Privacy Policy

Intersolution Trade Ltd. (“we,” “us,” or “our”) is the operator of Senthora, an AI–native language
tutor. We utilize a “Privacy by Design” framework, ensuring that AI–driven learning never
compromises your fundamental data rights. We adhere strictly to the GDPR (EU), the EU AI
Act, and COPPA (USA)

To provide real–time tutoring, Senthora transmits data to third–party Artificial Intelligence
providers. In accordance with Apple App Store Guideline 5.1.2(i) and the EU AI Act, we
explicitly identify our sub–processors:
• OpenAI, Inc. (GPT–4o mini & Realtime API): Processes text and audio for
conversational intelligence and fluency scoring.
• ElevenLabs Inc.: Processes text to generate synthetic voice responses.
• Google Firebase: Managed infrastructure for data hosting and secure
authentication.
• RevenueCat: Encrypted management of subscriptions and payment verification.
The “No–Training” Guarantee: We utilize Enterprise/API–tier agreements. Your private
conversations, text prompts, and voice recordings are NOT used by OpenAI, ElevenLabs, or
Intersolution Trade Ltd. to train foundation AI models.

A. Account & Identification Data
Name, email address, and account preferences collected via Firebase to maintain your learning
progress across devices.
B. Voice & Audio (Biometric–Derived Data)
When using “Voice Mode,” your audio is processed to analyze pronunciation, rhythm, and
fluency.
• Usage: This data is used strictly for linguistic inference (scoring), not for unique
biometric identification.
• Retention: Audio is temporarily cached for processing and deleted from sub–
processor volatile memory immediately after the tutor’s response is generated.
C. Learning History & Transcripts
We store transcripts of your AI interactions to provide grammar feedback, personalized lesson
paths, and “Streak” tracking.
D. Technical & Advertising Identifiers
We collect Device IDs (IDFA/AAID) and IP addresses via Firebase Analytics for app
optimization and marketing attribution. You can opt–out of “Tracking” in your device system
settings

As a Bulgarian entity, we comply with the EU AI Act (2026 Standards):
• AI Identification: You are always notified that you are interacting with a synthetic AI
system, not a human.
• Accuracy Disclaimer: AI systems may “hallucinate” or provide incorrect linguistic
feedback. Senthora is an educational aid, not a certified legal or medical translation
service.
• Right to Contest: You have the right to flag any AI output for manual review. Flagged
responses are reviewed by our human linguists to ensure safety and quality.

Senthora adheres to the UK Age Appropriate Design Code:
• Age Limit: Users must be 13 or older.

Economic Area) where possible
