1.What is a cookie?
A cookie is a small text file stored on your device when you visit a website. We also use related technologies such as localStorage and pixel tags. In this policy we refer to all of these as “cookies”.
2.Categories we use
- Strictly necessary — required for the Platform to function (authentication, security, consent storage). These cannot be disabled.
- Functional — remember preferences such as theme. Disabling them won't break the site but will reset your settings.
- Analytics — help us understand how the Platform is used so we can improve it. Set only with your consent in jurisdictions where consent is required.
- Marketing — we currently do not set marketing or advertising cookies. If we introduce them, we'll update this policy and request consent first.
3.Cookies we set
| Name | Purpose | Category | Duration |
|---|---|---|---|
| sb-access-token | Authenticates your session. | Strictly necessary | 1 hour (rotates) |
| sb-refresh-token | Renews your session without re-login. | Strictly necessary | 30 days |
| tc_consent | Stores your cookie-consent choices. | Strictly necessary | 12 months |
| tc_theme | Remembers your light/dark theme preference. | Functional | 12 months |
| _ga / _ga_* | Google Analytics — anonymised usage measurement (set only if you accept analytics). | Analytics | Up to 24 months |
4.Third-party services
Some cookies are set by third parties we use to operate the Platform — currently Supabase (authentication) and, where you consent, Google Analytics. These providers are bound by their own privacy policies. We do not share personally identifiable information with advertising networks.
5.Controlling cookies
You can control cookies in three ways:
- Consent banner — when we launch analytics in your region, a banner will let you accept or reject non-essential cookies.
- Browser settings — most browsers let you block or delete cookies. Doing so for strictly necessary cookies will sign you out and may break parts of the Platform.
- Do Not Track — we honour the GPC (Global Privacy Control) signal where it is legally recognised.
6.Changes to this policy
We will update this Cookie Policy when our cookie use changes. The effective date at the top of this page reflects the most recent revision.
