Privacy Policy

1. Introduction & Core Principles

Rasterbator.app is committed to protecting your privacy. We believe that powerful web tools should respect user data autonomy. Unlike traditional image utilities that require uploading personal photographs to cloud servers for remote rendering, Rasterbator.app is engineered from the ground up as a client-side static web application.

This Privacy Policy explains how our zero-upload architecture operates, what minimal diagnostic information is collected when you visit our website, how cookies and third-party advertising services function, and how you can exercise your statutory data privacy rights.

2. 100% Client-Side Image Processing Architecture

When you create a multi-page poster using Rasterbator.app:

• Local Decoding in Browser RAM: Your selected digital images (JPEG, PNG, WebP) are read directly from your device file system into browser memory using standard HTML5 Canvas APIs and Web Workers.
• No Image Uploads to Application Servers: Your original photos, rasterized dot matrices, and assembled PDF documents never leave your computer or phone during the poster generation workflow. We do not operate an image processing backend that stores or analyzes your visual files.
• Remote URL Loading: If you input a public web URL to import an image, the image pixels are fetched into your browser window for local canvas manipulation. No copies are permanently stored on our infrastructure.

3. Browser Storage & Offline Project Caching

To provide a smooth user experience, Rasterbator.app utilizes browser-native storage technologies (such as localStorage and IndexedDB) on your local device:

• Autosave & Project Drafts: If enabled, low-resolution preview thumbnails and grid parameters are saved locally so you can resume work without losing progress.
• UI Preferences: Settings such as selected paper format (A4 vs. US Letter) and color palette choices are remembered on your device for subsequent sessions.
• Local Control: All locally stored project data can be permanently erased at any time by clearing your browser cache or site data for rasterbator.app.

4. Network Telemetry, Security & Hosting Logs

When your browser requests web pages from Rasterbator.app, our content delivery network (Cloudflare) automatically receives standard HTTP request headers. This technical data may include your IP address, browser user-agent, operating system version, referring URL, timestamp, and requested asset paths.

This information is processed exclusively for essential security purposes, such as mitigating Distributed Denial of Service (DDoS) attacks, detecting automated bot abuse, diagnosing network latency, and maintaining reliable worldwide availability. Log data is retained in anonymized form and is never linked to personal identity.

5. Third-Party Advertising & Google Cookies

To keep our poster maker 100% free for students, educators, and hobbyists worldwide, we may display third-party advertisements via partners such as Google AdSense:

• Google and its advertising partners use cookies and device identifiers to serve ads based on prior visits to our site and other internet properties.
• Cookies help partners limit repetitive ad impressions, detect click fraud, and evaluate ad campaign efficacy.
• Users may opt out of personalized advertising by visiting Google Ads Settings or through the Digital Advertising Alliance opt-out portal.
• For complete details on how cookies are deployed and managed, please review our dedicated Cookie Policy.

6. GDPR & CCPA / CPRA Statutory Privacy Rights

Depending on your geographic location, you may possess specific rights under data protection laws such as the European Union General Data Protection Regulation (GDPR) or the California Consumer Privacy Act (CCPA):

• Right of Access & Portability: You may request confirmation regarding whether any personal data concerning you is processed. Because we do not require user accounts or store user images, our processing is restricted to transient network logs and client-side device storage.
• Right to Erasure (“Right to be Forgotten”): You may request deletion of any contact correspondence or stored data held by our support team.
• Right to Object & Restrict Processing: You may object to non-essential cookie tracking through your browser settings or privacy opt-out tools.
• Non-Discrimination: We do not discriminate against users who choose to exercise their statutory privacy rights.

7. Children's Privacy Notice

Rasterbator.app is a general audience creative tool designed for poster printing and wall art. We do not knowingly collect personal identifiable information from children under the age of 13 (or under 16 in applicable European jurisdictions). If a parent or guardian discovers that a child has provided personal information via email correspondence, please notify us immediately so we can promptly delete the records.

8. Changes to This Policy & Contact Desk

We may periodically update this Privacy Policy to reflect technical enhancements, architectural updates, or regulatory revisions. The “Updated” date at the top of this document indicates the latest revision.
