What we collect, why, who handles it, and the rights you have. Last updated 1 October 2026.
We collect as little as we can. For an account that means your email address and a hashed password. We run no advertising or analytics trackers, and we never sell your data.
VantageVault is operated by Zyntex (“we”). For any privacy question or request, email privacy@vantagevault.dev.
We use only strictly necessary cookies: the sign-in cookies. They are marked HttpOnly and Secure, so scripts on a page cannot read them, and they are shared across *.vantagevault.dev so one login works across our services. They are removed when you log out. We set no analytics, advertising or tracking cookies.
We do not use your data for advertising or profiling, and we do not sell it.
Two providers process data on our behalf. Supabase hosts our database and authentication, and stores your account data. Cloudflare provides hosting, DNS, network security and the gateway that handles sign-in. Essential emails are sent through our authentication provider. We share data with no one else, except where the law requires it.
No system is perfectly secure. If a breach affects your data, we will tell you and the relevant authorities where the law requires it.
Client-side, zero-knowledge encryption is the design goal for VantageVault Storage. It does not apply to the account system on this site, and we will not describe a service as zero-knowledge until it is.
We keep account data while your account exists. You can delete your account yourself from the Account page, which removes the account and its profile data. Copies may remain in provider backups for a limited time before they are overwritten, and providers keep short-lived technical logs under their own policies.
You can ask us to give you a copy of your data, correct it, delete it, restrict or object to its use, or export it. If you are in the EU/EEA, the UK or Switzerland, these rights come from the GDPR, UK GDPR and Swiss data protection law, and you may also complain to your local supervisory authority. Email privacy@vantagevault.dev; we aim to reply within 30 days.
Our services are not intended for children under 16.
If we change this policy we will update this page and its date. For significant changes affecting how we use your data, we will also email account holders.
