Privacy Policy
Last Updated: July 29, 2026 · Official Data Protection & Privacy Specification
At ToolMono, we believe user privacy should be built into core software practices. This Privacy Policy details our browser-based processing model, data handling practices, local storage usage, and third-party advertising transparency disclosures.
Where supported, text, code, and files process locally in browser memory.
We do not store, inspect, or retain your tool inputs or output payloads.
Access developer tools directly without registration or sign-up.
1. Client-Side Processing & Local Execution Architecture
Traditional web applications route user data (such as JSON payloads, SQL queries, PDF documents, or CSV spreadsheets) to backend server clusters for processing. This architectural pattern can create privacy hazards when developers paste confidential API keys, database credentials, or proprietary source code.
Where supported, ToolMonooperates on a client-side execution model. When you open a browser-processed tool—such as JSON Formatter, PDF Editor, JWT Decoder, Image Compressor, or Text Diff Checker—the HTML, CSS, JavaScript, and WebAssembly binaries are loaded in your browser. All subsequent parsing, transformation, validation, and rendering execute entirely inside your device's local CPU and V8 JavaScript memory thread.
For client-side tools, your data is processed locally in your browser and is not transmitted to ToolMono servers. Disconnecting your internet connection after initial page load will not interrupt the functionality of fully browser-based utilities.
2. Information We Collect and Information We Do NOT Collect
Information We Do NOT Collect
- Tool Inputs & Payloads: We do not log, capture, record, or store any text, code, JSON, passwords, JWT tokens, PDF files, or image files entered into our browser-processed tools.
- Personal Identity Data: We do not collect names, email addresses, phone numbers, or physical addresses for tool usage.
- User Credentials: We do not require accounts, passwords, or authentication profiles.
Information Collected Automatically
Like virtually all web applications, our web hosting infrastructure automatically logs standard technical HTTP request headers for server operational health, security mitigation, and performance monitoring. These server logs may include:
- IP address (anonymized where applicable for privacy compliance)
- Browser user-agent string and operating system type
- Requested URL path and timestamp
- HTTP referrer headers
These server logs are used exclusively for preventing Distributed Denial of Service (DDoS) attacks and maintaining platform availability. They are never linked to individual tool payload interactions.
3. Local Storage, Cookies & Advertising Disclosures
A. Local Browser Storage
We use your browser's localStorage API strictly to preserve local UI preferences—such as dark mode preference and your favorited tools list. This preference data remains on your physical device and is not transmitted to remote servers.
B. Google AdSense & Advertising Disclosures
At the time of publication, advertising may not be enabled on all ToolMono pages. ToolMono may display advertising through Google AdSense or other advertising partners when advertising is enabled. If advertising services are enabled, this Privacy Policy applies to the relevant advertising technologies and third-party providers.
When advertising is enabled, third-party advertising providers, including Google, may use cookies, web beacons, or similar technologies to provide, personalize, measure, and improve advertisements, prevent fraud, and analyze site traffic, subject to applicable policies and user choices.
- Third-party vendors, including Google, may use cookies to serve ads based on a user's prior visits to ToolMono or other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to our site and/or other sites on the Internet.
- Users may opt out of personalized advertising by visiting Google's Ad Settings page at adssettings.google.com or via aboutads.info.
- To learn how Google collects and processes data when you use partner sites, visit policies.google.com/technologies/partner-sites.
4. Data Protection & Regulatory Compliance
Because ToolMono relies primarily on client-side execution for its developer tools and does not store personal tool input data on remote servers, our architectural design supports compliance with global privacy regulations:
- GDPR (European Union): Users retain sovereignty over tool inputs because data processed locally stays on their local device. Where advertising is enabled, user preferences regarding third-party cookies are respected.
- CCPA (California): We do not sell user tool input data or personal information as defined by the California Consumer Privacy Act.
- Data Privacy & Security: Browser-based tool inputs and files are processed locally in your browser without being uploaded to remote servers.
5. Security Policies & Data Retention
All traffic between your browser and ToolMono is encrypted using Transport Layer Security (TLS 1.3). For client-side operations, tool inputs and outputs remain in browser memory, and closing your browser tab purges transient data from local memory.
