ROBERIN Operating Policy
This page explains the principles ROBERIN follows to run its tools, how it treats results, and how it handles advertising, copyright, privacy, and contact. Calculations and conversions are for reference only; official sources and your own verification always take priority for final decisions.
Free, no sign-up
Most tools stay usable right away, with no account or payment required.
Results are a reference
Calculated and converted values are helpful estimates, not a substitute for legal, medical, or financial judgment.
Fixed through feedback
We improve often and in small steps, guided by reports and how the tools are actually used.

How ROBERIN operates
ROBERIN is a tools site that gathers the everyday jobs you want to finish right in your browser: quick calculations, unit conversions, date checks, and image or document work. This operating policy collects, in one place, the standards worth knowing when you use the service.
This policy may change as the service improves, and important changes are reflected on this page. The last updated date is shown at the bottom of the document.
Free web tools you can use without signing up
Reference estimates, not professional advice
Ads for running costs that never block the flow
Reported, verified, then fixed
Using the service and accounts
ROBERIN tools are designed to be used without creating an account. Some features may store settings or favorites in your browser; these stay on your device and are not sent to our servers. Activity that goes beyond normal use — such as automated bulk requests, disrupting the service, or infringing intellectual property rights — may be restricted.
Accuracy of results and disclaimer
Calculators and converters run on commonly accepted formulas and assumptions, and their output is an estimate for reference. In regulated areas such as tax, payroll, law, health, or finance, the actual rules, product terms, and official sources from the relevant authority take priority. Before making an important decision, always confirm with official sources and a qualified professional. ROBERIN is not liable for any direct or indirect damage arising from the use of results.
Tool development and AI use
Roberin uses AI to assist with coding, draft explanations, and translation. An AI response is not treated as evidence of accuracy. Calculations and features are checked by comparing independently worked-out examples with the actual results and behavior.
Formulas, sources, examples, scope, and limitations belong in each tool’s explanation. The update date of this operating policy does not mean that every tool’s calculation basis was checked again on that date.
Translation and review limits
We use AI for translation and check that interface wording, terminology, units, and examples fit the tool’s stated basis. Not every language version has been reviewed by a native speaker or a subject-matter expert, and errors may remain. Changing the language does not automatically change the calculation to a particular country’s system. Check each tool’s explanation for its applicable basis.
Advertising policy
Keeping the tools free requires server and maintenance costs, and advertising is how those costs are covered. Even so, we arrange ads so they do not hide the calculation flow or appear before the buttons you actually need. Advertising providers (third parties such as Google AdSense) may use cookies and similar technologies to serve relevant ads; please also review our privacy policy for how this is handled.
Copyright and content use
Rights to ROBERIN’s tools, text, design, and logo belong to ROBERIN or the rightful owners. You are free to reference the screens or use the results for personal, non-commercial purposes, but reproducing or redistributing the site’s structure or content, or using it commercially, is not allowed without prior consent. Where external material is cited, the source is shown within each tool.
Protecting your privacy
ROBERIN aims to handle only the minimum information necessary. For details on what is collected, why, how long it is kept, and your rights, see the Privacy Policy.
