Off Cloud by Design principles
Off Cloud by Design favors local processing, avoids unnecessary uploads, and explains clearly how each tool handles data.
Quick answer
Off Cloud by Design builds small browser tools intended to process the values a user enters on-device whenever technically possible. The browser still requests the page and its code; local processing describes what happens to the values entered into the tool.
Local processing
Tool pages explain where processing happens and include practical ways to inspect network activity. Some browser capabilities or file formats can limit what runs locally; check the relevant tool page.
What reaches a server?
Your browser requests the page and its code, so the hosting infrastructure receives ordinary web requests. The tools in this catalogue are designed to handle entered values and produce results in the browser; those values are not sent as part of the tool calculations.
Optional usage analytics
Google Analytics (measurement ID G-45Z9PH2L6P) loads only if you choose “Allow analytics”. It then receives visit and page-view information to measure use of the site; tool inputs and results are not included in the calculations sent to analytics. You can refuse or change your choice with “Analytics settings” in the footer. The choice is stored in this browser for 180 days. See Google’s privacy information for how Google handles data.
Data minimisation
Tools should request only the values needed for the task. Avoid entering personal or confidential details when a calculator can work with anonymous numbers.
Clear limits
A local calculation can still be wrong, incomplete, or unsuitable for a regulated decision. Security estimates are simplified, and professional calculators do not replace legal, financial, or medical advice.
Check for yourself
Use fictional sample values, then inspect your browser’s network panel while you interact with the tool. The request may load page assets; check whether your sample values appear in any request.
