3Data We Collect & Why

3.1 Audio Data (Speech-to-Text Transcription)

When you initiate transcription, the app extracts the audio track from your selected video using FFmpeg — entirely on your device. This audio is then transmitted over an encrypted HTTPS connection to our API proxy (a Cloudflare Worker) which forwards it to the ElevenLabs Scribe v2 speech-to-text API.

Legal basis (GDPR Art. 6(1)(b)): Processing is necessary to perform the service you requested.

3.2 Crash Reports (Firebase Crashlytics)

If the app crashes, Firebase Crashlytics automatically collects:

• Device model and operating system version
• App version and build number
• Stack trace and error message at the time of the crash
• A randomly generated installation ID (not linked to your identity)

Legal basis (GDPR Art. 6(1)(f)): Legitimate interest in maintaining a stable, secure application.

3.3 Analytics Data (Firebase Analytics)

Firebase Analytics collects anonymous, aggregated usage data including:

• Screen views and navigation flows
• Feature interactions (e.g., export initiated, platform selected)
• App session length and frequency
• Device country/region (coarse, not precise location)
• Device type, OS version

No personal identifiers such as name, email, or IP address are collected.

Legal basis (GDPR Art. 6(1)(f)): Legitimate interest in improving the application based on usage patterns.

3.4 Performance Data (Firebase Performance Monitoring)

Firebase Performance Monitoring collects anonymous metrics such as app startup time, network request latency, and rendering performance. This data does not contain personal information or media content.

Legal basis (GDPR Art. 6(1)(f)): Legitimate interest in ensuring acceptable app performance.

3.5 Subscription & Purchase Data (RevenueCat)

If you purchase a subscription, RevenueCat receives information from Google Play Billing necessary to manage your subscription, including:

• Purchase token and transaction ID (provided by Google Play)
• Subscription status (active, expired, trial, etc.)
• Purchase history and renewal dates

RevenueCat does not receive your payment card details; those are handled exclusively by Google Play.

Legal basis (GDPR Art. 6(1)(b)): Processing is necessary to fulfil your subscription purchase and deliver paid features.

3.6 Data We Do NOT Collect

• Name, email address, phone number, or any account credentials
• Precise GPS location
• Contacts, microphone access beyond audio extraction, or camera roll metadata
• Advertising identifiers (IDFA, GAID) — no ads are served
• The video file itself (never leaves your device)
• The final captioned video output

4Third-Party Services

Each of these services operates under its own privacy policy. We have entered into appropriate data processing agreements with these providers where required under GDPR.

We implement appropriate technical and organisational measures to protect your data:
