Trendalyzer is a static website of free, unlimited, useful tools that run in your browser. Your files stay on your device. It is published at trendalyzer.app and contacted at info@trendalyzer.app. There are no user accounts and no server-side document store.
Who publishes this site
Trendalyzer is an independent tools site. The public contact for the publisher is info@trendalyzer.app. Editorial and product questions, privacy requests, and accessibility feedback all go to that address. We do not run a telephone support line or a ticket portal.
The site is written and reviewed as product documentation, not as legal, medical, financial, or tax advice. If a page looks like a how-to, it is describing how this tool behaves in a browser.
Experience we actually have
The work here is browser engineering and catalogue design:
- PDF merge, extract, rotate, crop, and standard text forms, running with pdf-lib in the page
- Document-to-Markdown conversion for DOCX, HTML, text, and text-native PDFs
- Eighty-eight chart generators with local SVG, PNG, and Excel data export
- Text encode, format, and inspect helpers with goldens on the path the browser actually runs
We do not claim clinical, legal, or fiduciary expertise. Tools that would require that expertise are out of scope.
What “browser-local” means here
It means something specific and testable, not a marketing line:
- Supported tools do not upload your files to any external processing server.
- There is no account, and no file storage.
- Every tool has an automated browser test that performs a full input-to-output cycle and asserts that the file contents never appear in a network request. If that assertion ever fails, the build fails.
The page may later load signed, allowlisted third-party hosts (for example ads). Those hosts are not allowed to receive your file. Ordinary hosting logs (IP address, requested URL) still exist, as they do for any static site. See the privacy policy.
Limits worth knowing
- Large files are processed in a Web Worker with a visible cancel control, but very large documents are still bound by your device’s memory.
- Document conversion is best-effort for layout-heavy files. Check the output.
- Scanned or image-only PDFs cannot be converted to text; there is no local OCR yet.
What this site does not do
No file uploads for supported local workflows. No cryptographic signing or certificate handling. No AI analysis of your documents. No telemetry containing filenames, document text, chart data, labels, or exported content.
