Privacy Policy

1. Core Commitment: 100% Client-Side Processing

At BrowserTools (https://browsertools.online), user privacy is our foundational architecture, not an afterthought. Unlike typical online tool websites, the utilities provided on this platform execute entirely inside your web browser using client-side JavaScript, WebAssembly, and modern HTML5 APIs.

Your uploaded files, converted documents, typed text, generated passwords, and media never leave your device. We operate zero file-upload backends, maintain no remote user databases, and require no account registration.

2. Local Storage & Cookies

The site uses browser localStorage solely to persist client-side user preferences, such as your selected dark/light theme. This data remains on your physical machine and is never transmitted to any server. Clearing your browser cache or site data removes it immediately.

3. Google AdSense & Third-Party Advertising

To keep all 186+ tools completely free without paywalls or usage quotas, BrowserTools displays advertisements served by third-party advertising partners, including Google AdSense.

• Third-party vendors, including Google, use cookies (including the DoubleClick DART cookie) to serve ads based on a user's prior visits to this website or other websites across the Internet.
• Google's use of advertising cookies enables it and its partners to serve personalized or contextual ads to users based on their visit to BrowserTools and other sites on the Internet.
• Users may opt out of personalized advertising at any time by visiting Google Ads Settings. Alternatively, you can opt out of a third-party vendor's use of cookies for personalized advertising by visiting aboutads.info choices or youronlinechoices.com.
• For full transparency regarding how Google collects, protects, and uses data when you interact with partner websites, please visit Google's partner policy page: How Google uses information from sites or apps that use our services.

4. Network-Enabled Utilities

While 98% of tools operate completely offline once loaded, a small handful of utilities require external network calls to function properly:

• IP Lookup & What Is My IP: Queries public geolocation endpoints directly from your browser.
• Internet Speed Test: Measures bandwidth throughput directly against public edge endpoints.
• Password Breach Checker: Utilizes k-anonymity protocol, sending only the first 5 characters of a SHA-1 hash to the HaveIBeenPwned API. Your plaintext password never leaves your browser.

5. GDPR & European Privacy Rights

If you reside within the European Economic Area (EEA) or the United Kingdom, you are entitled to full rights under the General Data Protection Regulation (GDPR). Because BrowserTools does not collect, store, or profile your personal data or uploaded files, we hold no user data to inspect, rectify, or delete. Where advertising cookies are used, a consent banner powered by Google's certified Consent Management Platform lets you accept, reject, or customise personalised advertising before ads load, and you can change your choice at any time via the Ad consent section of this page or by clearing your browser storage for this site. For further inquiries regarding cookie consent and advertising preferences, contact us.

6. California Consumer Privacy (CCPA / CPRA)

Under the California Consumer Privacy Act, California consumers have the right to know what personal data is collected and to request its deletion. BrowserTools does not sell personal information or share personal data with data brokers.
