Most tools process input entirely in your browser. Your data stays on your device unless a tool page explicitly states that it uses server-side logic—for example, generating sample Italian fiscal codes or random people records.
Favorites are stored in your browser localStorage on this device only. We do not sync favorites to our servers. Open the Favorites page or the menu panel to see saved tools. Clearing site data removes them.

No. BMI, heart-rate, mortgage, and similar tools provide educational estimates only. Each health tool includes a disclaimer in its user guide. Do not use results for diagnosis, treatment, or investment decisions.
Tool Plaza is agentic-first—most utilities are A2A skills. Use the Agent API page for A2A JSON-RPC and REST execute, or open any programmatic skill page for ready-to-run examples (no discovery required). Per-skill schemas live at GET /api/helpers/{skillId}. Server-side API calls log aggregate usage only—not your request arguments.
A2A (Agent-to-Agent) is the JSON-RPC protocol agents use to call Tool Plaza skills via POST /api/a2a. You can also use the REST execute API. Browser-only tools such as timers and media converters are not exposed as execute skills.
Open a tool family hub such as /en/tools/base64 or /en/tools/iban. Multi-tool hubs include long-form documentation above the subtool list. Single-subtool tools show that hub article on the tool page itself.
No. Those tools produce sample values for software testing, demos, and QA fixtures. They are not issued by banks or government authorities and must not be used for real financial transactions or identity claims. Each page shows an amber test-data disclaimer banner when applicable.
Health, financial, legal, security, entertainment, and sample/test-data tools show the same amber disclaimer banner above the user guide. The notice text comes from the tool’s documentation disclaimer sections so reviewers and users see intended use immediately.
Yes. Educational articles live on tool hub pages (for example /en/tools/hashing or /en/tools/bmi) and on each subtool’s user guide above the form—on toolplaza.app, not only on third-party blogs.
