Privacy Policy

1. Who we are and how to contact us

The provider is Apps & Devs S.R.L. For privacy questions or requests, contact office@appsdevs.ro and mention “Network Helper”. Our website is appsdevs.ro.

This policy applies to Network Helper, not automatically to every application we may publish. Each application’s policy is listed in our app privacy directory.

2. Information used by network tools

The app processes information you enter and information returned by your device or the servers you test. This may include IP addresses, hostnames, network interfaces, device names, available MAC addresses, response times, DNS records, HTTP requests and responses, and MQTT topics and messages.

• Ping, Traceroute and device discovery: the app sends diagnostic packets to the addresses you select and may perform name resolution through the device’s configured resolver. Network devices and destination servers can see the network traffic and the source address visible to them.
• DNS lookup: the queried domain and record type are sent directly to the DNS server shown in the tool. The default is Google Public DNS at 8.8.8.8; you can enter another server. That resolver receives the query and your externally visible source IP address. See Google Public DNS privacy information.
• HTTP client: the selected server receives the URL, parameters, headers, request body and any Basic authentication credentials or Bearer token you choose to supply. Its response is displayed in the app.
• MQTT Explorer: the broker you select receives the client ID, login details if supplied, subscriptions, topics and messages you publish. Other subscribers may receive published messages according to the broker’s access rules.
• Wake-on-LAN: the target MAC address is included in a magic packet sent to the broadcast address and port you select.
• Vendor lookup: available MAC prefixes are matched against a vendor database bundled with the app, rather than uploaded to a separate vendor lookup service.

These tools do not upload their results, passwords, tokens or MQTT payloads to an Apps & Devs diagnostic server. The app does not require an account with us. The servers and brokers you choose operate under their own privacy and retention rules.

3. Google AdMob advertising

Network Helper includes banner advertising through the Google Mobile Ads SDK (AdMob). Advertising-related processing is separate from the diagnostic tools described above.

Google’s SDK can collect and share the device’s IP address, advertising or other device identifiers, ad/app interactions, and diagnostic or performance information. An IP address may be used to infer an approximate location. These data support advertising, measurement and fraud prevention; processing depends on the SDK, available identifiers, settings and applicable consent choices.

We do not deliberately supply the contents of your HTTP requests, MQTT messages, credentials or local device-discovery results as advertising data.

The app integrates Google’s User Messaging Platform (UMP) to request advertising privacy choices where required. When a consent form is shown, it describes the available purposes and choices. Android settings also let you manage or delete your advertising ID; this is separate from the choices in a consent form. Contact us if you need help with privacy choices.

Read Google’s Privacy Policy, how Google uses information from partner apps, and Google Mobile Ads data disclosures for details.

4. Device access and local preferences

Internet and network-related access are used for diagnostics and advertising. Advertising identifier and Android ad-services permissions can be included by the advertising SDK. Network Helper does not request access to your contacts, camera, microphone or precise GPS location for its current tools.

Your light/dark/system theme preference is stored locally using the device’s application preferences. Diagnostic screens and connection fields use in-memory state; the current app does not provide a persistent diagnostic-history database or cloud synchronization. Advertising components may separately keep SDK settings and consent information on the device.

5. Retention and deletion

Diagnostic inputs and results are held in the relevant screen’s memory and are not intentionally saved as a permanent history by the app. Leaving a screen or ending the app session releases its state; this is not a guarantee of secure memory erasure. Local preferences remain until changed or removed through Android’s app storage controls. Clearing app storage removes local app settings; uninstalling normally removes local app data, subject to Android backup and restore settings.

Data already sent to a DNS provider, HTTP server, MQTT broker, advertising provider or email service is not deleted by clearing the app. For example, an MQTT broker may retain a published message when you select the retain option. Those recipients apply their own retention and deletion policies.

Google determines retention of advertising data as described in its policies, including Google’s retention information. We do not maintain a copy of Google’s individual advertising records.

If you email us, we receive your email address and the information you include. We use that correspondence to respond and retain it for handling the request and any applicable legal obligations. You can ask us to delete correspondence we hold, subject to those obligations.

6. Security and data transfers

Traffic goes directly from your device to the destinations used by each tool or SDK. Google states that its Mobile Ads SDK encrypts collected data in transit using TLS. Diagnostic traffic depends on the chosen protocol: use HTTPS for sensitive HTTP requests and enable TLS for MQTT. Plain HTTP, MQTT without TLS, DNS over UDP, Ping and Wake-on-LAN do not provide equivalent transport encryption. Use the tools only on networks and systems you are authorized to test.

Google or the server operators you select may process information outside your country, including outside the European Economic Area. Their published policies explain the safeguards and processing locations applicable to their services. No internet transmission or device storage can be guaranteed completely secure.

7. Purposes, choices and privacy rights

We process the data needed to perform the network operations you request and respond to support inquiries. Where EU/EEA data-protection law applies, the relevant bases may include providing the requested service, legitimate interests in support and security, and consent for advertising processing where required. Google describes its own purposes and legal bases in its privacy notices.

Depending on the law that applies and the information we hold, you may request access, correction, deletion, restriction, portability, or object to processing. Where processing is based on consent, you may withdraw that consent for future processing. Write to office@appsdevs.ro. We may need proportionate information to verify a request, and cannot delete records held solely by an independent server operator or Google on their behalf.

You can also complain to your local data-protection authority. In Romania, this is the ANSPDCP. Network Helper has no developer-hosted user accounts to delete.

8. Children and changes to this policy

If you are a parent or guardian and believe a child has provided personal information to us, please contact us so we can review the request and address information within our control.

We will update this page when the app’s data practices change. The date at the top identifies the latest revision. New permissions, integrations or account features may require additional disclosures before release.
