Cookies Policy

1. About This Policy

This Policy applies to the Service offered at home3dplan.com, including when you use the Service in a standard web browser and when you install it as a Progressive Web App (PWA) for offline use. It covers cookies and similar technologies that are set when you load and interact with the Service.

We have written this Policy in plain English so that you can understand what each category of cookie does and decide which optional categories you wish to allow. If anything here is unclear, you can contact us using the details in the Contact clause below.

2. What Cookies and Similar Technologies Are

A cookie is a small text file that a website places on your device (such as your computer, tablet, or phone) when you visit it. Cookies allow the website to recognise your device, remember information about your visit, and make the Service work as you expect. Cookies set by the site you are visiting are often called first-party cookies, while cookies set by another organisation whose technology is used on the site are called third-party cookies.

We also use similar technologies that serve comparable purposes. The most important of these for our Service is browser local storage, a feature built into modern browsers that lets the Service save data on your device. Because the Service is a Progressive Web App, local storage is central to how it works offline, as explained in the Local Storage and Offline Use clause below.

Cookies can also be grouped by how long they last. A session cookie is temporary and is deleted when you close your browser. A persistent cookie remains on your device for a set period, or until you delete it, so that the Service can remember your preferences across visits. We describe how long our cookies last in the Cookie Duration clause below.

3. Why We Use Cookies and Similar Technologies

We use cookies and similar technologies for a limited and clearly defined set of purposes. These are to keep the Service running and secure, to keep you signed in when you choose to authenticate, to remember your preferences such as your chosen language, to allow your projects and edits to be available offline, and, only if you opt in, to measure how the Service is used so that we can understand and improve it.

No marketing or advertising cookies are active today, and any optional category is switched off until you actively choose to enable it through our cookie banner.

4. Categories of Cookies We Use

We organise the cookies and similar technologies we use into three categories. Only the Necessary category is always active. The Analytics and Marketing categories are optional and are off by default, meaning nothing in those categories is set unless you opt in.

Necessary cookies (strictly necessary, always on, cannot be disabled): These are essential for the Service to function and cannot be switched off through our banner. They support session management, keep you authenticated through Google Firebase when you are signed in, remember your language preference, and provide security. Without these, the editor would not work. Because they are strictly necessary, we do not ask for consent to set them, but we still explain them here for transparency.

Analytics cookies (optional, opt-in, off by default): These support anonymous usage and page-view measurement, used only to understand and improve the Service. They are collected only if you opt in through our cookie banner. If you do not opt in, no analytics cookies are set and no analytics measurement takes place.

Marketing cookies (optional, opt-in, off by default): This category is reserved for possible future advertising partnerships. No marketing or advertising cookies are active today. If we ever activate any in the future, they would remain off by default and would be set only if you opt in, and we would update this Policy accordingly.

5. Local Storage and Offline Use (PWA)

Because the Service is a Progressive Web App, your projects and edits may also be saved in your browser's local storage, which is a technology similar to cookies. This is what allows the Service to work offline, so that you can continue designing even without a network connection.

Data stored in this way stays on your device. It is used to make the Service available and responsive to you, not to track you across other websites. If you clear your browser's storage for the Service, locally stored projects and edits held only on your device may be removed, so please take care before clearing this data.

6. Third-Party Cookies

Some cookies and storage used by the Service are set by trusted third parties whose technology we rely on. Google and Firebase provide our authentication, and may set cookies or use browser storage to keep you signed in when you choose to authenticate. These are part of the Necessary category, because sign-in is essential to using the editor as a signed-in user.

If you opt in to analytics, our analytics provider may set cookies to carry out anonymous usage and page-view measurement. If you do not opt in, this provider does not set those cookies.

The use of cookies and storage by these third parties is governed by their own privacy and cookie policies, which we do not control. We encourage you to review those policies to understand how each provider handles information.

7. How Long Cookies Last (Session vs Persistent)

The cookies and similar technologies we use have different lifespans depending on their purpose. Some are session cookies that exist only while you are using the Service and are removed when you close your browser. Others are persistent and remain for longer so that the Service can remember information such as your language preference, your authentication session, and your cookie choices, so that the banner does not reappear unnecessarily.

Local storage used for offline functionality persists on your device until it is replaced by newer data or until you clear it through your browser. Where a third party such as Google or Firebase sets a cookie, its duration is determined by that provider's own settings and policies.

8. Your Choices and How to Manage Consent

You are in control of the optional cookies the Service uses. When you first visit, we show a cookie banner where you choose which optional categories (Analytics and Marketing) to allow. Necessary cookies are always on and cannot be disabled through the banner, because the editor would not work without them.

You can change your choices at any time using the "Cookies Settings" control, which is available in the banner and in the site footer. Your preference is remembered in your browser so that the banner does not reappear unnecessarily.

You can also block or delete cookies directly through your browser settings. Most browsers let you refuse some or all cookies, delete cookies already stored, and clear local storage. Please note that the necessary cookies are required for the editor to function, so blocking or deleting them will break the Service, as explained in the next clause.

Some browsers offer a "Do Not Track" signal. There is no common industry standard for how websites should respond to this signal. Because our Analytics and Marketing categories are already off by default and are set only if you opt in, the Service does not rely on tracking that a Do Not Track signal would change, and we treat your choices in the cookie banner and your browser settings as the primary way you control optional cookies.

9. What Happens If You Disable Necessary Cookies

The Necessary category supports core functions such as session management, authentication through Google Firebase when you are signed in, your language preference, and security. These functions are essential.

If you block or delete necessary cookies through your browser settings, the Service may not work correctly. In particular, you may be unable to stay signed in, and the editor may not function as intended. We are unable to provide the Service without these necessary cookies.

10. Relationship to the Privacy Policy

This Policy explains how we use cookies and similar technologies. It works alongside our Privacy Policy at /privacy, which describes in more detail how we collect, use, and protect personal data, including any personal data associated with cookies. Where cookies involve the processing of personal data, that processing is also subject to our Privacy Policy.

Your use of the Service is additionally governed by our Terms of Service at /terms. If there is any apparent conflict between this Policy and the Privacy Policy regarding cookies specifically, this Policy applies to the cookie-related matters it addresses, while the Privacy Policy governs the wider handling of your personal data.

11. Changes to This Cookies Policy

We may update this Policy from time to time to reflect changes in the cookies and technologies we use, or for legal, operational, or technical reasons. For example, if we ever activate a Marketing category in the future, we would update this Policy to describe it.

When we make changes, we will revise the "last updated" date shown on this page. We encourage you to review this Policy periodically so that you stay informed about how we use cookies. Where required, we will seek fresh consent for any new optional cookies through the cookie banner.
