Privacy Policy

We collect information you provide directly, such as your email address, profile details, changelog subscription preferences, support messages, and account settings.

When you use Euangelion, we may process study activity such as notes, highlights, bookmarks, reading progress, saved preferences, and content interaction state so the product can work across sessions and devices.

We also collect limited technical information, including device, browser, log, and usage data, to keep the service reliable, secure, and understandable.

We use personal information to provide and improve Euangelion, sync study state, authenticate accounts, send requested release updates, respond to support requests, and protect the service.

We may use aggregate or de-identified information to understand product usage, prioritize improvements, and monitor reliability without identifying an individual user.

We do not sell personal information. We may share information with service providers that help us operate Euangelion, including hosting, authentication, analytics, email delivery, infrastructure, security, and support providers.

We may disclose information if required by law, to protect rights and safety, or to enforce our agreements and policies.

Euangelion may use cookies, local storage, and similar technologies to keep you signed in, remember preferences, measure usage, and improve performance.

You can control cookies through your browser settings, but some product features may not work correctly if required storage is disabled.

We keep personal information only as long as needed for the purposes described in this policy, unless a longer retention period is required for legal, security, backup, or legitimate operational reasons.

You may ask us to delete or update account-related information, subject to limitations such as security, fraud prevention, backup restoration, and legal requirements.

We use reasonable technical and organizational safeguards designed to protect personal information. No internet service can guarantee absolute security, so please use strong account credentials and contact us if you suspect unauthorized access.

You can unsubscribe from changelog emails through the email controls provided in those messages or by changing your account preferences where available.

You may contact us to request access, correction, deletion, or portability of personal information associated with your account.

Euangelion is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information, contact us so we can review and delete it when appropriate.

We may update this privacy policy as Euangelion changes. When we make material changes, we will update the last modified date and provide additional notice when appropriate.
