Cookies
Updated October 14, 2026 · Version 2026-10-v1
Changes in this version
- First published version. The consent cookie and Google Analytics are live on the marketing pages, not "planned".
- The login cookies (remember me, selected organisation) and the dashboard's theme and unread-notifications cookies are added.
- The lifetime of the notifications cookie is now correct (12 hours).
- "Cookie settings" in the footer exists and is described.
1. What this page covers
This page explains which cookies and similar technologies (local storage) Enskild Firma Milkevich Valiantsin ("Numsolar") uses on numsolar.com, including the solar estimate at numsolar.com/configure and the companies' dashboard, why, and how you can change your choice. How we handle personal data in general is in the privacy policy.
2. The rules
Under the Swedish Electronic Communications Act (lag (2022:482) om elektronisk kommunikation, 9 kap. 28 §) and the GDPR, we may store or read information on your device only with your consent, unless it is strictly necessary to provide a service you asked for. We therefore use necessary cookies without asking, and ask before anything else.

4. Local storage
| Key | Where | Purpose | Lifetime |
|---|---|---|---|
numsolar:wizard-stage-hint-seen |
Solar estimate | Remembers that you have seen the one-time hint about the 3D view, so it is not shown again. Contains only "1" | Until you clear site data |
Editor settings and drafts (accessToken, drawing state) |
Dashboard (3D editor) | Keeps the roof editor working between pages for signed-in users | Until you clear site data |
Local storage never leaves your browser and is not used to identify you.
5. Statistics without cookies
Separately from cookies, our server counts anonymous events in the estimate (address entered, estimate shown, quotes shown, request sent, share), by country and language, keyed by a hash of your estimate link. No cookie is set for this, and the events contain no address, name, e-mail or IP address. See the privacy policy, section 7.
6. How to change your choice
- Cookie settings in the footer of the marketing pages clears your choice and shows the banner again.
- Your browser lets you block or delete cookies and site data for numsolar.com; blocking the necessary session cookie means forms, login and the live estimate pages will not work.
- To opt out of Google Analytics everywhere, Google offers a browser add-on (tools.google.com/dlpage/gaoptout).
7. Supervision and contact
Questions: contact@numsolar.com, Enskild Firma Milkevich Valiantsin. Cookie rules are supervised by the Swedish Post and Telecom Authority (Post- och telestyrelsen, PTS, pts.se) and personal data by the Swedish Authority for Privacy Protection (Integritetsskyddsmyndigheten, IMY, imy.se).
