Privacy policy
Last updated 13 November 2026
This policy covers the Complexity Software website at complexitysoftware.app and the Complexity Stream app at stream.complexitysoftware.app (the “Stream app”). Complexity Software is operated by Paulo De Guzman, who is also the Data Protection Officer. Contact: contact@complexitysoftware.app.
The company website
The Complexity Software hub is a static site. It does not offer accounts, and it does not ask you for a name, email, or payment details. Our host, Cloudflare, may keep basic technical logs (such as IP address and user agent) for security and reliability.
Complexity Stream — what we collect
- Account details. Your email, display name, chosen avatar, and an optional birthday (used only to hide titles rated above your age).
- Sign-in. If you create a password, we store a salted password hash (PBKDF2). If you sign in with Google or Facebook, we receive your name, email, and an account identifier from that provider. We never receive your Google or Facebook password, and we never post anything on your behalf.
- Viewing data. My List, your watch progress per episode, and your settings, so they can sync across devices.
- Guests. A random cookie that counts free viewing minutes. No name or email is attached to it.
- Basic logs kept by our host (Cloudflare) for security and debugging.
What we don’t do
- We don’t sell your data, and we don’t share it with advertisers.
- We don’t host or download video. Episodes play in YouTube’s official player. That playback is covered by the YouTube Terms of Service and Google’s privacy policy, and may include YouTube ads.
Cookies
The Stream app uses two first-party cookies: sid keeps you signed in (30 days) and gid counts guest viewing time. A short-lived cookie protects Google and Facebook sign-in from forgery.
Your choices
- Download everything we hold about you: in the Stream app, go to Settings → Privacy & data → Download my data.
- Delete your account and all of its data: Settings → Privacy & data → Delete account, or see Delete your account.
- Clear your watch history at any time in Settings.
Retention
Account data is kept until you delete your account. Deleting it removes your profile, watch progress, My List, settings, and linked Google or Facebook IDs straight away.
Children
Complexity Stream is not directed at children under 13.
Changes
We will update this page and its date when anything changes.
