Proxy Server Privacy Policy

Last updated: 22 October 2026

Proxy Server is an Android application published under the Nerdosoft brand by Certus IT - Przemysław Zapaśnik, Poland (“we”, “us”). We are responsible as controller for the purposes and means of personal data processing that we determine in providing the app, integrating advertising and handling support. This responsibility is not limited to data sent directly to us. Google’s role in advertising is explained below. For support, problem reports and privacy questions or requests, email support@nerdosoft.com.

How the proxy works

Proxy Server runs an HTTP and SOCKS proxy and an optional PAC configuration server on your Android device. You do not need an account with us. We do not operate a remote proxy service: your proxy traffic is forwarded from your device to the destinations requested by connected clients, without passing through Nerdosoft servers.

To make these connections, the app processes client IP addresses, destination addresses, ports and traffic in memory. Hostnames may be resolved through your device’s network DNS configuration. The app does not record browsing history, destination URLs or the contents of forwarded traffic, and does not send them to us or use them for advertising. HTTPS traffic is relayed without decrypting TLS. Unencrypted HTTP traffic is processed as necessary to forward the request.

The proxy is not an encryption service. HTTP and SOCKS connections to the phone, including proxy authentication, are not themselves encrypted. Use trusted networks and appropriate access settings. Websites, DNS providers, network operators and other services you connect to process data under their own policies.

Data kept on your device

• Settings and credentials. The app stores your selected ports, network restrictions, preferences and saved profiles in private app storage. A proxy username and password, if configured, and the last confirmed Advanced purchase status are stored separately and excluded from the app’s Android backup and device-transfer rules. Ordinary settings, including selected IP addresses and profiles, may be backed up or restored by Android according to your device settings.
• Live statistics. Connection counts, transfer totals and client IP addresses are used locally to display activity. Advanced client statistics retain up to 256 client IP entries in memory. These are not a persistent browsing log and are not uploaded to us.
• Optional session history. If you enable session logging, the app keeps up to 100 session summaries on your device. They contain timestamps, protocols, transfer totals, connection counts and completion status, not client IP addresses, destinations, traffic contents or passwords. Older entries are replaced when the limit is reached. This history is excluded from Android backup. “Clear history” deletes the saved entries and switches logging off.
• Diagnostics. The app keeps local operational information such as listener events, response counters and process-exit information to help explain errors. Optional performance diagnostics measure relay timing and throughput without recording traffic contents or destinations.

Actions you choose to take

Connection test. When you tap “Test”, the app attempts a connection through your own proxy to www.google.com:443. This requires network access and may involve DNS resolution. Google and your network providers can receive the connection’s usual network metadata, including the outgoing IP address. The test does not send a diagnostic report to us.

Share setup and export. “Share setup” prepares the phone’s proxy addresses, ports, PAC URL and proxy username, but not the password, for an app you choose. CSV export saves session summaries to a location you choose, which may be a cloud storage provider. You control those copies and their recipients; clearing history in Proxy Server does not delete exported files.

Report a problem. A report is prepared for you to review and send using your email or sharing app. The email is addressed to support@nerdosoft.com. It may include app and Android versions, device model, local network addresses, listening settings, VPN status, notification and battery settings, recent process exits and diagnostic counters. It excludes proxy passwords, client browsing destinations and forwarded traffic contents. Nothing is sent to support automatically. If you contact us, we receive your email address, message and any report or attachments you choose to include. Avoid including passwords or other information that is not needed to resolve the issue.

We use correspondence to answer requests and investigate problems. Retention and deletion are described below.

Advertising and privacy choices

The free version integrates Google AdMob and Google’s User Messaging Platform (UMP). The current app configuration uses Google’s test advertising identifiers. Test ads should not be understood to mean that no communication with Google takes place.

Google’s Mobile Ads SDK can collect and share the device’s IP address (including to estimate general location), app and ad interactions, diagnostic information, and identifiers such as the advertising ID and app set ID. Google uses this information for advertising, measurement and fraud prevention. UMP communicates with Google to determine applicable privacy choices and manage consent. The app only requests ads when its purchase status and UMP permit them.

The SDK sends advertising identifiers and interaction data directly to Google, rather than to a Nerdosoft server. For advertising processing covered by the Google Ads Controller-Controller Data Protection Terms, we and Google act as independent controllers, each responsible for the purposes and means of its own processing. Google is not simply processing all advertising data on our behalf.

Advertising technologies may store or read information on your device, including advertising identifiers and other local storage, to deliver, measure and, where permitted, personalise ads. Where consent is required, the consent message provides information about the purposes and providers covered by your choices. The providers involved depend on the advertising configuration; their use of data is subject to the applicable notices and your choices.

Where required, a consent form is presented. When Google requires a privacy-options entry point, “Ad privacy options” is available in the app to review or change your choices. You can also manage the advertising ID in Android settings. Declining personalised advertising does not necessarily disable all ads or all processing needed to deliver permitted ads.

The one-time Advanced purchase removes all ads. Once the app recognises your confirmed purchase, it removes the banner and stops making new ad requests. This does not delete information already held by Google.

Read Google’s Privacy Policy, how Google uses information from apps and sites, and Google’s Mobile Ads SDK data disclosure.

Purchases and app reliability

Google Play Billing handles the Advanced purchase and restoration. The app receives purchase information, including purchase status and a purchase token, to acknowledge the purchase and provide access. We do not receive your payment-card details through the app. Google processes payment and account information under its own terms and privacy policy.

Google Play and Android may collect crash and performance information according to your device and Google settings. We can use reports made available through Android vitals to improve reliability. The app does not include Firebase Analytics, Firebase Crashlytics or a separate developer-operated analytics service.

Service providers and international processing

Data may be processed by Google for advertising, consent, purchases and platform diagnostics; by email providers when you contact us; and by apps or storage providers you select when sharing or exporting. Proxy destinations and DNS services receive the information needed for the connections you request. We do not sell your proxy traffic or browsing history.

Google and other providers may process data outside your country, including outside the European Economic Area. Their applicable privacy notices describe processing locations, retention and transfer safeguards. See Google’s data transfer frameworks. We do not control the retention of data independently held by these providers.

Security

Settings, proxy credentials and optional session history are stored in the app’s private storage, which Android isolates from other apps. The proxy credentials and cached purchase status are excluded from the app’s Android backup and device-transfer rules; session history is also excluded from backup. We do not operate a backend that receives proxy traffic.

Google states that data sent by its Mobile Ads SDK is encrypted in transit using TLS. This does not encrypt your connection to the proxy. Proxy authentication and HTTP or SOCKS connections to the phone are not themselves encrypted, although HTTPS payloads retain their own TLS protection. Set a proxy password and restrict “Listen on” to trusted networks to limit access. A password does not provide transport encryption.

Data retention and deletion

Live statistics and client IP statistics are held in memory and do not survive the app process ending. Settings and credentials remain in private app storage until you change them, clear app storage or uninstall the app. Optional session history retains at most 100 entries, replacing older entries when the limit is reached. You can delete it with “Clear history”, which also disables logging.

Android backups, exported files and information held by other services must be managed separately. Clearing local app data does not delete previously exported files, support emails or Google’s records. Google Play may restore a purchase after local app data is cleared.

We retain support correspondence for as long as needed to handle the matter and relevant follow-up, or to meet applicable legal obligations or establish, exercise or defend legal claims. You can request deletion at support@nerdosoft.com; we will explain any legal reason that prevents deletion. Google retains the data it collects according to its own policies and applicable user controls.

Children’s privacy

Proxy Server is a network utility and is not directed at children. The app does not ask for a date of birth or verify a user’s age. If you believe a child has provided personal information to us through support, contact support@nerdosoft.com so we can investigate and arrange deletion where appropriate. This contact process does not delete data independently held by Google or other providers.

Legal bases and your rights

Where European data protection law applies, we process personal data as needed to provide requested services and support, for our legitimate interests in resolving problems and maintaining a reliable app, to meet legal obligations, or on the basis of consent where required, including for advertising technologies. Local proxy processing is performed on your device to carry out the connections and settings you choose.

Depending on applicable law, you may request access, correction, deletion, restriction or portability of your personal data, and object to processing based on legitimate interests. You can withdraw consent without affecting processing that was lawful before withdrawal. Contact support@nerdosoft.com to exercise your rights. We cannot retrieve proxy traffic or local history that the app has not sent to us.

You may also complain to your local data protection authority. In Poland, this is the President of the Personal Data Protection Office (UODO).

Opening this policy on the website

Opening this page launches a website request from your browser. The website’s hosting provider, Cloudflare, processes network information needed to deliver and protect the page. The Nerdosoft website uses Google Analytics only after you give website analytics consent; you can change this choice in the website footer’s privacy settings. Website analytics choices are separate from the app’s advertising choices. See Cloudflare’s Privacy Policy and Google’s Privacy Policy.

Changes and contact

We may update this policy when the app or its data practices change. The current text will remain available at this address, with the revision date shown above. Where necessary, we will provide additional notice or request consent in the app.
