Privacy Policy

1. Introduction

Aspect Ratio Calculator (“we”, “us”, or “our”) operates aspect-ratio-calculator.com (the “Service”). This Privacy Policy explains how we collect, use, and protect information when you use our Service.

We are committed to protecting your privacy. This tool is designed to work with minimal data — the calculator runs entirely in your browser and we do not store your calculation inputs or results.

This Privacy Policy complies with the Privacy Act 1988 (Cth) and the Australian Privacy Principles (APPs). If you have any concerns, please contact us using the feedback widget on the calculator page.

2. Information We Collect

Information we do NOT collect

• No account registration or login is required
• Your calculation inputs (dimensions, ratios, images) are processed locally in your browser and never transmitted to our servers
• We do not store any personal identification information
• We do not sell, trade, or rent your data to third parties

Anonymous analytics

We use Vercel Analytics to collect anonymous, aggregated data about how the Service is used. This includes page views, general geographic region (country level only), device type, and referring source. Vercel Analytics does not use cookies, does not fingerprint your browser, and does not collect personally identifiable information (PII).

Feedback form

If you voluntarily submit feedback through our feedback widget, we collect the content of your message and, if provided, your email address. This information is used solely to respond to your feedback. It is transmitted via Resend (a transactional email service) and is not shared with any other third party.

3. Cookies & Local Storage

We do not use tracking cookies or advertising cookies. Your theme preference (light or dark mode) may be stored in your browser's localStorage so that it persists across visits. This data stays on your device and is never transmitted to us.

If you install the Service as a PWA (Progressive Web App), a service worker is registered in your browser to enable offline functionality. The service worker caches application assets only; it does not collect or transmit any personal data.

4. Third-Party Services

The Service uses the following third-party services:

We are not responsible for the privacy practices of these third-party services. We encourage you to review their individual privacy policies.

5. Your Privacy Rights

Under the Australian Privacy Principles, you have the right to:

• Request access to any personal information we hold about you
• Request correction of any inaccurate personal information
• Request deletion of any personal information you have voluntarily provided (e.g., via the feedback form)
• Lodge a complaint with the Office of the Australian Information Commissioner (OAIC) at oaic.gov.au if you believe we have breached your privacy

To exercise any of these rights, please contact us via the feedback widget on the calculator page.

6. Data Retention

Feedback form submissions (including any email address you provide) are retained for a maximum of 90 days, after which they are permanently deleted. Anonymous analytics data (aggregated page view counts) may be retained indefinitely as it contains no personally identifiable information.

7. Children's Privacy

The Service 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 has provided us with personal information, please contact us and we will take steps to delete it promptly.

8. International Users

The Service is operated from Australia. If you are accessing the Service from outside Australia, please be aware that your information may be processed in Australia and other countries where our service providers operate. By using the Service, you consent to the transfer of your information to countries outside your country of residence, which may have different data protection rules.

9. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or for legal, operational, or regulatory reasons. When we make changes, we will update the effective date at the top of this page. We encourage you to review this policy periodically. Continued use of the Service after changes are posted constitutes your acceptance of the updated policy.

10. Contact Us

If you have questions, concerns, or requests regarding this Privacy Policy or our data practices, please use the feedback widget on the calculator page. We are based in Australia and aim to respond to all privacy enquiries within 30 days, as required by the Australian Privacy Principles.
