Privacy

Last updated: 15 May 2026

tools.sreecharan.in (the "site", "we", "us") takes privacy seriously. This page explains what data is collected, by whom, and what your rights are.

Summary in plain English

• The files you upload to a tool on this site are never sent to our server. They are processed entirely in your browser using JavaScript and WebAssembly.
• We do not have user accounts. We do not collect your name, email, or any personally identifiable information directly.
• The site shows ads via Google AdSense. AdSense uses cookies and may collect anonymized data for ad targeting and measurement.
• You are in control of those cookies through your browser settings or the consent banner where required.

Your files

Every tool on this site reads your files via the standard browser File API and processes them locally. Specifically:

• The file is decoded into a Blob or ArrayBuffer inside your browser tab.
• JavaScript libraries (pdf.js, pdf-lib, fontkit, jszip, marked, etc., loaded from a CDN) operate on the bytes in browser memory.
• The output, where applicable, is a Blob that your browser saves locally as a download.
• No fetch, XMLHttpRequest, or WebSocket request from this site sends your file content to any server.

You can verify this by opening your browser's Network panel and watching the activity while you use a tool: you will see no upload of your file's contents.

Cookies and local storage

The site itself sets a small number of localStorage keys to remember your preferences:

• toolbox-theme: tracks light or dark mode preference.
• tlbx-state-v1: tracks your visit streak and recently used tools (visible only to you, used to power the "Pick up where you left off" rail).
• pdfsign-library-v1: locally stored signature library for the PDF Sign tool. Only stored if you tick "Save to my library".

You can clear all of these by clearing site data in your browser settings.

Third-party cookies are set by Google AdSense and Google Fonts when their assets load. These are standard tracking and personalization cookies that you can opt out of via your browser, AdChoices, or your local privacy framework.

Advertising

This site uses Google AdSense to show ads. Google may use a cookie called DSID (or others) to personalize ads you see. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and other sites on the Internet.

You can opt out of personalized advertising by visiting Google Ads Settings, or for non-Google ads, the AboutAds.info opt-out page.

Analytics

This site does not run a third-party analytics tool. Standard Google Search Console and Blogger's built-in stats may report aggregated traffic data (page views, country, referrer) to the site owner without identifying individual users.

EU users (GDPR)

If you are in the European Economic Area, you have the right to access, correct, or delete personal data. Since the site does not collect personal data (no accounts, no submissions stored on a server), there is no profile to correct or delete on our side. For ad-related data, contact Google through the link above.

California users (CCPA)

You have the right to opt out of the "sale" of personal information. The site does not sell personal information. Ad cookies set by Google AdSense are subject to Google's controls; opt out via the link above.

Children

The site is not directed at children under 13. We do not knowingly collect personal data from children.

Changes

This Privacy Policy may be updated from time to time. The "Last updated" date at the top reflects the latest version. Continued use of the site after changes means you accept the updated policy.
