Privacy Policy

Last updated: May 2026

Overview

Knidos ("we", "our", "us") is a social bookmarking platform. This policy explains what data we collect, how we use it, and your rights. We do not sell or share your personal data with third parties for advertising purposes.

Data we collect

  • Account information — name, username, and email address when you register.
  • Profile information — optional bio you add to your profile.
  • Saved links — URLs you save publicly, including metadata (title, description, thumbnail) fetched from the linked page.
  • Bookmarks — URLs you save privately. These are never shown publicly.
  • Comments — text you write on saved links.
  • Follows — accounts you choose to follow.

What is public

The following are visible to anyone, including logged-out visitors:

  • Your username, name, and bio
  • Your public saves and the links they point to
  • Your comments

Private bookmarks, your email address, and your follow list are never publicly visible.

How we use your data

  • To operate the platform and provide the service
  • To display your profile and saved links to other users
  • To power the discovery feed based on what users save
  • To send transactional emails (e.g. password reset) via our authentication provider

We do not use your data for advertising, profiling, or any purpose unrelated to operating Knidos.

Chrome extension

The Knidos browser extension stores your authentication tokens (access token and refresh token) locally on your device using chrome.storage.local. This data never leaves your device except to communicate with Knidos servers for authentication. No browsing history is collected or transmitted.

Third-party services

  • Supabase — we use Supabase for authentication and database storage. Your data is stored on Supabase-managed infrastructure.
  • Vercel — the platform is hosted on Vercel. Vercel may process request metadata (e.g. IP address) as part of serving the application.

Data retention & deletion

Your data is retained for as long as your account is active. To delete your account and all associated data, contact us at the email below. We will process deletion requests within 30 days.

Cookies

We use a single session cookie to keep you logged in. We do not use tracking or advertising cookies.
