Privacy Policy

Spirit Level is an independent browser-based measuring tool. This policy explains the information used by the tool and by the services that deliver it. For privacy questions, email ankitchauhan3296@gmail.com.

Measurements and device permissions

Orientation readings are processed in your browser to move the bubble and calculate angles. The tool does not send these readings to a measurement database. Motion access is requested where your browser requires it. Calibration offsets and held readings are kept in page memory and are cleared when the page is reloaded.

Saved readings and browser storage

If you choose Save, up to ten measurements, their mode, placement and time are stored in local storage on your device. They remain until you use Clear or remove this website’s browser data. Other people using the same browser profile may be able to see them. The tool does not add advertising cookies or analytics scripts. Hosting or sign-in services may use their own cookies or storage.

Optional voice control

Voice control requests microphone access and uses your browser’s speech recognition service. Depending on the browser, audio may be processed by its speech provider online. Spirit Level does not store recordings or transcripts. Disable Voice control, say “stop listening,” or revoke microphone permission to stop using this feature. Your browser and its speech provider govern any processing they perform.

Hosting and fonts

The hosting platform and its infrastructure providers may process IP addresses, request times, browser information and security logs to deliver and protect the website. The page loads fonts from Google Fonts; your browser sends network information, including your IP address, when requesting those files. Those providers apply their own privacy policies and retention practices. If this hosted version requires sign-in, that process is managed by the hosting platform.

When you contact us

Emailing us shares your address and whatever you include in the message with the site operator and the email providers involved. We use that information to respond, investigate reported problems and handle privacy requests. Please avoid sending passwords, payment details or sensitive personal information. Correspondence should be kept only as long as needed for the inquiry and any applicable obligations; you can ask us to delete it.

Your choices

You can use the visual tool without voice control, withdraw browser permissions, clear saved readings and stop using the site. Depending on applicable law, you may also have rights to access, correct, delete or restrict use of personal information, and to complain to your local privacy authority. Send requests to the contact address above. We cannot remotely retrieve measurements stored only in your browser.

Changes

We may update this policy when the tool or its data practices change. The date above identifies the latest revision.
