Privacy Policy

Overview

OG Online Ruler is designed to work without an account and without uploading the objects you measure. This policy explains what information the website uses and what remains on your device.

Information stored on your device

The ruler uses browser local storage to remember preferences such as measurement units, active ruler edges, display calibration, and theme. This information stays in your browser unless you clear site data. It is not a user profile and does not include the physical objects you measure.

Device and screen information

Calibration may use values supplied by your browser, including screen width, screen height, and device pixel ratio. These values are processed in the page to estimate scale. Automatic detection compares the values with known display profiles. OG Online Ruler does not need camera, microphone, precise location, or contact access.

Server logs and hosting

Like most websites, our hosting provider may process standard request information needed to deliver and protect the service. This can include an IP address, browser type, requested URL, time, and diagnostic or security logs. Retention and handling may depend on the hosting provider used to operate the site.

Analytics

We use Google Analytics to understand aggregated website usage, such as pages viewed, approximate region, device category, browser type, and interactions with the tool. Google may process identifiers and set or read cookies where permitted. We use these reports to find broken experiences, understand which features are useful, and maintain the website. We do not use Analytics to identify the physical objects you measure.

You can restrict analytics through browser privacy settings, cookie controls, content blockers, or Google’s Analytics opt-out tools. Google’s handling of Analytics data is governed by its own privacy terms.

Data sharing and retention

We do not sell personal information. Local ruler preferences remain until you clear them through browser settings. Infrastructure logs may be retained temporarily for reliability, abuse prevention, and security. Aggregated analytics and service data may be processed by Google Analytics and our hosting provider only as needed to provide, secure, and improve the website.

Your choices

You can use private browsing, block local storage, or clear site data at any time. Blocking storage may prevent the ruler from remembering calibration and theme preferences between visits.

Children and changes

The service is a general utility and is not designed to collect personal information from children. We may revise this policy when the tool or legal requirements change. The latest revision date appears above.
