Zero-Upload Client-Side Guarantee

Privacy Policy

Effective Date: October 2026 • Last Reviewed: October 2026

Summary of Our Core Privacy Principles

BWTools.uk operates on a fundamental Zero-Upload Client-Side Architecture. When you use any utility (such as AI background removal, PDF merging, image compression, OCR, or password generation), your files, data, and computations remain 100% inside your local browser memory (RAM). We do not transmit, copy, log, or store your documents or images on any server.

1. 100% Client-Side In-Browser Processing

Unlike traditional cloud conversion websites that require uploading your private files to remote cloud servers, BWTools.uk executes all tool algorithms locally on your device using WebAssembly (WASM), Web Workers, HTML5 Canvas, and the Web Crypto API.

  • No File Uploads: Your documents, photos, audio clips, and text never leave your computer or mobile device.
  • Volatile Memory Only: All operations occur strictly in volatile client memory (RAM) and are cleared immediately upon refreshing or closing the browser tab.
  • No Server-Side Databases: We maintain zero databases of user files, conversion histories, or personal records.

2. Cookies and Third-Party Advertising (Google AdSense)

We use third-party advertising companies, including Google AdSense, to serve advertisements when you visit our website. These companies may use cookies, web beacons, device identifiers, and similar technologies to collect information (not including your name, address, email address, or telephone number) about your visits to this and other websites in order to provide advertisements about goods and services of interest to you.

Mandatory Google Advertising Disclosures:

  • Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to BWTools.uk or other websites on the Internet.
  • Google's use of advertising cookies enables it and its partners to serve ads to our users based on their visits to our site and/or other sites across the Internet.
  • Users may opt out of personalized advertising by visiting Google Ads Settings.

Alternatively, you can opt out of a third-party vendor's use of cookies for personalized advertising by visiting:

3. UK GDPR, EU GDPR & Consent Management (EEA/UK Visitors)

If you are located in the United Kingdom or the European Economic Area (EEA), you are protected by the UK Data Protection Act 2018 (UK GDPR) and EU Regulation 2016/679 (EU GDPR).

Under Google's EU User Consent Policy and applicable ePrivacy regulations (PECR), we deploy a consent mechanism compliant with the IAB Europe Transparency and Consent Framework (TCF v2.2). Visitors from the UK and EEA are presented with choices regarding the storage of cookies and the use of personal data for personalized advertising, non-personalized advertising, and measurement.

Your Statutory Rights Under GDPR:

  • Right of Access: You have the right to request copies of any personal data we hold about you.
  • Right to Rectification: You have the right to ask us to rectify information you believe is inaccurate.
  • Right to Erasure ("Right to be Forgotten"): You have the right to ask us to erase your personal information.
  • Right to Restrict or Object to Processing: You may object to or restrict certain types of data processing.
  • Right to Lodge a Complaint: You have the right to file a complaint with the UK supervisory authority, the Information Commissioner's Office (ICO).

4. California Privacy Rights (CCPA / CPRA)

Under the California Consumer Privacy Act (CCPA) and California Privacy Rights Act (CPRA), California residents have specific privacy rights:

  • No Sale or Sharing of Personal Data: BWTools.uk does not sell, rent, or trade your personal information or file content to any third parties for monetary or valuable consideration.
  • Right to Know & Delete: You have the right to request disclosure of categories of personal data collected and request deletion.
  • Non-Discrimination: You will never be discriminated against for exercising your CCPA rights. All tools remain 100% free and functional regardless of privacy preferences.

5. Local Storage & Browser Preferences

BWTools.uk uses the browser's native localStorage API strictly to store your interface settings locally on your own computer:

  • theme: Remembers whether you prefer Dark Mode or Light Mode.
  • bw_cookie_consent: Stores your cookie preference so you are not prompted repeatedly on every page load.

This data is strictly confined to your personal device and is never uploaded, synchronized, or analyzed on remote servers.

6. Web Server Logs & Security Telemetry

When you access BWTools.uk, standard web hosting servers and content delivery networks (CDNs, such as Cloudflare or GitHub Pages) automatically log minimal connection metadata:

  • Internet Protocol (IP) address (anonymized or hashed where feasible).
  • Browser user agent string and operating system version.
  • Referrer URLs, HTTP status codes, and access timestamps.

These transient access logs are utilized strictly for cybersecurity defenses (mitigating Distributed Denial of Service attacks), technical diagnostics, and ensuring site availability. They are never linked to personal identities.

7. Third-Party Links & Services

Our website may contain links to external websites, including community support platforms (such as Ko-fi) and developer resources (GitHub). We have no control over and assume no responsibility for the privacy policies, terms, or practices of external third-party services. We encourage you to review their individual privacy policies.

8. Protection of Children's Privacy (COPPA)

BWTools.uk is not directed to individuals under the age of 13 (or under 16 in the UK/EU). Because our utilities run client-side without registration or collection of personal details, we do not knowingly solicit or collect personally identifiable information from children.

9. Data Controller & Contact Inquiries

The Data Controller responsible for BWTools.uk under the UK Data Protection Act 2018 and UK GDPR is Jon Butterworth (BW Tools, United Kingdom).
