Privacy Policy

ToolKit is a collection of free online utilities that run entirely in your browser. We have designed it to collect as little about you as possible. This policy explains what does and does not happen with your data.

Last updated: 23 June 2026

1. Tools run locally — your content is not uploaded

Every tool on this site (JSON formatting, image compression, OCR, hashing, file viewing, and so on) processes your input locally in your browser. The text, images, audio, video and files you load are never uploaded to our servers — we do not operate an application server that receives them, and we cannot see them.

2. No account, no profile

There is no sign-up and no login. We do not ask for your name, email, or any personal information to use the tools, and we do not build a profile of you.

3. Local storage on your device

We may store small preferences (such as your chosen language) in your browser's local storage. This stays on your device, is not sent to us, and you can clear it at any time through your browser settings.

4. Cookies and third-party advertising

This site is supported by advertising. We use Google AdSense to display ads. Third-party vendors, including Google, use cookies and similar identifiers to serve ads based on your prior visits to this and other websites.

• Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.
• You can opt out of personalised advertising by visiting Google Ads Settings.
• You can learn how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites.
• For more choices about third-party advertising cookies, see aboutads.info/choices and youronlinechoices.com.

5. Other third-party services

The site is hosted on a content delivery network (Vercel), which may log standard request information such as IP address and user agent for security and reliability. Some in-browser tools download library or model files (for example OCR language data) from third-party CDNs the first time you use them; those requests are subject to the respective providers' policies.

6. Analytics

We do not run our own analytics or behavioural tracking on this site.

7. Children

This site is not directed to children under 13, and we do not knowingly collect personal information from them.

8. Changes to this policy

We may update this policy from time to time. Material changes will be reflected by the "last updated" date above.
