Privacy Policy

Last updated: 10 September 2026

Neurosync (“we”, “the app”) is a study tool for students. This policy explains what information we handle and why.

What we collect

Account details — email, password (stored securely by Supabase Auth — we never see your raw password), optional username and display name.
Study data you create — flashcards, notes, to-dos, progress, cookie-jar rewards, and similar content stored in your browser and/or our database when you are signed in.
Usage events — optional activity events (for example, completing a timer session) if that feature is enabled in our backend.
Resource suggestions & reviews — if you submit or review study resources.

Where data is stored

Supabase — authentication and cloud tables (profiles, shared decks, resources, etc.).
Your device — much of your private study content is kept in browser localStorage so it stays on your account on that device.
Analytics (optional) — if you accept cookies/analytics, we may use a tool such as PostHog to understand site usage. You can refuse.

How we use information

To run the app, keep you signed in, sync study features, moderate community resources, and improve reliability. We do not sell your personal information.

Sharing

We use processors such as Supabase for auth and database hosting. Shared/community features only show what you choose to publish. Admins may review resource requests and reports.

Your choices

You can log out anytime.
You can clear site data in your browser to remove localStorage content on that device.
To delete your cloud account, contact the site operator with the email you used to sign up.
Cookie/analytics consent can be changed by clearing site data or using the consent controls if shown.

Children & schools

Neurosync is aimed at high-school students. If you are under the digital consent age in your region, ask a parent/guardian before creating an account. School emails may be visible to other signed-in users for friend features depending on database settings — use a username you are comfortable sharing.

Contact

Privacy, account, or site questions: use Contact on the Neurosync site (account menu, home page, or footer). That opens a form that reaches the site operator.
