Social sharing features

This website includes share buttons for WhatsApp, X (formerly Twitter), LinkedIn, and Facebook. These are implemented as simple outbound links that open in a new window — they do not load any external scripts, iframes, or tracking pixels on this website, and therefore do not set any cookies. Cookies may only be set by these platforms if you choose to click through and interact with their services.

4. Infrastructure cookies

Depending on how you access this website, additional cookies may be set by infrastructure services outside of our direct control:

Cookie NamePurposeDurationSet By
__cf_bmBot management — used to identify and distinguish between humans and automated bots. This is classified as a strictly necessary cookie.30 minutesCloudflare (if applicable)
cf_clearanceSet after a user successfully completes a Cloudflare security challenge, so they are not challenged again for a period.30 minutesCloudflare (if applicable)

These cookies are set at the infrastructure level by Cloudflare and may not appear for all visitors. They are classified as strictly necessary security cookies and do not track personal information.

5. What we do NOT use cookies for

For full transparency, Excel Merge does not use cookies or similar technologies for:

  • User login or account systems (the website has no user accounts).
  • Payment processing (no payment gateways are integrated).
  • Remarketing or retargeting across other websites.
  • Social media tracking pixels or embedded social widgets.
  • Any form of fingerprinting or cross-site tracking beyond what is described above.

6. About local storage

Local storage is a browser feature that stores data on your device. Unlike cookies, local storage data is not sent to the server with each request, and it persists until you manually clear your browser data.

All local storage keys used by Excel Merge (listed in Section 3 under 'Preference storage') store only functional user preferences such as templates and theme settings. No personal or identifying information is stored in local storage.

7. How you can control cookies

Most web browsers allow you to control or disable cookies through browser settings. You can usually delete existing cookies, block future cookies, or set alerts when cookies are being placed. Here are links to cookie management instructions for common browsers:

  • Google Chrome
  • Mozilla Firefox
  • Microsoft Edge
  • Safari
  • Opera
  • Android browsers

Please note that disabling essential cookies may affect how the website functions. Disabling third-party cookies will prevent Google Analytics and Google AdSense from functioning, but the core website features will continue to work normally.

You can also opt out of specific services:

  • Google Analytics: Install the Google Analytics Opt-out Browser Add-on (https://tools.google.com/dlpage/gaoptout).
