1. Who we are
This Privacy Policy explains how Kotlin Quest (the "App") handles personal data. The data controller is the person or entity identified in the app store listing and/or in-app legal notices.
2. Data we collect
• Account data: email, display name, profile photo if you add one, and authentication identifiers from your sign-in provider.
• Learning activity: progress, completed challenges, scores, streaks, preferences, and similar usage data.
• Device and diagnostics: app version, operating system, language, crash or performance logs, and security-related signals where needed to run and protect the service.
• Purchases: subscription status and transaction identifiers as provided by app stores or payment processors (we do not store full payment card numbers).
3. Purposes and legal bases
We use data to provide and improve the App, personalize learning, secure accounts, communicate about your account, comply with law, and analyze aggregate usage. Depending on your region, we rely on contract (providing the service), legitimate interests (security and improvement, balanced against your rights), consent where required, and legal obligation where applicable.
4. Sharing
We do not sell your personal data. We share data with service providers (hosting, analytics, authentication, customer support tools) under agreements that require appropriate protection. We may disclose information if required by law, to enforce our terms, or to protect rights, safety, and security. If the business is involved in a merger or acquisition, data may transfer subject to this Policy or equivalent protections.
5. International transfers
We may process data in countries other than yours. Where required, we use appropriate safeguards (such as standard contractual clauses) or rely on adequacy decisions.
6. Retention
We keep personal data only as long as needed for the purposes above, including security, dispute resolution, and legal compliance, then delete or anonymize it unless a longer period is required by law.
7. Security
We implement technical and organizational measures appropriate to the risk. No method of transmission or storage is completely secure; we cannot guarantee absolute security.
8. Your rights
Depending on your location, you may have rights to access, correct, delete, restrict, or object to processing, to data portability, and to withdraw consent where processing is consent-based. You may lodge a complaint with a supervisory authority. To exercise rights, use in-app tools where available or contact us as described in the App listing or this site.
9. Children
The App is not directed at children under 13 (or the minimum digital consent age in your region). We do not knowingly collect personal data from children below that age. If you believe we have, contact us and we will take appropriate steps.
10. Cookies and similar technologies
Mobile apps may use local storage and similar technologies for login sessions and preferences. Our websites, if any, may use cookies as described in any separate cookie notice.
11. Changes and contact
We may update this Policy and adjust the date above. Material changes may be communicated in the App where appropriate. For privacy requests, contact us through the App or store listing, or use the data deletion page linked from the App.
