Privacy Policy
Last updated: September 8, 2026
This app follows the Model Teaching Apps Privacy Notice. This page covers only what is specific to Periodic Table Study.
What this app saves on your device
None of it is sent anywhere, with one exception: when you generate a study-sheet PDF (see below).
| Item | What it holds | How long it lasts |
|---|---|---|
| Device identifier | A random ID stamped on anything you save, so your saved items stay grouped. Never sent anywhere. | Until you clear it |
| Preferences | Your theme (light, dark, or system) and other display choices. | Until you clear it |
| Saved quiz and flashcard configurations | Build configurations you have saved. | Until you clear it |
| Saved study-sheet templates | Study-sheet configurations you have saved. | Until you clear it |
| Explorer quiz preferences | Your settings for the Explorer quiz mode. | Until you clear it |
| Analytics opt-out flag | Set only if you have turned analytics off in this browser. | Until you turn it back on |
What this app sends to our server
When you generate a study-sheet PDF, we receive the settings you chose and, if you typed them, a title (up to 160 characters) and instructions (up to 400 characters). We use this only to build the PDF and send it back. We do not store it or log it.
Please do not type a student’s name or any other personal information into the title or instructions.
Analytics
We use Fathom Analytics to count visits and see which features get used. Fathom sets no cookies, reports at the country level only, and briefly sees your IP address before discarding it within 24 hours. On September 8, 2026, we removed Google Analytics and Vercel Web Analytics from every Model Teaching app. Fathom is now the only analytics tool on this site. Read more, or turn analytics off in this browser, on the Model Teaching Apps Privacy Notice.
Children’s privacy
Periodic Table Study is made for children, including children under 13. We do not collect personal information from your child: no name, no email address, no login, no photo. The only automatic data is described above and in the Model Teaching Apps Privacy Notice.
Clearing your data
Open Settings in this app and use the Wipe All Saved Data button to remove everything this app has saved on your device. The Model Teaching Apps Privacy Notice also has a button that clears data for every Model Teaching app at once, including this one, because every app shares one browser origin.
