Cookie Policy
Last updated: 24 September 2026
This Cookie Policy explains which cookies and local storage Kalma (the “Service”), operated by Tekio Consulting and Engineering Ltd, uses.
1. What are cookies?
Cookies are small text files that a website stores on your device. Local storage (localStorage) is a similar browser mechanism. Both help the site work and remember your preferences.
2. Cookies we use
We only use strictly necessary and functional cookies, listed in the table below. We use no analytics or advertising cookies, so we do not ask for your consent.
| Cookie | Purpose | Duration | Type |
|---|---|---|---|
| __Secure-next-auth.session-token | Keeps you securely signed in. | 30 days | Strictly necessary |
| __Host-next-auth.csrf-token | Protects sign-in against CSRF attacks. | Session | Strictly necessary |
| __Secure-next-auth.callback-url | Remembers which page to return to after signing in. | Session | Strictly necessary |
| kalma_invite | Remembers your early access invitation so you can create an account. | 30 days | Strictly necessary |
| NEXT_LOCALE | Remembers your language preference. | 1 year | Functional |
| sidebar:collapsed | Remembers whether the sidebar is collapsed. | 1 year | Functional |
3. Local storage
We keep some preferences and interface state in your browser’s local storage: light or dark theme, projects view, whether keyboard shortcuts are enabled, the new-project wizard draft and whether you have seen its guided tour. This data is not sent to us or to third parties.
Our product analytics (PostHog) runs without cookies or local storage: it stores nothing on your device.
4. Third-party cookies
When you sign in with Google or connect Autodesk Construction Cloud, those third parties may set their own cookies on their domains, subject to their respective policies.
5. Managing cookies
You can set your browser to block or delete cookies and local storage. If you block strictly necessary cookies, you will not be able to sign in.
6. Changes and contact
We may update this Cookie Policy; we will publish the current version with its date. For any question, write to us at info@kalma.build.
