Voice2Symbol is an AAC support app (Augmentative and Alternative Communication) that translates spoken language into Metacom symbols. We take the protection of your personal data very seriously and handle it confidentially in accordance with applicable data protection law (GDPR).
Purpose: Converting spoken language to text for symbol display
The app supports two modes: online speech recognition (via the Android SpeechRecognizer, which decides on-device whether to process online or offline) and offline speech recognition (fully local, no data transfer). In offline mode, no audio data is sent to external servers.
Data processed:
Legal basis: Art. 6(1)(b) GDPR (performance of a contract)
Data transfer: In online mode, audio is processed by the Android SpeechRecognizer. Whether and to what extent data is transmitted to Google servers is determined by the operating system and subject to Google's privacy policy.
Audio recordings are not stored permanently – automatically deleted after processing
Google privacy information:
Purpose: App functionality and personalisation
Data stored on your device:
| Data type | Purpose | Storage location |
|---|---|---|
| Custom word-symbol mappings | Personalisation | Local |
| Favourites list | Quick access | Local |
| Settings (colour schemes, etc.) | App configuration | Local |
| Debug logs (optional) | Error diagnosis | Local |
| Licence certificate | Licence verification without internet connection | Encrypted, local |
Important: This data does NOT leave your device and is automatically deleted when the app is uninstalled.
Purpose: Improving word-symbol mappings
Data processed (only when using the feedback system):
Legal basis: Art. 6(1)(f) GDPR (legitimate interest in app improvement)
Data transfer: Data is transmitted to voice2symbol.com and stored server-side.
Retention period: Until the feedback is processed, or up to 2 years
Voluntary: Use of the feedback system is entirely optional and can be disabled at any time.
The app queries our servers at startup to check whether relevant product information or notices are available for you as a user. These are displayed as short in-app messages and can be dismissed at any time by tapping "OK". Processing is based on our legitimate interest pursuant to Art. 6(1)(f) GDPR (informing about our own product features and updates). No data is shared with third parties.
Purpose: Responding to enquiries submitted via the contact form on voice2symbol.com
Data processed:
Legal basis: Art. 6(1)(b) GDPR (pre-contractual measures / handling your request)
Retention period: Until the enquiry is fully resolved, then deleted unless statutory retention obligations apply.
Sharing: Data is not shared with third parties.
Purpose: Translating recognised text into target languages for symbol display
The app uses Google ML Kit for the translation feature. All text processing happens entirely on-device – no entered or recognised text is sent to Google servers.
Google ML Kit periodically sends anonymous usage metrics (no personal data, no user content) to Google servers for quality assurance.
Translation models are downloaded once from Google servers on first use and stored locally thereafter.
Legal basis: Art. 6(1)(b) GDPR (performance of a contract)

Your payment data (card number, bank details) is transmitted directly to Stripe and is never stored on our servers.
