Privacy Policy

May 4th, 2026

This Privacy Policy describes how rmsaraiva.com collects, uses, and protects the personal data of users who access this site and its hosted services, in compliance with the Brazilian General Data Protection Law (LGPD — Law No. 13,709/2018).

1. Data controller

The data controller for your personal information is Rodolfo Motta Saraiva, responsible for rmsaraiva.com. To exercise your rights or clarify any questions, contact us at .

2. Data collected

We collect only the data strictly necessary to provide our services:

  • Account data (via Google login): When you sign in with Google, we receive your full name, email address, profile picture, and unique Google identifier (Google ID). This data is collected exclusively with your explicit consent when you authorize the login.
  • Leaderboard data (Arkanolf): If you choose to save your score on the Arkanolf public leaderboard, we store your chosen player name, score, level, and submission date.
  • AI-based name moderation (Arkanolf): When you choose a public name for the Arkanolf leaderboard, that name is sent to external Artificial Intelligence services (Google Gemini and/or OpenRouter) to verify it is appropriate for a general audience. Only the name itself is transmitted; no other personal information is shared in this process.
  • Usage data (Google Analytics): We use Google Analytics to collect anonymous, aggregated data about site usage — pages visited, session duration, device type, and approximate country-level location. This data does not allow personal identification.
  • Contact form data: If you fill out the contact form, we collect your name, email, and message in order to respond to your request.

3. Purpose of data use

Collected data is used to:

  • Authenticate your identity and maintain your logged-in session in services that require authentication.
  • Display your name and profile picture in the interface of authenticated applications.
  • Record and display scores on the Arkanolf public leaderboard.
  • Respond to messages sent via the contact form.
  • Analyze anonymous site usage to improve content and user experience.
  • Marketing communications (optional): Your email address may be used to send news, releases, and promotions about the site and its games/applications/books, only if you explicitly consent through an opt-in subscription. Consent can be withdrawn at any time via the unsubscribe link in any email or by contacting us.

4. Data sharing

Your personal data is not sold, rented, or shared with third parties for commercial purposes. The only sharing occurs with essential service providers:

  • Google LLC: Provider of the OAuth login service and analytics tool (Google Analytics). Data shared with Google is governed by Google's Privacy Policy.
  • Google Gemini / OpenRouter: AI services used to moderate Arkanolf player names. The name you type is sent to these providers solely for content verification. See the privacy policies of Google Gemini and OpenRouter.
  • Formspree: Service used to process contact form submissions. Your message is forwarded via Formspree to our email.

5. Data retention

Account data is retained for as long as your account exists and the services are active. Leaderboard data (Arkanolf) is retained indefinitely to maintain the public ranking. You may request deletion of your data at any time by contacting us.

6. Your rights (LGPD)

Under the Brazilian General Data Protection Law (LGPD), you have the right to:

  • Confirmation and access: Know whether we process your data and obtain a copy of it.
  • Correction: Request correction of incomplete, inaccurate, or outdated data.
  • Deletion: Request deletion of your personal data processed on the basis of your consent.
  • Withdrawal of consent: Revoke your consent to data processing at any time, which does not affect the legality of processing carried out before the withdrawal.
  • Portability: Request portability of your data to another service provider.
  • To exercise any of these rights, contact us at .

7. Cookies

This site uses cookies and similar technologies to:

  • Session cookies: Required to keep you authenticated during your visit.
  • Analytics cookies (Google Analytics): Collect anonymous usage data for analytical purposes. You can disable them using tracker-blocking extensions or your browser settings.
  • Arkanolf cookies: When playing Arkanolf, the game uses cookies and localStorage to save game preferences, level progress, personal best scores, and login session data.
  • This site does not use cookies for advertising or third-party behavioral tracking.

8. Security

We adopt appropriate technical and organizational measures to protect your data against unauthorized access, loss, alteration, or improper disclosure. Authentication is handled entirely by Google, meaning your credentials (password) never pass through our servers.

9. Changes to this policy

This policy may be updated at any time. The "last updated" date at the top of this page reflects the most recent version. We recommend reviewing it periodically.
