Privacy Policy

Last updated: November 12, 2026

AIPreciseTools is built to need as little of your information as possible. This page lists exactly what stays on your device and what a few online features send.

What stays on your device

The calculators, converters and generators do their math in your browser. The numbers, dates and text you enter are not sent to us. Generated passwords are created with your browser's cryptographic random number generator and never transmitted.

Receipt photos never leave your device. The Smart Tip Calculator reads the text of a receipt inside your browser. The image is not uploaded.

Your saved tools, saved vehicles and recent tips are kept in your browser's local storage so they are there when you come back. They are not sent to us, and clearing your browser data removes them.

Images and videos you open in our media tools never leave your device. Resizing, converting, compressing and making GIFs all happen inside your browser.

Offline copies. To make the site work offline and load faster, your browser keeps copies of the pages and code you open (not anything you type or upload). Stream overlays you set up save their own timer and goal progress in the browser source that shows them.

Site statistics. We may use Cloudflare Web Analytics to count visits and see which pages are popular. It doesn't use cookies or track you across sites, and it doesn't collect what you type into a tool.

Online features, and what each one sends

• Vehicle lookup. The year, make and model you pick are sent to our server, which fetches official figures from the U.S. EPA's fueleconomy.gov. We do not store these requests.
• Approximate location. To suggest local tipping customs, the tip calculator asks our server for the country and state or region that your network connection appears to come from. It is used to pre-fill two menus, is never more precise than a region, and is not stored.
• Community tip averages. If you choose "Share my tip anonymously", we store only the type of place, the country, the state or region, the tip percentage and the date. No name, amount, receipt or IP address is stored with it.
• Trip routes. When you search for a place or a route in the fuel cost calculator, what you type and the places you pick are sent to our server, which asks OpenRouteService (run by HeiGIT in Germany) for matches and the driving distance. Your approximate area, rounded to about 50 km, is used to show nearby places first. We do not store these searches.
• Speed test. The Stream Settings Finder sends random test data to our server to measure your connection. Nothing about the result is stored.
• Floor plans are read on your device, like receipts, and are never uploaded.
• Password leak check. Your browser sends only the first 5 characters of a one-way SHA-1 code made from the password to Have I Been Pwned's Pwned Passwords service, and compares the reply on your device. The password itself is never sent to anyone.
• Helpful votes. When you press "Helpful", we add one to a counter for that calculator. Your browser remembers that you voted; we store only the count.
• Feedback. If you send a message with "Report a problem", we store the message, which calculator it's about, the date and, if you leave the box ticked, the link with the numbers on that page. No name, email or IP address is stored with it.
• Contact form. Messages sent from the contact page are stored with the date. If you add your email address so we can reply, it is stored with your message, used only to answer you, and deleted when the conversation is over. If you email us instead, we keep the email only as long as needed to reply.
• Embedded calculators. When another website embeds one of our calculators, it runs the same way as here and the host site can't read what you type into it.
• Connect Twitch (optional, for stream overlays). If you connect your Twitch account at /connect/twitch, Twitch gives our server an access token with the read permissions listed on that page (plus sending chat messages for the chat bot). We store the token encrypted, with your Twitch user ID and name, looked up by a hash of a random key that only your overlay links contain. Overlays use it to receive Twitch events directly from Twitch on your computer; we don't store your events or chat. Disconnecting deletes the token and revokes it at Twitch, and unused connections are deleted after 60 days.
• Giveaway wheel. For Twitch and Kick, your browser connects directly to their public chat services as an anonymous, read-only viewer. If you use Social Stream Ninja, your browser connects to its relay with the session ID you enter. For YouTube and Rumble, our server fetches the public chat (or, for Rumble, your Live Stream API data) on your behalf and passes the messages straight back; it does not store them, your Rumble API key, or anything else about the giveaway. Entries and past draws are kept on your device.
• AI tip advisor. If you press "Ask the AI advisor", the text read from your receipt and the details you entered are sent to our server and processed by an AI model run by Cloudflare (Workers AI) to produce a suggestion. We do not store that text. Do not use it for receipts with information you want to keep private.

To prevent abuse, the two features above count requests using a scrambled, one-way code that changes every day. It cannot be turned back into an IP address and is deleted within a few days.

Advertising and cookies

AIPreciseTools is free because it shows ads. The ads are served by Google AdSense. Google and its partners use cookies and similar technologies to show ads, limit how often you see the same ad, measure how ads perform and, if you allow it, choose ads based on your interests and your visits to this and other websites.

• Google's use of advertising cookies lets it and its partners serve ads based on your visits to this and other sites. See how Google uses information from sites that use its services.
• You can turn off personalized ads from Google in My Ad Center, and opt out of many other companies' personalized ads at aboutads.info or youronlinechoices.eu.
• Visitors in the European Economic Area, the UK and Switzerland are asked for consent through a consent message before personalized ads or advertising cookies are used, and can change their choice at any time from the "Privacy and cookie settings" link that message adds to the page.
• U.S. residents of states with privacy laws, such as California, can opt out of the "sale" or "sharing" of personal information for targeted advertising through the same settings, or by turning on Global Privacy Control in their browser.

Ad cookies are set by Google, not by AIPreciseTools, and we never pass anything you type into a calculator to advertisers.
