Privacy & security
The Word Frequency Counter is designed with privacy as a hard constraint, not an afterthought:
- No upload: Your data is processed in your browser's JavaScript engine. No HTTP request is made to any server while you use the tool.
- No account required: The tool works instantly — no email, no sign-up, no cookie consent wall.
- No logging: Calabi does not log what you paste, upload, or generate. The server only delivers the HTML/JS page — it never sees your content.
- Open to inspection: Open your browser's network inspector while using the tool. You'll see zero outbound requests related to your data.
This architecture is particularly important for the Text category of tools, where the inputs often contain sensitive or proprietary information.
