Cookie Policy

Version 2026-05-10

Effective date: May 10, 2026 Version: 2026-05-10

This Cookie Policy explains how Axevia Labs LLC, doing business as QuillAI ("QuillAI") uses cookies and similar technologies on quillhub.ai and related Services. It supplements the Privacy Policy.

1. What are cookies

A "cookie" is a small text file placed on your device (computer, tablet, phone) by a website. We also use related technologies such as localStorage, sessionStorage, and the IndexedDB browser API; for simplicity, this policy refers to all of these as "cookies".

2. Categories of cookies we use

We classify cookies into the following categories:

2.1 Strictly necessary

These cookies are required for the Service to function — for example, to authenticate you, remember your jurisdiction, prevent CSRF attacks, and provide core security. They cannot be disabled while you use the Service.

| Name | Purpose | Duration | Provider | |---|---|---|---| | sb-*-auth-token | Supabase authentication session | Session / up to 1 year | Supabase (first-party) | | qai_jur | User's legal jurisdiction (RU/EU/INTL) for routing legal documents | 30 days | QuillAI | | qai_country | ISO country code derived from IP for jurisdiction routing | 30 days | QuillAI | | qai_anon_id (localStorage) | Anonymous identifier for cookie-consent records | Until cleared | QuillAI | | qai_cookie_consent_v1 (localStorage) | Your cookie-consent decision | Until cleared | QuillAI | | NEXT_LOCALE | Selected language | 1 year | Next.js i18n (first-party) |

2.2 Analytics

We use PostHog (EU instance) to understand how the Service is used, identify usability issues, and prioritize improvements. PostHog sets cookies and uses localStorage to identify a session and aggregate behavior.

| Name | Purpose | Duration | Provider | |---|---|---|---| | ph_* | PostHog event tracking, feature flags | Up to 1 year | PostHog |

In the EU/UK/EEA/Switzerland, PostHog will not be loaded until you provide explicit consent through the cookie banner.

2.3 Error tracking

We use Sentry to capture and diagnose errors and crashes. Sentry is loaded for crash capture even before consent is given (it is essential to identify bugs that block your access to the Service), but personal identifiers and session-replay are disabled until you consent to analytics. Sentry's beforeSend hook strips user-identifying fields and cookies from error events when consent is absent.

2.4 Marketing

We currently do not set marketing or advertising cookies. If we add marketing-attribution cookies in the future, they will be subject to consent and listed in this policy with reasonable advance notice.

3. How to manage your cookies

3.1 In our cookie banner

When you first visit quillhub.ai, a cookie banner appears. The banner's behavior depends on your jurisdiction:

You can revisit your preferences at any time at Settings → Privacy → Reopen banner.

3.2 In your browser

Most browsers let you view, manage, and delete cookies through their settings. Disabling strictly-necessary cookies will prevent the Service from functioning correctly. Help pages:

3.3 Global Privacy Control

We currently do not honor the Global Privacy Control (GPC) signal automatically. If you wish to opt out of analytics, use the cookie banner directly. We expect to support GPC for California-resident users in a future update.

4. Third-party cookies

Our subprocessors may set their own cookies during interactions with their services, governed by their own privacy notices:

5. Changes to this policy

We may update this Cookie Policy from time to time. Material changes will be communicated through the cookie banner re-prompt and in-product messaging.
