Cookie Policy
Last updated: 26 June 2026. This policy explains how SriWatt, operated by Matrika OÜ, uses cookies and similar technologies (local and session storage) when you use our website and app. It should be read together with our Privacy Policy.
1. What cookies are
Cookies are small text files a site stores on your device. “Local storage” and “session storage” are related browser technologies that keep small amounts of data in your browser. We group all of these as “cookies” below and split them into two categories:
- Strictly necessary — required to run the service (sign-in, security, saving your preferences and your consent choice). These are exempt from consent under the EU ePrivacy Directive and are always active.
- Analytics (optional) — help us understand aggregate usage so we can improve the product. These load only if you accept them, and you can change your mind at any time below.
2. Your choice
When you first visit, we ask for your consent before loading any analytics. You can update your preference at any time here:

You have not set a preference yet. Essential cookies are always on because the site cannot work without them.

5. Third-party services
Some pages embed services that may set their own cookies when you interact with them — for example the Google Maps location picker and Stripe checkout. Their cookies are governed by those providers’ own policies. See the Google Privacy Policy and Stripe Privacy Policy.
6. Controlling cookies in your browser
Besides the controls above, you can block or delete cookies through your browser settings. Blocking strictly necessary cookies may stop parts of the service (such as staying signed in) from working.
