1. What cookies are
Cookies and similar browser technologies are small text files that websites store on your device. We use them to make the service work, remember your choices and improve the service. This statement is part of Kaiku's Privacy Policy and is based on the ePrivacy Directive (2002/58/EC) and GDPR.
2. Strictly necessary cookies (no consent required)
These cookies are required for the service to function, such as keeping you signed in and security. They cannot be disabled in the service.

| NEXT_LOCALE | Remembering your language | 1 year | next-intl |
| __Host-csrf | Protection against forged requests (CSRF) | Session | Kaiku |
3. Analytics cookies (consent required)
With your consent we use product analytics to improve the service. You can decline — this does not affect your use of the service.

These cookies improve your experience by remembering your choices.

5. Third-party cookies and tracking
We do not use third-party cookies for advertising or marketing profiles. The Stripe checkout (when you go through a purchase flow) may set Stripe's own cookies — they are governed by Stripe's privacy policy.
6. Managing your consent
You can change your consent at any time with the cookie preferences control at the top of this page. You can also block cookies in your browser settings — note that blocking strictly necessary cookies may break sign-in. Consent is stored for 12 months, after which we ask again.
7. Mobile app specifics
The Kaiku mobile app (iOS, Android) does not use browser cookies. Equivalent local state is stored securely on the device (iOS Keychain, Android EncryptedSharedPreferences). You have the same controls in the app's Settings view.
