There is no signup wall and no file upload to our servers.
- Do Page Utils tools upload what I paste?
- No. Keys, tokens, JSON, Base64 text, and rupee amounts stay in the browser tab. We do not write that material to our servers or to localStorage. Close the tab and it is gone. JWT Token Decrypt, JWT Token Generator, and Password Generator stay ad-light because they handle secrets.
- Which tool categories are live right now?
- Live hubs are Finance, Developer, SEO tools, File conversion, and Text Utilities. Each hub lists only tools that actually work. Empty stubs stay unpublished rather than linking to a 404. Every live tool has one canonical URL with a trailing slash.
- Is Page Utils SEBI-registered or investment advice?
- No. Finance pages are education only: they show how a deposit check or similar system works, not what to buy. Nothing here is a securities recommendation. Page Utils is not registered with SEBI as an investment adviser or research analyst.
- How do I contact Page Utils?
- The only contact is a DM to @CrazyCitizen01 on X (https://x.com/CrazyCitizen01). Use that for questions about the tools, privacy, a correction, or ads. There is no public email address or personal name listed on this site.
- Do I need an account to use Page Utils?
- No. There is no account, login, or signup step. Open a live tool and use it in your browser.
- Is Page Utils free to use?
- Yes. The live tools are free to use. Some pages may show ads, but there is no paid plan or signup wall.
- Does a finance schedule represent a specific product?
- No. A schedule is an educational illustration based on the values you enter, not a product offer or recommendation. Check current terms with the relevant provider before making a money decision; Page Utils is not SEBI-registered.
