Cookie Policy
Version: 1.2.0 · Last updated: 2026-10-28
Prismatica uses two cookies, both for sign-in and features you use, and stores preferences in your browser's local storage. It has no analytics or marketing scripts: the consent banner only records your choice.
| Name | Type | Purpose | Lifetime | Consent required? |
|---|---|---|---|---|
| prismatica_refresh | Cookie (HttpOnly, sent only to the sign-in service) | Keeps you signed in by renewing your session. | 30 days, or until you sign out. | No, strictly necessary for sign-in. |
| osio_ide_preview | Cookie (HttpOnly, workspace code preview only) | Authorises the preview of your workspace code sandbox. | 1 hour. | No, strictly necessary for that feature. |
| prismatica-theme | localStorage | Stores light, dark or night interface preference. | Until cleared or changed. | No, strictly necessary preference. |
| prismatica-motion-paused | localStorage | Stores reduced motion preference for accessibility. | Until cleared or changed. | No, accessibility preference. |
| prismatica-consent-v1 | localStorage | Stores consent choices, timestamp and policy version. | 6 months, or until this policy changes; you are then asked again. | No for storing proof of choice; optional categories require consent. |
| prismatica-newsletter-intent-v1 | localStorage | Stores unauthenticated newsletter opt-in intent until login sync. | Until sync or manual clearing. | Yes, newsletter consent. |
| prismatica-csrf-token-v1 | localStorage | Stores a CSRF nonce for the public data-rights form. | Until cleared. | No, security necessity. |
| osio:* and osionos* keys | localStorage (workspace) | Your signed-in workspace session, a cache of your pages, favourites, contacts, unread counts and pending edits, and workspace settings. | Until cleared. | No, strictly necessary for the workspace. |
You can change or withdraw your choices at any time with the button below or the "Cookie settings" link in the site footer. Rejecting optional categories never limits access to the site.
