Privacy Policy

TL;DR

• We don't require accounts. There's nothing to sign up for.
• Tools run in your browser. Your inputs don't leave your device unless you submit a form.
• We use privacy-respecting analytics (page counts, no individual tracking).
• Your email — if you give it — is used only for the newsletter or to reply to you.
• We don't sell, rent, or share your data with third parties.

Information we collect

We collect the minimum needed to run the site:

• Tool inputs — values you enter into a calculator are processed in your browser. We do not transmit or store them.
• Email address — only if you submit the contact form or newsletter signup.
• Anonymous usage stats — page views, referrer, country (no IP stored), browser type. This helps us understand which tools matter and which articles to write next.
• Cookies — see the cookies section below.

How we use your information

• To respond to your message (contact form).
• To send newsletter updates you have opted into.
• To improve the site — fix bugs, add tools you actually use.
• To meet any legal obligations.

We never use your data for personalised advertising or behavioural profiling.

Cookies

We use a minimal number of cookies:

• Essential cookies — required for the site to function (e.g. remembering your dark/light theme preference).
• Analytics cookies — anonymous, aggregated visit data via a privacy-respecting analytics provider.

You can disable cookies in your browser settings, but parts of the site may not work as expected.

Third-party services

We use a small number of third-party services to operate the site:

• Web hosting — to serve the site.
• Email delivery — for newsletter and contact replies.
• Analytics — for anonymous usage stats.

Each is bound by their own privacy policy. We choose providers that align with our privacy-first approach.

Your rights

You have the right to:

• Request a copy of any personal data we hold on you.
• Request correction or deletion of your data.
• Withdraw consent for the newsletter at any time (unsubscribe link in every email).
• Lodge a complaint with your local data protection authority.

Email szrg411@gmail.com for any of the above. We respond within 30 days.

Data retention

Contact form messages are kept for 12 months unless an ongoing conversation requires longer. Newsletter emails are kept until you unsubscribe. Anonymous analytics are retained for 26 months.

Children's privacy

AQZTools is intended for general audiences. We do not knowingly collect data from children under 13. If you believe a child has submitted personal data, contact us and we will delete it.

Changes to this policy

If we materially change this policy, we will update the "last updated" date and, where appropriate, notify newsletter subscribers. Continued use of the site after a change constitutes acceptance.
