Privacy Policy

Introduction

We, the owner of chama.pro domain and developer of iperf3 Client application, take your privacy seriously. This policy describes how we collect, use, and protect your information when you use our application.

For privacy inquiries, you can contact us at: chamav@gmail.com

Data We Process

When using the iperf3 Client application, we may process the following categories of data:

  • Diagnostic events: information about app performance, errors, and functionality
  • Advertising identifiers: GAID (Google Advertising ID), OAID (Open Advertising ID), IDFA (Apple ID for Advertisers)
  • Third-party SDK data: information collected by advertising and analytics SDKs
  • Device technical data: device model, OS version, app version
  • Test results: network test data (stored locally)

Important: In server mode, the application does not send data to third parties; network connections are initiated by external clients on the user-specified port.

Advertising and Google AdMob

We use Google AdMob to serve ads in the app. As a consequence of using Google services, Google may collect and process certain data (e.g., the Google Advertising ID, IP address, device and app information) to deliver, measure and improve ads.

Consent and choices

For users in the EEA, UK and Switzerland, we collect consent using Google's User Messaging Platform (UMP). If you do not give consent, we will show only non-personalized ads (NPA) or no ads, according to our UMP configuration.

For users in certain U.S. states, you can exercise your "Do Not Sell or Share My Personal Information" right in the in-app privacy settings (via the UMP message). When you opt out, AdMob will limit data use accordingly.

You can also control ad personalization in your Google account (My Ad Center): https://safety.google/privacy/ads-and-data/

Withdraw or change consent (Privacy Options Form)

You can review and change your advertising choices at any time via the in-app Privacy Options Form. Open: Settings → Privacy → Manage Ads. The form will show your current choice (personalized / non‑personalized / opt‑out) and let you update it.

Purposes of Processing

We use collected data for the following purposes:

  • Display relevant advertising to support the free app model
  • Analyze app usage for improvement
  • Diagnose technical issues and improve stability
  • Provide technical support to users
  • Comply with legal requirements

Legal Basis (for EEA)

For users in the European Economic Area, we rely on the following legal bases, depending on the processing activity:

  • Personalized advertising: Consent (Art. 6(1)(a) GDPR). Ads are personalized only after you grant consent via UMP.
  • Non‑personalized advertising: Shown when consent is not granted; limited processing necessary to deliver ads. You can continue using the app with only non‑personalized ads.
  • Aggregated analytics and service improvement: Legitimate interests (Art. 6(1)(f) GDPR), with data minimization and opt‑out options where available.
  • Crash/error diagnostics: Legitimate interests (Art. 6(1)(f) GDPR) to maintain stability and security; no PII is included in reports.
  • Core app functionality: Performance of a contract (Art. 6(1)(b) GDPR), to provide requested features.

Website cookies and tracking

This website (chama.pro) currently does not use analytics or advertising cookies and does not embed third‑party trackers. Only strictly necessary technical resources are loaded to render the pages.

If we introduce analytics or other optional technologies in the future, we will provide a clear notice and controls. You can also manage cookies and site data in your browser settings at any time.

Error Diagnostics (Sentry)

To ensure application stability, we use Sentry service for automatic error information collection:

  • Purpose: stability diagnostics and technical issue resolution
  • Data collected: error information, app version, device model, OS version
  • Personal data: we do NOT send personally identifiable information (PII) in error reports
  • Data transmission: all data is transmitted using secure HTTPS protocol
  • Retention period: data is automatically deleted after 30 days

Diagnostic data collection helps us quickly fix errors and improve application quality.

Third‑party partners and disclosures

We integrate the following third‑party SDKs/services. They act as independent controllers or processors, as described in their policies:

Data shared is limited to what is necessary for the stated purposes. All partners are contractually bound to process data lawfully and implement appropriate safeguards.

Security

We apply technical and organizational measures appropriate to the risk, including transport encryption, access controls, and data minimization.

International Data Transfers

Where data is transferred outside the EEA/UK, we rely on appropriate safeguards such as the EU Standard Contractual Clauses (SCCs) and comparable UK mechanisms, together with technical and organizational measures to protect your data.

User Rights

Depending on your jurisdiction, you may have the following rights:

  • GDPR/UK GDPR: access, rectification, erasure, restriction of processing, data portability, objection to processing
  • CCPA: know about collected data, deletion, opt-out of sale, non-discrimination
  • Right to withdraw consent for data processing
  • Right to lodge a complaint with a supervisory authority

To exercise your rights, contact us at: chamav@gmail.com

Retention

We retain data only for as long as needed for the stated purposes or as required by law. Typical retention periods:

  • Advertising identifiers (GAID/IDFA/OAID): up to 24 months by advertising partners (e.g., Google). We do not store these longer than necessary in‑app.
  • Crash/error logs (Sentry): 30 days, then automatic deletion.
  • Aggregated analytics events: up to 14 months.
  • Consent records (UMP): up to 13 months to respect and audit your choices.
  • Technical server logs: up to 90 days for security and troubleshooting.
  • iPerf3 test results: stored locally on your device only; you can delete them by clearing app data.

Children

The app is not intended for children under 13 (or a higher age where required by local law). If you believe a child provided data, contact us and we will delete it.

Review and audit

We periodically review and audit this policy for compliance with GDPR and partner (e.g., Google/AdMob) requirements, and update it when our processing or applicable laws change.

Policy Changes

We may periodically update this privacy policy. For significant changes, we will notify you through the app or by email. We recommend checking this page regularly.
