Privacy Policy

Last updated · November 28, 2025

This Privacy Policy explains how Captio ("the App", "we", "our") processes data when you use the App. Captio is developed by an independent individual developer based in Sweden. This policy applies to all users worldwide.

Captio provides subtitle generation and translation features for videos stored on your device. The App does not collect personal information, does not create user accounts, and does not store any user content on external servers.

1 · Information We Don't Collect

Captio does not collect or store names, email addresses, phone numbers, location data, personal identifiers, or user content on developer-controlled servers. The App does not maintain a backend infrastructure storing any user data.

2 · Information the App Processes

2.1 Videos and audio (on device only)

  • All videos you use remain on your device only.
  • Audio extracted from videos is stored temporarily on your device during processing.
  • Deleting the App removes all such data automatically.
  • We never upload videos or audio to our own servers.

3 · Third-Party Services

Captio uses trusted third-party services exclusively for real-time processing. These services process only what is required and, based on their documentation, do not retain your content afterward.

3.1 ElevenLabs API (audio processing)

  • Only extracted audio is sent to ElevenLabs.
  • ElevenLabs states uploaded audio is not stored after processing.
  • No video content is ever sent.

3.2 Google Cloud Translation API (text translation)

  • The App sends subtitle text to Google Translate.
  • Google states data sent to Cloud Translation is not logged or stored beyond processing.
  • No audio or video content is transmitted to Google.

4 · Analytics & Crash Reporting

Captio may use Firebase Crashlytics, Firebase Analytics and Apple App Analytics. These collect anonymous device model, OS version, crash logs and performance metrics — never linked to any personal identity.

5 · Subscriptions & Payments

  • All payments are processed exclusively through Apple's App Store.
  • Apple manages billing, refunds and purchase history.
  • Captio uses RevenueCat for entitlement management; no personal identifiers are shared.
  • The Developer does not process or store any financial data.

6 · Children's Privacy

  • The App is suitable for users of all ages.
  • Captio does not knowingly collect personal information from children under 13, in compliance with COPPA and GDPR-K.
  • Since no personal data is collected, children may safely use the App.

7 · GDPR (EU/EEA Users)

Under the GDPR, users have rights including access, deletion, and portability. Since Captio stores no personal data, these rights are fulfilled by uninstalling the App. Users may contact us with any GDPR-related concerns.

8 · Data Retention

Captio retains no user data on external servers. All content remains on the device unless deleted by the user.

9 · Changes to This Policy

We may update this Privacy Policy from time to time. Continued use of the App constitutes acceptance of any modifications.
