Model Teaching Apps Privacy Notice
Effective: September 8, 2026Last updated: October 2, 2026
This notice covers every app at apps.modelteaching.com. It’s written for a parent, a teacher, or a school reviewer, not a lawyer, and every claim in it matches how the apps actually work.
The short version
- No accounts. Students never sign up or sign in.
- No cookies. We do not set a single one on this site.
- No advertising. We never show ads or sell anything to your child.
- Nothing a child types leaves their browser. Practice answers stay on the device.
- One button erases everything. Clear your data any time, right on this page.

What the apps are and who they're for
Our apps are free, browser-based practice tools for students in kindergarten through twelfth grade, built to use alongside a teacher’s instruction or with family at home. We also publish two planning tools built for teachers only, the Math CFU Lesson Builder and the Writing Prompt & Rubric Builder, with no student-facing side.
What your browser stores
We cannot see any of this: it is stored on your device only and is never uploaded. When you generate or download something, the text for that one request is sent to our servers (see What is sent to our servers). It stays in this browser until you clear it, and clearing it takes one click (see Your choices below).
| Item | What it holds | How long it lasts | How to clear it |
|---|---|---|---|
| Device identifier | A random ID stamped on anything you save, so we can group your saved items together. It is never sent to us. | Until you clear it | “Clear data for all apps,” below |
| Preferences | Your theme, sound, and “clear on close” choices for each app. | Until you clear it | Same |
| Saved builds and templates | Worksheets, quizzes, flashcard sets, lesson plans, or writing prompts and rubrics you have saved, plus any title or text you typed for them. In the two teacher tools this also includes the plan or build you are working on, autosaved so a refresh keeps it. | Until you clear it (each app caps how many it keeps: 30 of each kind in most apps, 50 in Geography) | Same |
| Active session | The practice set you are currently working through, and whether each answer was correct. | Until you close the browser tab | Closing the tab, or the button below |
| Analytics opt-out flag | Set to “true” only if you have turned analytics off in this browser. | Until you turn analytics back on | The Analytics section below. This one is never touched by the clear-data button, on purpose. |
Some apps store a little more of the same kind: progress on individual questions, or a custom word list a teacher typed in, for example. It always follows this same pattern: saved to your device only, never uploaded, and included when you use Clear data for all apps below.
What we receive when you visit
Like every website, when your browser connects to ours, we automatically receive your IP address and browser type. We use it only to serve the site, count visits, and stop abuse. Specifically:
- Analyzing how the service functions
- Network communications
- Security and rate limiting
- Legal compliance
Here is how we make sure it is never used for anything else: we show no advertising and use no ad networks, we do not build profiles of visitors, we do not track anyone across other websites, we do not turn this into a user identifier, our content security policy technically blocks connections to any other destination, and we require a written agreement with every company we work with.
Analytics
Fathom Analytics is the only analytics tool we use. It sets no cookies. It reports at the country level, never the city. Any IP address it briefly sees is discarded within 24 hours.
We removed Google Analytics and Vercel Web Analytics on September 8, 2026: Google Analytics needed a two-year tracking cookie to produce useful reports, and Vercel Web Analytics recorded your city and had no way to delete that data.
Turn analytics off in this browser
Analytics are on for this browser
We count visits with Fathom, a cookieless analytics tool that never learns who you are.
Turning this off stops us from counting this browser’s visits entirely. You can turn it back on any time.
What is sent to our servers
A few specific actions send us information, and only for as long as it takes to complete that action:
- When a teacher generates a worksheet, we receive the settings they chose, plus any title or instructions they typed.
- In the Math CFU Lesson Builder, we receive the lesson text a teacher types in.
- In the Writing Prompt & Rubric Builder, we receive what a teacher enters (the writing idea, any topic or text title, and the checklist, prompt, and rubric wording) and the choices made. To make a download, we also receive the whole build on screen, including its printout title and any rubric text the teacher wrote.
- When someone sends us feedback, we receive their message.
Our servers use each of these once and then discard it, except a feedback message, which we keep as described in How long we keep things. Teachers and parents: please do not type a student’s name or any other personal information into any of these fields.
Who else receives anything
A handful of companies help us run these apps. Here is everything each one receives:
| Company | What they get | Why | How long |
|---|---|---|---|
| Fathom Analytics | Page path, browser type, operating system, device type, country, and the time of your visit. Your IP address only briefly. | Count visits and see which features get used | Personal details are gone within 24 hours. Usage totals are kept as long as we use Fathom. |
| Vercel (our host) | Your IP address, browser type, and the page you requested | Serve the site and keep it secure | Kept 1 day |
| Anthropic | Math CFU Lesson Builder: the lesson text a teacher types. Writing Prompt & Rubric Builder: the writing idea, the grade and choices made, any topic typed for idea suggestions, the title of a text, any role, audience, format, or topic typed for creative writing, and the checklist, prompt, and rubric wording, including the rubric’s row names and level labels. Never the printout title or rubric descriptions the teacher wrote. | Write the lesson content, writing prompt, rubric, or idea suggestions the teacher asked for, and check that the result suits a classroom | Deleted within 30 days (longer only if flagged for a safety review) |
| Resend | The feedback message, which app it is about, and the page it came from | Deliver the message to our team | Kept until we have resolved it, at most 12 months |
We require a data-processing agreement with every company that receives anything through our apps. That agreement limits what they can do with it.
Nobody else receives anything. Our content security policy blocks the browser from connecting to any destination beyond our own servers and Fathom, so even if we made a mistake in our code, there is nowhere else for a visitor’s browser to send data.
How long we keep things
This is our complete data-retention schedule. Nothing on it is kept forever.
| Category | Purpose | Business need | Where | Retained | Deleted by |
|---|---|---|---|---|---|
| Visitor IP address and user agent | Serve the site and protect it from abuse | Network communications and security | Host request logs; in-memory rate-limit hashes | Logs at most 1 day. In-memory hashes expire after 1 hour (24 hours for the teacher tools' daily caps) and disappear whenever a server instance restarts. Never written to disk. | Automatic |
| Analytics visitor hash | Count unique visits | Analyze the functioning of the service | Fathom | At most 24 hours. The salt rotates daily. Raw IP address at most 24 hours in Fathom's access log. | Automatic |
| Aggregate usage statistics (no personal data) | Product decisions | Understand which apps and features are used | Fathom | Life of the account | Deleting the Fathom site |
| Browser-stored settings, saved items, session data | Provide the features you asked for | Provide the features you asked for | Your own device only | Until you clear it. Session data until the tab closes. | You, in one click |
| Teacher lesson and writing-assignment text sent to Anthropic | Generate lesson content, writing prompts, and rubrics | Generate lesson content, writing prompts, and rubrics | Anthropic | Deleted within 30 days. If trust-and-safety systems flag it, the content is kept up to 2 years and its safety scores up to 7 years. | Automatic |
| Feedback messages | Fix bugs and consider requests | Fix bugs and consider requests | Our team's mailbox, delivered by Resend | Until resolved, at most 12 months | Us |
| PDF and Word file requests | Make a worksheet, lesson plan, or printout | Make a worksheet, lesson plan, or printout | Nowhere. Processed in memory and discarded. | Seconds | Automatic |
| Personal information from children beyond the above | Not applicable | None collected | Not applicable | Not applicable | Not applicable |
Children's privacy
Our apps are meant for children, including children under 13. We do not collect personal information from your child. We never ask for a name, an email address, a login, a photo, or a recording, and there is no account to create.
The only information our servers ever receive automatically from any visitor’s browser is described above, in What we receive when you visit. It is technical, it is used only to run and protect the site, and it is never used to identify, contact, or advertise to your child. Because of that, there is nothing here that requires your permission as a parent.
If you would like to erase whatever your child’s device has saved, like a preference or a saved quiz, use the button in Your choices below. If you have any question about your child’s privacy, email us at apond@modelteaching.com.
Schools
We hold no education records. Students have no accounts and no data on our servers, so there is nothing for a school to review, correct, or delete on our systems. Teachers: please do not enter any student information anywhere in these apps.
For a one-page summary written for a school technology or privacy reviewer, see our Student Privacy page.
Do Not Track
We do not track you across other websites, and we do not allow anyone else to, either. There is genuinely nothing here for a Do Not Track signal to switch off. We honor it anyway in our analytics: Fathom is configured to respect your browser’s Do Not Track setting.
Your choices
Clear your data. This removes everything every Model Teaching app has saved in this browser.
This only affects this browser, on this device. Anything saved just for the current tab already clears when you close that tab; this clears everything else too, in every tab.
Turn off analytics. See Analytics above for the on/off switch for this browser.
Use your browser’s own controls. You can clear cookies and site data for apps.modelteaching.com any time from your browser’s settings, or use a private or incognito window so nothing is saved after you close it.
How we announce changes
If we make a material change to this notice, we will update the “last updated” date at the top of this page and describe what changed. Because our apps do not collect email addresses or accounts, we have no way to notify you directly, so please check back if you would like to know what has changed.
Most recent change, October 2, 2026: we added our second teacher tool, the Writing Prompt & Rubric Builder, to what the apps are, what your browser stores, what is sent to our servers, who else receives anything, and how long we keep things. We also clarified that the teacher tools autosave your work in progress on your device, how many saved items each app keeps, that feedback messages are kept until resolved, and how long Anthropic keeps flagged content and its safety scores.
