Privacy Policy

1. Introduction

Welcome to Developer Box ("we," "our," or "us"). We are committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you visit our website and use our developer tools.

2. Data Collection and Usage

Client-Side Processing

Our core philosophy is "Client-Side First." Most of our tools (like Excel to SQL, JSON Formatter) run entirely in your browser. The data you paste or upload into these tools is processed within your device's memory (RAM) and is not sent to our servers. We do not see, store, or have access to this data.

Usage Data

We may collect anonymous usage statistics (e.g., which tools are most popular) using privacy-focused analytics to help us improve the user experience. This data does not contain any personally identifiable information (PII) or the content of your files.

3. Cookies

We use essential cookies to enhance your experience, such as remembering your theme preference (Light/Dark mode). Our analytics and advertising partners may also set their own cookies — see section 4 below. For full details, please refer to our Cookie Policy.

4. Advertising and Google's Use of Cookies

Developer Box is free to use and is supported by advertising. We work with third-party advertising partners, including Google, to display ads on this site.

• Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
• Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our site and/or other sites on the Internet.
• These advertising cookies are set by the advertising provider, not by us. We do not have access to the data they collect, and the content you process in our tools is never shared with them.

Opting Out of Personalized Advertising

You can opt out of personalized advertising at any time. Opting out does not remove ads — it means the ads you see will no longer be tailored to your interests.

• Turn off ad personalization in Google's Ad Settings: https://myadcenter.google.com/personalizationoff
• Learn how Google uses data when you use our partners' sites or apps: https://policies.google.com/technologies/partner-sites
• You can also opt out of third-party vendor cookies through the Digital Advertising Alliance or Your Online Choices (EU), and block or delete cookies in your browser settings at any time.

5. Third-Party Services

We may use third-party services for hosting, content delivery, and analytics. These providers have their own privacy policies and may collect data such as IP addresses and user agent strings as part of their standard logging practices for security and performance monitoring.

6. Legal Basis for Processing (EEA/UK Visitors)

Where the GDPR applies, we rely on the following legal bases: consent for analytics and advertising cookies, and legitimate interest for operating and securing the website. Where consent is required, we ask for it before non-essential cookies are set, and you may withdraw it at any time through your browser settings or the opt-out links above.

7. Your Privacy Rights

Because we do not collect or store your files or account data, we usually hold no personal information about you to retrieve or delete. Depending on where you live, you may still have the following rights regarding any data our providers process:

• EEA/UK (GDPR): the right to access, rectify, erase, restrict, or object to processing, the right to data portability, and the right to lodge a complaint with your local supervisory authority.
• California (CCPA/CPRA): the right to know what personal information is collected, the right to delete it, the right to correct it, and the right to opt out of the "sale" or "sharing" of personal information for cross-context behavioural advertising. We do not sell personal information for money. Using the ad opt-out links above serves as your opt-out signal for personalized advertising.

To exercise any of these rights, contact us using the details in the "Contact Us" section below. We do not discriminate against users who exercise their privacy rights.

8. Data Retention

Data you enter into our tools exists only in your browser's memory and is discarded when you close or reload the page. Preference cookies (such as your theme choice) remain on your device until you clear them. Retention of advertising and analytics cookies is governed by the respective provider's policy.

9. International Data Transfers

Our hosting, analytics, and advertising providers may process data on servers located outside your country, including in the United States. Where required, these transfers rely on safeguards such as the European Commission's Standard Contractual Clauses.

10. Children's Privacy

Developer Box is intended for software developers and is not directed at children under 13 (or under 16 in the EEA/UK). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it.

11. Security

The site is served exclusively over HTTPS. Because tool data never leaves your device, the most common risk of a server-side data breach does not apply to the content you process here. No method of transmission over the Internet is completely secure, however, and we cannot guarantee absolute security.

12. Changes to This Policy

We may update our Privacy Policy from time to time. We will post the revised policy on this page and update the "Last updated" date above. Material changes will be highlighted on this page.
