Cookie Policy
Effective date: 8 December, 2025
Last updated: 4 July 2026
This website and the Nadi app are operated by Braw Impact Ltd, trading as Nadi (registered in Scotland, company number SC822663).
1. What are cookies?
This Cookie Policy explains what cookies are, how Nadi uses them, the types of cookies we use, and how you can manage your cookie settings. Cookies are small text files stored on your device when you visit a website. They help the site function properly, improve security, support features, enhance user experience, and allow us to understand website performance. Cookies used on our public website are different from the way the Nadi app, our secure, login-only space, keeps you signed in.
2. How we use cookies?
We use both first-party cookies (set by Nadi) and third-party cookies (set by services we use). We use cookies to:
- operate the website securely
- remember your cookie consent preferences
- understand how visitors use our website (only with your consent)
- support embedded features, such as our newsletter sign-up form
Analytics cookies only load after you give consent through the cookie banner, and you can withdraw that consent at any time. We do not currently use any marketing cookies.
3. Cookies on the public website (nadi.health)
A. Necessary Cookies (always active)
These cookies support consent management. They do not store personal information for advertising or tracking purposes.
| Cookie | Duration | Purpose |
|---|---|---|
| cookieyes-consent | 1 year | Set by CookieYes, our consent management tool. Stores your cookie consent preferences. |
B. Embedded content
Our newsletter sign-up form is provided by EmailOctopus inside an embedded form. EmailOctopus may set its own cookies to make the form work. These are governed by EmailOctopus’s own privacy and cookie policies.
C. Analytics Cookies (consent required)
We use Google Analytics to understand how our website is used. These cookies are set only after you accept analytics cookies in the banner, and you can withdraw that consent at any time via the cookie banner (the CookieYes icon on the site).
| Cookie | Duration | Purpose |
|---|---|---|
| _ga | 13 months (browser maximum) | Used by Google Analytics to distinguish visitors. |
| _ga_N8YDQBYYCB | 13 months (browser maximum) | Used by Google Analytics to maintain session state. |
D. Marketing Cookies
We do not currently set any marketing cookies on nadi.health. If that changes, we will update this policy and such cookies will only load after you give consent.
4. How the Nadi app (my.nadi.health) keeps you signed in
The Nadi app (my.nadi.health) is a private, secure, login-only space where users see their estimated cycle phases mapped into their calendar. Because these functions require authentication, the app needs to maintain a secure session once you sign in.
Rather than cookies, the Nadi app keeps you signed in using a single entry in your browser’s local storage, which holds your session tokens. It is created when you sign in, removed when you sign out, and never used for tracking or advertising.
This entry is essential for securing your account and protecting any sensitive health information you choose to add to Nadi.
5. Sensitive data within the Nadi app
The Nadi app may process health-related information that you enter or that we calculate for you, such as:
- cycle length and period length
- period start dates
- your cycle phase estimates
This information is never stored in cookies.
It is stored securely in our database (Supabase) with strict access and encryption controls. A full explanation of how we protect health data appears in our Privacy Policy.
6. International data transfers
Some third-party providers (such as Google Analytics, Vercel, CookieYes, and EmailOctopus) may process data outside your country, including in the United States. When this occurs, we ensure appropriate safeguards are in place as required under UK GDPR/EU GDPR.
7. Managing your cookie preferences
You can modify your preferences at any time by clicking Consent Preferences (the CookieYes icon) on our website. You can withdraw consent for analytics or marketing cookies whenever you choose.
You can also block or delete cookies via your browser settings:
