Security
At CleverTools we take your data security seriously. This page describes the measures we take to protect your information.
The measures we take
Data protection
All data processed through our platform is handled securely with encryption during transfer and storage.
Secure connections
We use HTTPS and other security protocols to ensure a safe browsing and document processing experience.
Account security
Users are encouraged to use strong passwords and keep their accounts confidential. We are not responsible for compromised accounts due to weak credentials.
How browser-based processing protects your data
CleverTools is intentionally architected so your files never leave your device. Every tool (PDF compressor, Word converter, GST invoice generator, image resizer, OCR engine, hash generator, and so on) runs as JavaScript and WebAssembly inside your browser tab. When you drag a file into a tool, the bytes are loaded into the tab's memory, the conversion runs locally on your CPU, and the output file is offered as a download directly from your browser. At no point in this flow is the file uploaded to a server, written to disk on our infrastructure, queued for processing, or scanned by us.
This is fundamentally different from how most online tool websites operate. Typical "upload and convert" sites send your file to a backend, run the conversion there, store the result for some retention window, and email or download it back. Even when those sites claim to delete files after an hour or a day, your sensitive document, whether an Aadhaar PDF, a salary slip, a signed contract or a tax return, has briefly lived on someone else's server. With CleverTools that risk window does not exist, because the upload itself never happens.
What we explicitly do not do
- No file uploads: processing happens 100% in your browser tab.
- No accounts or login: there is nothing to register, nothing to leak.
- No file logs or analytics on file content: the tools have no API endpoint that receives your file.
- No third-party file processing: conversions run on first-party JavaScript libraries (pdf-lib, pdfjs-dist, jsPDF, mammoth, and similar) bundled into the tool.
- No watermarks or trial gates: output files contain your data only.
What we do collect, and how to reach us
Like most websites, CleverTools logs anonymous web analytics (page views, country-level location, browser type and referrer) to understand which tools are popular and where to invest. None of this analytics data includes the contents of files you process. For complete details, see the privacy policy.
