Privacy Policy
This page explains the information SheetsFlow collects, why it is used and the choices available to you.
Information you provide
If you register an account, we process your email and password-derived authentication data. Newsletter signup records your email, language, chosen topics, separate article-update and marketing preferences, confirmation and unsubscribe state. We may process the information you send to our contact address.
Service and security data
We use session identifiers, authentication records and limited request information to run the website, prevent spam and investigate misuse. Administrative sessions are maintained with HttpOnly cookies. Optional third-party anti-bot verification may process request details under its own privacy terms when configured.
Why we process information
We use information to provide accounts and saved learning progress, deliver email you expressly requested, answer inquiries, maintain service security and improve educational content. Signing up for a website account does not automatically subscribe you to marketing.
Email and your choices
Newsletter signup uses email confirmation before activation. Lesson updates and marketing are separate, optional choices. Every newsletter includes an unsubscribe method; you may contact us to request access, correction or deletion.
Service providers and advertising
Hosting, database, media storage and email delivery providers may process information needed to operate the service. If advertising or analytics technologies are enabled, this notice and any required consent controls must be updated to describe the actual providers, cookies and choices before they operate. AdSense approval or advertising activation is not implied by this page.
Retention and security
We keep information as needed to deliver the service, honor unsubscribe choices, investigate abuse and satisfy applicable obligations. Retention needs may vary by record type. We use access controls, protected sessions and technical safeguards; no online service can guarantee absolute security.
Your requests
Email [email protected] from the address concerned to request access, correction, deletion or information about your subscription. We may verify your request before changing account data.
