Privacy Policy

Last updated: October 27, 2026

BioStack (links.elimbi.com) is a small independent project run by William Mbotta, an individual developer based in France. This page explains, in plain words, what data we keep and why.

What we store

• Account: your username and a securely hashed password (bcrypt). We never see or store your password in clear text.
• Email and name: if you sign in with Google, we receive your Google account email address, your name and a Google account ID. We use them only to sign you in and to contact you about your account if needed.
• Your page: the display name, bio, theme and links you add. This content is public on your /username page.
• Counters: the number of views of your page and clicks on each link. These are simple totals, not tied to any visitor.
• Billing: if you buy Pro, payment is handled by Stripe. Your card details go to Stripe and never touch our server. We keep only your subscription status, linked to your username.

Cookies and analytics

We use one cookie to keep you logged in, plus a short-lived cookie during Google sign-in to protect against forged requests. For site statistics we use a self-hosted Umami instance, which is cookie-less and does not collect personal data or track you across sites. No ads, no third-party trackers.

Who we share data with

We do not sell your data. We only rely on: Stripe (payments), Google (if you choose Google sign-in), and our hosting provider in Europe that runs the server.

How long we keep it

We keep your data as long as your account exists. Ask us and we will delete your account and page.

Your rights

Under the GDPR you can access, correct, export or delete your data, and object to its use. Email williamelimbi@gmail.com and we will reply within a few days. You can also complain to the CNIL (cnil.fr).
