Cookie Policy

EFFECTIVE DATE: 29 MAY 2026  ·  LAST UPDATED: 29 MAY 2026

What this covers

This page explains what cookies and similar technologies (localStorage, sessionStorage) Kōda OS uses, why we use them, and how you can control them. It supplements our Privacy Policy.

What are cookies?

Cookies are small text files stored by your browser when you visit a website. We also use browser storage APIs (localStorage and sessionStorage) for the same purpose. Throughout this policy "cookies" refers to all of these.

Essential cookies

These are required for Kōda OS to work. They cannot be turned off. They store authentication tokens, your preferences, and your in-app data while you use the service.

NamePurposeDuration
sb-*Supabase Auth — keeps you signed inSession / persistent
koda_* (localStorage)Profile cache, UI preferences, draft trades, tour progressPersistent until cleared
koda_cookie_consentRemembers your choice on this bannerPersistent until cleared
koda_beta_unlockedRemembers your beta access codePersistent until cleared

Analytics cookies (require consent)

If you click "Accept" on the cookie banner, we load PostHog to understand how Kōda is used in aggregate. Analytics help us improve the product. They are not used for advertising and we do not sell this data.

NameProviderPurposeDuration
ph_*PostHogAggregate usage analytics, feature performance, anonymous session replay (passwords masked)Up to 1 year

If you click "Reject", PostHog is never loaded.

Error monitoring

We use Sentry to capture application errors so we can fix bugs. Sentry runs only when an error occurs, does not set cookies, and does not collect personal information beyond the error context (URL, browser version, stack trace). We consider this a necessary part of running a reliable service. See the Sentry Privacy Policy.

Third-party cookies

Stripe sets cookies on the Stripe-hosted checkout page when you subscribe to Pro. Those cookies are required for payment processing and are governed by Stripe's Privacy Policy. We do not set Stripe cookies on Kōda pages.

How to change your choice

You can change your decision at any time:

We're adding a Cookie preferences screen to Settings — once live, you'll be able to change your choice in-app.

Do Not Track

Kōda OS honours your explicit consent choice. We treat browser "Do Not Track" signals as advisory only; the banner choice is authoritative.

Changes to this policy

If the cookies we use materially change, we'll update this page and re-prompt for consent.
