The short version. Your projects never leave your device: walls, openings, settings and the design images you load are stored locally in your browser, not on our servers. We process only what we need to run your account and billing: your email, your subscription status and your billing details. We do not sell data and we do not run advertising.

1. What stays on your device

Wallsizer stores your projects (dimensions, openings, settings) and uploaded design images locally in your browser, using localStorage and IndexedDB. This data is not transmitted to or stored on our servers. It remains on your device until you delete it or clear your browser data. Documents you export (PDF, JPG) are generated in your browser and saved by you.

2. What we collect, why, and on what legal basis

3. Who processes data on our behalf

Each processor acts under a data processing agreement and its own security measures.

4. International transfers

Some processors are based in the United States. Transfers rely on the EU-US Data Privacy Framework, under which Stripe and Cloudflare are certified, and, where the framework does not apply, on the European Commission's Standard Contractual Clauses together with additional safeguards.

5. How long we keep data

6. Your rights

Under the GDPR you have the right of access, rectification, erasure, restriction, portability, and the right to object to processing based on legitimate interest. Write to hello@wallsizer.com and we will respond within one month. You also have the right to lodge a complaint with a supervisory authority: in Romania, the National Supervisory Authority for Personal Data Processing (ANSPDCP, dataprotection.ro), or the authority in your own EU country.

7. Cookies and local storage

The Wallsizer site does not set advertising or cross-site tracking cookies, and our analytics are cookieless. The application uses localStorage and IndexedDB strictly to store your projects and preferences on your device, which is essential functionality, not tracking. The Stripe checkout and customer portal, hosted by Stripe, set the cookies strictly necessary for payment security and fraud prevention under Stripe's own privacy policy.

8. Children

Wallsizer is a professional tool and is not directed at children. We do not knowingly process data of persons under 16.

9. Changes

If we change this policy in a material way, we will notify subscribers by email before the change takes effect.
