Cookie Policy
Last updated: 18 August 2026
Constructly sets no advertising cookies and no third-party tracking cookies. The list below is every cookie the platform sets — not a category summary.
| Cookie | What it does | How long | Type |
|---|---|---|---|
constructly_session | Keeps you signed in. Without it there is no way to know which account a request belongs to. | Up to 30 days, or until you sign out | Essential |
constructly_language | Remembers the interface language you chose, so the next visit opens in it. | 1 year | Preference |
constructly_oauth_state, _nonce, _verifier, _return_to | Protects the sign-in exchange against forgery and returns you to the page you started from. Set only while signing in. | Minutes — deleted as soon as sign-in completes | Essential |
dc_session, dc_oauth_* | Older names for the cookies above, read only so that sessions created before the rename keep working. | Same as the cookie they replace | Essential |
Why there is no cookie banner
Under the ePrivacy rules, consent is needed for cookies that are not strictly necessary for a service the user asked for. Every cookie above is either essential to signing in or stores a preference you set yourself. None of them track you across sites, so there is nothing to ask permission for — and a banner that asks anyway only trains people to click through them.
Measurement
We measure page performance — how quickly pages become usable — through Vercel Analytics. It does not use cookies and does not build a profile of you.
Turning them off
Any browser can block or delete cookies. Blocking the session cookie means you cannot stay signed in, so the platform will not be usable.
Maps
Project maps are drawn with OpenFreeMap using OpenStreetMap data. Loading map tiles reveals your IP address to that provider, as any request to any server does. No cookie is set for it.
