EXCEL EXERCISES · PRIVACY & ABOUT · VERSION 0.4.1
Your learning stays on your device.
Excel Exercises is an independent spreadsheet practice course. The beginner workbook includes 80 free tasks; Pro adds 92 online exercises. It is not affiliated with Microsoft or ExcelExercises.com.
Learning records
Results, practice dates, lesson position, and preferences are stored locally in this browser or extension. They are not uploaded to a Excel Exercises learner database. Progress backups contain learning records only; they do not include payment credentials. The website and installed extension have separate learning records.
Paid access and payment data
Purchases, purchase restoration, and subscription management use ExtensionPay and Stripe. Those providers process checkout information, including the purchase email and payment details, under their own policies. Excel Exercises does not receive card numbers. ExtensionPay stores a license credential and payment-status information in Chrome extension storage, using Chrome sync storage when available and local storage as a fallback. That provider record can include the purchase email, installation date, plan, and subscription status.
The installed extension sends its license credential over HTTPS to the Excel Exercises server, which verifies it with ExtensionPay before sending a protected lesson. The credential is not put into Excel Exercises page URLs or progress backups. Purchasing does not create a separate Excel Exercises password. Payment restoration uses ExtensionPay's email-based flow; progress restoration uses a separate local backup.
Hosting and requests
Cloudflare hosts the website and course API. Hosting and payment providers process normal connection information such as IP addresses, request times, and browser headers. The beginner workbook runs offline; Pro requires internet access for verification and lesson delivery. We have not added advertising, behavioral analytics, or access to personal spreadsheets or browsing history.
Extension permissions
The storage permission saves learning records and the payment provider's license information. Access to sheetreps.pages.dev allows the extension to fetch course metadata, verify access, and download authorized lessons. A locally packaged ExtensionPay script runs only on extensionpay.com payment pages to notify the extension when a payment or restoration completes. It does not read your personal spreadsheets, unrelated websites, or payment card fields.
Backups and deletion
Use Settings & backups to export, import, or reset local learning records. Resetting learning progress does not cancel a subscription or delete a payment-provider account. Use Manage purchase in Pro to manage billing. Removing the extension can remove local learning records; it does not itself cancel billing. Payment data deletion requests must also be handled by the relevant payment provider.
