1. Data Controller

Voice2Symbol e.U.
Pottendorfer Straße 3/14, 1120 Wien, ÖSTERREICH
E-Mail: support@voice2symbol.com

2. General information on data processing

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).

Core principle: The app operates primarily locally on your device. Personal data (in particular voice recordings and, when using the feedback system, IP addresses) is processed solely for the purpose of app functionality. Most data remains local on your device.

3. Collection and storage of personal data

3.1 Speech recognition

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:

  • Audio recordings of your voice input
  • Timestamps of speech recognition events

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:

  • Google Cloud Privacy Policy: cloud.google.com/privacy
  • Speech-to-Text data usage: cloud.google.com/speech-to-text/docs/data-usage

3.2 Local data storage

Purpose: App functionality and personalisation

Data stored on your device:

Data typePurposeStorage location
Custom word-symbol mappingsPersonalisationLocal
Favourites listQuick accessLocal
Settings (colour schemes, etc.)App configurationLocal
Debug logs (optional)Error diagnosisLocal
Licence certificateLicence verification without internet connectionEncrypted, local

Important: This data does NOT leave your device and is automatically deleted when the app is uninstalled.

3.3 Optional feedback system

Purpose: Improving word-symbol mappings

Data processed (only when using the feedback system):

  • Reported word
  • Currently mapped symbol
  • Suggested symbol
  • Anonymised device ID
  • Timestamp of the report
  • IP address (anonymised)
  • App version

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.

3.4 In-App Notifications

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.

3.5 Contact form (website)

Purpose: Responding to enquiries submitted via the contact form on voice2symbol.com

Data processed:

  • Name
  • Email address
  • Subject and message content

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.

3.6 Translation feature (Google ML Kit)

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)

Further information: developers.google.com/ml-kit/terms

3.7 Account & Licence Data

Purpose: User account management, licence verification and device binding

Data processed:

  • E-mail address (login identifier)
  • Password (encrypted – original password is never stored)
  • Registration date and last login
  • Licence model, status and expiry date
  • Anonymised device fingerprint for licence binding — no personal device data is stored

Legal basis: Art. 6(1)(b) GDPR (performance of contract)

Retention: Account data is stored for the duration of the contractual relationship. After account deletion, data is erased within 30 days, except where statutory retention obligations apply (see section 3.8).

Access log (security): Login events, device activations and package downloads are logged with an anonymised IP address and timestamp, solely for security and abuse prevention.

3.8 Payment Data & Stripe

Purpose: Processing payments for licences

Payment processing is handled by Stripe Payments Europe, Ltd. (1 Grand Canal Street Lower, Grand Canal Dock, Dublin, D02 H210, Ireland), acting as a data processor pursuant to Art. 28 GDPR.
