Trust & Safety
Koydo Lingua serves children, families, schools, tutors, and adult learners. This page explains the protections that apply to accounts, messages, independent-tutor referrals, reviews, and AI-assisted practice in plain language.
Children's safety
AI tutor: 13 and up. Tutor lessons and classes: 16 and up. The AI tutor is for learners 13 and up. Joining a tutor or class by code, and lessons with tutors, are for learners 16 and older. Koydo does not currently offer or facilitate lessons for younger learners through Koydo.
Tutor background checks for teaching minors. Tutors whose marketplace profile or Koydo Lingua Teach Pro account indicates they teach under-18 students must hold a current verified background-screening badge before minor-facing bookings. The badge is visible on the tutor's profile once cleared. Tutors without a current badge cannot be searched by parents conducting an "under-13 student" search. Background checks expire annually and require re-running.
Every message is screened. When you message a tutor through Koydo, each message is checked before it's delivered. Messages that break our community guidelines are blocked. Messages that share a phone number or email address are flagged for our moderation team to review. You can report or block anyone, at any time.
Lesson recording. Lesson recording is not currently available.
Questions about a child's data or a lesson? Write to us at the contact address below and we will answer.
Data + privacy
Local processing where supported. Supported devices can handle routine practice locally. Features that need cloud processing identify that boundary before learner content is sent.
Cloud AI has learner privacy controls. When cloud processing is needed, Koydo applies its learner privacy and data-use controls. Provider and retention details belong in the current privacy and subprocessors disclosures.
A Data Processing Agreement for schools. A data processing agreement is available on request. Confirm any school-specific terms in the agreement itself.
Your data rights. You can ask to access, correct, delete or export your personal data by writing to privacy@koydo.app, and we will respond as the law requires.
Automated features
Some Lingua features use automated processing to support learning, such as pronunciation scoring and placement. They do not make admissions, grading or credential decisions on their own. To ask about an automated result, email privacy@koydo.app.
Tutor verification
Tutor profiles surface their verification level visibly to anyone searching the marketplace or considering hiring through Koydo Lingua Teach Pro:
Reviews + abuse
Reviews are never bought. Koydo never writes, seeds, or accepts payment for tutor reviews. A review can only come from a signed-in account with a completed booking with that tutor on Koydo — one review per booking, never anonymous.
Tutors get one response per review. Tutors can post a single public response to any review. No extended back-and-forth threads. Both review and response are subject to content moderation.
Reviews can be reported. If a review contains abusive language, personal information, or threats, report it and our team will look at it. Reviewers keep the right to share an honest opinion; we act on abuse, not on negative sentiment.
Report-abuse button on every profile, every message, every review. Reports are reviewed by our moderation team. Confirmed abuse → tutor warned, then suspended, then banned. Repeat student abusers similarly. Bans are permanent and the tutor's verified-tutor badge is revoked.
Lesson-payment boundary
Families and tutors agree on the lesson rate, cancellation and refund terms, and payment method directly. Koydo does not collect, hold, route, refund, reconcile, or pay out lesson funds and takes no percentage of tutor earnings. Koydo charges only for its own subscriptions, IAP, institutional software, and program-approved first-party products.
Accessibility + inclusion
WCAG 2.2 AA across every learner surface. Color contrast, keyboard navigation, screen reader semantics, focus management — all hold AA. AAA-grade where the cost is reasonable.
Reduce-motion respected. Atelier motion canon includes a reduce-motion fallback for every animation. prefers-reduced-motion halts everything except essential transitions.
Language depth stays visible. Tutor discovery, pronunciation tools, and lesson depth are labeled separately. Preview coverage is never presented as fully ready.
RTL languages full bidi support. Arabic, Hebrew, Persian, Urdu fully right-to-left including in the tutor dashboard, gradebook, parent share-links.
If something goes wrong
Email trust@koydo.app for any abuse report, safety concern, or content moderation question. For privacy and data requests, email privacy@koydo.app.
Critical safety concerns (suspected child endangerment, ongoing harassment, illegal activity) trigger immediate escalation. We cooperate with law enforcement requests received through proper legal channels.
