Privacy Policy

Last updated: June 17, 2026

Langulu (“the app”, “we”) is a translation app. This policy explains what happens to your data when you use it. The short version: we don’t run servers and we don’t collect or store your personal information.

1. Information you provide

• Text you enter and audio you record are sent from your device directly to OpenAI to perform translation and speech-to-text. We do not receive, store, or have access to this content.
• Your OpenAI API key is supplied by you and stored only in your device’s secure Keychain. It is never transmitted to us and is sent only to OpenAI to authorize your requests.

2. Microphone

The microphone is accessed only while you are actively recording a voice clip. The recorded audio is sent to OpenAI for transcription and is not retained by the app afterward.

3. Third-party processing (OpenAI)

Translation and transcription are performed by OpenAI. Your submitted text and audio are processed under OpenAI’s privacy practices. Please review the OpenAI Privacy Policy to understand how they handle data.

4. What we do not collect

We do not use analytics, advertising, or tracking. There are no user accounts. We do not collect your name, location, contacts, or device identifiers.

5. Children

Langulu is not directed to children under 13, and we do not knowingly collect information from them.

6. Changes

We may update this policy from time to time. Material changes will be reflected on this page with a new “Last updated” date.
