Data & Privacy Statement

SumRunner’s tools ask for the minimum they need to make a printable product — usually student names, sometimes a period or class label, and whatever you type into a tool (seat positions, rubric text, feedback selections, timer settings).

All of it is written to your browser’s own storage on your own computer — localStorage for most tools, and IndexedDB for graded writing, which needs more room than localStorage allows. Both are the same kind of thing: a storage area the browser keeps for this site, and nowhere else. It is per-browser and per-device: a roster typed in Chrome on your classroom desktop does not appear in Safari, on your laptop, or on any other teacher’s machine. Nobody — including the developer of this site — can see it.

No student information is transmitted, to anyone, ever.

Loading the site downloads the page and its fonts from the web host, exactly like opening any web page. After that, the tools run entirely inside your browser. PDFs are generated on your own machine. You can disconnect from the network after the page loads and every tool, including printing a full class set, still works.

SumRunner contains no analytics, no tracking pixels, no advertising, no third-party scripts, and no third-party fonts. It sets no cookies. The AI-writing reference tool includes citation hyperlinks to outside sources; those are ordinary links that go nowhere unless you click them.

The one thing outside your device is the web host, which serves the page files. Like any web server it records ordinary request information such as your IP address and which files were requested. That is the same footprint as visiting any website, and it never includes anything you typed into a tool.

Rules about student data generally exist because the information leaves your control and is kept by a vendor — which is what creates a new record someone else holds. That does not happen here. Because nothing is transmitted, SumRunner never receives, stores, or maintains student information, and no record is created outside your own device.

Functionally, typing a roster into SumRunner is equivalent to typing it into a spreadsheet on the same computer. The privacy considerations that apply are the ones that already apply to that spreadsheet.

This statement describes how the software works. It is not a district approval, and it does not replace one. If your district maintains an approved-tools list, treat that list as authoritative and check before using this site with real student information.

Being local is not the same as being risk-free. Three things are worth planning for:

• Shared computers. Data stays in the browser profile you used. On a shared or lab machine, the next person using that same profile could open the tool and see it. Clear your data before you walk away, or avoid shared machines for real rosters.
• What you print or export. A saved PDF or a printed name tent is student information on paper or on disk, and it is subject to the same handling rules as any other classroom document.
• There is no backup. Because nothing is stored on a server, clearing your browser data, using private browsing, switching devices, or a browser reset will permanently erase your work. Nobody can recover it for you. Use the export option in Documents if you need a copy you can keep.

Clearing your browser’s site data for this site removes all of it immediately and permanently. In most browsers that is Settings → Privacy → Clear browsing data → Cookies and other site data, or via the padlock icon in the address bar for this site specifically. Individual tools also offer their own clear actions.

You do not have to take any of this on faith, and you should not have to read the source code either. Two checks anyone can run in about a minute:

• Open your browser’s developer tools, switch to the Network tab, then build something with real names. No request carries the names, because no request is made.
• Load the site, turn off Wi-Fi, and keep working. Every tool continues to function and PDFs still generate — which is only possible because nothing is being sent anywhere.
