Privacy Policy
Last updated 2026-10-16
The short version
- This game is made for kids. It works with no account, no name and no email address.
- Your progress stays on your device. We cannot see it.
- Only if an adult says yes, the game sends anonymous play info (like which questions are tricky). It never says who you are.
- We do not show ads, sell anything, or share this info with anyone else.
- An adult can turn the sharing off at any time, and delete everything saved on the device, in Settings.
Who we are
Aurex Labs LLC runs Build the Periodic Table ("we", "us"). You can reach us here:

What stays on your device
Your player nickname (picked from a list), favorite element, elements collected, badges, scores, how many questions you got right and wrong in each topic (for the adult Progress report in Settings), which questions you were shown recently (so the next round picks fresh ones), settings and any study sets you make are saved only on this device. We never receive them.
To remove them, an adult can open Settings, tap Saved Data, and delete one player or everything. Deleting the app removes them too.
Anonymous play info (only with an adult's OK)
The first time the game opens, it asks an adult whether it may send anonymous play info. If the answer is no (the default), nothing is sent. If the answer is yes, the game sends short messages like these: which screen was opened; when the app was opened or closed; which element block was placed, and when a block fell off the stack; whether an answer was right or wrong, with its element, topic and level; how a round started and ended, why, how long it took and what share of the answers were right; which badges were earned; whether the first-round tips were finished or skipped; and the version of the app.
Each message carries a random number that the game makes up when it opens (and makes again after the app has been in the background for 30 minutes). That number is not saved on your device and is not linked to your name, your device, or anything else about you.
We do not collect names, email addresses, photos, voice, location, contacts, or any advertising or device identifier.
Why we use it
Only to run and improve the game: to fix bugs, to see which questions are too hard or too easy, and to see which screens are confusing. These are our "internal operations".
We do not use it to contact anyone, to build a profile of any child, to show ads, or for anything else, and we do not combine it with other information.
Who handles it
The messages are stored for us by Supabase, a cloud database company that acts as our service provider. We do not sell this information or share it with anyone else.
Like most internet services, Supabase's servers note the internet address (IP address) of each request in their security logs for a short time, about a day. We do not receive, use or keep those addresses ourselves.
How long we keep it
Play info is deleted automatically after 90 days. Things saved on your device stay there until you delete them.
Our website and the teacher pilot
Our website, buildtheperiodictable.com, has no ads, no tracking and no cookies of its own. It is hosted by Netlify, whose servers note the internet address of each visit in their logs, as most websites do.
Teachers and other adults can sign up for our teacher pilot with a form on the website. We receive what they type there (such as name, email address, school and grades taught) through Netlify, and use it only to contact them about the pilot and the teacher plan. We do not sell it or share it with anyone else. The form is for adults only. To have a sign-up deleted, email us.
An adult's choices
- Change your mind any time: in Settings, switch "Share play info" off. Turning it on needs the adult check; turning it off does not.
- Delete what is saved on the device: Settings, then Saved Data.
- Because play info has no name or lasting ID, we cannot find one child's messages. Turning sharing off stops any more from being sent, and old messages are deleted on their own after the time above.
- Questions, or want to ask us to review or delete something? Email us at the address above.
Children
This game is designed for children. We do not knowingly collect personal information such as a name, email address, phone number, address, photo, voice or exact location from children. There are no accounts, no chat, no ads and no social features. The one purchase (unlocking the full game, a one-time purchase through Apple) and the only ways out of the app (sending us feedback by email, and sharing your element count with the phone's share sheet) are behind an adult check. Apple handles the payment; we never see payment details.
If you think we received personal information from a child, email us and we will delete it.
Keeping it safe
Play info travels over an encrypted connection, and the database only accepts new messages from the app: the app cannot read anyone's messages back.
Changes
This policy was last updated on 2026-10-16. If we change how we handle information in a way that matters, we will tell adults in the app before the change starts.
