Indicator Design Studio Cookie Policy

Last Updated: 2026-05-19

Version: cookie-v1.0-beta

This Cookie Policy explains how Indicator Design Studio uses cookies and similar technologies.

1. What Are Cookies

Cookies are small text files stored on your device by websites/apps.

We also use similar technologies (local storage, session storage, SDK/device identifiers) where relevant.

2. Categories of Cookies

A. Strictly Necessary Cookies

Used for:

1. authentication/session continuity;
2. security and abuse prevention;
3. core platform functionality.

These are required for the Platform to operate.

Current strictly necessary authentication cookie (web app):

• `web3_refresh_token` (name may vary by environment configuration):
• purpose: secure refresh-session continuity for Web3 authentication;
• type: `HttpOnly`, `Secure` (production), `SameSite` (default `Lax`);
• path: authentication scope (default `/api/auth`);
• access: not readable by JavaScript runtime;
• retention: persistent, up to configured refresh-token lifetime (default up to 30 days), or earlier on logout/revocation.

B. Functional Cookies

Used for:

1. language and interface preferences;
2. UX continuity settings;
3. non-essential but useful product behavior.

C. Analytics Cookies

Used for:

1. understanding feature usage;
2. performance diagnostics;
3. improving product quality.

These may require consent in certain jurisdictions.

D. Marketing/Advertising Cookies

If enabled in future, these may be used for campaign measurement and attribution.

Where legally required, they will be off by default until consent is granted.

3. Third-Party Technologies

We may use third-party providers for analytics, error tracking, infrastructure monitoring, and support tooling.

Those providers may set their own cookies or identifiers under their own policies.

4. Legal Basis

Where GDPR/ePrivacy rules apply:

1. strictly necessary cookies are processed under legitimate interest/contract necessity;
2. non-essential cookies are processed based on user consent where required.

5. Managing Preferences

You can manage cookie preferences by:

1. in-product cookie controls (when available);
2. browser settings (block/delete cookies);
3. clearing site storage.

Blocking required cookies may break core Platform functionality.

6. Retention

Cookie lifetimes vary by type:

1. session cookies expire when your session ends;
2. persistent cookies remain until expiry or deletion;
3. analytics identifiers may rotate by policy.

For authentication continuity, the refresh cookie lifetime is tied to backend security configuration and may be invalidated early due to logout, token rotation, or security revocation.

7. Changes

We may update this Cookie Policy from time to time.

Updated versions become effective when published.

8. Contact

For cookie/privacy requests, use the official support/legal channels published in the Platform.
