LOCUTOR · Privacy policy

Last updated: 11 November 2026

Locutor is an app for Windows and Android that recognises the song you are listening to (on Spotify, YouTube Music, etc.) and has AI “radio hosts” talk about it out loud, like a personal radio station. This policy explains, in plain language, what data the app processes and why. The Spanish version is the reference version; this translation is provided for convenience.

1. Who is responsible

The data controller is the developer of Locutor, whose trader details are shown on Locutor’s Google Play listing. For any privacy matter you can write to: rfabregamiralbell@gmail.com.

2. What data we process

• Title and artist of the song that is playing. It is read from the device’s “now playing” system (on Windows, SMTC; on Android, notification access, of which only the music information is used, never your messages). With that title/artist, the app queries public music sources (MusicBrainz, Wikipedia, Genius, Last.fm, iTunes, Deezer and LRCLIB) to build a fact sheet about the song (year, authorship, meaning, context, cover and synced lyrics); that sheet, with the title/artist, is sent to the AI you connect (the provider you choose in the app, with your key) to write the comment. No audio is accessed, nothing is recorded, the microphone is not used.
• Email address: only if you choose Sign in with Google. It is used to identify you and manage your plan. Without signing in, you use the app as a guest.
• Anonymous device identifier: a random code generated on your device for the guest session. It does not identify you personally.
• Plan usage data: how many AI comments you have created today, to apply the free plan’s limit. It is counted on your device.
• Payment data: if you subscribe to Premium, payment is processed by Stripe (Windows) or Google Play (Android). We do not store your card.
• Your own keys: the AI key you connect (and, if you use them, those of your voice services: ElevenLabs, Cartesia, Microsoft Azure, Google Cloud or Deepgram) is stored encrypted only on your device: on Windows with the system’s DPAPI encryption; on Android with the system key store (Android Keystore). It is not stored on our server: it goes directly to the provider you choose.

3. Who it is shared with

For the app to work, some data is sent to third-party services, each with its own privacy policy:

• The AI provider you connect, among those offered in the app: Google Gemini, Groq, Mistral, OpenAI, Anthropic, DeepSeek, xAI, Cerebras, OpenRouter, Hugging Face, SiliconFlow, Moonshot, Z.ai, Sarvam, Upstage, PLaMo, SEA-LION or Maritaca (or a model you run on your own computer) — it writes the comment and, if you choose “your AI’s voice”, turns it into speech. It receives the title/artist and the song’s fact sheet. The request is made with YOUR key; it does not receive your identity.
• Genius, MusicBrainz, Wikipedia and Last.fm — receive the title/artist to return facts, context, critics’ reviews and the artist’s biography.
• Apple (iTunes) and Deezer — receive the title/artist to return the year, album and cover.
• LRCLIB — receives the title/artist to return synced lyrics (you can turn this off in Settings).
• Google — only for Sign in with Google and, on Android, Google Play for payments.
• Stripe — processes subscription payments on Windows.
• Microsoft (Edge) — turns the comment text into a free natural voice. If it is not available, the voice is generated on your own device: on Windows with Piper (its voices are downloaded once from Hugging Face, without sending any text) and on Android with the phone’s system voice.
• Voice services with your own key (ElevenLabs, Cartesia, Microsoft Azure, Google Cloud, Deepgram, or your AI provider’s voice: OpenAI, Gemini, Groq or Sarvam) — only if you turn them on; they receive the comment text to read it aloud.
• Our server (hosted on Render) — receives the title/artist to prepare song data, manages your plan and, on Android, acts as a bridge for the free natural voice (it receives the comment text to turn it into speech). It does not receive or keep your keys.

We do not sell your data or use it for advertising. Locutor does not collect usage statistics.

4. Transfers outside the European Economic Area

Some of these services are outside the European Economic Area (for example in the United States, China, India, Korea, Japan, Singapore or Brazil, depending on the AI or voice provider you choose). What they receive is the song information and the comment request, together with your connection’s IP address. These transfers happen because you choose that provider to serve you, and each one applies its own safeguards. If you prefer your data not to leave Europe, choose a European provider (for example Mistral) or a model on your own computer.

5. Purposes and legal basis

We process this data to provide the service you asked for (performance of the contract) and, where applicable, on the basis of your consent, which you can withdraw at any time by signing out or uninstalling the app.

6. How long it is kept

Server data is kept only as long as needed to provide the service and is reset frequently. Data stored on your device (your session, your hosts, your history, your keys) stays on your device until you sign out, delete it or uninstall the app. On Android it is not included in cloud backups.

7. Your rights

You can exercise your rights of access, rectification, erasure, objection, restriction and portability by writing to rfabregamiralbell@gmail.com. You can also complain to the data protection authority of your country (in Spain, the AEPD).

8. Children

Locutor is not directed at children under 14 and does not knowingly collect their data.

9. Changes

If we update this policy, we will change the date above and, if the change is important, show it in the app.
