Privacy Policy

Last updated 2 November 2026

Tools by 313bits (tools.313bits.com) is a set of free calculators and converters. They are built so that what you type stays with you.

Your numbers, text and photos stay on your device

Every tool works inside your own browser. The dates, amounts, text, Wi-Fi details and photos you enter are never sent to us or stored on our server. The image compressor works on your phone — your picture is not uploaded.

What is remembered on your device

Some tools remember your last settings so you do not have to type them again — for example the gold rate you entered, the marla size you chose or the text in the word counter. These are kept in your browser (in localStorage) on your device only. Clearing your browser data removes them.

No account, no profile

There is nothing to sign up for. We do not ask for your name, email or phone number, we do not build a profile of you and we do not sell data about you.

Server logs

Our web server keeps standard logs — the page requested, the time, your browser type and your IP address — to keep the site working and secure. These are kept for a short time and are not used to identify you.

Advertising cookies (Google AdSense)

This site is free because of ads. We use Google AdSense, which may set cookies or read device identifiers to show ads and to measure them. Where it is required, Google’s consent message asks for your choice before personalised ads are shown, and you can change that choice at any time from the link in that message.

Ads appear below each tool’s result and on the home page, never between a tool’s boxes and its buttons. Ads are shown by Google and cannot see what you type into a tool.

Children

We do not knowingly collect personal information from anyone, children included, because we do not ask for any.

Your rights

Since we hold no account data about you, there is usually nothing for us to show or delete. If you believe we hold information about you, write to us and we will help.

Changes

If this policy changes, the new version appears on this page with a new date.
