ToolStack ("we", "us", "our") operates the website at toolstack.com and its associated tool pages. ToolStack provides free browser-based utility tools to the public at no charge.
This Privacy Policy explains how we collect, use, and protect information when you visit our website. By using ToolStack, you agree to the terms described in this policy.
The only personal information we actively collect is what you voluntarily submit via our Contact form — specifically your name, email address, and message. This is used solely to respond to your enquiry.
When you visit ToolStack, standard web analytics data is collected automatically. This includes:
This data is anonymised and aggregated. It cannot be used to identify you personally and is used only to understand how people use our site so we can improve it.
Every tool on ToolStack — ToolStack, ToolStack, ToolStack, ToolStack, ToolStack, ToolStack, and ToolStack — is built to run entirely client-side. This is a deliberate architectural decision, not a marketing claim.
"Client-side" means all processing occurs in your web browser on your own device. When you type a password into ToolStack, generate an invoice in ToolStack, or enter your weight into ToolStack, that data never leaves your device and never touches our servers.
You can verify this yourself: disconnect your internet connection after a page loads and most tools will continue to function normally, because they require no server communication.
Downloaded files (such as PDF invoices or QR code images) are generated locally in your browser and saved directly to your device. We do not receive copies of these files.
ToolStack itself uses minimal cookies — primarily for analytics (see Section 5) and to remember any site preferences you set. We do not use tracking cookies for profiling or behavioral targeting.
ToolStack is supported by advertising through Google AdSense. Google may use cookies and similar technologies to serve ads based on your prior visits to ToolStack and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and/or other sites on the internet.
You can opt out of personalised advertising by visiting Google's Ads Settings or by visiting aboutads.info. You may also opt out via your browser's cookie settings, though this may affect your experience on other websites.
We use analytics software to collect anonymous traffic data as described in Section 2. This may set a cookie to distinguish unique visits. No personally identifiable information is stored in analytics cookies.
ToolStack uses the following third-party services that may collect data according to their own privacy policies:
We do not sell, rent, or share your information with any other third parties beyond those listed above. We do not use data brokers, remarketing platforms, or social media tracking pixels.
Contact form submissions (name, email, message) are retained for up to 12 months for the purpose of correspondence, then deleted.
Anonymous analytics data (page views, country, browser type) may be retained indefinitely in aggregated form, as it contains no personal information.
Since we do not collect tool usage data, there is no tool data to retain or delete.
Depending on where you live, you may have certain rights regarding personal data. Under the EU General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA), these include:
Since the only personal data we may hold is information from contact form submissions, requests to access or delete your data will typically be straightforward. To exercise any of these rights, contact us at the details in Section 10.
ToolStack is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has submitted personal information to us via our contact form, please contact us immediately and we will delete it.
We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. Significant changes will be noted prominently on the homepage or in our tools.
Continued use of ToolStack after changes to this policy constitutes acceptance of the revised terms. We encourage you to review this policy periodically.
For any privacy-related questions, data requests, or concerns, please reach out through our contact page.
We're happy to clarify anything in this policy or address a data request.
