Privacy Policy
Last updated: October 7, 2026
The Short Version
- AI features: When you use voice transcription, topic-based article generation, or AI article cleanup, the audio or text needed for that request is sent to our AI providers. We ask for your explicit consent before that data is sent.
- Free users: Outside of AI feature requests, your reading content, progress, and quiz scores stay on your device only.
- Paid users: Outside of AI feature requests, we sync your content and progress to our servers so you can access it across devices.
- App lock: Optional. What it uses stays on your device.
- We never sell your data. We use third party services for authentication, payments, AI features, and potentially analytics. Each has its own privacy practices.
1. Information We Collect
Information You Provide
Account Information
When you sign in with Google or Apple, we receive your email address and display name from those services. We do not store passwords. Authentication is handled entirely by Google or Apple.
Content You Import (Paid Users)
If you subscribe to Devoro Premium, we store the content you import (URLs, PDFs, EPUBs, text) on our servers to enable multi device sync. If you choose to use AI article cleanup, the article text needed for that request is sent to our AI providers after we ask for your explicit consent. This stored sync data includes:
- Imported articles and documents
- AI generated articles you create
- Reading progress and history
- Quiz scores and certifications
Content You Import (Free Users)
If you use Devoro for free, your imported content, reading progress, and quiz scores are stored locally on your device only. If you choose to use voice transcription or topic-based article generation, the text or audio needed for that request is sent to our AI providers after we ask for your explicit consent. We otherwise do not have access to your local-only reading data.
Information Collected Automatically
Device Identifiers
We generate an anonymous user ID to operate the app. This ID is not linked to your personal identity unless you create an account.
Usage Analytics (Future)
We may implement analytics to understand how the app is used. If we do, we will use privacy respecting tools and update this policy accordingly.
2. How We Use Your Information
- Provide and maintain the Devoro service
- Sync your content across devices (paid users)
- Process AI feature requests, including voice transcription, topic-based article generation, and AI article cleanup
- Process subscription payments
- Respond to support requests
- Improve the app based on aggregated, anonymized usage patterns
We do not sell your personal data, use your content to train AI models, or share your reading habits with advertisers.
3. Third Party Services
Devoro uses the following third party services:
When you request an AI feature, we send only the data needed to fulfill that request after we ask for your explicit consent. This can include a voice recording for transcription, a topic or custom learning prompt for topic-based article generation, or imported article text for AI article cleanup. We do not send your synced reading history, quiz scores, or broader imported library to AI providers.
AI-Powered Features
Devoro uses named third-party AI providers for specific feature requests: OpenAI (Whisper) for voice transcription, Google (Gemini) and/or Anthropic (Claude) for topic-based article generation, and Google (Gemini) for AI article cleanup.
We send only the audio or text needed to fulfill your request, and we ask for your explicit consent before that data is sent. Provider handling follows each provider's privacy policy.
App lock (optional)
App lock is off unless you switch it on (Settings, “Lock apps until I hit it”). It keeps the apps you choose closed until you meet your daily reading goal.
On iPhone and iPad it uses Apple’s Screen Time framework (Family Controls). The apps you pick (and, with Premium, categories or websites) are stored by iOS as tokens that Devoro cannot read as names, and they stay on your device.
On Android it uses the Accessibility service only to notice which app has just opened (window changes), so Devoro can show its “Read first” screen. It never reads what is on your screen, what you type or any content, and it does not perform actions for you. To let you pick apps, Devoro lists the apps installed on your phone (names and icons). That list stays on your device and is never sent to us.
Nothing about App lock (your chosen apps, schedules, lock settings, or when apps were opened) is ever sent to us, shared or used for analytics. It stays on your device and is not synced. You can turn App lock off or revoke the permission at any time, and it stops.
4. Data Storage and Security
Where We Store Data
Our servers are located in the European Union (via Supabase's EU infrastructure). We may add additional server locations in the future to improve performance.
How We Protect Data
We use industry standard security measures including:
- Encrypted data transmission (TLS/SSL)
- Encrypted data storage at rest
- Secure authentication via OAuth 2.0
- Regular security updates
While we implement reasonable safeguards, no system is 100% secure. We cannot guarantee absolute security of your data.
5. Your Rights (GDPR)
If you are in the European Economic Area (EEA), you have the right to:
- Access your personal data
- Correct inaccurate data
- Delete your data (right to be forgotten)
- Export your data in a portable format
- Object to certain processing
- Withdraw consent at any time
To exercise these rights, contact us at [email protected]. We will respond within 30 days.
Data Retention
- We retain your data as long as your account is active
- Upon account deletion, we delete your personal data within 30 days
- We may retain anonymized, aggregated data for analytics purposes
6. Children's Privacy
Devoro is not intended for children under 13 years of age. We do not knowingly collect personal information from children under 13. If you believe we have collected data from a child under 13, please contact us immediately at [email protected] and we will delete it.
7. Changes to This Policy
We may update this Privacy Policy from time to time. When we make significant changes, we will:
- Update the "Last updated" date at the top
- Notify you through the app or via email
Your continued use of Devoro after changes take effect constitutes acceptance of the updated policy.
