Your library. Your data.

ManwhaHaven is operated by Cameron Edwards. Contact beluga7whale@gmail.com about privacy or account data.

What we store and why

Account email, username and authentication records let you sign in. Saved titles, reading progress, ratings and settings provide your library and sync. Subscription identifiers and paid-through dates control paid access. We record the terms version accepted at registration and a short campaign source, if supplied, to understand how readers find us.

App release emails

We use your verified account email, or a separate release-email address you provide, to tell you when an Android update is available. Each email includes an unsubscribe link. Unsubscribing does not affect your account or in-app updates. We keep delivery records to avoid duplicate announcements and remove stored recipient addresses and message content from completed delivery records after 30 days.

Who processes it

Supabase hosts authentication and the application database in the project's EU region. OpenAI Sites and its hosting infrastructure serve the website. Resend processes email delivery when enabled. Lemon Squeezy processes subscription checkout and billing when you subscribe. ManwhaHaven does not receive full card details. These providers may process data internationally under their own service terms.

Visibility and local storage

New libraries are private by default. The account site stores sign-in tokens in your browser's session storage, cleared when you sign out. The reader app stores session, cached library and offline reading data locally. The public phone demo stores its sample library, favorites, ratings and preferences only in your browser; clearing site data in your browser removes those changes. It makes no database requests. Public reading sources may receive your IP address and requested image or page URLs. The website uses local assets and system fonts.

Marketing

We do not add you to a marketing mailing list just because you register. Emailing support is a direct support conversation, not automatic consent to newsletters. The site has no advertising pixels or cross-site analytics cookies.

Retention, export and deletion

Your library is kept while your account exists. Trial expiry does not immediately erase it. Export and account deletion are available from your account page; contact support if you cannot sign in. Deletion removes application records, while backups expire on the hosting provider's retention schedule. The billing provider may retain financial records required by law. Refund review and security records can be retained where necessary.

Your choices

You can request access, correction or deletion by email, and raise a concern with the relevant data protection authority. The trial is intended for adults aged 18 or older. We do not knowingly invite children's accounts.
