Privacy Policy
Effective Date: July 6th 2026
Last Updated: July 6th 2026
1. Introduction
This Privacy Policy explains how StreamDev Technologies OÜ (“we,” “us,” or “our”) collects, uses, and protects your information when you use our audio streaming application and Windows desktop client (together, the “Software”).
2. Data Controller Information
StreamDev Technologies OÜ
Narva mnt. 5
10117 Tallinn, Estonia
European Union
Email: contact@streamdevtech.com
3. Our Core Promise
No audio content is ever transmitted to our servers or stored. All audio streaming occurs directly between your devices on your local network. Audio data never leaves your devices and is never sent to, recorded by, or accessible to our infrastructure.
4. Information We Collect
Our Software does not require user accounts or registration. We collect limited, pseudonymous technical information solely for diagnostic and reliability purposes. We do not use any third-party analytics platforms (no Google Analytics, no Firebase, no Crashlytics).
4.1 Device Information
- Device model and operating system details
- App version information
- Pseudonymous device identifiers (salted hash — we cannot identify you from this)
4.2 Connection Data
- Network connection type (USB or Wi-Fi) and the phone’s network interface name (e.g.
wlan0) - Local network configuration needed to diagnose connection failures: local IP addresses of the phone and desktop, gateway, broadcast, DHCP server, and subnet mask (these are private LAN addresses, not your public internet address)
- Connection quality metrics (latency, packet loss)
- Connection timestamps and session duration
- Desktop operating system and protocol version
4.3 Always-On Reliability Diagnostics
The Software sends pseudonymous, always-on diagnostics to our own servers. These are essential for detecting and fixing faults — including kernel-driver issues that can crash the user’s machine — and are used solely to diagnose problems and improve the software.
Windows desktop diagnostics include:
- A persistent, random
windows_client_id(a random GUID stored locally, used only to track whether a specific Windows installation has recurring issues over time — it is not linked to your phone, your identity, or any payment information) - Installer lifecycle events (install started, driver result — these carry no client identifier)
- Client startup, driver readiness status, update outcomes
- Stream quality summaries (packet counts, timing metrics — never audio content)
- Sanitized error codes (never raw error messages, file paths, or usernames)
Mobile diagnostics include:
- Permission grant/deny results, paywall and purchase flow outcomes
- Ad consent and load/show failures
- Recording-start failures
All diagnostics are:
- Pseudonymous: random identifiers scoped to a single domain (Windows id stays in Windows events; mobile device id stays in mobile events) — we never build a cross-device identity graph
- Minimal: closed set of known event types with validated property schemas; no free-form text, no file paths, no usernames, no machine names
- Self-hosted: stored only on our own EU infrastructure, never sent to third-party analytics or data platforms
4.4 What We Do NOT Collect
- Audio content (our core promise)
- Raw usernames, machine names, or hardware serial numbers
- MAC addresses or file paths
- Raw exception messages or stack traces
- Any data that could directly identify you as an individual
5. Legal Basis for Processing
We process your data based on the following legal grounds under GDPR:
- Legitimate Interests (Article 6(1)(f)): We collect always-on reliability diagnostics to maintain and improve our software, detect and fix kernel-driver faults, and ensure stability. A documented Legitimate Interest Assessment (LIA) is available upon request.
- Consent (Article 6(1)(a)): For ad personalization settings managed by the mobile app’s consent framework (UMP/TCF), which governs ad-related data processing only and is separate from first-party diagnostics.
6. Purpose of Data Collection
We use the collected information exclusively for:
- Detecting and fixing kernel-driver faults and application crashes
- Monitoring installer success rates and diagnosing installation failures
- Understanding stream quality and connection reliability across software versions
- Fixing bugs and improving software stability
- Providing technical support when requested
7. Data Storage and Security
7.1 Location
All data is stored on secure servers operated by Hetzner within the European Union. Your data never leaves the EU.
7.2 Security Measures
We implement appropriate technical and organizational measures to protect your data, including:
- Encrypted data transmission
- Secure server infrastructure
- Limited access controls
- Regular security assessments
7.3 Data Retention
- Reliability diagnostics: retained for as long as needed to diagnose faults and track reliability across software versions
- Operational logs: rotated on standard schedules
- User support bundles: retained per explicit policy, deleted upon resolution
You may request deletion of your data at any time (see Section 9).
8. Third-Party Services
8.1 RevenueCat
Used for subscription management and in-app purchase processing. RevenueCat may collect:
- Purchase transaction data
- Subscription status and history
- Device identifiers for purchase validation
RevenueCat is provided by RevenueCat, Inc. For more information, see RevenueCat’s privacy policy.
8.2 Google AdMob
Used for displaying ads in the free tier of the mobile app. Ad personalization is governed by the mobile app’s consent framework (UMP/TCF) and is separate from our first-party diagnostics. For more information, see Google’s privacy policy.
We do not use Google Analytics, Firebase Analytics, or Firebase Crashlytics.
9. Your Rights
Under GDPR, you have the following rights:
- Access: Request a copy of your personal data
- Rectification: Request correction of inaccurate data
- Erasure: Request deletion of your data (“right to be forgotten”)
- Restriction: Request limited processing of your data
- Portability: Receive your data in a portable format
- Objection: Object to certain types of processing
- Automated Decision-Making: We do not use automated decision-making
Important Note About Exercising Your Rights
Our Software does not use user accounts. To exercise your rights, please contact us at contact@streamdevtech.com and provide:
- Your device ID (found in the App settings) or your Windows client ID (found in
%LocalAppData%\Micstream\client_id) - Approximate dates when you used the Software
Because our identifiers are pseudonymous and domain-scoped, we may not always be able to link data across platforms. In such cases, your data is effectively anonymous and not personally identifiable.
10. Children’s Privacy
Our Software is not intended for children under 16. We do not knowingly collect personal information from children under 16. If you believe we have collected such information, please contact us immediately.
11. Data Breach Notification
In the event of a data breach that is likely to result in risk to your rights and freedoms, we will notify you and the relevant supervisory authority within 72 hours of becoming aware of the breach.
12. Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of any material changes by:
- Posting the new Privacy Policy on our website
- Updating the “Last Updated” date
