Privacy Policy | Manacurve

Manacurve.gg ("Manacurve", "we", "us") is an independent Magic: The Gathering deck-building and analysis tool operated by Codecap Web Solutions. This policy explains what we collect, why, and what choices you have. If anything here is unclear, .

Information We Collect

Account information. When you create an account we store your email address, a hashed password (or third-party login identifier), and profile details you choose to provide. We use Supabase as our authentication and database provider.

Content you create. Decks, collections, comments, settings, and any other content you save are stored under your account so we can show it back to you across devices.

AI assistant (Loremaster) usage. Messages you send to the Loremaster are processed by Anthropic's Claude API to generate responses. We may retain your conversations to improve the product and debug issues.

Automatic information. Like most websites, our servers and third-party providers receive standard log data (IP address, browser type, referring page, timestamps) when you visit. This is used to operate and secure the site.

Cookies and Tracking

We use cookies and similar technologies. On your first visit we show a consent banner where you can accept or configure each category. You can change your choice at any time from the cookie settings link.

Necessary — required for authentication, CSRF protection, and core functionality. These cannot be disabled.
Functional — enable optional features such as embedded media and personalisation.
Performance — analytics and measurement so we can understand how the site is used and improve it.
Marketing — advertising and retargeting, including ad personalisation.

Anthropic — the Claude API powers the Loremaster assistant.
Google Analytics — usage analytics (loaded only with Performance consent).
Ahrefs Analytics — usage analytics (loaded only with Performance consent).

Legal Basis (EU/EEA Users)

Where the GDPR applies, we process personal data on the following bases: performance of a contract (operating your account), legitimate interests (security, product improvement), consent (non-essential cookies and marketing), and compliance with legal obligations.

Data Retention

We retain account and content data for as long as your account is active. If you delete your account, we delete or anonymise the associated personal data within a reasonable period, except where we must retain it to comply with legal obligations or resolve disputes. Backups are rotated on a standard schedule.

Your Rights

Depending on where you live, you may have the right to access, correct, export, or delete the personal data we hold about you, and to object to or restrict certain processing. To exercise any of these rights, . EU/EEA users may also lodge a complaint with their local data protection authority.

Children

Manacurve is not directed at children under 13, and we do not knowingly collect personal data from them. If you believe a child has provided us with personal data, contact us and we will delete it.

International Transfers

Our providers may process data outside your country, including in the United States. Where required, transfers are protected by Standard Contractual Clauses or equivalent safeguards.

Security

We use reasonable technical and organisational measures to protect your data, including encryption in transit, hashed passwords, and access controls. No system is perfectly secure, so we cannot guarantee absolute security.

Changes to This Policy

We may update this policy from time to time. Material changes will be reflected by updating the "Last updated" date above and, where appropriate, by a more prominent notice on the site.
