6. Local-Only Features and Peer-to-Peer Data Handling

Sendu’s core functionality is built around local network communication. The features described below operate entirely within your local network (Wi-Fi or LAN) using direct peer-to-peer (P2P) connections between your devices. No data processed by these features is ever sent to, routed through, or stored on any external server operated by Sendu or any third party.

6.1 File Transfer

The file transfer feature allows you to send and receive files directly between devices connected to the same local network. Files are transmitted through a direct peer-to-peer connection between the sending and receiving devices. The content of transferred files is never uploaded to any cloud service, remote server, or intermediary. Once the transfer is complete, the Application does not retain any copy of the transferred files beyond what the receiving device has saved locally.

6.2 Stream to TV

The stream-to-TV feature allows you to cast or stream media content from your device to an Android TV or other compatible display on your local network. The media stream travels directly from your device to the target display over the local network. No media content is relayed through, buffered on, or recorded by any external server. The Company has no access to the content you stream.

6.3 Shared Folder

The shared folder feature enables you to make a folder on your device accessible to other devices on the same local network. Access to shared folders is limited exclusively to devices connected to your local network. No folder content, metadata, or file listing is transmitted outside your local network or stored on any remote server. When you stop sharing a folder or disconnect from the network, access is immediately revoked.

6.4 Download from Shared Folder

This feature allows you to browse and download files from a shared folder made available by another device on the same local network. Downloads occur through a direct peer-to-peer connection between the two devices. No download activity, file content, or transfer history is logged, transmitted to, or stored on any server outside your local network.

6.5 No External Access — Privacy by Design

Sendu’s local features are designed with a privacy-by-design approach:

This architecture ensures that your files, media, and shared content remain entirely under your control and within your local network at all times.

7. Payments and Transactions

All payments and financial transactions within the Application are handled entirely by third-party payment providers, including but not limited to:

We do NOT collect, store, or process any payment card details, banking information, or other financial data. All payment processing is subject to the terms and privacy policies of the respective third-party payment providers:

We may receive limited transactional information from these providers (e.g., confirmation of purchase, subscription status, expiration date) solely to grant you access to the purchased features or content.

8. Your Rights Under GDPR

In accordance with the GDPR and applicable French data protection law, you have the following rights regarding your Personal Data:

How to Exercise Your Rights

You may exercise any of these rights by contacting us at:

Hilda Labs 173 rue de Courcelles 75017 Paris France

Email: support.sendu@hilda-ai.com

All requests must be accompanied by proof of identity. We will respond within one (1) month of receiving your request. This period may be extended by two additional months if the complexity or volume of requests requires it; in such cases, we will inform you of the extension within the first month.

Account and Data Deletion

If you create an account, you may request deletion of your account and associated Personal Data:

Account deletion removes your account from our records and deletes associated Personal Data that we are not legally required to retain. Temporary deactivation or freezing of an account is not treated as deletion.

Deletion is completed within thirty (30) days, except where retention is required by law (for example certain transaction records for tax purposes).

Subscriptions: deleting your account does not automatically cancel a paid subscription billed by Apple or Google. You must cancel auto-renewal in your Apple ID or Google Play account settings. Billing may continue until you cancel there.

Filing a Complaint

You have the right to lodge a complaint with the French data protection authority:

Commission Nationale de l’Informatique et des Libertés (CNIL) Website: https://www.cnil.fr

We recommend contacting us first, as we are fully committed to resolving any data protection concerns you may have.

9. Data Retention

The Company retains your data only for the time necessary to provide you with its Services.

To the extent reasonably necessary or required to satisfy legal or regulatory obligations, resolve disputes, prevent fraud and abuse, or enforce our terms and conditions, we may retain limited information even after you have closed your account.

10. Sharing of Personal Data with Third Parties

We may share limited Personal Data with the following categories of third parties:

These third parties have access to your Personal Data only to perform their specific functions and are contractually obligated not to disclose or use it for any other purpose. Our third-party partners have been selected with care and are GDPR-compliant.

We do NOT sell, rent, or trade your Personal Data to any third party.

11. International Data Transfers

Some of our third-party service providers (such as Google and Firebase) may process data outside the European Economic Area (EEA). In such cases, we ensure that appropriate safeguards are in place, including:

12. Data Security

We implement appropriate technical and organizational measures to protect your Personal Data against unauthorized access, alteration, disclosure, or destruction. These measures include:

While we strive to protect your Personal Data, no method of transmission over the Internet or electronic storage is 100% secure. We cannot guarantee absolute security but are committed to maintaining industry-standard protections.

13. Children’s Privacy

Our Services are not directed to children under the age of 16 (or the applicable minimum age in your jurisdiction). We do not knowingly collect Personal Data from children under this age.
