Privacy Policy
Last updated: January 11, 2025
This Privacy Policy explains how the online protractor collects, uses, and protects your information. We are committed to protecting your privacy and being transparent about our data practices. Your privacy is our priority.
Information We Collect
The online protractor is designed with privacy in mind. We do not collect personal information unless you voluntarily provide it when contacting us. The tool operates entirely in your browser - your uploaded images, measurements, and workspace data are stored locally on your device using browser local storage. We do not have access to this data, and it is never transmitted to our servers. We may collect anonymous usage statistics (such as page views and feature usage) through standard web analytics to help us improve the tool, but this data cannot be used to identify you personally.
How We Use Your Information
If you contact us via email, we use your email address and message content solely to respond to your inquiry and improve our service based on your feedback. We do not use your email for marketing purposes, and we do not share it with third parties. Anonymous usage statistics help us understand which features are most used and where improvements are needed. Your workspace data (protractors, measurements, images) remains on your device and is used only by you for your measurement tasks.
Data Storage and Security
All measurement data, uploaded images, and workspace settings are stored locally in your browser using the Web Storage API (localStorage). This data persists between sessions but remains on your device. We do not store this data on our servers. You can clear this data at any time by clearing your browser's local storage or using your browser's privacy settings. If you export your workspace as JSON, that file is saved to your device and is under your control. We implement industry-standard security measures for our website, including HTTPS encryption for all connections.
Cookies and Tracking
We use minimal cookies necessary for the website to function properly, such as storing your language preference and theme choice (light/dark mode). We may use analytics services (such as Google Analytics) to collect anonymous usage data. These services may use cookies to track page views and user interactions. You can disable cookies in your browser settings, though this may affect some functionality. We do not use cookies for advertising or tracking you across other websites.
Third-Party Services
Our website may use third-party services for analytics and hosting. These services have their own privacy policies and may collect data according to their terms. We do not share your personal information with third parties for their marketing purposes. If you upload images to the tool, they are processed entirely in your browser and are not sent to any third-party services. Links to external websites (if any) are not under our control, and we are not responsible for their privacy practices.
Your Rights and Choices
You have the right to access, correct, or delete any personal information you have provided to us (such as email correspondence). You can clear all locally stored data by clearing your browser's local storage. You can opt out of analytics tracking by using browser extensions or privacy settings. If you are in the European Union, you have additional rights under GDPR, including the right to data portability and the right to object to processing. To exercise these rights or if you have questions about your data, contact us at [email protected].
Children's Privacy
Our service is designed to be safe for users of all ages, including students. We do not knowingly collect personal information from children under 13. The tool does not require registration or account creation, so children can use it without providing any personal information. If you are a parent or guardian and believe your child has provided us with personal information, please contact us so we can delete it.
Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in our practices or legal requirements. We will post the updated policy on this page with a new 'Last Updated' date. Continued use of the service after changes constitutes acceptance of the updated policy. For significant changes, we may provide additional notice on our website.
Contact Us
If you have questions about this Privacy Policy or our data practices, please contact us. We will respond to your inquiry as soon as possible.
