Terms of Service

Using the service

You may use Hidden Character Detector for lawful personal, educational, editorial, research, and development work. You are responsible for the text you choose to inspect and for checking that any cleanup is appropriate for the language, document, and system where you plan to use it.

Free limits

The first release accepts up to 2,000 Unicode characters per check and provides 20 browser-tracked free checks per UTC day. The local counter is intended to manage normal use and may be reset by clearing browser storage. We may adjust limits as the service changes.

Results and limitations

The detector uses an explicit list of Unicode definitions. A character that is not on that list may not be reported. A reported character may be legitimate in multilingual, typographic, or file-encoding contexts. The service does not determine authorship, identify AI-generated text, prove a watermark, or provide legal, academic-integrity, security, or forensic conclusions.

Cleaning responsibility

Remove All creates a transformed copy. It removes selected zero-width and formatting controls, normalizes selected Unicode spaces to regular spaces, and normalizes line separators to line breaks. Review the output before publishing, storing, or sending it. Keep the original when the source may require an exact record.

Acceptable use

You must not use the service to violate law, rights, privacy, or the security of another person or system. You must not overload the service, automate abusive traffic, attempt to bypass infrastructure protections, or misrepresent the result as proof of a person's identity, intent, or authorship.

Availability and changes

The service is provided on an evolving basis. Features may be changed, limited, or temporarily unavailable. Pro features and Waffo checkout are placeholders in this release; no paid entitlement is created by clicking the Upgrade to Pro button.
