BeakerWise privacy policy

Last updated: 1 November 2026

This policy explains what happens to information in BeakerWise: The Real Science Lab ("the app") on a Meta Quest headset. The developer is dav3studios. The publisher is David Lee ("we", "us"). We wrote it for parents, carers and teachers. A short version for young people is at the end.

The short answer

This app does not collect or send any personal information. It has no accounts, no chat, no advertising, no analytics and no in-app purchases. Our own code makes no network requests. Explorers are pictures only: no names are asked for.

The app stores no personal data on any server. While it runs, it uses two items from your Meta account, on the headset only: the account's user ID and its age group. "Information from your Meta account" below says what they are, why the app gets them and what happens to them.

What the app keeps on the headset

One save file holds every explorer on this headset, with a backup copy of the save before it. For each explorer it keeps the picture and its colour, the reading depth, the explorer's own settings, the logbook, quiz and check answers, experiment results, badges, mission progress and the experiments visited. It also holds times: when each explorer was added and last played, and when each logbook entry, badge and visit happened. A second small file holds the grown-up settings for the whole headset: the time limit and how it counts, and the break reminder time. For the time limit it also keeps the time played, any extra time, the date and the last time the app was in use. The tablet's Photo button saves a picture and a small copy of it. Photos show the virtual lab only, never the real room. The album keeps the newest 60 photos of all explorers. All of this stays on the headset.

In more detail, for each explorer the save file keeps:

• the picture and its colour, and the reading depth (Quick Look, Explorer, Scientist or Expert)
• the explorer's own settings:
• comfort: how you turn and move, the comfort vignette, sitting or standing, and which hand holds the pointer
• sound: subtitles, the spoken narration, and the music, effects and voice volumes
• text: the text size, and whether buttons are read aloud
• how the tablet is held, in the hand or floating
• whether to use the real table (mixed reality)
• the logbook: experiments done, check answers and photos, each with its time. With a check answer the logbook also keeps the first answer picked, the number of tries, the reading depth, the title of the experiment or mission, and the curriculum statements that the question is about
• the experiment results: how many times each experiment was run, whether it was finished, and its best results
• the last 60 check answers: which question, where it was asked (the experiment, or the mission and its step), whether it was right, whether it was right first time, and when
• the badges, the mission that the explorer follows and the mission progress, and the experiments visited
• times: when the explorer was added and last played, and when each logbook entry, badge and visit happened

The grown-ups file keeps, for the whole headset: the time limit and how it counts (with any rest time), the break reminder time, and any journey switches. For the time limit it also keeps the time played, any extra time, the date and the last time the app was in use. BeakerWise has no journeys yet, so it has no journey switches.

The headset also keeps the app's prepared graphics data (a pipeline cache), so that the app starts faster next time. It holds nothing about you.

Your room and the bench

To place the bench, the app can ask to use your room's spatial data (where your table is). The app uses it on this headset only. It does not keep a map of your room. It keeps one thing: where you put the bench, so that the bench comes back to the same table next time. It saves this in a small file and as a spatial anchor (a saved position) on this headset, also when you place the bench by hand. Nothing is uploaded.

No camera

The app never asks for the headset cameras. The real room you see is shown by the headset, not by the app.

It never asks for the microphone either.

Deleting it

On the grown-ups page, "Reset progress" deletes the progress and the photos of the explorer who is playing. "Explorers" removes an explorer with their progress and photos. "Photos" deletes the photos of the explorer who is playing. Each of these writes the save file again at once, so the backup copy keeps no old data. "Room placement" has "Forget the room placement": it deletes the bench placement file and the saved spatial anchor. "Place the bench again" on the bench menu erases the old anchor and saves the new place. The grown-up settings stay until a grown-up changes them. Uninstalling the app deletes its files on the headset, photos included. The spatial anchor is saved by the headset's own system software, so uninstalling may not delete it. To be sure that it is deleted, use "Forget the room placement" before you uninstall.

We have no copy of any of it anywhere else.

Internet

The app's Android settings ask for the internet permission. The app keeps it for Meta's store checks only (see "What Meta does"). Meta says that the ownership check does not need an internet connection. Meta asks apps to make the age group check when the headset is online. Our own code never uses it, and nothing from the app itself is sent anywhere.

What Meta does

In the store version, the app asks the Meta system software whether this headset account owns the app, and which age group the account is in. The app reads the answers on the headset only. It does not store them or send them anywhere. Hand tracking, if it is on, is used on the headset to show your hands and is not recorded. The headset, the Meta account, the room scan and purchases are covered by Meta's own privacy policy.

"Information from your Meta account" below says more about both checks.

Meta's privacy policies are at https://www.meta.com/legal/privacy-policy/ and https://www.meta.com/legal/quest/privacy-policy/.

Information from your Meta account

The app asks Meta for two items about the Meta account that is signed in on the headset: the account's user ID and its age group. The app uses them only to run the app and to follow Meta's rules. Both stay on the headset. We never receive them.

The Meta Platform SDK handles both items. It is Meta's software library inside the app, and it works with the Meta system software on the headset. That system software may contact Meta to answer. Meta's own privacy policy covers that part.

Your user ID

• What it is: The user ID is Meta's identifier for the Meta account: a number that Meta gives to each account. It is not your name, your email address or your age.
• Why the app uses it: To run the app for the person who owns it. When the app starts, the Meta Platform SDK uses the account's user ID to check that the account owns the app. This is the entitlement check. It makes sure that only the owner of the app can use it. If the check fails, the app stops and shows a message with "Try again" and "Quit". The Meta Platform SDK also uses the account to ask for its age group.
• Where it is processed: On the headset only, inside the Meta Platform SDK, which uses it for the check. The app's own code does not copy it or keep it.
• How long it is kept: The app does not store it. Nothing of it is left after the app closes.
• Who receives it: We never receive it. The app never sends it to us or to anyone else. It is never used for advertising, analytics or profiling. It is never shared. To answer the check, the Meta system software on the headset may contact Meta. Meta's own privacy policy covers that part.
• How to delete it: There is nothing to delete, because the app keeps nothing of it. Uninstalling the app removes everything that the app keeps on the headset.

Your age group

• What it is: The age group is the group that Meta holds for the account, such as child, teen or adult. It is not your date of birth or your exact age.
• Why the app uses it: To follow Meta's rules and the law on children's data. The app is for mixed ages: for children from 10, and for teenagers and adults. Meta's rules for apps for mixed ages ask each app to check the age group of the account. These rules help apps follow the law on children's data. The app makes this check after the entitlement check, to follow these rules. The app is made to suit every age group that can use it. It has no chat, no online play, no advertising and no purchases for anyone.
• Where it is processed: On the headset only. The app keeps the answer in the headset's memory while it runs.
• How long it is kept: Only while the app runs. The app does not save it to a file. It is gone when the app closes.
• Who receives it: We never receive it. The app never sends it to us or to anyone else. It is never used for advertising, analytics or profiling. It is never shared. To answer the age group check, the Meta system software on the headset may contact Meta. Meta's own privacy policy covers that part.
• How to delete it: There is nothing to delete, because the app keeps nothing of it after it closes. Uninstalling the app removes everything that the app keeps on the headset.

Children

The app is made for ages 10 and over, their families and teachers. It asks for no names. It has no accounts, no chat, no advertising, no analytics and no in-app purchases, and its own code sends nothing from the headset. Nobody can contact a child through the app. The grown-ups page is behind a short check: a number written in words, then a three-second hold. It is not a lock. There a grown-up can set break reminders and a time limit.

Meta says: "Children's use of Meta Quest should always be supervised by an adult to reduce likelihood of injury or property damage."

Changes to this policy

If we change this policy, we change the date at the top and publish the new version at https://dhl84.github.io/beakerwise/privacy.html. We will not add any data collection without first changing this policy, the app's store listing and Meta's Data Use Checkup.

For young people

• The app does not ask for your name. It does not know who you are or where you live.
• Your experiments, results, badges and photos stay on the headset.
• When the app starts, it checks with Meta that your account owns the app, and which age group your account is in. This stays on the headset. The app forgets it when it closes.
• Nobody can talk to you in the app, and there are no adverts.
• If you have a question, ask a grown-up to email us.
