Privacy

Local numbers, explicit actions.

Falloffnote processes the old distance, new distance and common unit in JavaScript in the open page. It does not deliberately upload them to a calculation service, add them to the page address or turn them into analytics events. No analytics, advertising or consent-platform loader is active in this source release. Prepared publisher metadata and ads.txt are not active advert delivery or proof of approval.

What is kept in the page

The page holds current input and results in memory while it is open. It does not deliberately store those values in cookies, local storage or session storage. Startup explicitly replaces browser-restored fields with the fixed 1.5-to-2.25-metre example. Reset example restores the same values. Editing either distance or the common unit immediately clears previous results, diagram labels and exports until the user calculates again.

Your browser and operating system may manage their own history, form restoration, clipboard and downloaded-file records. This website cannot control those independent features. Closing a page does not remove a result you saved, copied or shared elsewhere.

Copy and downloads

Copy notes requests clipboard writing only after you choose that button. If permission or browser support is unavailable, a visible manual-copy field provides the current notes. Save text and Save JSON create local downloads containing the current inputs, fractions, approximate values and model scope. These actions do not intentionally send a result to a server. Delayed clipboard responses are ignored after an edit or reset so they cannot revive stale notes.

Hosting and email

Delivering the page involves ordinary hosting requests. The hosting service may receive connection details such as an IP address, time, requested path and browser information. Local calculation does not eliminate those requests. This page does not request a location, camera, light sensor or file access.

Contact email is separate from the calculator. The shared public forwarding alias uses external mail services, and a message may be retained while a correction is investigated. Include only what is needed to reproduce the issue. This page does not control your mail provider’s retention or the independent records managed by your device.
