Information we use

• Google sign-in: your Google account identifier, name, email address, verification status and profile image. We use basic sign-in permissions. We do not request access to your Gmail messages, Drive files or contacts. Authentication credentials and session records are stored on the server to support secure sign-in.
• Catalog content: product data, photographs, branding, customer names and prices, and trading terms that you enter. Editing saves a working copy in your browser. PDF files are generated on your device; export authorization checks your account and subscription without uploading catalog content. Paid Pro users can choose to save a cloud copy, which stores the project and its images in our private Cloudflare storage. Cloud saving is optional.
• Subscriptions: your selected plan, PayPal subscription and transaction references, payer identifier, payment status and billing dates. PayPal processes your payment credentials; we do not receive or store full payment-card details.
• Service and support records: session information, security and error logs, and information you send when requesting support. Infrastructure providers may process IP addresses and request metadata when delivering and protecting the service.

Why we use it

We use this information to sign you in, save and export your catalogs, confirm subscription access, prevent unauthorized use, resolve billing problems and respond to support requests. We do not sell your catalog content or customer price lists. We do not use your uploaded product data to train AI models.

Product usage counts

We count steps such as opening a sample, creating a project, importing a CSV, viewing a preview, opening checkout and completing a PDF export. These first-party counts store only the UTC day, step and total. They do not include product details, customer names, catalog prices, account IDs, cookies or visitor identifiers. Browser Do Not Track and Global Privacy Control signals stop these optional browser counts. Infrastructure security logs are separate. Confirmed payments are counted from verified PayPal transactions using a hashed transaction reference to avoid duplicates; this does not create an advertising profile.

Service providers

Cloudflare hosts the application and stores cloud data. Google provides sign-in. PayPal processes subscriptions and sends payment status notifications. These providers process information under their own policies and may operate in countries outside your country of residence. See Google's privacy policy, PayPal's privacy statement, and Cloudflare's privacy policy.

Browser storage and cookies

Browser storage keeps your working projects and interface preferences. Authentication cookies keep you signed in. Clearing your browser's site data can remove local-only projects. Signing out does not remove those local projects, so take care on shared devices. Saving cloud copies requires a signed-in account with a current paid Pro plan. Existing owned cloud copies remain available to open after a paid period ends. Cloud copies are separate from the working copies on a device.

Access, retention and deletion

You can edit or delete local projects in the workspace and remove saved cloud copies through your account. Keep a backup before deleting important work. Account deletion removes the account record; contact us to request removal of any remaining stored project files or support records. Some billing, security or backup records may need to be retained for accounting, dispute resolution or legal obligations. We do not promise immediate deletion from every backup or third-party payment system.

Depending on your location, you may have rights to access, correct, export, restrict or delete your personal information, or to complain to a privacy authority. Send requests to the contact address above; we may need to verify account ownership. This service is intended for business users and is not directed at children.
