Where everything actually is
| What | Where it lives | Who can see it | How long |
|---|---|---|---|
| Theme preference (light or dark) | Your browser's local storage | Only you, on that device | Until you clear your browser's site data |
| Language preference | Your browser's local storage | Only you, on that device | Until you clear your browser's site data |
| Sign-in session | Your browser, issued by Supabase | You, and Supabase as our authentication provider | Until you sign out, or the session expires |
| Your email address or account identity, if you sign in | Supabase | You, and NEURAX, to know who's signed in | As long as your account exists |
| A password, if you sign in with one | Supabase, as a salted hash | Nobody: it is never stored or shown in plain text | As long as your account exists |
| A demo or contact request: name, work email, company, role, team size, plan, topics and message | Sent from your browser to a Supabase Edge Function, then through Resend to contact@neuraxs.dev. No copy in a database | You, whoever reads that inbox, and the services that carry it (Supabase, Resend) | Until we delete the email, which we do when you ask. Resend’s delivery records follow Resend’s own retention |
| A feedback message: kind, message, optional rating, name and email | Sent from your browser to a Supabase Edge Function, which saves it in a private Supabase table and emails a copy through Resend to contact@neuraxs.dev. Never published | You, our team, and the services that carry it (Supabase, Resend) | Until we delete it, which we do when you ask or when you delete your account (if you sent it with that email). Resend’s delivery records follow Resend’s own retention |
| An anonymous request counter for the demo and feedback forms | Supabase: a salted hash of your IP address and a count, never the address | Only the form functions, to refuse a flood of requests | Cleared a day after its last use |
| Everything you design, analyse or train in the desktop application | Your own machine, only | You | Entirely up to you: see Security |
| Standard web request logs (IP address, page requested) | Cloudflare, as our host | Cloudflare's own infrastructure | Governed by Cloudflare, not something we separately store |
What’s deliberately not on this list
Analytics, advertising cookies, tracking pixels and third-party font requests: none of them run on this site, so none of them appear above. If any of that changes (for instance, once paid plans have a real, automated checkout instead of the contact form described in the Terms of Service) this table will grow a row that says so specifically, not a general clause that papers over it.
Removing what’s yours
Your theme and language preferences and your session are removed the moment you clear your browser’s site data for neuraxs.dev. For anything held in Supabase (your account, if you have one), or to ask what we hold about you, contact contact@neuraxs.dev.
