The Privacy Problem with Language Learning Apps
Most language learning apps collect far more data than is necessary for their core function. What exactly is typically collected?
- Learning behavior: Which words you learned and when, how long you practice
- Content: Texts you enter are often used for AI training
- Device info: GPS, device ID, installed apps
- Usage profiles: When you open the app, how long you stay
- Ad data: Profile data for targeted advertising
This data is used to build user profiles — for advertising, for selling to third parties, for A/B testing. You pay with your data, even when the app is "free".
DopaSpeak collects none of this data
There are literally no servers that could receive your usage data. DopaSpeak is an Android app that runs locally on your device — without any backend connection for learning data.
On-Device AI: Why Local AI Is the Better Choice
DopaSpeak uses Google Gemma, an AI model that — after a one-time download — runs directly on your Android device. This is a fundamental difference from cloud AI services like ChatGPT or Google Translate.
Cloud AI vs. On-Device AI
- Cloud AI: Your text → Sent to server → Server processes → Response returned. Every input leaves your device.
- On-Device AI: Your text → Local model processes → Response stays on device. Nothing leaves your smartphone.
Benefits of On-Device AI
- Complete privacy — no data transfer to external servers
- Offline functionality — no internet needed (after model download)
- No latency — instant responses, no waiting for server response
- No per-request cost — on-device means unlimited AI usage
- Independence — no service can be shut down and disrupt your experience
GDPR, Data Protection, and DopaSpeak
The General Data Protection Regulation (GDPR) stipulates that personal data may only be processed with explicit consent and for legitimate purposes.
DopaSpeak has a radical answer to this requirement: We simply do not process personal data. There are no consent prompts because there is no data processing. There are no cookie banners because there are no cookies.
What DopaSpeak stores locally
Stored on your device:
- Your learning progress (which words/texts you have learned)
- Decoded materials (songs, texts)
- App settings and preferences
All of this stays on your device and is protected by your local Android data encryption.
Why Privacy Matters Especially in Language Learning
Language learning is an intimate activity. The texts you enter, the songs you learn, the languages you choose — all of this reveals a lot about you: your background, your interests, your communication partners.
Imagine you're learning Arabic for business communication with the Middle East. Or Russian for family reasons. In the wrong hands, this information could be used for profiling.
DopaSpeak is the only language learning assistant that guarantees: What you learn stays your secret.
