Cookie and Browser Storage Policy

This Policy explains cookies, local storage, session storage and similar browser technologies used by the Metropolygonia website and application.

1. Who operates the website

The operator is KUNZ STANISLAW, trading as Metropolygonia, P.IVA 02894360995, registered at Via Camillo Benso Conte di Cavour 42/1, Bogliasco (GE), Italy.

2. Categories

Metropolygonia uses three categories of browser technology:

• Necessary: required for requested functions such as sign-in, security, language choice, local project state and recording the consent decision. These technologies cannot be disabled through the consent banner because the requested service cannot operate reliably without them.
• Statistics: Microsoft Clarity analytics, heatmaps and session playback. These technologies are optional and activate only after Statistics consent.
• Marketing: Reddit Pixel advertising measurement and attribution. This technology is optional and activates only after Marketing consent.

3. Necessary technologies

Necessary technologies include:

• Supabase Auth browser storage: keeps the authentication session, refreshes session tokens and protects access to account data.
• Cookiebot consent storage: records whether non-essential technologies were accepted, rejected or configured by category.
• metropolygonia-language in localStorage: stores the selected interface language.
• archiform-realistic-textures-v1 in localStorage: stores local texture choices and scale settings used by the application.
• archiform-city-project-v1 in localStorage: stores a local city-project draft.
• metropolygonia-oauth-acceptance in sessionStorage: temporarily preserves legal-acceptance state during an OAuth redirect.

Additional strictly necessary security or session entries may be created by the authentication or hosting services. The current Cookiebot declaration below lists detected cookies and their durations.

Clearing necessary browser storage may sign you out, reset preferences or remove unsaved local project data.

4. Microsoft Clarity statistics

After you grant Statistics consent, Metropolygonia uses Microsoft Clarity to understand how public pages and the application are used and to identify usability and technical problems. Clarity may create aggregate statistics, heatmaps and session-playback data and may use cookies or equivalent identifiers after consent.

Metropolygonia configures Clarity through consent controls so that optional analytics does not activate before a valid Statistics choice. Authentication credentials, full email addresses, private project names, model files and texture files must not be intentionally sent to Clarity.

Under Microsoft's current retention documentation, ordinary playback data is retained for 30 days, while labelled or favourited sessions, heatmaps and certain aggregated interaction data may be retained for up to 9 months.

Microsoft processes Clarity data under Microsoft's terms and privacy statement.

5. Reddit Pixel marketing measurement

After you grant Marketing consent, Metropolygonia loads Reddit Pixel a2_jga08wizjp19 and sends one PageVisit event for the page. The purpose is to measure whether visits and later actions followed a view of or click on a Metropolygonia advertisement on Reddit, attribute conversions, evaluate campaigns and optimise Reddit advertising.

The base pixel integration may make the current page URL and referrer, event time, IP and network information, browser, device and screen information, Reddit click or campaign identifiers when present, and a pixel/browser identifier available to Reddit. Metropolygonia does not intentionally send account email addresses, authentication credentials, private project names, project geometry, model files, texture files or form contents through this base PageVisit event.

The Reddit loader is not requested and no PageVisit is sent before Marketing consent. If Marketing consent is withdrawn, Metropolygonia stops issuing Reddit events and calls Reddit's first-party-cookie disabling command; on later page loads the pixel remains blocked unless Marketing consent is granted again. The current Cookiebot declaration below lists the Reddit storage items detected on the production domain, their providers, purposes and durations.

Reddit processes pixel data under the applicable Reddit Business Tool Terms and Reddit privacy information. More information about recipients and international transfers is provided in the Privacy Policy.

6. Consent choices

On the first relevant visit, the consent banner offers:

• Accept all;
• Reject non-essential; and
• Customise.

Rejecting or closing the banner without accepting keeps both Statistics and Marketing technologies disabled. Withdrawing either category stops future collection for that category. Refusing Statistics or Marketing does not restrict the generator, account, project editing or exports.

You can change or withdraw your choice at any time through the Cookie settings control in the website footer. Withdrawal does not affect processing that was lawful before withdrawal.

Consent is requested again when required by the configured renewal period, when the technology categories materially change or when the recorded choice is no longer available.

7. Email and in-app marketing

Email marketing and in-app promotional choices are account records, not browser trackers. They are requested separately from both Statistics consent and the Marketing browser category used for Reddit Pixel.

Resend is used server-side to deliver transactional and double-opt-in email. Resend does not load a marketing tracker in the Metropolygonia browser application for this purpose.

8. Browser controls

Your browser can delete or block cookies and storage. Blocking necessary technologies may prevent sign-in, cloud functions or preservation of local preferences and drafts.

Browser privacy controls operate independently from the Metropolygonia consent banner. Where a browser signal conflicts with a stored optional choice, Metropolygonia seeks to apply the more privacy-protective state where technically supported.

9. Current cookie declaration

The declaration below is generated from the Cookiebot domain scan and lists the cookies and similar technologies currently detected on the domain, including provider, purpose and duration.

10. Changes and contact

Material changes receive a new version and effective date. Questions about browser technologies may be sent to kunzdesign2017@gmail.com.
