The short version
- You can use Experivio without an account. Then your work stays in this browser on this device.
- If this site offers Google sign-in and you use it, a copy of your Experivio work is saved in your account so you can open it on other devices.
- When you use an AI feature, the text needed for that request is sent to Anthropic, the company that makes the Claude AI model, to create the answer.
- Experivio has no ads and no analytics or tracking tools, and it doesn’t use cookies.
- Accounts are only for students who are 13 or older. Everyone can use every tool without an account.
- You can download everything, and you can delete your saved work, and your account if you have one, at any time.
What is saved, and where
| What | Where | When |
|---|---|---|
| Your projects, data tables, notes, Discover choices, coach chats, practice answers and display settings | This browser’s storage on your device | Always (this is how Experivio saves) |
| The same project data, the time of each change, and a random label for the device that made it | Your Experivio account, stored in Google Cloud Firestore | Only if you sign in |
| Your name, email address and Google account ID, and a sign-in token kept in your browser | Google Firebase Authentication | Only if you sign in with Google |
| A note that you said you are 13 or older (not your birth date) | Your Experivio account | Once, when your account is created |
| Your birth month and year | Not saved anywhere | Only used on the sign-in page to decide whether an account can be made |
Who can see it
Work saved only in your browser stays on your device. If you sign in, only your account can read and change its saved work: the database rules block everyone else. The site owner, as the administrator of the Firebase project, can technically access stored account data and will only do so to fix a problem or if the law requires it. Experivio does not sell or share your data, and does not show ads.
AI features
When you use an AI feature (for example the Science Coach, idea suggestions, the Experiment Designer, data explanations, or judge questions and feedback), Experivio’s server sends the text needed for that request to Anthropic’s API to create the answer. Depending on the feature, that can include what you typed, the details of your current project (such as your research question, variables and data summary), your practice answers, and the grade, explanation level and favorite science fields you chose.
Experivio’s server passes the request through and returns the answer; it doesn’t store the text. Anthropic processes the request under its own terms and privacy policy: anthropic.com/legal/privacy. Don’t type personal details such as your full name, address or phone number into AI features.
In the Coach, you can turn off “Share this project with the mentor” to ask general questions without sending your project details.
Hosting and security
Experivio is hosted by Netlify, which processes standard technical information such as IP addresses to deliver the website. Experivio’s server keeps your IP address only in its temporary memory, to stop too many AI requests in a short time. It isn’t written to a database or to Experivio’s logs.
How long it’s kept
- On your device: until you delete it, clear your browser’s data, or choose “remove from this device” when signing out.
- In your account: until you delete it. Experivio doesn’t delete accounts automatically. Deleting a project removes it from your account the next time it syncs. Deleting your account removes all of its Experivio data from the database right away.
- Backups by Google: Google may keep deleted data in its own backups for a limited time, as described in its terms for Firebase and Google Cloud: firebase.google.com/support/privacy.
Download or delete your data
- Without an account: use Download backup in Experivio to save your projects as a file. To delete them, delete the projects in Experivio or clear this site’s data in your browser settings.
- With an account: choose your name in the account menu, then Download backup file, Download my account data (everything saved in your account), or Delete account (permanently deletes your account and all of its saved work; Google asks you to confirm first).
Contact
A contact form for privacy questions is coming soon. Until then, you can download or delete all of your saved work yourself, as described above.
