Cookie Policy
Effective date: May 11, 2026
This Cookie Policy explains how BttrLabs Private Limited(“Watari”) uses cookies and similar technologies when you visit our marketing site or use the Watari application. It supplements our Privacy Policy.
1. What are cookies?
Cookies are small text files stored on your device when you visit a website. They allow the site to recognise your device across pages and across visits, and to store small pieces of state — such as whether you are signed in.
We also use related technologies such as localStorage, sessionStorage, and pixel tags. References to “cookies” in this Policy include those technologies.
2. Categories we use
- Strictly necessary cookies are required for the Service to function (e.g. authentication, session continuity). These cannot be turned off without breaking core functionality. They do not require consent under EU ePrivacy / DPDP frameworks.
- Functional cookies remember preferences such as theme and side-bar state to make the Service more usable. They do not track behaviour across sites.
- Analytics cookies help us understand aggregate usage patterns so we can improve the Service. We use these only after you grant consent in jurisdictions that require it (EU, UK, EEA, Switzerland).
We do not currently use any cookies for cross-context behavioural advertising, retargeting, or sale of personal information.
3. Cookies in detail
| Name | Source | Category | Purpose | Duration | Party |
|---|---|---|---|---|---|
sb-*-auth-token | Supabase Auth | Strictly necessary | Keeps you signed in. Used to authenticate your session. | Session + 7-day refresh | first-party |
sidebar_state | Watari app | Functional | Remembers whether the dashboard side-bar is collapsed or expanded. | 7 days | first-party |
watari_consent | Watari app (cookie banner) | Strictly necessary | Records your cookie-consent decision so the banner does not re-prompt on every visit. Set only after you click Accept or Reject on the banner. | 1 year | first-party |
__vercel_live_token | Vercel | Strictly necessary | Preview-deployment authentication. Set on preview URLs only — not present on the production site. | Session | third-party |
3a. localStorage entries
A few preferences are stored in your browser's localStorage rather than in cookies. These are read by client-side JavaScript only and are not transmitted to our servers on every request.
theme— Remembers your dark- or light-mode preference. Stored in browser localStorage by next-themes, not in a cookie.watari_consent— Mirror of the cookie above. localStorage version is read by the consent helper to gate analytics; cookie version is read by future server-rendered analytics loaders.
3b. Analytics — not yet wired
Watari plans to wire PostHog (ph_* cookies) for product analytics. The SDK is not yet installed; no analytics cookies are currently set. When it ships, PostHog will load only after you grant analytics consent on the banner, and this page will be updated with the specific cookies set.
4. Consent & controls
When you first visit the marketing site from a region that requires cookie consent (EU, UK, EEA, Switzerland), a banner will ask you to Accept or Reject non-essential cookies, or to customise your choices. We default-deny all non-essential categories until you make a choice. Your preference is stored on-device and respected on future visits.
You can change your preferences at any time by clicking “Cookie settings” in the site footer.
We honour the Global Privacy Control (GPC) signal — if your browser sends GPC, we treat that as an opt-out of analytics cookies (and, where applicable, of any “sale” or “share” for cross-context behavioural advertising).
You can also block or delete cookies directly via your browser settings. Note that blocking strictly necessary cookies may break the Service.
5. Third-party cookies
Third parties listed in the table above process cookie data under their own privacy policies, summarised at watari.ai/legal/subprocessors.
6. Changes
We may update this Cookie Policy from time to time. The “Effective date” at the top of this page indicates the last revision. Material changes are notified by email to the registered owner of each Organisation at least 30 days before they take effect.
