We collect only the minimum data necessary for the App to function.

a) Content You Provide

  • Video and audio files recorded or imported by you.
  • Caption text generated from your videos.

  • Your email address.
  • The content of your message.
  • Any attachments you voluntarily provide.

This information is used solely to respond to your request.

d) Analytics (PostHog) — Basic Usage Counts Only

We use PostHog to collect limited, privacy-preserving analytics so we can understand basic app usage and improve the product.

What we collect (examples):

  • Number of caption generations (count only)
  • Number of exports (count only)
  • Number of saves (count only)

Device identity / accounts:

  • Analytics are associated with a pseudonymous app/device identifier generated by the analytics SDK.

Opt-out:

You can disable analytics at any time in the App's Settings (if available), or by contacting us at support-viter@drobinin.space.

We Do NOT Collect

  • Names, usernames, or account credentials.
  • Location data.
  • Contacts.
  • Identifiers for advertising purposes (e.g., IDFA).
  • Payment or billing information (payments are handled by Apple).
  • Caption content, media content, or user-generated text as part of analytics.

4. How We Use Information

We use information strictly to operate and improve the App:

  • Record and edit videos.
  • Generate captions using on-device speech recognition.
  • Save projects locally on your device.
  • Export videos to your photo library.
  • Respond to support inquiries.
  • Measure basic feature usage (counts only) to improve stability and user experience.

We do not use your data for advertising, marketing, profiling, or AI model training.

5. Speech Recognition & AI Processing

Caption generation uses:

  • Apple Speech framework (on-device), or
  • Optional on-device ML models (e.g., Whisper).

Audio is processed locally on your device. No audio or video is sent to external servers for transcription.

6. Data Storage and Security

a) Local Storage

  • Projects, captions, and videos are stored locally on your device.
  • You can delete them at any time from within the App.

b) Security Measures

  • iOS sandboxing and system-level encryption.
  • No external databases containing user content.
  • No remote access to your projects.

Despite best practices, no system is 100% secure.

7. Third-Party Services

a) PostHog (Analytics)

We use PostHog as a data processor for limited analytics described in Section 3(d).

Hosting / region:

We use PostHog Cloud EU (hosted in the EU) to process analytics data.

b) Apple Services

Apple may collect data according to its own privacy policies when you:

  • Download the App from the App Store.
  • Use system speech recognition.
  • Save videos to Photos.

Please review Apple's Privacy Policy for details.

8. Data Retention

  • Media and projects remain on your device until you delete them.
  • Support emails are retained only as long as necessary to resolve your request.
  • Analytics event data is retained for a limited period for product measurement and improvement (we aim to keep this minimal and can delete it upon request where feasible).

9. Legal Basis for Processing (GDPR)

Where applicable, data processing is based on:

  • Performance of a contract — providing App functionality.
  • Legitimate interests — responding to support requests and improving the App using limited, privacy-preserving analytics.
  • Consent — when you voluntarily contact support, and where required by local law for analytics preferences.

You may object to analytics processing by disabling analytics in Settings (if available) or by contacting us.

10. Your Rights

Depending on your jurisdiction, you may have the right to:

  • Access information we hold about you (if any).
  • Request deletion of support correspondence.
  • Object to certain processing or withdraw consent where applicable.
