Your projects are saved locally in your browser and synced to your Wallsizer account, so your work follows you across devices. A reduced copy of each design image is stored with the project so your devices, and on the Team plan your team, see the same design; the original print file never leaves your device. 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.
Wallsizer stores your projects (dimensions, openings, settings) locally in your browser and syncs them to your account on our servers, so you can continue on another device and, on the Team plan, share them with your team. On the Team plan, teammates also see who last worked in a shared project and roughly when (the display name set by the account owner, or the email prefix) — that is how the app warns people away from a project a colleague is editing. Deleting a project in the app removes it from your account, from your other devices at their next sync, and deletes any design copies stored for it on our servers.
Uploaded design images: a reduced copy of the image is stored with the project in a private bucket on our servers, only so that your other devices and, on the Team plan, your team members see the same design; the original file never leaves your device. Documents you export (PDF, JPG) are generated in your browser and saved by you.
Measure links (Team plan): when you send a measuring link, the room dimensions your client enters (walls, doors, windows) are transmitted over an encrypted connection and stored as part of the project in your account, and nowhere else. The link expires on its own after 7 days and you can revoke it at any time. We do not use this data for anything except showing it to you in your project.
Support attachments: screenshots you attach to a support message are delivered to our support inbox by email and are not stored on our servers.
Each processor acts under a data processing agreement and its own security measures.
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.
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.
The Wallsizer site does not set advertising or cross-site tracking cookies, and our analytics are cookieless. The application uses localStorage and IndexedDB to store your projects and preferences on your device and syncs project data to your account, 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. Clicks on the pricing links of this site are counted in aggregate only — which plan, which campaign the visitor came from, and the day — with no IP address, no cookie and no identifier of any kind.
Your projects can contain personal data of your own clients: a project name, the label on a measure link, the measurements a client submits. For that data you are the controller and Wallsizer processes it only on your behalf, to store and sync your projects under the contract between us. We use it for nothing else. If you need a signed data processing agreement for your records, write to hello@wallsizer.com.
Wallsizer is a professional tool and is not directed at children. We do not knowingly process data of persons under 16.
If we change this policy in a material way, we will notify subscribers by email before the change takes effect.
