Privacy Policy

1. What we collect

We may collect account details, authentication data, subscription state, usage activity, learning progress, and technical logs needed to operate the service.

If you use AI-assisted features, your prompts and related output may be processed to deliver the requested experience and to maintain product quality and abuse protection.

2. Why we use data

Data is used to provide the product, authenticate users, enforce quotas and security controls, store learning progress, support subscriptions, and maintain service reliability.

3. Infrastructure and processors

Klio AI runs on production infrastructure that includes application servers, PostgreSQL, Redis, reverse proxying, and third-party providers used for DNS, hosting, or AI processing where applicable.

4. Security

We use transport encryption, authenticated API access, production security headers, segmented cache roles, and backup procedures to reduce operational risk. No system can be guaranteed perfectly secure.

5. Retention

We retain operational and account data for as long as needed to run the service, comply with legal obligations, resolve disputes, or enforce agreements.

6. Contact

For privacy-related requests, contact the service operator through the channel used for product support or account communication.
