Privacy Policy

Last Updated: May 19, 2025

1. Introduction

Welcome to Kestrel Tools ("we," "us," "our"). We are committed to protecting your privacy and ensuring you have a positive experience on our website, kestreltools.com (the "Site"), and when using our online utilities (collectively, the "Services"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our Services. Please read this policy carefully. If you do not agree with the terms of this privacy policy, please do not access the site.

2. Our Privacy Commitment

One of our core values is treating your privacy as a top priority. Unlike many similar tools websites:

•

We design our tools to process most data client-side (directly in your browser) whenever technically possible.

•

We minimize server-side storage of any inputs or data you provide to our tools.

•

We do not use intrusive third-party tracking for advertising purposes, and we do not sell your personal data.

•

We strive to maintain a clean, ad-free user experience.

3. Information We Collect

We may collect information about you in a variety of ways. The information we may collect via the Services depends on the content and materials you use, and includes:

a. Information You Provide to Our Tools

When you use our tools, you may input content such as code, JSON data, text for conversion or formatting, or files ("User Input Data"). For most tools, this User Input Data is processed entirely within your browser. For tools that require server-side processing, we handle User Input Data as described in Section 5 ("Data Processing and Storage"). We do not permanently store your User Input Data unless a feature explicitly requires it for your benefit (e.g., a user-initiated save for later use, with your consent) and this will be clearly communicated.

b. Account Information

If you choose to create an account (where available), we collect your email address and authentication information (e.g., password, or through a third-party provider like Google). We may also store your user preferences, tool configurations, and other account-related settings to personalize and improve your experience.

c. Automatically Collected Information (Usage Data)

When you access and use our Services, we automatically collect certain information about your device and your interaction with our Services ("Usage Data"). This may include your IP address (which may be anonymized where possible), browser type and version, operating system, referring URLs, pages viewed, links clicked, time spent on pages, and dates and times of access. This information is primarily collected through server logs and analytics services like Firebase Analytics. This Usage Data helps us understand how our Services are being used, maintain security, and improve functionality.

4. How We Use Your Information

Having accurate information permits us to provide you with a smooth, efficient, and customized experience. Specifically, we may use information collected about you via the Services to:

•

Provide, operate, and maintain our Services and tools.

•

Improve, personalize, and expand our Services based on user interactions and feedback.

•

Understand and analyze how you use our Services for development and optimization.

•

Maintain the security, stability, and integrity of our Services.

•

Create and manage your account (if applicable).

•

Communicate with you, either directly or through one of our partners, including for customer service, to provide you with updates and other information relating to the Services, and for marketing and promotional purposes (with your consent, where required).

5. Data Processing and Storage for Tools

As emphasized, most of our tools process data directly in your browser (client-side). For any tools that necessitate server-side processing for their functionality, we adhere to the following principles regarding your User Input Data:

•

Temporary Processing: User Input Data sent to our servers is typically retained only for the duration necessary to perform the requested operation and deliver the result back to you. We do not permanently log or store this specific input data unless essential for a feature you explicitly use and are informed about.

•

Secure Transmission: We use HTTPS (SSL/TLS) to encrypt all data in transit between your browser and our servers.

•

No Profiling or Mining of Inputs: We do not analyze, profile, or extract information from your User Input Data for purposes other than providing the tool's functionality.

6. Cookies, Local Storage, and Similar Technologies

We use cookies, browser localStorage, and similar tracking technologies to operate and enhance your experience on our Services, analyze usage, and provide core functionality. These include:

•

Essential Cookies & Local Storage: These are strictly necessary for the Services to function correctly and ensure security. Examples include session cookies for logged-in users (if applicable) or security tokens. These are typically session-based or have a short lifespan and are used without requiring prior consent, though their use is disclosed here.

•

Preference Cookies & Local Storage: These remember your settings and preferences to personalize your experience (e.g., UI theme choices, last used tool configurations, or keeping your input in a tool during your session). These may persist longer to remember your choices between visits. We will seek your consent for these where required by law.

•

Analytics Cookies & Local Storage: These help us understand how you use our Services (e.g., via Firebase Analytics, to track page views, tool interactions, and general usage patterns). This data is often aggregated and helps us improve our Services. We will seek your consent for these where required by law.

Data stored in localStorage by our tools for functional purposes (e.g., retaining input data within a tool during your session, caching tool settings) is processed directly in your browser and is not typically transmitted to our servers unless essential for the tool's operation as described in Section 5. You can control cookies through your browser settings and clear localStorage data via your browser's history/cache clearing options, although this may limit some functionality. For more information on how Firebase uses data, please review their policies. We will provide a mechanism for you to manage your consent preferences for non-essential cookies and localStorage where applicable.

7. Third-Party Services

We use a limited number of third-party services to help operate and improve our Services. These include:

•

Firebase (Google): For backend infrastructure, database (Firestore, for user accounts and settings if applicable), hosting, authentication (e.g., Sign in with Google), and analytics (Firebase Analytics). Firebase may collect Usage Data as described in their privacy policy.

These services may collect information as described in their respective privacy policies. We select and configure these services with a focus on privacy and data minimization where possible.

8. Data Security

We implement appropriate administrative, technical, and physical security measures designed to protect your information from unauthorized access, use, alteration, and disclosure. This includes using HTTPS encryption for data transmission and restricting access to personal data. However, please be aware that no method of transmission over the Internet or method of electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your personal information, we cannot guarantee its absolute security.

9. Your Data Protection Rights (e.g., under GDPR/CCPA)

Depending on your location and applicable law, you may have certain rights regarding your personal information. These may include the right to:

•

Request access to the personal data we hold about you.

•

Request correction of inaccurate or incomplete data.

•

Request deletion/erasure of your personal data, subject to certain conditions.

•

Object to or restrict certain types of processing of your personal data.

•

Request data portability (to receive your data in a structured, commonly used, and machine-readable format).

•

Withdraw consent at any time (where processing is based on consent), without affecting the lawfulness of processing based on consent before its withdrawal.

•

Lodge a complaint with a supervisory authority.

To exercise these rights, or if you have questions about them, please contact us using the information in the "Contact Us" section. We will respond to your request consistent with applicable law. If you have an account, you may also be able to review and update certain personal information directly within your account settings.

10. Children's Privacy

Our Services are not directed to children under the age of 16 (or the applicable age of digital consent in your jurisdiction). We do not knowingly collect personal information from children under this age. If we become aware that we have collected personal information from a child without verification of parental consent, we will take steps to remove that information from our servers. If you believe we might have any information from or about a child under this age, please contact us.

11. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes to our practices or for other operational, legal, or regulatory reasons. If we make material changes, we will notify you by updating the "Last Updated" date of this Privacy Policy and posting the new Privacy Policy on this page. We may also provide notice through the Services or, if you have an account with us, by email, prior to the change becoming effective. We encourage you to review this Privacy Policy periodically for any changes.
