Privacy Policy

Information we process

DYSHEA may process your email address, learner profile name, public nickname, AI tutor messages, purchase details, technical identifiers, course progress, placement result, learning goals, XP, streak, league activity, classroom or family membership and feedback you submit. Account passwords are stored only as salted cryptographic hashes, not as readable passwords.

Payments

Payments are processed by PayPal or Gumroad. DYSHEA does not receive or store full card numbers. The selected provider may process payment, billing, tax and fraud-prevention information under its own privacy terms. DYSHEA receives limited transaction details needed to provide and manage access.

AI tutor

Messages sent to Dyshi AI may be transmitted to our AI service provider to generate a response. Do not include passwords, payment details or other sensitive personal information in tutor messages.

Feedback and testimonials

Feedback is private by default. We publish a comment with the learner's public nickname only when the learner separately consents and the owner approves it. Email addresses are never included in public testimonials. You may withdraw publication consent by contacting us.

How we use information

• Provide lessons, purchases, certificates and support.
• Prevent abuse, enforce usage limits and operate the Arena leaderboard.
• Improve reliability and understand registration, activation, learning and purchase funnels.
• Send service, invitation, security or optional weekly progress messages you requested.

Family and classroom visibility

A Family subscription owner can see the nicknames, account emails and learning totals of learners occupying their subscription seats. A Schools teacher can see invited students' nicknames, account emails, XP, streak and completed-step totals. Other learners do not receive access to private account email addresses. Leave or removal from a group ends this shared visibility.

Storage and retention

Signed-in learner progress is stored with the account so it can be used across devices. A local browser copy may also be kept for continuity and migration. Purchase and service records may be retained as needed for access, support, accounting, fraud prevention and legal obligations.

Children and guardians

If local law requires parental or guardian consent for a learner to use online services, that consent must be obtained before using DYSHEA or making a purchase.

Your choices

You may request access, correction or deletion of information associated with your email, subject to applicable law and records we must retain. Contact dyshea@dyshea.com.
