Privacy Policy

We respect visitor privacy and follow the policy below. Video / audio tools run entirely in the browser — files are not uploaded to any server.

Last updated: April 27, 2026

About file processing: Video and audio tools (compress, GIF, audio extract, volume normalize, etc.) run via ffmpeg.wasm directly in your browser. Uploaded files stay in your device's memory and are never sent to the operator or any third party.

1. Information collected

This site may collect the following information:

We do not collect personally identifiable information (name, address, phone number) except as you submit it via the contact form.

2. Cookies

This site may use cookies for analytics and ad delivery. Cookies are small text files stored in your browser and do not by themselves directly identify you.

You can disable cookies in your browser. You can keep using the site with cookies disabled, though some analytics or ad-related features may not function.

3. Analytics (Google Analytics 4)

This site uses Google Analytics 4 to analyze traffic. Data is sent to and stored on Google's servers, and used to improve the site. No personally identifiable information is included.

4. Advertising

To help cover hosting and operating costs, this site may use advertising services such as Google AdSense. Ad providers may use cookies to display ads tailored to your interests.

Ads may be inactive while AdSense approval is pending or while ad units are being set up. This policy applies regardless of whether ads are currently displayed.

5. Cookie consent

A cookie consent banner is shown at the bottom of the page on your first visit.

When analytics and advertising services are actually activated, we plan to layer in cookie-consent / Google Consent Mode controls in stages. Updates will be announced on this page along with any change in scope.

6. Affiliate programs

This site may participate in affiliate programs such as Amazon Associates. Articles that contain affiliate links will indicate so. A referral fee may be paid when a product is purchased via these links; product selection is editorial.

7. Contact form

The contact form is provided by Tally (tally.so). Submissions are stored on Tally's servers — see Tally's Privacy Policy.

Information you submit is used solely to answer your inquiry and inform editorial improvements; it is not shared with any third party.

8. Third-party disclosure

Personal information is not shared with third parties except as required by law.

9. File handling for video / audio tools

Video and audio tools on this site process files via ffmpeg.wasm directly in your browser. Output files exist only on your device — the operator cannot access them.

10. Disclaimer

Information is provided "as is" without warranty of completeness or currency. The operator is not liable for any damages arising from use of information on this site.

11. Changes to this policy

This policy may be updated. Significant changes will be reflected in the "Last updated" date and announced on the site.
