Privacy Policy — Text to Speech

Android app · Last updated: 11 May 2026

This Privacy Policy describes how the Text to Speech Android application ("the App", "we", "us") handles information when you use it. By installing or using the App, you agree to the practices described below.

1. Summary

• By default the App generates speech using your device's built-in Android Text-to-Speech engine — everything happens on your device with no network.
• If you choose to enter an ElevenLabs API key in Settings, the App will send the text you type to ElevenLabs' servers so it can return higher-quality voices. This is opt-in.
• The App fetches small avatar images for voices from a public CDN. No personal data is sent.
• We do not operate a backend server for this App. We do not show ads, and the App includes no analytics or crash-reporting SDKs.

2. What the App does on your device

• Converts typed text to spoken audio using the on-device Android TTS engine.
• Adjusts speech speed, pitch, and selected voice.
• Plays audio with lock-screen and notification playback controls (pause, resume, seek).
• Imports text from PDF, DOCX, and image (OCR) files that you select via the system file picker. All extraction runs on-device.
• Saves your generated voiceovers to a personal library so you can re-play, mark as favorite, or share them later.
• Optionally saves the generated audio as a .wav file to your device's documents directory and lets you share it via the Android share sheet.

3. Network calls

3.1 ElevenLabs (only if you opt in)

The App can optionally use the ElevenLabs cloud text-to-speech service to generate higher-quality voices. This is off by default. To turn it on, you must paste your own ElevenLabs API key into the App's Settings.

While ElevenLabs is enabled, the App calls these endpoints over HTTPS:

• GET https://api.elevenlabs.io/v1/voices — to fetch the list of voices available to your account.
• POST https://api.elevenlabs.io/v1/text-to-speech/<voiceId> — to convert the text you typed into audio. The text you submit is sent to ElevenLabs along with your API key.

Your ElevenLabs API key is stored on your device in Android local storage (AsyncStorage) under the key @eleven_api_key. It is not transmitted to anyone except ElevenLabs.

3.2 Avatar images (always, but no personal data)

The App requests small avatar images for the voices shown on the home, compose, and voice-list screens from https://api.dicebear.com/9.x/avataaars (the public Dicebear avatar generator). The request contains only the voice name as a seed; no personal information about you is sent.

3.3 No other network calls

The App does not operate a backend of its own. Aside from ElevenLabs (opt-in) and the Dicebear avatar CDN, the App does not transmit any data over the internet. The Android system TTS engine may, independently of the App, download voice packs over the internet; that traffic is managed by your device's TTS engine and not by us.

4. Data stored on your device

The App stores the following items in local storage (AsyncStorage) on your device. None of this leaves your device, except as noted in section 3.

• Library — the voiceovers you create: title, the text used, voice ID, language/accent, tags, playback progress, duration, favorite flag, downloaded flag, created timestamp.
• Settings — theme, accent color, language, speech speed, high-quality audio flag, background playback toggle, default voice, favorite voice IDs.
• Local profile — a display name and email kept entirely on your device (no account is created on any server we operate). Used only to personalize the UI.
• ElevenLabs API key — only if you chose to enter one (see section 3.1).

Audio files you explicitly save via "Download" are written to your device's documents directory at audio/<name>-<timestamp>.wav. Files saved or shared this way remain on your device until you delete them yourself.

5. Document import

When you import a PDF, DOCX, or image file, the App uses your device's system file picker and parses the file content on-device. The file content is then loaded into the compose screen so you can review and generate speech from it. The original file is not copied to a server. If ElevenLabs is enabled and you generate speech from imported text, the text you generate from will be sent to ElevenLabs as described in section 3.1.

6. Android permissions

The App declares the following permissions:

• INTERNET — used for the optional ElevenLabs calls and the Dicebear avatar CDN. Not used for any other purpose by the App.
• POST_NOTIFICATIONS — to show the playback-control notification while audio is playing.
• FOREGROUND_SERVICE — to keep audio playing reliably when the App is in the background and to power the lock-screen media controls.

The App does not request the microphone, camera, location, contacts, or any other sensitive permission. File access is mediated by the Android system file picker only when you tap "Import".

7. Third-party services and libraries

• react-native-tts — bridge to your device's Android Text-to-Speech engine. Runs on-device.
• ElevenLabs API — optional cloud TTS, only when you opt in by entering an API key (section 3.1).
• Dicebear avatar CDN — fetches voice avatar images (section 3.2). No personal data sent.
• react-native-document-picker, react-native-fs, react-native-share — local file I/O, no telemetry.
• Standard React Native libraries (state management, UI, navigation, etc.) — no analytics found.

The App contains no third-party advertising, analytics, or crash-reporting SDKs. Distribution is via Google Play, governed by Google's own privacy policy.

8. Children's privacy

The App is suitable for all ages. We do not knowingly collect personal information from children under 13. If you choose to enable ElevenLabs, please review their policy regarding minors.

9. Data security

When ElevenLabs is enabled, communication with their service uses HTTPS/TLS. The Dicebear avatar CDN is also accessed over HTTPS. Your ElevenLabs API key and your library are stored in standard Android local storage on your device.

10. Changes to this policy

If we materially change this Privacy Policy, we will update the "Last updated" date at the top of this page.
