                VniDrop has no user accounts and does not upload your transfer to a VniDrop file
                store. Files travel over an authenticated, end-to-end encrypted connection.
                VniDrop has no telemetry or analytics; a bug report is sent only when you submit one.

              <h2>Scope and who “VniDrop” means</h2>
              <p>
                This policy covers the official VniDrop website, the VniDrop applications for
                Android, iOS, macOS, Windows, and Linux, and the bug-report service configured by
                the official project. For an official release, VniDrop’s data controller is the
                individual publisher named in the applicable app-store listing. In this policy,
                “VniDrop,” “we,” and “us” also include the maintainers acting on that publisher’s
                behalf. The publisher can be reached at support@sudosy.fr.
              </p>
              <p>
                VniDrop is open-source software. A build distributed or operated by someone else
                may use different networking infrastructure, bug-report settings, or website
                hosting. That distributor is responsible for explaining its own practices.
              </p>
            </section>

            <section id="transfers" className="policy-section">
              <h2>What happens during a transfer</h2>
              <h3>File contents</h3>
              <p>
                The sender chooses files or folders on their device. VniDrop streams those bytes to
                an approved receiver and does not first upload them to a VniDrop-hosted storage
                bucket. The receiver saves the files to a destination they choose. Relayed traffic
                remains end-to-end encrypted.
              </p>
              <h3>Invitations and transfer metadata</h3>
              <p>
                A QR code, NFC tag, or <code>.vnd</code> file contains a transfer invitation. The
                invitation includes connection and content identifiers plus transfer metadata such
                as the transfer name, optional sender name, creation time, file count, and total
                size. It is a capability: anyone who receives it may be able to request the transfer
                while the share is active. Treat it like a private access link.
              </p>
              <h3>What peers and relays can see</h3>
              <p>
                A receive request can disclose the receiver’s chosen display or device name,
                application version, and a technical endpoint identifier to the sender. A direct
                connection exposes the peers’ IP addresses to one another. When a public relay is
                used, its operator can observe connection metadata such as source and destination IP
                addresses, connection time, and the amount of relayed data, but cannot read the
                encrypted transfer contents.
              </p>
              <div className="policy-note">
                <p>
                  Approval is required by default. If the sender selects “Anyone with this transfer,”
                  anyone holding the invitation may receive the files until sharing stops.
                </p>
              </div>

            <section id="local-data" className="policy-section">
              <h2>Information kept on your device</h2>
              <p>VniDrop stores the information needed to operate the app locally, including:</p>
              <ul>
                <li>device identity and networking keys used to establish secure connections;</li>
                <li>active shares, transfer history, receiver requests, progress, and status;</li>
                <li>app preferences, including access choices;</li>
                <li>download destinations and locally managed transfer data; and</li>
                <li>an anonymous installation identifier used only for bug-report correlation.</li>
              </ul>
              <p>
                This information remains until you remove the relevant history, stop or delete a
                share, clear the app’s data, or uninstall the app, subject to operating-system file
                behavior. Removing VniDrop history does not delete a file you already downloaded;
                delete that file through your operating system if you no longer want it.

            <section id="bug-reports" className="policy-section">
              <h2>Optional bug reports</h2>
              <p>
                VniDrop has no automatic telemetry, usage analytics, or crash auto-reporting.
                Nothing is sent to a bug-report service unless you explicitly submit a report.
              </p>
              <h3>User-submitted bug reports</h3>
              <p>
                A bug report is sent only when you press submit. It can contain what you say
                happened, what you expected, reproduction steps, an optional contact email, app and
                platform versions, an anonymous installation ID, device name and model, operating
                system, network and battery information, and optional recent logs. You can exclude
                logs before submitting.
              </p>
              <h3>Data deliberately excluded</h3>
              <p>
                Bug reports are designed to exclude transfer contents, invitations, and file paths.
                Before optional logs are sent, VniDrop applies rules intended to redact invitation
                tokens, endpoint identifiers, absolute paths, file and content URIs, and platform
                document identifiers. No redaction system is perfect, so review anything you type
                into a bug report and avoid including secrets.

                VniDrop is in early development. Features and data practices may change. When this
                policy changes, we will update the effective date and version at the top of the page
                and publish the revised text with the project. Material changes should be called out
                in release notes or the application where practical.
