Privacy Policy

1. Overview & Core Commitment

At Toolstack (accessible from https://toolstack.tools), user privacy is our foremost priority. We design and operate our web utilities so that your data, text strings, converted files, and calculations remain on your device.

2. Local Browser Processing (Zero Data Collection)

All interactive utilities—including the Base64 Decoder & Encoder, JSON Validator & Formatter, URL Encoder & Decoder, Tip Calculator, and HEIC to JPG Converter—execute entirely within your web browser using JavaScript and WebAssembly.

• Your text inputs, passwords, or API keys are never transmitted to our servers.
• Your photos and HEIC files are converted locally in memory and never uploaded.
• We do not log, retain, or share the content you process with any tool.

3. Cookies & Advertising Partners

Toolstack may display advertisements served by Google AdSense or other reputable advertising networks. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to our website or other websites on the internet.

Users may opt out of personalized advertising by visiting Google Ads Settings or through aboutads.info.

4. Web Analytics & Log Files

Like most websites, our web hosting infrastructure may record standard technical log entries (such as IP addresses, browser types, internet service providers, referring/exit pages, and timestamps) solely for server maintenance, DDoS prevention, and traffic diagnostics. These logs do not contain any data entered into our tools.

5. GDPR (DSGVO) & CCPA Rights

If you reside in the European Economic Area (EEA) or California, you are entitled to statutory rights regarding your personal data. Because Toolstack does not store personal data entered into utilities or require user accounts, we hold no user profiles to inspect, export, or delete.
