Nubloid Files” / sandbox) for organization. You can manage these files on your device.

9. Children and sensitive data

Nubloid is not designed to collect sensitive data. Minors should use it under responsible adult supervision, especially when using advanced PC connectivity.

10. Third-party services (stores & system)

Google Play distribution and the Android system may collect data per Google/device maker policies (e.g., install metrics). This is outside Nubloid’s control.

11. Open-source software

Nubloid uses open-source components and third-party libraries (e.g., Ktor, AndroidX/Compose and, on Desktop, tools related to scrcpy and bundled dependencies). Applicable licenses may be provided in-app and/or on this page.

12. Changes to this policy

We may update this policy to reflect product changes or regulatory requirements. The effective date will be updated when changes occur.
