Frequently Asked Questions

Common questions about Allio Tools, our tools, and how we handle your data.

What is Allio Tools?

Allio Tools is a free, browser-based utility platform with 176+ tools covering financial calculations, image processing, text manipulation, developer utilities, web diagnostics, health calculators, date and time tools, and more. Every tool runs entirely in your browser — no account required, no file uploads to servers, no usage limits.

Are all tools on Allio Tools really free?

Yes. All 176+ tools are completely free to use with no sign-up, no payment, and no usage limits. There is an optional Pro subscription that removes ads and unlocks bulk-processing features, but every core tool function is available free.

Is my data safe when I use these tools?

Yes. All tools process your data entirely in your browser using JavaScript and browser APIs. Nothing you type, paste, or upload is sent to any server, logged, or stored anywhere. For image tools, your files never leave your device. For network tools (like DNS lookup), only the query — not your input context — is sent to the relevant API endpoint.

Do I need to create an account?

No. Every tool works instantly without an account. An optional account lets you sync your favourites across devices, but all core tool functionality is available without signing up.

Do the tools work offline?

Most tools work offline after the page has loaded once, because they use no external APIs. Tools that require live data — such as the Currency Converter, DNS Lookup, and IP Address Lookup — need an active internet connection to fetch real-time results.

What browsers are supported?

All tools work on modern versions of Chrome, Firefox, Safari, and Edge — on both desktop and mobile. No plugins, extensions, or browser flags are required. Tools that use advanced browser APIs (like WebCrypto for hashing) require a browser from 2020 or later.

Do the tools work on mobile and tablet?

Yes. Every tool is designed to be fully usable on smartphones and tablets. The layout adapts to small screens. For complex tools (like the JSON Formatter), a landscape orientation or larger screen gives a better experience.

How many languages does Allio Tools support?

Allio Tools is available in 11 languages: English, Chinese (Simplified), Spanish, Arabic, Indonesian, Portuguese, French, Japanese, Russian, German, Hindi. Use the language switcher in the top-right corner, or navigate to /allio.tools/[lang]/ (e.g., /es/ for Spanish).

How accurate are the calculators?

Financial calculators use standard amortization and compound interest formulas consistent with Microsoft Excel and CFPB guidelines. Health calculators use peer-reviewed formulas from the WHO, CDC, and ACSM. All formulas are documented on our Methodology page. Results are estimates — always verify important decisions with a qualified professional.

Can I embed a tool on my website?

Yes. Every tool page includes an embed widget (click the </> button below the tool). Copy the provided iframe code and paste it into your web page. The tool is free to embed with attribution — the link back to Allio Tools must remain in the embed code.

Does Allio Tools have an API?

Not a public REST API — but the site exposes a machine-readable tool index at /search-index.json and an LLM-friendly directory at /llms.txt. Each tool URL is stable and can be deep-linked or embedded.

How do I report a bug or incorrect result?

Please use the contact form. Include the tool name, the input you used, the result you received, and — if possible — what the correct result should be with a reference. We investigate every report and fix verified formula errors within 48 hours.

Can I suggest a new tool?

Yes — we read every suggestion. Use the contact form and describe the tool you'd like, what problem it solves, and how often you'd use it. Popular requests are prioritised for development.

Does Allio Tools use cookies?

We use minimal browser storage. Favourites, theme preference, and recently viewed tools are stored in your browser's localStorage (not cookies). Analytics use Google Analytics 4 cookies in anonymised mode. See our Cookie Policy for details.

How is Allio Tools funded?

Allio Tools is supported by optional Pro subscriptions and minimal, non-intrusive advertising via Google AdSense. We will never introduce paywalls for standard tool access, require registration for free features, or sell user data.
