Cookie Policy

Last updated: November 1, 2025

This Cookie Policy (this “Policy”) explains how Multi-AI Brainstorming SEIGETSU (“we,” “us,” or “our”) uses cookies and similar technologies on our website, application, and related services (collectively, the “Services”). This Policy forms part of our Privacy Policy.

1. What are cookies and similar technologies?

Cookies are small text files stored in your browser. They are used for purposes such as maintaining sessions, managing login state, and remembering site preferences (e.g., language).

In this Policy, “similar technologies” include localStorage / sessionStorage, pixel tags, web beacons, and privacy-preserving measurement scripts that do not employ fingerprinting. Depending on purpose, these are treated similarly to cookies (e.g., for consent, retention, and disclosure).

2. Types of cookies and similar technologies we use

Strictly Necessary Cookies Essential for core functionality (e.g., authentication, security, load balancing, CSRF protection, basic language preference). These cannot be opted out of within our consent tools. If you disable them in your browser, some features may not function properly.
- We issue CSRF cookies solely to protect requests. They are short‑lived, first‑party only, and not used for tracking. We do not store raw CSRF tokens in our database or logs.
- Authentication cookies are first‑party only and limited to service access. Access tokens are short‑lived; refresh tokens typically last up to 7 days.
Analytics Cookies and Similar Technologies (Opt-in) With your consent, we may use analytics tools (e.g., Google Analytics) to help improve the Services. Such tools may use cookies or similar technologies (e.g., first-party cookies, localStorage) to recognize returning visits and understand navigation.

If you do not consent, we may switch to privacy-preserving basic measurement that relies on non-identifying server logs or equivalent aggregated methods without persistent identifiers and without cross-site tracking or third-party advertising identifiers.

Note: We primarily use strictly necessary cookies. Analytics operate only with consent, consistent with our Privacy Policy.

Note for Canva app users: Our Canva extension that runs inside Canva does not set its own cookies or use WebStorage (such as localStorage or sessionStorage). Any cookies described in this Policy apply to our main website and standalone services.

3. How to give, manage, and withdraw consent

On your first visit (and periodically thereafter), we present a cookie consent banner to obtain your choices. You may use the core Services without consenting to analytics.
You can change or withdraw your consent at any time via the “Cookie Settings” link in the site or by reopening the consent banner. Withdrawal is effective moving forward and does not affect the lawfulness of processing based on consent before withdrawal.
You may also manage cookies in your browser; however, disabling strictly necessary cookies can impair functionality (e.g., login persistence).
Disabling strictly necessary cookies may prevent login and core functions from working.

4. Browser-level controls

Your browser settings let you refuse cookies, delete existing cookies, or set site-specific exceptions. See your browser’s help pages for instructions. If cookies are disabled, some features (including authentication) may not work properly.

5. Specific tools and retention information

Details about any analytics tools we use—including the provider, cookie names, purposes, and retention periods—are shown in the Details section of the consent banner or on the Cookie Settings screen. These listings may change if we update tools or configurations.
Payments: We use PayPal as our payments processor. Card numbers and other sensitive payment data are collected and stored directly by PayPal; we do not store such data. See our Privacy Policy (and PayPal’s privacy policy) for more information.
We do not share raw authentication cookies/tokens with third parties. Where token identifiers must be processed for security, we use hashed identifiers and limit use strictly to security purposes.
Strictly necessary cookies (examples and retention): session, CSRF, and authentication cookies are used only for core functions and retained for session or short durations (e.g., hours to days). They are not used for analytics or advertising.

6. Relationship to personal data

Where information collected via cookies or similar technologies constitutes personal data, we process it in accordance with our Privacy Policy. Analytics processing is based on your consent (opt-in). Basic, non-identifying aggregated measurement may rely on our legitimate interests (e.g., service quality and security), subject to applicable law. Strictly necessary cookies are processed under legitimate interests or contract performance. We do not employ fingerprinting techniques.

7. Changes to this Policy

We may update this Policy as needed. We will post updates on this page and, for material changes, reflect them in the consent banner / Cookie Settings experience.
