Go Toolstack
🔒 100% Client-Side Privacy Guarantee

Privacy Policy

Last Updated: September 12, 2026 • Effective Date: January 1, 2025

1. Overview & Core Privacy Commitment

At GoToolstack (accessible at gotoolstack.com), your privacy is our highest priority. Unlike traditional web services that upload your files, spreadsheets, text documents, or calculations to remote cloud servers for processing, GoToolstack is built from the ground up on a 100% client-side execution architecture.

Every calculation, file conversion, PDF modification, image blur, code formatting, and cryptographic operation is executed strictly within your local browser sandbox using modern web standards (WebAssembly, HTML5 Canvas 2D, and Web Crypto API). Your tool inputs and files are processed in your browser and never uploaded to GoToolstack servers.

2. Information We Do NOT Collect

Because of our client-side architecture, we do not have access to, collect, or store:

  • Uploaded Files, Documents & Tool Inputs: All files and inputs are processed locally within your browser sandbox without ever being uploaded to GoToolstack servers. Runtime memory is managed by your browser's standard lifecycle and garbage collection. In tools offering optional draft saving, content is stored on your device only upon explicit opt-in, is kept for a limited duration (24 hours), and can be cleared at any time.
  • Financial & Personal Inputs: Values entered into our loan, mortgage, tax, salary, or investment calculators never leave your client device.
  • Passwords & Keys: Passwords entered in our PDF Password Protector or encryption tools are consumed locally by the browser engine and are never transmitted over the network.

3. Distinct Data Streams & Infrastructure Access Logs

To maintain strict transparency and prevent confusion, we clearly separate our client-side tool execution from operational data flows. We do not make misleading blanket claims of "no logs or no cookies across the website". GoToolstack distinguishes the following separate data streams:

  • Tool Inputs & File Processing (100% Client-Side): Your tool inputs, parameters, and uploaded files are processed strictly in your local browser sandbox and are NEVER uploaded to or stored on GoToolstack servers.
  • Hosting & CDN Network Access Logs: Standard HTTP request data (including IP address, browser user-agent, referring URL, and access timestamps) is automatically logged by cloud hosting and CDN infrastructure strictly for network routing, DDoS mitigation, and system security.
  • Contact & Support Inquiries: Communications voluntarily submitted via our contact form or support email (such as name, email address, and message content) operate as a separate data stream solely to respond to your inquiries.
  • Local Storage, Optional Drafts & Third-Party Cookies: Browser localStorage is used for non-personal interface preferences (e.g., currency, theme) and user-consented temporary local drafts with automatic 24-hour expiration. Tool content is never shared with advertisers. Completely separate from local tool execution, third-party advertising networks (such as Google AdSense) use cookies to keep our tools free, as detailed in Section 4 below.
  • Third-Party Public API Lookups & Remote Speech Voices (Optional & Transparent): While core utility computations run client-side, specific external lookup tools (such as Islamic Prayer Times querying the public Aladhan API) transmit only user-selected city or GPS coordinates directly to that endpoint with explicit user consent. In the Text-to-Speech (TTS) tool, local system voices process text entirely on-device; if optional network/remote voices are explicitly enabled and selected, text may be processed by external cloud speech providers (e.g. Google or Microsoft). A client-side WAV audio export is provided for offline audio generation. No files, passwords, or personal identity profiles are ever attached to these requests.
  • Consented Operational Telemetry & Diagnostics: When you provide explicit consent for analytics, coarse operational signals (such as tool start, success, coarse duration, sanitized error codes, and download format) may be recorded to detect defects and maintain performance. These diagnostics strictly filter out and never record file contents, filenames, user inputs, regex expressions, passwords, or financial amounts.

4. Google AdSense & Third-Party Advertising Cookies

GoToolstack is configured with the Google AdSense infrastructure (Publisher ID: pub-4565813603643012) to sustainably maintain free tools, and displays advertisements via Google and affiliated third-party advertising partners when active and in accordance with user consent. In compliance with Google's advertising policies and the European Union User Consent Policy, we disclose the following:

  • Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites on the internet.
  • Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to GoToolstack and/or other sites on the Internet.
  • Users may opt out of personalized advertising by visiting Google Ads Settings. Alternatively, you can opt out of third-party vendors' use of cookies for personalized advertising by visiting www.aboutads.info.

5. European General Data Protection Regulation (GDPR) Compliance

If you are a resident of the European Economic Area (EEA), you have specific rights under the 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 request that we correct any information you believe is inaccurate.
  • Right to Erasure: You have the right to request that we erase your personal data under certain conditions.
  • Right to Restrict Processing: You have the right to request restriction of processing of your personal data.

Because GoToolstack does not store user accounts or personal profiles, the vast majority of our services hold zero personal identifiers. For any GDPR-related inquiries or data requests, please contact us at [email protected].

6. California Consumer Privacy Act (CCPA / CPRA) Compliance

Under the California Consumer Privacy Act (CCPA) and California Privacy Rights Act (CPRA), California residents have the right to know what personal data is collected and to request its deletion. GoToolstack does not sell, rent, or trade your personal information to any third party for monetary or other valuable consideration.

7. Children's Online Privacy Protection Act (COPPA)

GoToolstack does not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13. If you are a parent or guardian and you are aware that your child has provided us with personal information, please contact us immediately.

8. Changes to This Privacy Policy

We may update our Privacy Policy periodically to reflect changes in our legal obligations or technical architecture. Any updates will be posted on this page with a revised "Last Updated" timestamp. We encourage you to review this page periodically.
