Privacy Policy & Data Protection Guarantee
Last updated: September 2026 - Effective immediately
How Aback PDF protects your documents by ensuring they never leave your device.
At Aback PDF, user privacy is not an afterthought or a marketing slogan. It is the core engineering foundation of our software. We built Aback PDF to guarantee that your confidential documents, financial statements, medical records, and legal contracts never leave your personal computer or mobile device.
We operate no document processing servers. Your files are read and processed entirely inside your local web browser.
Documents exist solely in transient memory during computation. Closing or reloading the browser tab immediately clears all memory buffers.
No sign-up forms, passwords, email captures, or billing details are required to use any of our core document utilities.
Our infrastructure serves only static HTML, CSS, and JavaScript files. It is incapable of receiving or storing document payloads.
1. Introduction & Overview
This Privacy Policy describes how Aback PDF ("we", "us", or "our") handles your information when you visit and use our web applications at abackpdf.com.
Unlike conventional online PDF websites that transmit your confidential files across the internet to remote conversion servers, Aback PDF executes all operations directly within your web browser using modern web execution APIs. This technical distinction fundamentally changes the privacy landscape: we cannot see, read, store, or sell your documents because we never receive them.
2. Information We Do Not Collect
To provide transparency, here is a clear summary of what is never collected or accessed by Aback PDF:
- Document Contents: Text, images, tables, vector paths, form field inputs, and digital signatures contained within your PDF or image files.
- Document Metadata: File names, creation dates, software author tags, GPS coordinates, or embedded revision histories.
- Personal Identity Records: Names, postal addresses, phone numbers, email addresses, credit card numbers, or government identification IDs.
- Account Credentials: We do not offer or require user registration, usernames, or password databases.
3. Web Hosting & Technical Data
When you load web pages on abackpdf.com, your browser requests static application files (HTML, CSS, JavaScript, icons) from our Content Delivery Network (CDN). Like virtually all web services, CDN edge routers automatically process basic connection metadata, including:
- Internet Protocol (IP) address for geographic routing and rate limiting
- Browser type and version (User-Agent string)
- Referring URL and requested page paths
- Date and timestamp of static asset requests
This diagnostic telemetry is used exclusively for DDoS protection, network performance routing, and infrastructure integrity. It is never combined with document contents or user-generated data.
4. Cookies & Local Storage
Local Storage: We use your browser local storage to store your preferred visual theme setting (dark mode or light mode). This information stays on your device and is never uploaded to any remote server.
Cookies: Aback PDF does not set first-party tracking or profiling cookies.
Advertising & Third Parties: To maintain Aback PDF as a free service, we may display non-intrusive advertisements served by third-party ad networks (such as Google AdSense). Third-party vendors may use cookies to serve ads based on a user's prior visits to this website or other websites on the internet. You can manage or opt out of personalized advertising by visiting Google Ads Settings or aboutads.info.
5. Step-by-Step Local Data Flow Architecture
Here is the exact lifecycle of how your files are handled from selection to download:
1. You select or drop a PDF document in the web interface
2. The browser reads the file locally via the FileReader ArrayBuffer API
3. The transformation is executed directly in client-side memory
4. The processed file is assembled into a memory buffer
5. A standard browser Blob URL is generated for instant direct download
Result: Zero outbound network bytes. Complete physical privacy.
You can confirm this anytime: open your browser Developer Tools (press F12), open the Network tab, and run any tool. You will see zero outbound document transfer requests.
6. Regulatory Compliance & Data Sovereignty
GDPR (General Data Protection Regulation): Under the EU GDPR, personal data must be processed lawfully, transparently, and with strict data minimization. By processing documents locally on user devices, Aback PDF eliminates remote processing entirely, satisfying data sovereignty requirements.
CCPA / CPRA (California Consumer Privacy Act): We do not sell, share, or rent personal information or document data to any third party.
HIPAA & Confidentiality: Healthcare and legal professionals frequently handle confidential records. Because Aback PDF does not receive, store, or transmit document content, using Aback PDF does not create an external cloud data transfer risk.
7. Security & User Recommendations
Because all processing happens locally inside your browser sandbox, your document security is tied to the security of your local device. We recommend:
- Keeping your web browser and operating system updated with the latest security patches.
- Avoiding public shared computers when working with highly confidential documents.
- Closing browser tabs after completing sensitive document workflows to immediately flush volatile RAM buffers.
8. Children's Privacy
Aback PDF does not knowingly collect personal information from children under the age of 13. Because our service requires no user registration, personal data from children is never requested or retained.
9. Policy Updates
We may update this Privacy Policy from time to time to reflect new tools, regulatory requirements, or infrastructure enhancements. The latest version will always be published on this page with an updated effective date.

Frequently Asked Questions About Privacy & Security
Do you ever upload, store, or view my documents?
No. Aback PDF operates on a strict zero-upload architecture. When you select a document, it is read into your browser's local memory. All parsing, rendering, organization, and generation occurs directly on your hardware. No document bytes are transmitted across the internet to our servers.
How can I independently verify that my files are not being uploaded?
Open your browser Developer Tools (F12 or right-click and select Inspect), switch to the Network tab, and perform any document action. You will confirm that zero document payload bytes or file streams leave your device.
Do you retain copies of documents for technical support or debugging?
No. Because our static web infrastructure receives zero document payloads, we do not possess and cannot recover, inspect, or retain copies of your documents under any circumstances.
Is Aback PDF compliant with GDPR and international data protection laws?
Yes. Because document processing takes place entirely on your device without entering cloud infrastructure, no personal data crosses international borders. This client-only design inherently supports data minimization and data sovereignty standards under GDPR, CCPA, and HIPAA guidelines.
What cookies or local data does Aback PDF store on my computer?
We use standard browser localStorage solely to remember your preferred visual theme (dark mode or light mode) and your cookie consent state. We do not use persistent identifiers or tracking cookies to index or correlate your document operations.
What happens to document memory when I close the browser tab?
Your documents reside strictly in temporary volatile memory (RAM) allocated to the browser tab. The moment you close the tab or refresh the page, the allocated memory buffers are completely purged and garbage-collected by your browser.
